Importance of Natural Resources

RSTV Eureka – Relevance on Inland fishery & fishery science



welcome to this episode of Eureka and we are going to have a very interesting and very exciting conversation with dr. BK Das who is the director of central inland fisheries Research Institute a constant unit of ICAI Indian Council for agriculture research do you know out of the total fish availability today something close to about fifty percent come from inland fisheries though the fish immediately evokes us only the image of sea Inland Fisheries is very important before we start our conversation let's take a quick look at his brief profile Keep Watch America inland fishery contributes around 60% to the India's total fish production but over the recent years inland aquatic resources are gradually depleting with environmental contaminants according to fisheries experts aqua life conservation and restoration are key for the sustainable management of aquatic ecosystems dr. basanta kumar das is one of the leading fish health management scientist of the country who is working in this sector and currently he is the director of the ica our central inland fisheries Research Institute Kolkata and also the president of inland fisheries Society of India dr. das did his bachelor's master's and PhD from College of fisheries ERISA University of agricultural technology boognish world and after that he did post doctorate in fish immunology from a bbm University UK in the year 2006 2007 and also went for his second post doctorate in nanosensors from university of california USA in the year 2010 his research is mostly concentrated on aquatic animal health management along with prospecting noble biomolecules of industrial application of global importance dr. das has published many international research papers and developed medicines for ornamental fish diseases and molecular diagnostic kit for tilapia leak virus besides the technology like GI cage HDPE pen cage grow feed for fish which were commercialized he has also registered the design of the tissue embedding machine in the Patent Office he did lots of extension training programs for capacity building in fish disease management and inland fisheries management for the farming community of the country dr. das has received numerous awards and honors including best Indian fishery scientist by professional fisheries graduates forum India and crucial Ratna and crucial Gaurav Award in the year 2016 and 17 respectively and he's among the most cited scientists in the fisheries sector thank you for being with us it's a very wonderful opportunity it's a very nice Institute with 70 years of legacy and you are hitting this institute at a crucial time when India is planning to increase its production in food and also increase the farm income by at least twice I mean we know that there is a huge crisis in agriculture and we need to come out of it the farmers how to have a better deal we know about it let me start with this question I mean usually people think when we talk about fish oh and the Fisher people who are living in the edges of ocean who go into ocean to fish how important is inland fishing if we see the ocean concept in the earlier in nineteen fifties only the capture fisheries from the ocean contributes more higher agent today the inland fisheries contribute 65% of the fish production of the India in which a ground eighty percent comes from the aquaculture and the rest persons comes the inland fisheries again inland fisheries contribute 1 million metric tons to the sector also and not only the research they leave take their livelihood from the motion but he puts a 12 million of fishers they are dependent upon these inland sectors with the lake rewarded reserved words besides the person's entrepreneurs they are dependent in the aquaculture sectors the resources very used in India sick looking at the diversity of the type of the fish that he found in this and a rich biodiversity hotspot in the country agile in the globe and if we look into the prosperity of the inland sector when government our Honorable Prime Minister is forecasting the doubling farmers incomes the only sector after if you look into the animals and specially the only sectors which can double the farmers incomes that were projected by 2022 this institute is having a huge legacy of 70 years I mean you are heading the Institute now but if somebody has to ask you that what this institute has done in the 70 long years for nation building what would you put as main points look into this the institute was born in 17th March 1947 it's a pre independent Institute it is a second Institute after central Marine Fisheries Institute in the sector for the sectoral development and it is given birth to another four Institute like central inland of Central Institute of ratio aquaculture central into a brackish to attract work culture the Directorate of cold water fisheries and National Bureau fish genetic resources people see it brings into 1985 these four Institute before to date it is so much eople making technologies like Indians breeding technology which leads to the blue revolution in the country and which the piece you are available in any time in the plate nowadays because of this induced breeding it was born don beyer can you just describe this induced bleeding a bit more i mean how does it actually make fish available all through the seasons India's breeding technologies artificial hypothesis ins generally fish do not breed the cars do not breed in a confinement and they required a simulation conditions so dueting hypo physicians putting the hormone injections pituitary glands the first induced breeding was done by dr. awakuni and dr. Harrell L Chaudhary is a remote place of Orissa that own ogle and killer fish ponds where did the fish breathe and during the breeding was controlled so India or the scientists can breed anytime in it for fish and get the spawn and finger links that are available for the culture practices these techniques that was developed the river Lina says the car culture technology in the country later we give this so much training to the foreign governments and foreign institutions and sefa and there is effort it's a freshwater aquaculture is our training as I saw where the network of aquaculture Center Pacific the lead center regional lead center where it gives so much training to the multinational again to propagate to this the second technology comes be composite fish culture technology ok composite fish culture technology the culturing of fish is a multiple culture six phases compositions taking into in that niche of the ponds where the top layer burrito fish which is Jay Cutler and silver carp and the columnar is Roe and grass carp bottom layer is mega length common calf so this is like you are trying for multi cropping in agriculture form you are saying that using the three-dimensional you know situation in a water source you are saying that we can grow multiple kind of fish in the same point that's what yes yes again we have the third technology recently we have the serious one the creates culture case culture we have largely more of reservoirs in the small medium and major reserved person and we have advised the kids culture in a medium and large river reservoirs taking 0.1 percent of the water area into the case culture and here it will say cage of dimension of 90 meter cube water area you can grow minimum of 3 tonnes field that is a panga see Odin – alamos a small water Vaidya growing so much free fish is a huge potential for this sector also and see if we also designed a case and he changed when commercialize this year in the platinum jubilee year ok ok so you are talking about three major contribution one is that I mean growing copper fingerlings at different time I mean second is multiple fishers in the same pond I mean and the third of this cage any other major challenges that you solved in the 70 years so we solve major challenges like pen culture which in wetland CJ major area so in situ the airing of the fingerlings in the pen and again this pen will be also a biodiversity it will seem to increase the biodiversity of these wetlands because it is felt that wetlands are the heart of this any of the facility all the activities major activity takes plane the Outlands again the Institute has worked in the Ganga river system for the biodiversity conservation okay we are the partner of NMC gentleman know Miami Ganga programs again he'll say a major price for a piece like by this region of the country the Institute to work dedicatory for the hills of fisheries and recently for last five-person collaboration sniffing river we are trying to develop the captive breeding of the Hilsa which if he'll same ever level in the pond then even people in the bengal orissa and these regions they like been following this a high-value spaces and again now we are thinking for doing some of the conservation and productivity enhancement in the inland open waters like wetlands reserve birds and rivers in which earlier different ate the productivity of these reservoirs is less than 50 kg now because of the secrecy freeze interventions and governance pattern to the respective state governments and this has been increased more than 250 kgs okay from 50 to 250 yeah that's some reserved words you will find it has gone up to 1,250 kg also okay to average production we have gone up to 250 kg that's a very very interesting aspect of how your Institute has contributed to increase in the productivity of Inland Fisheries particularly in you know dams and other when water reservoirs we'll have to take a very short break we'll continue this conversation we'll take a very short break don't go away do you know next – milk fish is the main source of non-vegetarian protein in India it's a very very important sector for not just making the income of farmers but also for food security in India we'll continue this conversation keep watching Eureka welcome back to a record and we are having a very interesting conversation with dr. BK das who is the director of central inland fisheries Research Institute which is a constituent of Indian Council for agriculture research do you know at the time of Independence the fisheries contributed to about 0.5 grams of protein per day per capita but today it has increased about 3.5 grams protein per capita per day this is a substantial increase and if we want food security and if we want people to have a healthy life protein is a very important aspect and fish is a one of the major source of protein in India we are having a very wonderful conversation of how this Institute has contributed to the nation-building before the break now I am going to talk about something very interesting he is a doctor you would have heard doctor who are treating humans may be your pets veterinary doctor he is a fish doctor you are a fish doctor that's a very very interesting idea many of us won't even know that such a profession existed how did you land up in this situation if you look into these things when I am in school so I belonged to a backwater area of balusters distrito Parisa okay many my schooling days I went to fishing also so when I completed my science and appeared in the agricultural examinations I find to prefer to take the fishery science as a subject I have never looked back whether an agricultural sciences veterinary sciences and engineering seats are vacant so quickly we choose this profession soon after that our completion of my master's degree then I got the erase examinations and I am fond of taking this education and fortunately I was done my PhD and master degree on disease under the guidance of doctors Subash Chandra Mukherjee was the expert in disease then I have a fascination since then I work on the menu various aspect of disease diagnosis control and advising service to the farmers very very interesting let me ask you this question most of us would not know about it so it's a very curious circuit and see if I am will I go to a doctor the doctor looks at my puzzles maybe use a stethoscope maybe put a thermometer maybe put me through a lecture a scan machine if your pet your dog are let's say even your cow that is in your house is in the vet daily doctor comes and does examination so how do people actually know there is a disease to a fish and how do you actually identify those diseases you see it's a critical question you've asked because fish never speak yeah the terrestrial animal speak please never speak but when is very sick he will come to the surface of the water okay that is the first symptoms of diagnosing a sick fish again second thing is when you go for sample netting sample netting then you will find some of the sickness and we diagnose now without any of the instruments mostly the clinical observations and the behavior of this piece they no identify in the first line of defense because we have to set the loss first by the farmers there we have it treatment strategy advise some of the strategy for treatment to the farmers again would bring the samples to the laboratory for the different level of diagnosis and after diagnosis and we again suggest if the fish is still more there is mortality then again were versed to check the mortality so you have been working in developing treatment strategies and medicines and also how to treat this sick fish organisms right so what would you say as something that you felt very happy in your own research carrier something that you developed which actually had a impact you will see in my 22 years of research career as a scientist at various capacities the initial phase of the life we work mostly in the breeding and other things like the Institute mandate later in 2000 I have worked on the disease aspect since then for it will ship for the national importance we have worked when my PhD later part we have like a formulations or the cypermethrin they wear a pesticide that are used for controlling the argue Lois it's a dreaded disease in the Rojo culture and with that so many formulation my industry has come up and they're controlling processes going on it in cypermethrin in the various trade name again we have a formulation I have brought out that is known as c4 cure controlling the ornamental fish diseases the bacterial fungal diseases then I have worked with this effects they part of this latter part for controlling various epazote calciatori syndrome which is a causative organism and added provisions in the freshwater aquaculture thirdly I have worked some of the part latter part of the vaccine development along with the CCM B we have worked on the DNA vaccine of e ta da and that process and I have developed a polyvalent vaccines and we tried to years back in Andhra Pradesh with the oral delivery systems giving in the field and it found it is very successful the whole idea of this vaccination strategy they were Andhra Pradesh if will see every 100 metres there is a fish doctor is sitting and they are much lot of chemicals to be used in aquaculture to make a safe face to eat with order to at least 20% replacement of these chemicals it's a very very important area in which our Institute has been working for quite long right so what is the scenario of Inland Fisheries in India what is the kind of grow that we are seeing how many people are involved how many much area is involved what's a scenario tree if you look into the inland fisheries sector exploding aquaculture if we see 12 million people are dependent upon the inland tricked sector and look at the Ganga river system which goes from Gangotri to Ganga Sagar and most of the 60% of the populations are dependent on fishing and we have studied that the average income is 3000 initially to 3000 rupees and only last year we again have studied and it has gone to 7,000 rupees in this and the fishing and that much of this amount that fisherman brings from the natural system and she's a very less and is a sectoral development we always think that increasing the biodiversity and giving a conservation values to this and Sam closely the livelihood officials research can be more so for that we always talking with the NMC gene with the things we have taken a program under national mission for clean ganga for the ranching aspect of the river ganga in which what was ranching aspect ranching or amines the collecting the bruders from the same environment okay and the breeding in their confinement again releasing the finger links into the Ganga or same river from where you have brought one of the problem or one of the change what can say it not be a problem but it's a challenge actually but if you look at something like River once upon a time it used to flow from its origin to you know version almost unimpeded right so if there is a fish species over there it can use almost the whole part of the river are a large part of the river now your dams you have lots of obstructions right so it means that we have in a way impeded the natural ecosystem of many aquatic life right how does it affect your open source system like a river and how are you taking up the challenge you see ecosystem health is a major things that we have to consider people's independence we have very few dense now ever thirty thousand dreams has come in the major river systems that is needed also because we require irrigation we want to increase the agricultural product zones we use want to use water judiciously that in but besides that we should look into the equal life that is minimum environment Pro we have constructing dam and viruses so we have given the guidelines to CWC and different Bureau of Indian Standards to make the minimum environment flow to make the health of the rivers to a leap and restoring the equal life take the minimum and mental flow is there then feature level to breathe then if a breathable living will be there then equal life can be destroyed that's interesting so but even when in the current situation the aqua life should have reduced rate I mean the number of species would have reduced the number of speak I mean life forms in each of these pieces would have also reduced right so how are you tackling this reduction in the biomass within the open systems you look into this we have studied maybe twenty years thirty years in time scale the biodiversity drastically reduce then there is a climate change in global warming so we are looking for some of the climate resilient spaces like China or pond tears these are the some of the spaces are climate resilience so we are advising to have a breeding value of this climate resilient spaces that can be restocked for the biodiversity conservation of point of view no besides this talking for the farmers for their livelihood so these faces and we were addressing to the state government because this Fisher is a domain of states and we are advising the state government and national biodiversity authorities and other governmental and ngos to work upon it and have a respective guidelines again we have a our niskin farmer sensitization sir Fisher sensitization is the one of the issues but like message regulations then closed regions these are the some of the issues you are addressing and timely we are wasting to the government and sensitizing the Fisher's to do these things see for the dams and other kinds of obstruction are one of the major challenges of open systems if you look at surface water like a pond or you know small water body the leaching of pesticides and other chemicals that we put in agricultural land into this water body would be a major challenge right what kind of impact that it has had on a qualif and also fisheries if you look into the one of the study was done in the Ganga river the Milt was available in 1950s maybe forty five liters now that Milt is reduced to 15 liters this indicates the fishes are not breeding or the broad fishes gradually coming down and the young one that are being recruited when is go to the smallest age into the wetlands there because of pesticide runoff other things that is calm down again if we'll see earlier in 30 years well the benefits are reaching this type of fishes and anybody belongs to a village life would have seen and could have got in there Freddie fritz and today the system is totally change we do not find any of the fish in the paddy field except some of the organic states like if we'll see in the northeastern states there are some states they go for Predacon fish culture you can find because okay they are completely organic same to look into this aspect we should have a definite likely for somebody because it is relating to our breeding is related the Munchen again all this cropping also agricultural coping related the main promotion but we should see some of the pesticides in the fourth generation which are being used they are biodegradable within 10 to 15 days ok so the farmers should be sensitized and because of the sensitization it will reduce the you jobs and and use it judiciously in the sector then we can have a concept to set the equalized future also that's ok so now we don't have much time in this show but this question I need to ask you what do you think are three major challenges in inland fisheries which as I Institute you would like to take up today I mean when we are entering into this new era we are one of the propagating the inland sectors the productivity enhancement which is you are looking with the state governments second is bringing this sector is a vibrant in a safe environment contaminate support mapping the water bodies in the river reservoirs in terms of pollution index and third one is this small indigenous fish conservations and it will be available to this resource for their livelihood and these are the three things behind it we have done a study SIF small and indigenous speed how it is increasing the protein values increasing the DJ reducing the diseases of the rural people we have studied in sons urban areas taking 30 woman beneficiaries in the account we have studied their initial blood profiles after feeding and one month we have seen so many serum profile have increased and enemy conditions are gradually reducing again we have a challenges we have categorized 100 nutria fish index where it is the protein carbohydrate fats amino acids and micronutrients some fish are rich in iodine some fish are rich in manganese if we take this fish then instead of taking the capsules for the micronutrient vitamins okay and you can reduce that thing so then that is again we are trying to partner with the World Bank nutrifreeze 1000 where you can address across the globe also the importance and he says another concern we are trying to address this is a major challenges because if in Bangladesh and India here you fully GB and Ganga Brahmaputra Magne Magne way since we are trying to collaborate with the Norwegian government other things to see the answer to be bred in the fonts also okay it's a very very important sector what do you think are some of the major area that we should now focus so that our this sector can be you know secured and also developed further if we see today production is ten point eight million metric ton out of that shrimp is being exported the domestic injection is new for local 2d the requirement of per capita fish is used and H for 19 kg people say that that thinks about radiant is like 11 kg weird things and who is demanded there and domestic sector is also controversial that you require a village and besides research component whatever the piece they produce in the perm get if you do not get a price like agricultural products so the farmers will be disappointed to promote industry in the aquaculture and Fisheries in the sector we require evolution systems like which a cold storage the marketing channels then like the e market for the fisheries the farmers will get the good benefit of the at the porn sites these are also the hurdles to promote the inland sector in a big way ok that's a very interesting point and with this we need to in today's conversation it's been a very enlightening very informative conversation thank you for being with us in the show keep watching Rica we'll come back with another conversation next week
