Adaptive Research Trials UnderCSISA-BD: Progress and Future Plan
o Culture of mola with carps in ponds and vegetableproduction in dikes/homestead areas by farming households2011 : Jessore and Rangpur2012 : Jessore, Rangpur, Mymensingh, Faridpur andBarisalField trial completed, data collection, entry, analysis to writearticle, working paper to be completed by October 2013.Important lessons learned will be shared.o Participatory Action Trial: Jessore, Rangpur, Mymensingh,Faridpur and Barisal set up in 2013. Guidelines to collectinformation will be provided useful to collect information todevelop science based outcomes.Integrated Homestead based Aquaculture
Cages for Fingerling and Foodfish Productiono 2011: Cages for Foodfish Production of Tilapia (GIFT, monosex – male)at Rangpur, Khulna and Barisal in beel, canal and rivero 9 women from poorest households in each area Total 27 womeno Designing of cages - 9 m3 nylon fixed net cages with simple metallicframeo Rangpur – set up in beel; Khulna – canal within polder 30;Barisal –river (initial), canalo Treatment: 3 stocking densities of fingerling (200, 300 and 400 perm3); used floating commercial feed.Cages set up in beel and canal waters showed success in production, poorresult obtained in river. Most cases the profit margin obtained was low ornegative due to high cost of fingerlings, high feed cost and price of fishsold is low.No significant variations in productivity related to stocking densities,higher stocking density resulted higher production with higher investment.
Cages for Fingerling and Foodfish Production2012: To get better understanding on input uses (fingerling, feed) andmarketing of fish the trail in Rangpur, Barisal, Khulna and Faridpur with56 women from poorest households.Results: Preliminary analysis showed…o Highly variable production and income among farmers within the samesiteso. Khulna : High mortality of fish in cages (>70%) due to less wateravailability, due to faster growth of fish survived showed good productionand in around 50% of them showed positive profit margin.o Major factors for low profit margin are found to be related to: sale offish at low price (Taka 111/kg although, the other household in the samesite sold Taka 150/kg).o Cages set up in river faced acute problems of water pollution, infestationby aquatic weeds and much mortality of fish, also more insecurity – cut ofcages and complete loss of fish
Cages for Fingerling and Foodfish Productiono Rangpur received high survival (>80%) but sold fish at very low price,purchased fingerlings at high cost and high FCR (>2.5), however for onefarmer in same site the FCR is 1.4 who received very high profit margino Barisal: 4 cages in one location (Fadiabaza, Lebukhali, Dumki) and 5cages set up in Seali, Badrapur in Potuakhali. Very high performancewith higher profit margin in 1st cycle by all in Lebukhali and it is expectedto be doubled in 2nd cycle (on-going), along with higher efficiency inproduction, feed use, selling of fish at premium price is importantly cameout for such results.o Faridpur – cages set up in Faridpur in river showed poor outcomes2013 and onwards - participatory adoption trial (PAT), Rangpur, Khulna,Barisal, no financial support, they do the operation using their ownfunding (kept as revolving funding. Will develop a CN on monitoring ofthe research with the farmers [Participatory Monitoring Trial in Rangpur,Khulna, Barisal and Faridpur
Improving Quality Fish Seed Productiono All Hubs: Conducted Hatchery Survey (Carp, Tilapia and Pangus 300hatcheries) and Organize Stakeholder Workshopso Rangpur & Mymensingh selected contact hatcheries (30 hatcheries; 13carp 2 tilapia in Rangpur; 7 carp and 8 Tilapia in Mymensingh)o Organize meeting/workshops with selected hatcheries and expertso Collection of detailed information of the hatcherieso Development of Technical and Business Plan (draft plan completed)o Establish Breeding Nucleus in private hatchery using 14th generation ofGIFT imported from WorldFish Malaysia (through FtF AquacultureProject)o Distribution of improved germplams of rohu, catla, mrigal collectedfrom RFLDC-Danida contact hatcheries origin from Halda River andBFRI.o Plan to distribute improved germplasm of GIFT to all the contacthatcheries (9) for development of improved broodfish to use in 2014.o Plan to establish a BN in Rangpur Hub for tilapia
Technical and Business (T&B) PlanDevelopmentPurpose: To establish the system for production and supply of improvedquality fish seed in a sustainable way CSISA-BD project is developingthe T&B Plan.o 30 Plans (one for each hatchery; 13 carp and 2 tilapia hatcheries inRangpur and 7 carp and 8 tilapia in Mymensingh) for 10 yearso Experts – Faculties and students from Biology and GeneticsDepartment of BAUo T & B plan will be provided to the hatcheries by September 2013.o Sample of one plan (shown)
