This document summarizes several adaptive research trials being conducted under the CSISA-BD project. It discusses (1) participatory trials on integrated homestead aquaculture and vegetable production in several districts, (2) cage trials for fish production with local women, (3) efforts to improve quality fish seed production including developing technical plans for hatcheries and distributing improved broodstock, (4) establishing tilapia breeding nuclei, and (5) plans for a participatory action research on improving benefits from homestead ponds. The projects aim to develop science-based aquaculture practices and improve livelihoods through local participation and adoption of integrated farming models.

1. Adaptive Research Trials Under
CSISA-BD: Progress and Future Plan

2. o Culture of mola with carps in ponds and vegetable
production in dikes/homestead areas by farming households
2011 : Jessore and Rangpur
2012 : Jessore, Rangpur, Mymensingh, Faridpur and
Barisal
Field trial completed, data collection, entry, analysis to write
article, 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 collect
information will be provided useful to collect information to
develop science based outcomes.
Integrated Homestead based Aquaculture

3. Cages for Fingerling and Foodfish Production
o 2011: Cages for Foodfish Production of Tilapia (GIFT, monosex – male)
at Rangpur, Khulna and Barisal in beel, canal and river
o 9 women from poorest households in each area Total 27 women
o Designing of cages - 9 m3 nylon fixed net cages with simple metallic
frame
o Rangpur – set up in beel; Khulna – canal within polder 30;Barisal –
river (initial), canal
o Treatment: 3 stocking densities of fingerling (200, 300 and 400 per
m3); used floating commercial feed.
Cages set up in beel and canal waters showed success in production, poor
result obtained in river. Most cases the profit margin obtained was low or
negative due to high cost of fingerlings, high feed cost and price of fish
sold is low.
No significant variations in productivity related to stocking densities,
higher stocking density resulted higher production with higher investment.

4. Cages for Fingerling and Foodfish Production
2012: To get better understanding on input uses (fingerling, feed) and
marketing of fish the trail in Rangpur, Barisal, Khulna and Faridpur with
56 women from poorest households.
Results: Preliminary analysis showed…
o Highly variable production and income among farmers within the same
sites
o. Khulna : High mortality of fish in cages (>70%) due to less water
availability, due to faster growth of fish survived showed good production
and in around 50% of them showed positive profit margin.
o Major factors for low profit margin are found to be related to: sale of
fish at low price (Taka 111/kg although, the other household in the same
site sold Taka 150/kg).
o Cages set up in river faced acute problems of water pollution, infestation
by aquatic weeds and much mortality of fish, also more insecurity – cut of
cages and complete loss of fish

5. Cages for Fingerling and Foodfish Production
o Rangpur received high survival (>80%) but sold fish at very low price,
purchased fingerlings at high cost and high FCR (>2.5), however for one
farmer in same site the FCR is 1.4 who received very high profit margin
o Barisal: 4 cages in one location (Fadiabaza, Lebukhali, Dumki) and 5
cages set up in Seali, Badrapur in Potuakhali. Very high performance
with higher profit margin in 1st cycle by all in Lebukhali and it is expected
to be doubled in 2nd cycle (on-going), along with higher efficiency in
production, feed use, selling of fish at premium price is importantly came
out for such results.
o Faridpur – cages set up in Faridpur in river showed poor outcomes
2013 and onwards - participatory adoption trial (PAT), Rangpur, Khulna,
Barisal, no financial support, they do the operation using their own
funding (kept as revolving funding. Will develop a CN on monitoring of
the research with the farmers [Participatory Monitoring Trial in Rangpur,
Khulna, Barisal and Faridpur

6. Improving Quality Fish Seed Production
o All Hubs: Conducted Hatchery Survey (Carp, Tilapia and Pangus 300
hatcheries) and Organize Stakeholder Workshops
o Rangpur & Mymensingh selected contact hatcheries (30 hatcheries; 13
carp 2 tilapia in Rangpur; 7 carp and 8 Tilapia in Mymensingh)
o Organize meeting/workshops with selected hatcheries and experts
o Collection of detailed information of the hatcheries
o Development of Technical and Business Plan (draft plan completed)
o Establish Breeding Nucleus in private hatchery using 14th generation of
GIFT imported from WorldFish Malaysia (through FtF Aquaculture
Project)
o Distribution of improved germplams of rohu, catla, mrigal collected
from RFLDC-Danida contact hatcheries origin from Halda River and
BFRI.
o Plan to distribute improved germplasm of GIFT to all the contact
hatcheries (9) for development of improved broodfish to use in 2014.
o Plan to establish a BN in Rangpur Hub for tilapia

7. Technical and Business (T&B) Plan
Development
Purpose: To establish the system for production and supply of improved
quality fish seed in a sustainable way CSISA-BD project is developing
the T&B Plan.
o 30 Plans (one for each hatchery; 13 carp and 2 tilapia hatcheries in
Rangpur and 7 carp and 8 tilapia in Mymensingh) for 10 years
o Experts – Faculties and students from Biology and Genetics
Department of BAU
o T & B plan will be provided to the hatcheries by September 2013.
o Sample of one plan (shown)

8. Distribution of Improved Germplasm of Carp
Purpose: Use of high quality broodstock quality for production of improve
quality fish seed
