Mola initiatives
Research started from BAU at 1991
DOF also initiated dissemination program on SIS at the same time
Afterward BFRI and other Universities have taken initiative for research
WorldFish started working on SIS during 2011 on pond aquaculture and enhancement in floodplain.
What is now People in many parts of the country accepted Carp-SIS polyculture technology DoF has taken initiative for dissemination WorldFish trying to promote small fish in pond aquaculture and floodplain in different part of the country BFRF, different universities also working on SIS

Introduction of SIS in pond polyculture
Average aquaculture production 2.23 mt/ha Pond aquaculture production 3.62 mt/ha Average contribution of SIS in pond aquaculture 10-15% Do not hamper carp production
Introduction of SIS into floodplain
Initiated by WorldFish during 2011-12. Stocked small qty. of mola during dry season in ditches and enforce regulation on harvesting during breeding season. - According to baseline survey there were no mola - After 1st intervention mola catch was 5% of the total production - After 2nd year intervention mola catch was 15% to the total production
Chalan Beel - the largest watershed
Haor area – Sylhet Mymensingh floodplain
Baor area – oxbow lake, dead river
Kaptai Lake – the largest man-made lake
Sundarbans – the largest contiguous mangrove forest of the world
Pond technology is being disseminated
in 7 districts
through 3 different interventions
(projects)
3 interventions, 3 different ways of engaging with communities
Intervention 1•2 year engagement•All farmers get mola•DoF involved•Lead farmers selected and trained to conduct further training with village farmers once every 15 days for 17 sessions
Intervention 2•1 year engagement•All farmers get mola•NGO involvement•Demo farmers selected and receive inputs•During stocking or harvesting, other farmers are invited onto the demo farmers plot
Intervention 3•1 year engagement•All farmers get mola•NGO involvement•Demo farmers selected and receive inputs•Demo farmers encouraged to share with other farmers•Project staff hold training on demo farm
The yield gap presents opportunity…….
*Figures have been standardized to tons per hectare per year
Small fish include: mola, punti, chela, delaha

Adding small fish has big implications for micronutrient production

CBFM is occurring throughout
Bangladesh.
Mola have been stocked in:
Rajsahahi
Mymensingh GaibandhaSunamganj
Mola ranked 6th in production volume

What do we need to do to take this to scale?
