Lack of quality seed and technical knowhow are considered major constraints to improving aquaculture productivity and profitability in Bangladesh. This paper assesses the outcomes of investments in improving carp seed quality and farmer training, targeting poor and women fish farmers, on the productivity and profitability of homestead aquaculture systems in Southwest Bangladesh.
Despite the success in fertilization and hatching of fish eggs with cryopreserved sperm, report on growth and survival of larvae produced from frozen-thawed sperm is inadequate. This study evaluates the applicability of cryopreserved sperm for mass seed production by comparing the growth and survival of a popular food-fish olive barb, Puntius sarana (Hamilton 1822) larvae produced from cryopreserved and fresh sperm.
Funded by the United States Agency for International Development (USAID), the five-year Aquaculture for Income and Nutrition (AIN) project improved income and nutrition for thousands of Bangladeshis.
The WorldFish Center is implementing the FtF Aquaculture Project in 20 southern districts in Bangladesh. The project is implemented under USAID’s Feed the Future initiative in collaboration with the Government of Bangladesh.
An account is given of research activities conducted in Malaysia regarding carpet shell clam seed production by artificial means. Serotonin injection resulted in egg and sperm release within 1/2-2 hours of receiving the injections. Details are provided of rearing procedures and diets.
Following a brief description of lake-based hatcheries and nurseries for tilapias, the advantages as compared to land-based systems are discussed, indicating also some of the disadvantages.
This study was carried out in order to understand the technical and economic characteristics of different Egyptian Nile tilapia (Oreochromis niloticus) hatchery systems. Hatchery operators at fifty tilapia hatcheries in four governorates were interviewed and four focus group discussions were held with 61 participants in March 2012.
Details are given of trials conducted in Thailand using the "hapa" system for nursing fish fry to fingerlings of the desired size for use in small scale aquaculture operations.
The hatchery technologies for Nile tilapia and African catfish training is a 5-day course designed for aquaculture hatchery and farm operators and managers, researchers, technicians, and extension workers. It provides hands-on training in modern aquaculture research and management techniques, especially in relation to tilapia and African catfish. The course includes the latest information on production methods shown to be reliable in the field, demonstrates updated technology for mass production of fish seed, and covers farming practices for different farming conditions.
