Due to lack of sufficient technical knowledge and training on improved rice-fish culture which is expanding every day, many farmers are not getting optimum results in production. World Fish Center, from the start of the CSISA-BD project took the initiative to develop guideline for improved system for rice-fish culture. It was felt that there is a lack of efficient and skilled trainers and appropriate training materials.
Since 1961, global per capita fish consumption has nearly doubled. Much of the increase has been due to aquaculture. Bangladesh, the world’s eighth largest fish producing country, has been part of this transformation. Despite having vitamin A supplementation and fortification programs, the prevalence of inadequate vitamin A intake (IVAI) in Bangladesh is very high, estimated to be 60%. The promotion of a small indigenous fish, high in vitamin A- mola carplet - offers a promising food-based approach to improving vitamin A status of the 98% of Bangladeshis who eat fish.
There is growing appreciation of the role of aquaculture in diversifying livelihoods of the poor. However, prevailing cultural norms and values, and social relations often influence its development outcomes, which we explore in this study. Socio-cultural dynamics affect the capacity of resource-poor and marginalized groups for the adoption and retention of aquaculture technologies.
Fish is especially rich in essential omega-3 long-chain polyunsaturated fatty acids and micronutrients, including bioavailable calcium, iron and zinc. Fish features prominently in the diet of most, especially poor, Zambians. Despite this, its significance in the diet of women and children in the first 1,000 days is not well understood. Our current knowledge of the nutrient content of commonly consumed fish species in Zambia is synthesised.
Increase in demand of fish from Lake Victoria region has created gaps in local fish supplies and this raises concern since there are reports of limited animal-source food consumption plus protein and micronutrients deficiencies in this region. To fill the gap, less-preferred pelagic fish species such as Mukene (Rastreneobola argentea) and by-products from filleting Nile perch (Lates niloticus), which were commonly used for animal feeds, are increasingly being minimally processed and marketed for direct human consumption.
Small indigenous fish species (SIS) are an important source of essential macro- and micronutrients that can play an important role in the elimination of malnutrition and micronutrient deficiencies in the populations of many South and Southeast Asian countries. Of the 260 freshwater fish species in Bangladesh, more than 140 are classified as SIS and are an integral part of the rural Bangladeshi diet. As many SIS are eaten whole, with organs and bones, they contain high amounts of vitamins and minerals, including calcium, and iron and zinc. Some SIS, such as mola, are also rich in vitamin A.
Two sustainable, low-cost pond polyculture technologies have been developed to culture carps and mola in ponds, and culture carps and mola in ponds connected to rice fields. These technologies can increase total fish production from ponds. Farmers depend on carps as an income source, and mola is rich in micronutrients that can help to meet the nutritional requirements of the rural poor, particularly women and young children.
Hilsa was once abundantly available in the 100 rivers of Bangladesh. Fishermen used to catch plenty of hilsa which were sold fresh to the local and urban markets. It was a cheap fish and was affordable even to the poor. However, its population has declined significantly over the last 30 years. Such a decline in catches prompted the government of Bangladesh to declare four sites in the country's coastal rivers as hilsa sanctuaries restricting fishing during the breeding season.
