Aquaculture in Thailand is relatively recent. Formerly, there were ample freshwater fish in natural water bodies such as lakes, rivers and canals, but with decreasing catches due to overfishing, pesticide use, and a reduction in the flood plain fishery associated with the construction of irrigation systems, there has been a surge of interest in aquaculture. In contrast to the relatively well defined and stable Chinese system of integrated fish farming, Thai systems are characterized by instability since aquaculture in the country is experiencing a period of rapid evolution.
Fish—including finfish and shellfish—are an important item in the human food basket, contributing 17 percent of the global animal-based protein supply in 2010. They are an especially valuable food source in developing countries, where more than 75 percent of the world’s fish consumption occurs. In addition to protein, fish contain micronutrients and longchain omega-3 fatty acids that are essential for maternal and child health, but often deficient in the diets of the poor.
A brief account is given of a fish culture trial conducted in Malawi to determine the growth performance of Bathyclarias loweae and its potential for aquaculture.
Poster showing key steps in pond culture in Bangladesh
Bangladesh prides itself on being very rich in fish diversity. Its numeroud and diverse inland waterbodies and paddy fields are home to over 267 freshwater fish species. Biodiversity of fish species is important for nutrition and livelihoods of the rural poor in Bangladesh. There are promising fisheries technologies which have been developed and are being practised for improving fish biodiversity and nutrition.
The results are presented of a 2-year study conducted regarding management practices and problems associated with raising fish in concrete tanks in Nigeria. The location and construction of the tanks, which were used toculture Clarias gariepinus, Tilapia guineensis and Heterobranchus bidorsalis , are described, and suggestions made for overcoming the problems involved, which were mainly due to poor management skills. Major problems identified included incidence of "broken skull" disease in C.
The United States Agency for International Development (USAID)-funded Feed the Future Sierra Leone Agriculture Project supports the development of rice and fish farming systems to increase productivity and improve food and nutrition security and incomes. This factsheet outlines the key components. The project focuses on Tonkolili District, which has the highest prevalence of stunting and underweight among children under 5 in the country.
It is highly unlikely that wild capture fisheries will be able to produce higher yields in future. For aquaculture the opposite is the case. No other food production sector has grown as fast over the past 20 years. Aquaculture is expected to satisfy the growing world population’s demand for fish – and at the same time protect ocean fish stocks. Hopes are pinned on farming as an alternative to over-fishing. But the use of copious amounts of feed derived from wild fish, the destruction of mangrove forests and the use of antibiotics have given fish farming a bad name.
The aim of this study is to describe current chemical use practices in the aquaculture sector of Bangladesh and to identify the factors that influence them. A survey on the use of chemical and biological products was performed between November 2011 and June 2012 using structured questionnaires performed to producers of nine farm groups including homestead ponds, carps, tilapias, koi fish, shrimps, shrimps and prawns, only prawns, rice and fish, and pangas.
The findings are presented of a survey conducted regarding research on Mugil culture; emphasis was given to publications from the tropics and subtropics, particularly from developing regions. The literature search used ASFA, the ICLARM library and professional staff collections. It was found that during the period 1932-90 there were 203 articles published; of these, 41% were on the subject of reproduction, induced breeding and seed, 26% on culture systems, 12% on general discussions, 11% on diseases/parasites, and 10% on nutrition.
