Training manual on improved shrimp culture in Gher: A course manual for shrimp farmers

Due to inadequate technical knowledge and training in advanced methods of gradually growing shrimp culture, framers are not getting expected yield. From the very beginning of the CSISA-BD project, WoldFish Center has taken initiative to introduce advanced methods of shrimp culture in south-west of Bangladesh. To do this, the shortage of skilled trainers and training materials, has, particularly, been realized.

Strategic review of the fishery situation in Thailand

Fisheries are an important source of animal protein for most of Thailand’s population, particularly in provinces on or near the coast. Between 1978 and 1997 the per capita consumption of fish averaged 24 kg·capita-1 annually. In 1995, about 535 210 people were involved in the fisheries sector and 44% of these were engaged in small scale marine capture fisheries. Since 1982, Thailand has faced problems with the development of marine capture fisheries and their over-exploitation which has increased fishery conflicts and disputes with neighboring countries.

Socioeconomic and bioeconomic performance of Philippine fisheries in the recent decades

The fishing industry in the Philippines was tantamount to a marine capture fishery in the 1950s to 1960s. Aquaculture and inland fishery production were not significant. Only during the 1970s did aquaculture and inland capture fisheries contribute significantly to fish production. From 250 000 t fish production in 1951, this increased substantially to 1.6 million t in the 1990s. An average 4.3% was contributed by fisheries to the gross domestic product from 1988 - 98. Fisheries export earnings reached P12 billion in the 1990s.

Small-scale aquaculture: Global and national perspectives

Fish has been a staple food for over a billion people. Its demand is increasing due to growing population and awareness about health benefits of aquatic animal food. Disappointingly, wild catch worldwide is on the decline and aquaculture is emerging as the only solution. It grew at 9%/yr in the last 10 years becoming the fastest growing food production sector. At present, aquaculture produces only about 45 million t per year but it needs to be doubled by 2030 to meet its growing demand. Asia produces over 85% of the global farmed fish - mostly by small-scale farmers.

Shrimp processing in Bangladesh

The shrimp industry in Bangladesh is the major fisheries foreign exchange earner. The various processing industries consist of freezing plants, smoking/drying factories and meal factories. Details are given of the freezing plants ofBangladesh, quality control laboratories and smoking factories, and also the various shrimp products produced. Suggestions are made for improved production.

Reduction in effort and favorable environment helped to increase shrimp catch in Kuwait

The 1988-1989 shrimp catch from kuwait waters was 5125 t, representing a 62% increase above the previous record of 3158 t in 1966-1967. Ninety-eight per cent of the record landing was comprised of Penaeus semisulcatus (Penaeidae). The attainment of optimal spawning-stock biomass by reduction in effort, protection of small recruits through delayed season opening, as well as strict enforcement of closed nursery areas, and occurrence of two strong recruitment pulses due to favorable environmental conditions in 1988 appear to be the major reasons for the increase.

Quantitative genetic parameter estimates for body and carcass traits in a cultured stock of giant freshwater prawn (Macrobrachium rosenbergii) selected for harvest weight in Vietnam

Benefits derived from selective breeding have been demonstrated in livestock and in some fish species, but by contrast, there have been few systematic selection programs reported for shrimps. Improving growth rate has been identified as the most important trait in the breeding objective for cultured shrimp species. In the present study we analyzed a four generation data set from a fully pedigreed selective breeding program for giant freshwater prawn (GFP in Vietnam. We estimated phenotypic and genetic parameters for body and carcass weight traits.

Profitability and adoption of improved shrimp farming technologies in the aquatic agricultural systems of southwestern Bangladesh

This paper assesses factors influencing adoption of new shrimp aquaculture technologies within aquatic-agricultural farming systems in southwestern Bangladesh. The impacts of three new technologies were assessed: two Modified Traditional Technologies (MTT 1 and MTT 2) and a Closed System Technology (CST). A total of 789 farmers from 10 sub-districts in Khulna Division were surveyed randomly, including a control group of 350 farmers using traditional technologies.
