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.

Shrimp (Penaeus monodon) farming in the coastal areas of Bangladesh: Challenges and prospects towards sustainable development

This chapter mainly presents the history of shrimp aquaculture in Bangladesh and impacts of shrimp farming on rural livelihoods with particular focus on income and dietary consumption, based on literature reviews and structured field surveys.

New skill with determination changed Lalita’s life

Lalita Bala is learning music from a professional singer. It was a long cherished desire she could not realize, being the daughter of a poor farmer and married when she was only 15. Now 25 years old, she is a mother of a 5-year-old child.

Quantitative genetic parameter estimates for body and carcass traits in a cultured stock of giant freshwater prawn 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.

Mobile Fish Hatchery and PCR tested shrimp seeds radically increases Spawn and shrimp production in Bangladesh

The Halda River is the best pure Indian carp breeding river in Bangladesh and the major source of naturally produced carp fry. But traditional method of egg hatching often leads to low hatching and survival rates of spawn.

Governance of Global Value Chains in Response to Food Safety and Certification Standards: The Case of Shrimp from Vietnam

We use global value chain (GVC) theory to understand governance of Vietnam’s shrimp farming industry. We describe this GVC as buyer-driven with important food safety standards imposed by governments of importing countries and new certification systems promoted by nongovernmental organizations (NGOs).

Autonomous adaptation to climate change by shrimp and catfish farmers in Vietnam’s Mekong River delta

Kam, S.P. ; Badjeck, M.C. ; Teh, L. ; Teh, L. ; Tran, N. 2012. Working paper 2012-24. WorldFish. Penang, Malaysia

The Mekong River delta of Vietnam supports a thriving aquaculture industry but is exposed to the impacts of climate change. In particular, sea level rise and attendant increased flooding (both coastal and riverine) and coastal salinity intrusion threaten the long-term viability of this important industry. This working paper summarizes an analysis of the economics of aquaculture adaptation in the delta, focusing on the grow-out of two exported aquaculture species—the freshwater striped catfish and the brackish-water tiger shrimp. The analysis was conducted for four pond-based production systems: catfish in the inland and coastal provinces and improved extensive and semi-intensive/intensive shrimp culture.

Breeding improved prawns in India

India has enormous freshwater and low saline brackish water resources that can be utilized for freshwater prawn farming. Since the mid-1990s, production of the giant river prawn (Macrobrachium rosenbergii) has boomed, making India the second largest freshwater prawn producer in the world. Over recent years, prawn production has been declining, threatening the ongoing success of the prawn industry, and the livelihoods of the communities it supports. The Genetic Improvement of Freshwater Prawn project aims to safeguard the future of the prawn industry in India through the establishment of a selective breeding program for high quality prawn stock.
