Smallholder aquaculture: sustaining the impact of private investment

The growth of aquaculture - now the fastest growing food production system in the world - is increasingly attracting private investment. Much of this investment, however, is in larger enterprises and input services such as feed, seed and processing. Little is targeted at smallholder farmers who, as a result, continue to face constraints in accessing finance, technology and markets. In 2010, WorldFish set out to explore the business case for investment in smallholder aquaculture by examining several donor funded projects.

Small-scale aquaculture for rural livelihoods: Proceedings of the Symposium on Small-scale aquaculture for increasing resilience of Rural Livelihoods in Nepal. 5-6 Feb 2009. Kathmandu, Nepal

Over the years, aquaculture has developed as one of the fastest growing food production sectors in Nepal. However, local fish supplies have been extremely inadequate to meet the ever increasing demand in the country. Nepal imports substantial quantities of fish and fish products from India, Bangladesh, Thailand, and elsewhere.

Shrimp, prawn and the political economy of social wellbeing in rural Bangladesh

Wellbeing is gaining prominence in international development discourse as an alternative means of conceptualising and assessing progress against human development goals. This paper operationalizes the concept of social wellbeing (comprised of interlinked material, subjective and relational dimensions) as a framework for understanding the effects of agrarian change, as experienced by inhabitants of two villages in rural Southwest Bangladesh.

Sea cucumber culture, farming and sea ranching in the tropics: Progress, problems and opportunities

Tropical sea cucumber mariculture has potential to become a profitable industry and contribute towards natural population replenishment. Here, we synthesise the fields of progress, current impediments and research opportunities in tropical sea cucumber aquaculture arising from recent studies and an Indo-Pacific symposium. We present novel comparisons of data from hatcheries, earthen ponds and sea pens from published and unpublished studies in various countries. Of the few tropical species to have been cultured, only the sandfish Holothuria scabra has been bred extensively.

Review of the history, status and prospects of the black tiger shrimp (Penaeus monodon) hatchery sector in Bangladesh

Culture of shrimp, mainly Penaeus monodon, makes an important contribution to Bangladesh's aquaculture industry. Shrimp hatcheries are the foundation on which the shrimp industry is built. Hatchery performance and management therefore has extremely important implications for the long-term viability of the entire shrimp sector, especially given its vulnerability to diseases such as white spot syndrome virus (WSSV).

Reuse of fish pond sediments as fertilizer for fodder grass production in Bangladesh: Potential for sustainable intensification and improved nutrition

Intensive aquaculture systems (e.g. pangasius farming) make important contributions to food security in developing countries, including Bangladesh, but are associated with a variety of negative environmental impacts, including the discharge of nutrient rich sediments into local ecosystems.

Response to selection for growth in an interspecific hybrid between Oreochromis mossambicus and O. niloticus in two distinct environments

The development of a saline tolerant tilapia strain able to grow fast is of importance in the Philippines, where 240 000 ha of brackish water ponds are available. To this end, founder hybridization between Oreochromis niloticus (with favorable growth traits) and O. mossambicus (with favorable salinity tolerance traits) was performed and followed by backcrossing with O. mossambicus to develop a strain highly tolerant to saline environments. Genetic selection for growth performance was subsequently conducted.
