Breeding plan for common carp (Cyprinus carpio) in Indonesia: multiple-trait selection.

Total aquaculture production in Indonesia in 1994 was 493 000 tons of finfish, 169 000 tons of shellfish, mainly shrimp and 115 000 tons of seaweed with an estimated value of US$ 2 075 million. In 1994, the production of common carp (Cyprinus carpio) was 135 200 tons, from ponds (52 600 tons), cages (28 600 tons) and ricefields (54 000 tons). The potential for aquaculture in Indonesia is large. The mangrove forest area is estimated to be around 4.29 million ha. It is recommended to use only 20 % of the total mangrove area for aquaculture production (830 900 ha).

Impact of long-term training and extension support on small-scale carp polyculture farms of Bangladesh

One of the unique features of the Development of Sustainable Aquaculture Project of the WorldFish Center, Bangladesh, was the provision of 3 y of continuous training and extension in support of the fish farmers involved. It was expected that the long-term support would make a significant contribution to boosting production and incomes as well as sustainability. The article demonstrates the impact of the training and extension support to small-scale carp polyculture farmers in terms of productivity, profitability, and efficiency.

Mass selection for increased body weight at harvest over five generations in silver barb, Puntius gonionotus

Silver barb (Puntius gonionotus Bleeker 1850) is an Asian carp that is popular as a food fish. It is distributed throughout Thailand in rivers, canals, reservoirs and swamps. It is also cultured in ponds and paddy fields. Its production from aquaculture in 2003 was estimated at 49,066 f metric tons (14 per cent of the total fish production), and valued at 34.6 millions US dollars, ranking third among freshwater fishes cultured in Thailand. However, the performance of many hatchery populations of silver barb is low, mainly due to a lack of improved stocks.

Assessment of the carp seeds value chain in Southern Bangladesh

The Aquaculture for Income and Nutrition (AIN) project implemented by World Fish and funded by USAID, aims at increasing aquaculture production in 20 districts of Southern Bangladesh (Greater Khulna, Greater Barisal, Greater Jessore and Greater Faridpur) to reduce poverty and enhance nutritional status. As part of its initial scoping activities World Fish commissioned this value chain assessment on the market chains of carp fish seed (spawn, fry and fingerlings) in the southern region of Bangladesh.

The characteristics and status of pond aquaculture in Bangladesh

Very rapid developments are widely believed to have occurred within Bangladesh's aquaculture sector in recent years, but have yet to be adequately documented. This paper addresses the information gap based on a comprehensive review of literature and data. The current status of pond based aquaculture in Bangladesh is summarized in terms of the quantities and species of fish produced and the technical and social characteristics of the production systems from which they originate.

Carp-SIS polyculture: A new intervention to improve women’s livelihoods, income and nutrition in Terai, Nepal

Based on lessons learned from field trials, carp-small indigenous fish species (SIS)-prawn polyculture technology was improved to a "carp-SIS polyculture" technology suitable for small scale farmers in Terai, Nepal. In December 2008, the project was initiated to improve income and nutrition of Tharu women in Chitwan (100 farmers) and Kailali (26 farmers) districts. The present paper presents the final results of the project.

Aquaculture, employment, poverty, food security and well-being in Bangladesh: A comparative study

This study addresses five research questions about the nature of aquaculture development in Bangladesh. The questions are designed to test central narratives from the literature on aquaculture, poverty and food security, and to broaden the scope of debate beyond them An integrated quantitative-qualitative survey was conducted in six communities with contrasting patterns of aquaculture development.

Pond polyculture technologies combat micronutrient deficiencies and increase household income in Bangladesh

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.

Multivariate models of tilapia and carp growth as an application of microcomputers in aquaculture research

An examination is made of the applications of microcomputers to aquaculture research, considering in particular data storage and processing and also statistical analysis programmes. Reference is made to development projects with the aim of making use of modern, applied research methods to develop aquaculture technologies applicable for developing countries.
