The Asian countries, in particular Bangladesh, China, India, Indonesia, Thailand and Vietnam, have vast carp genetic resources that are an important element of their aquaculture production systems. Hence, in recent years, the governments of these countries have been recognizing the need to exercise a precautionary approach in the introduction of any aquatic organism, including carps. Information on the introduced species is a prerequisite for implementing programs aimed at Chapter 6 The Status Of Introduced Carp Species In Asia1 Belen O. Acosta2 and Modadugu V.
Local production of mixed sex Nile tilapia in irrigated rice fields has been introduced, established and then spread through farmer-to farmer contact in Northwest Bangladesh benefiting poor households in a number of ways. Food fish farmers have improved access to high quality seed at the time of peak demand early in the monsoon season. The seed producers benefit through small but strategic cash flows but also improved production of their fish for their own consumption, both as large fingerlings and fish after further grow on.
Experts carried out selective breeding of Rohu carp for greater harvest weight and yielded an average of 17% genetic gain per generation in 5 generations of selection.
There are over 1 300 species of cyprinids in Asia, which form an important part of the world’s aquatic biodiversity. Aquaculture and capture fisheries involving cyprinids are a vital part of the livelihoods of many millions of people in this region. The production of carps from aquaculture in Asia constitutes over half of world finfish aquaculture production. Further growth in human populations will increase the demand for carps as food, but may also threaten wild populations.
In India, inland aquaculture has emerged as a fast-growing enterprise and a viable alternative to the declining capture fisheries. The present paper is an attempt to assess Indian inland aquaculture with respect to its resource base, output trends, systems and activities, yield gaps, adoption and impact on aquaculturists, economics, returns to inputs, investment needs, and future prospects. The paper is largely based on existing literature and observations made as part of an ICAR-WorldFish demand supply project.
This major work on carp hatchery and nursery methods was part of an Asian Development Bank (ADB) project to improve carp seed production technology in ADB-member countries notably Bangladesh, Burma, Indonesia, Nepal, Pakistan and Sri Lanka. Designed as a reference source on carp seed production and as a mini-library for those stationed at seed production centers remote from scientific information channels.
With financial support from Asian Development Bank, a carp genetic research project initiative was set up in 1995 assist the six major carp producing countries (Bangladesh, People's Republic of China, India, Indonesia, Thailand and Vietnam) to increase food fish production and to improve the nutrition and income of small-scale fish farmers by developing genetically improved carp breeds with sustainable productivity.
An illustrated manual in comics format on how to culture the common carp in floating cages. The techniques described were actually developed in the common carp culture in Bandung, Indonesia, and can be easily adapted to other sites.
This book contains six chapters 1)Introduction 2) Status of carp genetic resources 3)Brood stock management and artificial breeding of carp species in hatcheries 4)A breeding plan for cultured minor carp species 5)A breeding plan for cultured major carp species 6)Breeding and conservation of endangered carp species
Participatory research was conducted with poorer farmers in two communities, Girai (G) and Bahagili (B) in NW Bangladesh to assess the production of Nile tilapia seed in irrigated spring rice-fields. All the selected households (G=15; B=4) had previous experience producing common carp (Cyprinus carpio) in the rice-fields allocated a separate plot in which a deeper area had been excavated for this trial.
