An account is given of the cage culture system used in sewage canals in Indonesia. The fish cages used at Kota Cianjur for the culture of Cyprinus carpio are described.
An experiment was carried out to investigate the influence of music on the growth of Koi Carp (Cyprinus carpio) by subjecting the fish to music. Weekly growth in weight was recorded and used to calculate the growth rate and specific growth rate. The difference in growth between the control and experiment groups of fishes was statistically tested for significance. It was observed that the growth of fish subjected to music was significantly higher.
This chapter focuses on the status and future of carp production in Bangladesh, China, India, Indonesia, Thailand and Vietnam. The analysis is largely based on primary data collected through surveys of 2 025 carp fish farmers conducted during 1998-99. In addition to the primary data, databases compiled by the Food and Agriculture Organization of the United Nations (FAO) and unpublished reports from Asian countries were also used.
Fish is the main animal protein source for the people of Bangladesh. In spite of vast water resources, fish production is in decline, resulting in protein-energy malnutrition. Farmers participating in on-farm research developed low-input sustainable aquaculture practices that benefit the poor farmers, who constitute the bulk of the population. Farmer-oriented studies have confirmed the viability of culturing silver barb (Puntius gonionotus) and nile tilapia (Oreochromis niloticus) in seasonal ponds. Productions of 1,2052,156 kg of P.
A summary report of the proceedings of the Asian regional conference on carp hatchery and nursery technology held in Manila, Philippines, on 1-3 February 1984, sponsored by the Asian Development Bank and ICLARM.
This document outlines the specifications of a project for carp and mullet hatcheries, nurseries and collecting stations in Egypt.
The impacts of sanctuary on fish production and fish biodiversity were investigated in Dopi beel in Joanshahi haor over a period of two years from January 2004 to December 2005. Broadly two different types of materials were used to set two sanctuaries in Dopi beel referred to as Treatment 1 and Treatment 2; the control treatment was set in another beel named Chotadigha-boradigha beel without using any materials. Data on fish production and species abundance obtained from different treatments were compared.
ADB RETA 5711 on the Genetic Improvement of Carp Species in Asia showed that the growth performance of carps, the most cultured fish in the world, could be improved by 10% per generation of selection, based on the preliminary studies of 4 carp species in the 6 Developing Member Countries (DMCs) participating (Bangladesh, the People's Republic of China, India, Indonesia, Thailand and Vietnam).
The availability and quality of fingerlings for stocking in aquaculture ponds have repeatedly been identified as a key constraint to the development of aquaculture in Africa. Government hatcheries have generally failed to achieve sustainability and the private sector is impeded by the lack of marketing information and appropriate technological assistance. At present, the main aquaculture species in the continent are Nile tilapia (Oreochromis niloticus) and the African sharptooth catfish (Clarias gariepinus).
An experiment to rear carp seed was conducted in Tamil Nadu, India during October 2001 to April 2002 as a part of an ambitious programme aimed at standardization of pen fish rearing technology for production of stocking material of desired size at a lower cost. The experiment used six pens erected using locally available materials in the exposed marginal area of an existing reservoir.
