Inland aquaculture in India : past trend, present status and future prospects

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.

A hatchery manual for the common, Chinese and Indian major carps (2nd rev ed.).

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.

Management of broodstock and quality control of fish seed in Hungary

Common carp (Cyprinus carpio) breeding has a long tradition in Hungary. However, recent economic changes in Eastern Europe and new developments in aquaculture necessitated the need for ensuring quality of the brood stock used in hatcheries and the legal and institutional frameworks needed to implement the program. In addition to good research and development programs and gene banking, it became essential to establish an appropriate legal framework, organize, coordinate and control breeding activities, and provide financial support.

Socioeconomics and production efficiency of tilapia hatchery operations in the Philippines.

With the recent availability of genetically improved Nile tilapia strain in the Philippines, it is important to look at the existing profile of tilapia hatchery operations in the country to help examine the potential strategies in the dissemination of the improved strain among hatchery operators. This paper attempts to analyze the socioeconomics and production efficiency status of tilapia hatcheries in the Philippines prior to the adoption of genetically improved Nile tilapia strain.

Preliminary study of tilapia fry production in Kuwait 1983

The reproductive potential of three tilapias (Oreochromis aureus, O. spilurus and a red tilapia from Taiwan) were tested in 2 m3 fiberglass tanks with a water salinity of 3-5 ppt. Also, the hybridization of O. spilurus and O. aureus was attempted. The tests lasted for 192-207 days. Eggs were collected weekly and incubated artificially. The number of fry produced was noted. Results showed O. spilurus to have the highest reproductive potential based on fry production (75 fry/m2/day) adn the longest spawning season.

Fry production of Shire River tilapia Oreochromis shiranus at two broodstock sex ratios.

Optimal sex ratio in tilapia breeding ponds depends upon stocking density. However, under certain circumstances, altering the male: female sex ratio from a more or less natural 1:1 to 1:2 or even higher has been shown to increase fry production in oreochromiines. The research reported here was a first step toward establishing the broodfish sex ratio that Malawian smallholders ought to use to produce the maximum number of 0. shiranus fry under local conditions.
