Simple technology changed fish hatchery production scenario in Bangladesh

Most of the fish hatcheries of Bangladesh are situated at Jessore district. Oxygen concentration in the water of these hatcheries is very low and carbon dioxide level is higher than desired.

Algal bioproducts derived from suspended solids in intensive land-based aquaculture

Land-based aquaculture produces suspended solids in culture pond and settlement pond waters that could be harvested as a bioresource. The first aim of this study is to quantify, characterise, and subsequently harvest the suspended solids from two discharge waste streams in pond-based intensive aquaculture.

Inbreeding and effective population size in a coho salmon (Oncorhynchus kisutch) breeding nucleus in Chile

A commercial breeding nucleus of coho salmon (Oncorhynchus kisutch) was established in Chile in 1997. This nucleus consists of two independent populations corresponding to different year-classes (even and odd, depending on the spawning year), which have been successfully selected for harvest weight (approximate genetic gain per generation of 10%).

Optimizing benefits from the Egyptian farmed fish value chain

Egyptian aquaculture is booming, yet greater fish quality and effective industry support are still needed. A value chain approach is helping research and development partners overcome barriers to sustainable growth.

Shahnaz is a role model for rural women in fish culture

Shahnaz Dewan, a former elected member of local government, lives in Adabari village in Tangail District, Bangladesh. While Shanaz was engaged in household activity and social work, her husband used traditional methods of raising Indian Major Carp in his pond and she had very little involvement in fish culture.

Strain comparisons in aquaculture species: a manual

When different strains or breeds of a particular species are available, the best choice is seldom immediately obvious for producers. Scientists are also interested in the relative performance of different strains because it provides a basis for recommendations to producers and it often stimulates the conduct of work aimed at unraveling the underlying biological mechanisms involved in the expression of such differences.
