Seed Production of Grass Carp and Silver Carp: Use of Various Management Techniques in Seed Production of Grass Carp and Silver Carp

The increase in seed production is a key factor in increasing world fish production , since seed production has been used not only to supply fish culturists but to supply natural waters too. This study is a baseline comprehensive one, focusing on the management measures usually undertaken during the seed production operation, since the reliable supply of good quality of eggs and fry (often collectively known as seed) is considered a backbone for a successful aquaculture industry. However meaningful conclusions and practical solutions have been behind the emphasis to conduct this study under normal field conditions, despite the well known difficulties and adverse risks associated with such studies. The purpose of this study is to increase grass and silver carp seed production through evaluating different management measures that were used in egg and fry production, and ways of improving such measures with emphasis on water quality, pond fertilization, stocking densities and predator control.
