Broodstock, or broodfish, are a group of mature individuals used in aquaculture for breeding purposes. Broodstock can be a population of animals maintained in captivity as a source of replacement for, or enhancement of, seed and fry numbers. [1]
Broodstock Selection and Management The key to good hatchery management is obtaining and maintaining good quality broodstock. The best quality broodstock can be found in any Research and Development Institutions most especially at the National Freshwater Fisheries Technology Center. Maintaining good quality breeders denotes:
Oct 1, 2014 · The aim of broodstock management and breeding plans for hatcheries supplying fish for culture-based fisheries (CBF) is to consistently provide good quality (fit and healthy) juveniles suitable...
Broodstock are generally discarded when they reach 10 kg or when the relative productivity (number of viable eggs produced) is less than 5 % of the female weight. Hatcheries normally recruit new broodstock on a regular basis of every two to three years; new broodstock are obtained both from grow-out farms and the wild.
the broodstock, method of propagation, avail ability of appropriate food and environmental conditions. As an integral part of hatchery tech niques, broodstock management will determine the quality of resulting fry and fingerlings. Selecting broodstock: • free from any physical deformities • well developed sex organs • high fecundity ...
