Role of Broodstock Nutrition and its Impacts on Fish Reproductive Output: An Overview

Abstract

A major prerequisite for the successful growth of aquaculture is the ability to properly manage sexual maturation and spawning, as well as the production of huge numbers of high-quality seeds. One of the most critical variables impacting a cultured organism’s ability to reach its genetic potential for growth and reproduction is proper nutrition. Broodstock diet has long been known to affect fecundity, fertilisation rate, egg quality, embryo development and larval quality, as well as hatchery success. Optimal broodstock management strategies based on a thorough understanding of the nutritional and environmental needs of fishes bred in captivity. Many factors influence fish growth, gonad development and reproduction. Protein, lipids, minerals, vitamins and carotenoids are among these factors. Not only has improved broodstock nutrition and feeding been demonstrated to improve egg and sperm quality, but it has also been shown to improve seed yield. As a result, over the last two decades, increased emphasis has been placed on the levels of various nutrients in broodstock diets. Broodstock nutrition research, on the other hand, is scarce and relatively expensive to do.
