The Effects of Salinity on the Growth and Survival of Marine Fish Larvae

Abstract

A rapidly growing industry, aquaculture contributes significantly to the supply of high-quality animal protein in both industrialized and developing nations. With significant development potential, it has become one of the most promising industries globally. By the turn of the century, it is anticipated to account for around 25% of the world's total fisheries. The central nervous system, endocrinological, and neuroendocrine systems are among the "internal factors" that regulate fish's continual development and growth. They are also among the vertebrates that rely heavily on their surroundings. Among other things, the effects of water saltiness on fish development and improvement have been the subject of various investigations. Saltiness is fundamental for most of species' egg treatment and brooding, yolk sac resorption, early embryogenesis, swim bladder development, and larval development. Saltiness has a significant impact on the distribution of species and the composition of aquatic animal communities. For example, even in species that can survive in a variety of salt levels, salinity can impact the development rates and metabolic expenses of both adults and juveniles. In addition to these physiological and metabolic impacts, salinity can have an impact on the advantages and disadvantages of parental behaviors. The impact of salinity on marine fish larvae's growth and survival are covered in this study
