Abstract

After being released into the aquatic environment, fish sperm have a limited time to reach the egg, two limiting factors for successful fertilization are the time it takes for the sperm to reach the egg and the other limiting time for the micropile hole to close. Sperm quality is one of the important factors in reproduction, which itself is influenced by various parameters such as motility time, sperm rate, osmolarity, sperm concentration in semen and ATP. In addition, nutritional parameters such as vitamins, minerals and fatty acids are involved in increasing sperm quality. It is very important to study the parameters and factors affecting sperm quality, because reproduction and reproduction of fish is one of the important production links in aquaculture. Also, studies on marine fish are much less than freshwater fish, and research in this area is needed for sustainable aquaculture.
