The representatives of Pisces family, namely Gobidae are an important component of aquatic ecosystems. With a wide range of adaptation, this group has mastered the different types of fish ponds from completely fresh to the ocean. However, some species are found both in one and in other waters, displaying different (and sometimes conflicting) between a life strategy. Last relating to the four main components of the life of fish: water-salt metabolism, nutrition, respiration and reproduction. Mechanisms for implementing these different functions together. First, different concentrations of salts require different types of water- salt metabolism. Another equally important factor is the food base, which is also quite different, both in range and the nature of food. In the sea and reservoirs, over rivers, dissolved oxygen in the water is stratified, and very often in the summer and winter time is in short supply.
