Ecological Characteristics of the Far Eastern Fish Red-finned Mullet (Mugil so-iuy Basilewsky) Acclimated in the Sea of Azov

摘要

Here we summarize the results of long-term studies on the biology of the red-finned mullet (Mugil so-iuy Basilewsky) performed in order to fill the gap on our knowledge on one of the bast acclimated species introduced to the Sea of Azov. The new conditions appeared to be favorable for the red-finned mullet: the rates of linear-size and weight growth and early sexual maturation became high; physiological parameters, fertility, and the survival rates of eggs and larva in brackish water changed substantially [1-3]. This allowed the population to grow rapidly and ensured the stabilization of optimal values of biological parameters.
