Innovative directions of the biotechnology of growing Cherax quadricarinatus in the aquaculture of Ukraine

Abstract

In the conditions of the modern development of the world fishery, the production of hydrobionts shows a steady tendency to decrease in volume, which determines the prospects of breeding hydrobionts, including crustaceans, in artificial conditions. The great demand on the world market for edible species of crustaceans, as well as the deterioration of the ecological conditions of water bodies, led to a decrease in their natural reserves. Aquaculture of crustaceans is a relatively new direction, which has good prospects both from the ecological and food points of view, including in our country. Crustaceans are a valuable source of protein. For the maximum effect of growing tropical species of crayfish, namely – Cherax quadricarinatus, it is necessary to know the peculiarities of morphology, critical periods of ontogenesis, peculiarities of cultivation. Studying the best practices for growing decapod crayfish will contribute to the development of technological schemes for growing introduced species in artificial conditions for the maximum resource-saving effect. In the case of crayfish cultivation using industrial aquaculture methods, it is necessary to reduce the use of clean water as much as possible, to obtain ecologically clean products in the shortest possible time.
