Series: Fishing Industry %D 2013 %I %X Input characteristics of hydrobionts taking into account external abiotic and biotic factors are considered. The attention is paid, first of all, to input characteristics which are most important for research of the basic vital signs of animals in fisheries systems which it is possible or it is necessary to estimate quantitatively. The general features of output characteristics, such as number, structure, distribution in space and time, condition and behavior of biological system in a whole or its separate components are also considered. %K fisheries systems %K water organisms %K input and output characteristics. %U http://astu.org/content/userimages/vestnik/file/fish_2013_1/07.pdf
