STANDARD EXCHANGE OF LARVAES OF THE CHANNEL CATFISH ICTALURUS PUNCTATUS (RAF. 1818)

The experimental data on the study of level of standard exchange of the larvaes of channel catfish are resulted. It was determined on speed of consumption by them the oxygen in time unit. It is set, that a standard exchange of larvaes of channel catfish correlates with their mass and is expressed by equalization: Q=0,635W0,80 (mgO2/ekz/hour). Set to dependence can be used both for the decision of power expenses on exchange processes of larvaes of channel catfish, and for the determination of their food necessities.
