   V návaznosti na ostatní limnologické a hydrobiologické přednášky se tento předmět bude
zabývat rolí vodních obratlovců ve vodním systému.Z tohoto hlediska budou probírány všechny
tradiční discipliny ekologie ryb, jakožto nejdůležitější skupiny vodních obratlovců v našich pod-
mínkách: adaptace na vodní prostředí, reprodukce, potrava, chování, populační dynamika atd.
Ostatním vodním obratlovcům bude věnováno místo podle jejich významu pro naše posluchače.
