Some data on the basic metabolism of trout eggs

Abstract

Oxygen consumption was found to be essentially the same in unfertilized trout eggs, water activated eggs and eggs immediately after fertilization. Trout eggs are capable of regulating the pH of the surrounding medium probably by releasing buffering electrolytes. The electrolyte composition of the coelomic fluid is close to normal vertebrate blood serum. The coelomic fluid may permit further growth of ovulated eggs before spawning.
