A simple immunotest for monitoring the egg maturation in rainbow trout (Oncorhynchus mykiss).

Abstract

On the principle of the single-radial-immunodiffusion a method has been developed to estimate serum vitellogenin quantitatively in maturing rainbow trouts. Serum vitellogenin (VG) content correlates with the egg diameters. Thus it is possible both to establish the beginning of the egg maturation and to monitor it in a simple way.
