Abstract

A method to determine the sex of adult galjoen by biochemical analysis of a blood sample is described. The test measures the amount of yolk protein (vitellogenin) present by determining the levels of alkali-labile protein-linked phosphorus in the blood plasma. Vitellogenic females show values averaging 20 μg protein phosphorus per ml plasma, whilst males and non-vitellogenic females show levels normally less than 1 μg and not exceeding 5 μg/ml. This method allows most females to be positively identified several months prior to, and during, the spawning season.
