Summary Samples of 0‐group snapper Chrysophrys auratus were collected in the Hauraki Gulf of New Zealand in 1979,1980 and 1981. Each fish was measured and the liver examined for an esterase polymorphism. A similar change in allele frequency with length was observed in each year class. In the total data set there is a significant relationship between allele frequency and length. The relationships between allele frequencies and temperature and growth, along with implications for genetic‐stock separation studies are discussed.
