Research Abstract

The occurrence of temperature-dependent sex determination in Hypoatherina tsurugae was examined as a first step to develop an indicator species for assessing the impact of global warming on sex determination of marine teleost fish. Wild H. tsurugae young-of-the-year were collected by fishing net and ascribed into two hatching date groups (spring- or summer-hatched) as inferred from the number of daily rings in their otoliths. Male/female sex ratios of each group were then calculated. The sex ratio of the spring-hatched group was approximately 1:1 while that in the summer-hatched group was highly male-biased. The average water temperature at hatching for the spring- and summer-hatched groups was 20.2C and 23.9C, respectively. Laboratory rearing of larvae at two temperatures during the supposed period of gonadal sex differentiation confirmed the formation of more males at high temperature. These data suggest that the sexual fate of H. tsurugae can be affected by elevated temperature.
