Females of the stream goby Rhinogobius sp. DA with paternal care favor males courting in fast water currents, whereby they mate males of high parental ability. Here we examined female choice of male nest size of this goby in laboratory. The dichotomous choice experiment clearly indicated that females prefer large nests. Spawning at large nests seems to improve egg survival rates in natural habitats in this goby. We discuss the possibility of multiple criteria in mate choice of this goby.
具有亲代抚育行为的溪流虾虎鱼（Rhinogobius sp. DA）雌性偏爱在快速水流中求偶的雄性，从而与具有高亲代能力的雄性交配。在此，我们在实验室中研究了这种虾虎鱼雌性对雄性巢穴大小的选择。二分选择实验清楚地表明，雌性更喜欢大巢穴。在大巢穴中产卵似乎能提高这种虾虎鱼在自然栖息地中的卵存活率。我们讨论了这种虾虎鱼在配偶选择中存在多种标准的可能性。
