摘要溪流虎鱼Rhinogobius sp.在父亲的照顾下，雄性在湍急的水流中求偶，从而与具有高亲子能力的雄性交配。在这里，我们在实验室里考察了雌性对这只虎虎鱼雄性巢大小的选择。二分选择实验表明，雌性更喜欢大巢。在大型巢中产卵似乎可以提高这种虎鱼在自然栖息地的卵存活率。我们讨论了在这种虎鱼的配偶选择中使用多种标准的可能性。
Abstract 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.
