The effects of water depth and light on oviposition and egg cannibalism in the bluefin killifish Lucania goodei

Research output: Contribution to journal › Article › peer-review

Abstract

This study showed that sex and depth had strong effects on egg cannibalism, whereas water clarity (clear v. tea-stained) had no effect on cannibalism or oviposition in the bluefin killifish Lucania goodei. These results are consistent with the extreme levels of iteroparity in L. goodei where females appear to spread their eggs across multiple locations and depths presumably to avoid egg predation.
