Size-adjusted means (±1 SE) for (A) fecundity, (B) egg volume, (C) clutch volume, and (D) ovary weight for mature (Stage IV–VI) female Rastrineobola argentea from the Napoleon Gulf of Lake Victoria. These are adjusted means from an ancova model examining variation in each trait as a function of log(somatic weight) and year. The colours indicate the following time periods: pre-Nile perch boom/pre-commercial fishing (white), post-Nile perch boom/pre-commercial fishing (grey), and post-Nile perch boom/postcommercial fishing (black). The * indicate significantly different pairs based on post-hoc Tukey’s tests.
