Fewer fish eggs, smaller fish result from over-fishing

A recent study by UC Riverside graduate student Matthew Walsh found that harvesting large individuals from a fish population introduces genetic changes that harm the overall fish population. The remaining fish become progressively smaller, have fewer and smaller eggs with lower survival rates, and lower foraging and feeding capabilities.
