New study on migratory fish and bird predation
Posted on March 11, 2013
A recent study has found that migratory fish are less susceptible to predation by piscivorous birds like cormorants. The study involved partially migratory populations of roach and suggests that winter migrations from still waters to rivers and streams make roach safer from predation. This adds weight to the arguments that good quality habitat and connectivity are vital for healthy fish populations. For WTT advice on habitat restoration and connectivity measures, click here.
