Yeah Science can take over the natures impact thus subsidising the endangered or critically endagered population. But how long will people will catch the breeders and small sized fishes (which every government announce every fisherman). Even they have a particular breeding season when these people can avoid fishing or just catch and release the fishes if they feel they are of breeding size or even smaller size not fit for consuming. HUmans has that all in their hands of ravaging the nature sourrounding them
