Efforts to boost fish populations by allowing fisherman to catch only larger fish could be doing more harm than good, according to a recent study. Australian researchers say that, as a result of fishing bans and quotas, the slower-growing, more timid fish tend to be left behind to breed and pass on their genes. And they believe this explains why fish populations do not recover as expected after bans or quotas are put in place.
