The role of social learning in conservation and fisheries reintroductions
The plight of the world fish stocks is all too well documented. As part of an ongoing attempt to bolster fish stocks for both commercial and conservation purposes, many fish are reared in captivity and released into the wild. It is well known that hatchery‐reared fish have low post‐release survival...
