Owing to established impacts of mass migration, habitat loss and deforestation on biodiversity, it is imperative to investigate the global warming on aquaculture welfare and productivity. Our current understandings on impacts of altered climate dictate a weak relationship between global warming and naturally occurring migrations. However, several models have been presented that elucidate the negative impact of global warming on the aquatic biodiversity. While impact of global warming on habitat is imperative, additional factors such as predation, food shortage or heavy fishing may exacerbate the climatic impacts on the aquaculture biodiversity. Based upon current general consensus among researchers, a global legislation and action-plan is required. Additionally, regulatory authorities from both developed and underdeveloped countries should enforce the implementation of these legislations. Such initiatives are fundamental in conservation of aquaculture, sustainability of increasing food security and to maintain the ecosystem of the planet.
