The issue of climate change has generated a lot of concern among the general public in Niger Delta region in recent time. It has been described in different ways by many people based on their views, perception and understanding. However, little considerations have been given to the impact of climate change on brackish water aquaculture in the coastal areas of Niger Delta. This study therefore, review critically, based on existing literature and field experience, the causes of climate change, impact of climate change on aquaculture production such as: increase in temperature, flooding of ponds, increase in water turbidity, heavy siltation of pond bottom, introduction of new species, collapse of farms infrastructure and fluctuations in salinity levels. Also, various adaptation and mitigation strategies that will ameliorate the impact of climate change in aquaculture operations, namely: reduction in human activities that are inimical to stable climate, selection of good site suitable for fish farming, provision of shading materials for fish cultured in tanks, raising of pond dykes, good management practices and improvement of monitoring and early warning systems are explicitly elucidated. As these strategies will go a long way in minimizing the impact of this menace, in the brackish water zone of the region. Moreover, efforts should be made by relevant institutions and agencies to come up with coordinated plans and policies that will reduce the effects of climate change on brackish water aquaculture in the coastal areas of Niger Delta. © 2015 Academic Journals Inc.
