Pollution is, undoubtedly, the most alarming issue of concern among all environmental hazards. The rate and degree of pollution is gradually increasing with the explosion in population of the world. Due to some anthropogenic activities and malpractices of some scientific methodologist gradual changes in climate turned the global situation
into a critical position affecting different aspects of agriculture, fisheries and others. Impact of climate change is conspicuously observing in the field of aquaculture posing adverse impact on its productivity and variety. Objective of the study was to prepare a review concerning about the impact of climate changes on fisheries and aquaculture sector. This review can be useful to find out a possible way for relieving the constrain through constructing some solution through various scientific activities. In present generation, the altered climatic condition shows a great impact on Ocean temperature, variation in water level, impact of sea level rise. For this climate change, there is a great impact on inland water. It is altering distribution and productivity of marine and freshwater species, and changing food webs. This making the concerns for viable of aquatic ecosystems for fisheries and aquaculture. Besides, it can also hamper our future scenarios. If these harmful effects are randomly proceeds, the future generation will also undergo a dangerous condition. Global warming is the main fact of these climate changes. Therefore, at first the main point is to reduce global emission of GHGs, which is the main anthropogenic factor. Fisheries and aquaculture
require specific adaptation and mitigation actions for responding to the chances for and threats to food and livelihood security due to climate change. The current generation need to decide, how should we get relief from these major problem of climate change and reduce the chances of future harm
