RESEARCH METHODS TO ASSESS THE IMPACT OF CLIMATE CHANGE ON FISHERIES
Some of the fisheries resources that may be most affected by climate change include fisheries stocks that are currently heavily or over-exploited, and species with narrowly defined physiological tolerances to environmental conditions such as high water temperatures or low levels of dissolved oxygen. This paper deals with research methods to assess the impact of climate change on fisheries. It outlines the Potential Climate Change Impacts on Fisheries Resources. This paper makes a comprehensive discussion on empirical modeling with respect to effects of precipitation changes on fish yields, effects of precipitation changes on catch on riverine systems, effects of temperature changes on fish yield, effects of precipitation changes on yield in marine systems, effects of temperature changes on yield in marine systems, effects of precipitation changes on habitat availability, effects of sea level rise on habitat availability, effects of temperature on habitat suitability, effects of multiple stressors on habitat suitability, evaluating physiological and life history constraints on growth and reproduction, effects of temperature changes on mortality, effects of temperature change on growth using bioenergetics modeling and effects of temperature change on physiological processes. This paper makes a specific discussion on application of historical analogy, socio-economic considerations, autonomous adaptation and planned adaptation towards identifying the impact of climate change on fisheries sector. This paper concludes with some interesting findings along with policy suggestions.
