Potential Application of Models in Forecasting the Effects of Climate Changes on Fisheries

Abstract
Increased concentrations of carbon dioxide and other “greenhouse gases” in the atmosphere and the possible resulting climatic changes will affect marine and freshwater fisheries. Many of the links in the causal chains relating these environmental changes to possible changes in fish stocks may be amenable to prediction through mathematical modeling. The adequacy of existing types of mathematical models relating changes in atmospheric CO2 to changes in environmental conditions and ultimately to changes in fish stocks is reviewed in the context of an overall strategy for forecasting changes in fish stocks. The model types include ecosystem models, fish physiological process models, and fish population models.
