They suggest a unified framework approach to forecasting the implications of climate changes for marine fish production which involves: (i) identifying relevant mechanisms, (ii) conducting a feasibility assessment of the implications of downscaling climate scenarios, (iii) evaluating climate model scenarios and selecting Intergovernmental Panel on Climate Change (IPCC) models, (iv) extracting environmental variables from climate scenarios and incorporating them into projection models, and (v) evaluating fish and shellfish production under a changing ecosystem. Recently, Zhang et al. ( According to the Food and Agriculture Organization’s (FAO) exploitation state summary of 441 assessed stocks, 77% were fully exploited or overfished, depleted or recovering (Kelleher, 2005).
