Evaluating methods for setting catch limits in data-limited fisheries

摘要: a b s t r c The majority of global fish stocks lack adequate data to evaluate stock status using conventional assessment methods. This poses challenge for the sustainable management these stocks. Recent requirements set scientifically based catch limits in several countries, and growing consumer demand sustainably managed have spurred an emerging field methods estimating overfishing thresholds setting with limited data. Using strategy evaluation framework we quantified performance number data-limited For most life-histories, found that made use only historical catches often performed worse than maintaining current fishing levels. Only those dynamically accounted changes abundance and/or depletion well at low sizes. Stock assessments make effort did not necessarily out-perform simpler fewer There is high value additional information regarding depletion, when are available. We discuss implications our results other identify future research priorities.
