Australian research finds global fish stock assessments overly optimistic, leading to inadequate catch limits and exacerbating overfishing problems.
New research from Australia reveals that global fish stock assessments have often been overly optimistic, leading to inadequate catch limits and exacerbating overfishing problems. The study, which analyzed data from 230 fish stocks worldwide, found that stock assessments have often overestimated fish abundance and recovery rates, resulting in "phantom recoveries" where stocks were incorrectly classified as recovered while continuing to decline. The researchers call for more realistic stock assessment models based on ecological principles and a greater application of the precautionary principle, suggesting that conservative estimates should be used to protect stocks, and advocate for sustainable fishing practices.
