An endangered species is a taxonomic group (typically at the species level) that faces a very high risk of extinction in the near future across all or a significant portion of its range, as determined by quantitative assessment criteria such as population size, rate of decline, geographic range, and degree of habitat fragmentation. In conservation biology and environmental policy, endangered status guides prioritization of management actions, legal protections, and resource allocation. Scientific evaluation commonly uses standardized frameworks (e.g., formal Red List–type criteria) based on demographic trends, reproductive rates, and known or projected threats, including habitat loss, overexploitation, invasive species, pollution, and climate change.
More than 3,000 fish species have been caught in bottom trawls, with estimates suggesting the true number could be nearly double, according to the world's first global inventory.
