Population Parameters and Stock Assessment of Mylossoma albiscopum (Characiformes: Serrasalmidae) in the Amazonian Plain of the Putumayo River, Colombia
Mylossoma albiscopum is one of the primary species consumed by humans in the Colombian Amazon, but understanding is limited on its life history traits and the current status. Therefore, the fishery was monitored in the Putumayo River basin between 2016 and 2023 to estimate growth parameters and assess stock status using the data-limited LB-SPR method. Asymptotic length (L∞) was 28.63 cm, natural mortality (M) was 0.92, von Bertalanffy growth (k) was 0.39, and length at 50% maturity (Lm50) was 15.0 cm. The spawning potential ratio (0.39) was similar to the reference point (0.40), so the fishery exploited the population near its optimal level. We recommend that the Colombian fisheries authority consider Lm50 as the legal catch length limit and continue annual evaluations of the fishery to ensure its sustainability.
期刊介绍:
Fisheries Management and Ecology is a journal with an international perspective. It presents papers that cover all aspects of the management, ecology and conservation of inland, estuarine and coastal fisheries.
The Journal aims to:
foster an understanding of the maintenance, development and management of the conditions under which fish populations and communities thrive, and how they and their habitat can be conserved and enhanced;
promote a thorough understanding of the dual nature of fisheries as valuable resources exploited for food, recreational and commercial purposes and as pivotal indicators of aquatic habitat quality and conservation status;
help fisheries managers focus upon policy, management, operational, conservation and ecological issues;
assist fisheries ecologists become more aware of the needs of managers for information, techniques, tools and concepts;
integrate ecological studies with all aspects of management;
ensure that the conservation of fisheries and their environments is a recurring theme in fisheries and aquatic management.
