Abstract
The migratory behavior and spawning of Curimatá-pacu (Prochilodus argenteus) were assessed in a free-flowing remnant spanning approximately 450 km. This evaluation was conducted using radio-tagging and egg sampling, with identification performed through metabarcoding techniques. Among the studied individuals, half migrated 100–365 km upstream, primarily in response to the initial rise in river discharge at the onset of the wet season. Conversely, the remaining fish did not exhibit upstream movement, indicating a partial migratory behavior. The presence of eggs exclusively in the headwaters suggests that breeding occurred solely among fish inhabiting the upstream sites. The observed migratory traits resembled those of other congeneric species.
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.
