Brown Trout Ecology in the Rio Grande, Argentina

The Rio Grande brown trout study objective was to determine population parameters and factors controlling productivity of sea trout (sea-run brown trout) in the Rio Grande of Tierra del Fuego, Argentina. FLBS used the catch and release fly fishing operations of NWA and EMB as a basis for a mark and recapture study of the brown trout population within various study reaches of the river in association with other ecological measures encompassing the freshwater life cycle.

The project goal was to use the accumulated information as a basis for development of a strategy to sustain high-quality angling and ecotourism income in the Rio Grande and to use scientific results to better inform salmon and trout management worldwide.
