Chilean scientific vessels

May 13th, 2021 Mario Loyola

These vessels have specialized equipment and laboratories to estimate biomass ( fish abundance ) or fishery resources spatial distribution . In addition, and among other tasks, they monitor environmental and oceanographic conditions to predict and relate marine fauna behavior with environmental conditions.
How is fish biomass determined?
In scientific vessels there are sensors that emit sound waves that bounce off the shoals, producing a return echo, which allows the biomass to be investigated. This technique is known as hydroacoustic evaluation.
