fisheries assessment techniques

Fisheries assessment techniques involve methods to estimate fish populations and their health. Scientists often use surveys, like sampling fish with nets or traps to count and measure them. They also analyze data such as catch rates, age structures, and reproductive status. Tagging fish helps track movement and survival rates. Acoustic methods, like sonar, can detect fish schools underwater. Combining these approaches provides insights into population size, growth, and sustainability, helping to manage fishing activities responsibly and ensure fish populations remain healthy for the future.
