fishery-dependent surveys

Fishery-dependent surveys are methods that collect data directly from fishing activities, such as catch records, fishing logs, and onboard observations. These surveys provide insight into fish populations, their distribution, and health by analyzing actual catches made by fishermen. Since they rely on real fishing operations, they reflect how fish are being exploited in the wild. This information helps scientists and managers make informed decisions about sustainable fishing practices, resource management, and conservation efforts. However, because they are linked to fishing activity, they can be influenced by fishermen's behavior and market demands.
