fishery-independent surveys

Fishery-independent surveys are scientific methods used to assess fish populations directly, without relying on commercial catch data. Researchers use specialized equipment like trawl nets, underwater cameras, or sonar to sample fish in their natural habitats. These surveys provide unbiased estimates of fish abundance, distribution, and health, helping scientists manage and conserve fish stocks sustainably. They are essential for understanding the true status of fish populations, independent of fishing effort or market influences.
