Module 5: Sampling with Gear

Fishing gear is commonly utilized for catching fish in estuarine and coastal marine environments, serving both fishing and scientific research purposes. Using gear for sampling is a simple, quick, and cost-effective method to collect samples from a well-defined area, while also enabling the capture of live individual specimens. The specifications of these gears vary to align with different objectives and target species. Every fish sampling technique has some level of selectivity based on habitat, as well as the size, species, life stage, and body shape of the fish.
