Method:

Although the 4.9 m trawl is the primary gear used in this sampling programme, alternative gears such as this one are sometimes used when the large trawl is unfeasible.

A 30.5 x 1.8 m small-mesh beach seine (1.3 cm mesh) is an alternative gear used with shallow even bottoms - generally near small river mouths, where trawling is not feasible. The seine is pulled through the water in an arch to capture shore-dwelling fishes. Effort is measured in seine hauls and would consist of two hauls per sampling location.
