the juvenile fish will escape through the openings between the metal bars of the grid, while larger fish will be retained.

However, these gears are commonly used in specific seasons or at specific grounds where the fishers, by experience, are able to catch only one or a few species, so that the catches are usually dominated by a few targeted species. Information on by-mortality of fish after escapement from gillnets is scarce. Shrimp trawl with sorting grid (expanded view).
