|The trawls used to sample demersal fish are normally slightly modified commercial fish or shrimp trawls. Such trawls are designed to capture commercial species, and do not lend themselves well to representative sampling, mainly due to the herding effect of trawl doors, sweeps and bridles. The impact of herding is different on different species and size groups of the same species, and both inter- and intra-specific effects can be quite large. The SURVEYTRAWL project intends to provide the strategic basis and initial design for a new survey trawl, which will represent a good compromise in terms of being non-herding and non-selective, and with stable and consistent operation. The final objective is to produce a new trawl with the characteristics of a beam...
