- W2553242595 abstract "Summary. This developmental project involves design and test of a monkfish grid to reduce juvenile monkfish catch in the trawls targeting monkfish and other groundfish species in the Gulf of Maine. Excessive undersize monkfish catch and subsequent discard in trawls is contrary to the sustainable exploitation of the resource. A Nordmore grid-style device will be tested to exclude small monkfish passing through a 90 mm spacing grid. Successful result of use this or similar grid will lead to comprehensive test in trawls targeting for monkfish (the large mesh sector). The grid design utilizes information obtained from a previous research on grids for separating fish species and sizes. The preliminary grid will be 90 mm grid spacing and installed at 48 to 60 degrees. The alternating tow method will be used to evaluate the design in terms of juvenile monkfish reduction, retention of legal size monkfish and other commercial groundfish species, and operational aspects for handling the grid with existing deck equipment. However, sea trials have not yet carried out. Objectives and Statement of Research. The objective of the proposed research is to test a rigging design for the Nordmore grid to reduce fish bycatch. The proposed research will involve: ◆ Design and manufacture a grid suitable exclusion of undersized monkfish . ◆ Conducting full scale trials with the grid onboard a commercial trawler in Gulf of Maine; ◆ Conducting underwater video camera observation of the behavior of fish exiting the grid openings under fishing conditions; ◆ Evaluate the design or its modification for potential of more extensive sea and/or flume tank tests." @default.
