|Super shooter is primarly designed to exclude large animals from prawn trawls. It features an alluminium grid secured to the trawl at 45 degrees from the vertical.|
Bar spacing is typically 100 mm. A funnel of netting guides all animals to the top of the grid. Large animals are the guided by the grid towards the escape opening in the bottom of the codend while prawns and other small animals pass through the grid and enter the codend. A flap of buoyant netting over the escape opening prevents prawn loss. Prawn loss may be due to incorrect grid angle, grid blockage or poor guiding panel performance. High grid angles may increase the distance between the guiding panel and grid and allow prawns to escape. Increasing the length of the guiding panel or adding weights to the end of the panel may prevent prawn loss. Grid blockage by sponges, coral etc. may be caused by low grid angles or poor grid design. Increasing the size of the exit hole between panel and codend my reduce this problem.
