Testing Materials used in Queen Scallop dredge Construction_IPF C100

Summary

The work aims to improve the durability, reduce the weight and environmental effects and minimize costs of Queen Scallop dredges by finding more durable and or cheaper materials for use in dredge component construction.Gear developments tested have included the use of rollers, skids and flexible rubber flappers to replace steel teeth normally used. This has been observed to reduce King Scallop (pecten maximus) by catch and stone retention in the dredges and also greatly reduces seabed impact compared with standard tooth dredges. This report to be read in conjunction with SR613 Analysis and suggested modifications for Queen Scallop dredge net_IPF C100
