This project aims to provide a method to coastal fishers wishing to augment their crustacean catches with high-value, low-impact scallops.
The results arising from the “Scallop potting” Feasibility Study (FS059) described, for the first time, that scallops can be attracted into static fishing gear using LED lights. A global first. This novel finding presents a real and exciting opportunity for the development of a new, low impact method for harvesting scallops.
This programme of work looks to build on the findings and challenges described from the outputs of the feasibility study with the aim of 1) optimising the trap design so that it will harvest scallops effectively without impacting crustacean retention; 2) developing and manufacturing a new, low-cost light, specific to the operational needs of crustacean fishers. Further sea-trials will be conducted with the new traps and lights in different areas of high-density scallops (Lyme Bay and Dartmouth) and will look at crucial factors not tested in the Feasibility Study such as fishing region, light intensity, light colour, duty cycle and trap efficiency.
At the end of this programme of work (December 2022), we expect to have 1) optimised the trap design; 2) optimised the light used; and 3) optimised the harvesting method. With this information we aim to provide a method to coastal fishers wishing to augment their crustacean catches with high-value scallops.
