Metadata: Sustainable razor clam fishery 2013/14 - Fisheries Science Partnership
Abstract:
The fishing vessel Harmoni (MR7) was chartered to carry out experimental electro-fishing for razor clams. The aim of the survey was to establish whether a commercial fishery with this gear was viable commercially and environmentally sustainable. There was initially a period of gear design and construction which, together with some unavailability of either the vessel of Cefas staff, delayed the project until the winter of 2013/14. The weather was exceptionally poor and delayed the start of work such that funding had to be carried forward into the next financial year. Fieldwork commenced in May at a site off Southport, but despite the experimental gear deploying and working as envisaged, no razor clams were caught. It was decided that a new fishing area should be tried and at the suggestion of the skipper, a diving company was engaged to survey positions where catches had been made previously. One position was found to have a significant density of razor clams and this was chosen as a target for the next trip. Unfortunately this position was in too shallow water for Harmoni to reach and deploying the gear a short distance to seaward produced no catch. After further tows through the area which also proved barren, the project was abandoned.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Methods The gear The razor clams respond to electrical pulses by vacating their burrows allowing them to be collected by the cage. The aim was to optimise the towing speed, voltage, pulse frequency and the angle of the blade at the front of the collection cage both in terms of the catching efficiency of the gear for the target species and minimising environmental impact. A camera was to be deployed on the collection cage to monitor the action of the sledge on the seabed and observe the reaction of benthic organisms to the electric pulses. |
