These guidelines are intended to assist fishermen with the rigging and use of square-mesh panels in compliance with current fisheries regulations (Square-Mesh Panel Council Reg. (EC) No 850/98. The Sea Fish (Specified Sea Areas) (Regulation of Nets and Other Fishing Gear) (Scotland) Order 2000 No.227)and The Sea Fish (Specified Sea Areas) (Regulation of Nets and Other Fishing Gear) Order 2001 No.649).
Fish freshness is typically determined by sensory assessment, which relies on the use of trained assessors. Commonly used schemes include Torry and the Quality Index Method (QIM). The use of non-trained assessors, which is a common occurrence, can lead to highly variable results. As such it is desirable to find an alternative, instrumental method to provide an objective system for determining fish freshness. Ideally any such method should be reliable, rapid, non-destructive and easy to use. A wide number of instrumental techniques have been tested yet few have made it to commercial reality. In this study, several different methods have been used to evaluate cod over time, to assess which has the greatest potential in fish freshness assessment. These included spectroscopy and colour imaging measurement. Campden BRI was funded by Seafish to evaluate the potential of near infra-red spectroscopy and colour measurements as reliable methods of determining fish freshness. NIR measurements were made with a hyperspectral imaging system, and with a conventional bulk system. Colour measurements were made with a calibrated colour imaging system. This factsheet summarises the results.
This report describes fishing trials undertaken by commercial Shell fishermen based in the SW of England overseen by a Seafish employee based in Newlyn, Cornwall. This project arose from another Seafish trial, based in the West of Scotland looking at investigation the potential for targeting Deep Sea Red Crab (Chaceon affinis). The pots used in this project were originally used as part of the Red Crab project though had subsequently become surplus to requirements. The pots were thought to have potential in the SW spider Crab fishery as a possible alternative to the use of tangle nets. 90 pots were allocated during April/May 2006 to 10 fishermen working from 6 different ports around the SW coast, both on the North and South coasts. All the pots were rigged with a 14” cone entrance and a netted bottom as originally supplied by the manufacturer. The fishermen were also supplied with a logsheet to record catches in order to assess the effectiveness of these pots compared with a standard Inkwell or parlour pot. . On first inspection, fishermen were generally happy with the overall design of the pots, though the pots produced mixed results. The tendency being that they did not fish as well as standard inkwell pots fitted with 10” buckets. There were a number of reasons why the fishermen thought that these pots were not catching effectively, in the main it was thought that the Spider Crabs could too easily escape from the pots especially when the pots were not lying flat on the bottom due to insufficient weight in the base of the pot. The fishermen were invited to retain the pots and make any alterations they saw fit during the winter months to improve the pots performance.
LABORATORY LEAFLET NO. 48 - LOWESTOFT Worldwide interest in squid fisheries remained at a low level until shortly after the second world war when the Japanese developed their fishery for Todarodes pacificus into a major industry. In 1960 this produced a peak catch in excess of 690,000 tonnes. Subsequently the Japanese have exploited squid in several other parts of the world and over the last two decades a major fishery has developed in the North-west Atlantic involving distant-water fleets from most of the major fishing nations. This report has been produced from a scanned original and may therefore contain some formatting and other inaccuracies. In cases where this affects the technical content, a paper copy of the original report can still be obtained from Seafish.
Appraisal of the opportunity for offshore aquaculture in UK waters. Report of project FC0934, commissioned by Defra and Seafish from FRM Ltd.The report provides an assessment of the potential for open ocean, offshore finfish aquaculture in UK waters using candidate species which would have similar growth and performance characteristics to Atlantic salmon (Salmo salar) and Atlantic cod (Gadus morhua)and with due reference to other potential species candidates.
During the past decade, total squid landings from the NE Atlantic ranged from 10,000– 18,000 t. The bulk of European catches were landed by French, Portuguese, Spanish and UK fleets. Loligo forbesi is the most frequently caught species in UK waters, and forms the basis of significant by-catch fisheries, with annual landings as high as 3,500 t. A significant proportion (5–70%) of the total Scottish squid landings are caught in the Moray Firth, where a seasonal, directed fishery operates during summer-autumn. The size of the fleet directly involved in this fishery has ranged from 20–65 vessels in recent years. Many of the fishing crews target squid for several weeks, when large numbers of small squid recruit to the fishery.

Presented at Pelagic Industry Issues Group meeting. 5 October 2020.
This literature review looks at the role of a fishery observer and the rules governing fisheries observer programmes; the issues being raised; the most recent prominent cases; the repeated calls for reform; and the current situation in 2020 and the impact of COVID-19.

The effects of square mesh panel mesh size and position on the selectivity of high and low powered Nephrops trawlersAssessing the differences in performance between square mesh panels (SMPs) placed in the straight extension or in the taper, between 110 and 120 mm SMPs, and between gears towed by vessels of different horsepower.
