Trials to Compare the Thermal Performance of a New Design of Tri-pack Corrugated Plastic Non-reusable fish box with Expanded Polystyrene and Single Walled Fibreboard Boxes

Trials were carried out to compare the thermal properties of expanded polystyrene (EPS), single walled fibreboard (SWF) and corrugated plastic (CP) boxes. The boxes were tested in an environmental chamber and fish fillet temperature in each box was recorded for two time-temperature profiles. The first profile represented an interrupted chilled chain distribution over 66 hours, such as by airfreight, and the second profile represented a controlled chilled distribution of 72 hours, such as by road transport. Fillets in each box were chilled using a single frozen gel-ice pack placed on top of the fillets, or using ice. The EPS box was most effective at maintaining low fillet temperature for both temperature profiles and cooling methods. The CP box had similar but slightly better insulative properties than the SWF box. Ice chilling of fillets was more effective than a single gel-ice pack at maintaining low fillet temperatures for both temperature profiles. At the end of the trials using ice, the amount of melt water produced exceeded the capacity of the absorbent pad used. The ratio of ice used and/or absorbent pad capacity needs careful consideration to prevent fillets from soaking in melt water in non-draining boxes. Where fish is distributed in an uncontrolled chilled distribution chain, boxes with greater insulative properties, such as EPS would be advisable in order to maintain low product temperatures. Where fish is distributed in a strictly controlled distribution chain, it would be beneficial to use boxes with less insulation, to allow chill temperatures to influence product temperatures.

Seafish Summary of agreed TACs for 2012 compared with ICES scientific advice

Seafish summary of TACs agreed by the EU in December 2011 for 2012, compared with ICES scientific advice. The final table shows 97 stocks with the agreed TAC - colour coded relative to ICES advice. This shows 54 stocks in green - either below or comply exactly with ICES advice; nine stocks yellow - within 10% of ICES advice; six red – more than 10% above ICES advice; 28 stocks - with no colour as have not got all the information. There is an accompanying explanation for the yellow and red coding.

Sail Power (Part II)

This reports the development and testing a means of integrating sail power for use on commercial fishing vessels. This report is part two of the Seafish report SR630 and describes work carried out on the construction, deployment and testing of an innovative foresail on a 21 meter commercial fishing vessel, the MFV Nova Spero (CN 187). The sail was initially tested during instrumented sea trials in Mounts Bay in Cornwall and subsequently deployed during three commercial Tuna trips to the Bay of Biscay. This report includes details of the: • Construction and fitting of the Forestay and Foresail • Initial seal trials • Modifications made to the foresail and rigging • Results of instrumented sail performance trials • Commercial trials results • Future developments

Fishing spatial-temporal pressures and sensitivities analysis for MPA Fish-ing Industry Collaboration Pilot FES 252: Report on Seafish workshop on the physical effects of fishing activities on the Dogger Bank

This workshop, which is part of a larger project; Fishing Spatial-Temporal pressures and sen-sitivities analysis for MPAs (FES 252) carried out by NFFO and funded by EFF, is designed to review knowledge of physical actions on the seabed of fishing gear components and their envi-ronmental effects in order to contribute to this process of risk assessment.

Seafish Standard Sampling Operating Procedure_Basic Video Mapping Seabed Habitats

A lack of information on the precise location of a protected marine habitat or refuge for a protected marine species has caused considerable delays in environmental impact assessments and at worst led to applications to develop shellfish farms being refused or withdrawn as regulators are unable to decide whether the farm site and/or access arrangements will or will not have a potential impact on a protected wildlife site (Seafish 2006 & 2007).

Trials to Assess the Effectiveness of Ionization, Chlorination and UV Irradiation for the Disinfection of Seawater

Clean supplies of water are essential for the industry to maintain high standards of hygiene and quality. Where seawater is used, regulations demand that the water is free from microbiological contamination and that disinfection is carried out where required. In an operation such as shrimp processing where the product is cooled in seawater, cross contamination as a result of using contaminated seawater may result in food poisoning. It is thought that seawater containing a disinfectant residual may also be used to slow the microbiological spoilage of the product itself. For example using treated water in an RSW system may improve fish quality and extend shelf life. A series of practical trials were carried out to determine the effectiveness of electrolytic ionization, UV irradiation and chlorination for killing bacteria in seawater, with a view to the development of a commercial system for use on shrimp boats. A trial was also carried out to determine the effect on white fish quality of using ionized water in an RSW system. All treatments except chlorination using sodium hypochlorite proved to be unsuitable due to poor bacteriocidal performance and/or prohibitive costs. Sodium hypochlorite gave effective coliform bacterial kills at dose levels as low as 5 mg/1 of chlorine. A marginal improvement in quality was determined over a 7 day period with treated RSW versus untreated RSW.

Deep Water Fishing Along the North Atlantic Slope - Fishing Trials Onboard MFV 'Marantha III'

This report describes the findings of an experimental voyage of the MFV 'Marantha III' to the deep water grounds of the North Atlantic Slope. The primary objective of the voyage was to conduct a series of instrumental trials to assess the performance and power demands of both the propulsion engine and trawl winches when fishing at depths from 200-1000 metres. Fishing gear performance, the post harvest care of the catch and the results of quality assessments of the main deep water species are also discussed.
