CONTROL OF SUPERSATURATION IN THE HATCHERY

Supersaturation can occur naturally in high-energy environments e.g. from wave action or dam spillways; or as a result of excess photosynthetic activity. In the aquaculture hatchery, supersaturation can be caused by a sudden increase in temperature e.g. in long pipe runs exposed to the sun, by entrainment of air through leaking joints or pump seals, or by injection of pressurised air at depth.

Trial of acoustic deterrents for prevention of porpoise by-catch (porpoise pingers) Phase 2 and 3 Endurance and Tangle

This study details the practicalities of attachment, deployment and testing of acoustic deterrents (porpoise pingers) within the Celtic sea gill net fishery.

Response to the Consultation on Fisheries Management in Luce Bay SAC

Seafish recognises the requirement to protect the environmental integrity of Luce Bay Special Area of Conservation (SAC), but is disappointed that no information was presented to substantiate the distribution and sensitivity of the seabed. The proposed fisheries management options should be considered in consultation with the fishing industry to ensure that they are truly effective and proportionate and to ensure they have an overall positive effect on the environment. The Scottish Government is reminded of the inshore vessel tracking project, run by Seafish and others, which is intended to demonstrate the potential of vessel tracking as a fisheries management tool.

Survey of Existing Good Manufacturing Practice Standards in the Fish Industry

The EU fish quality labelling and monitoring concerted action project brought together industry and scientists to establish common views on the subject. A series of international surveys were carried out as part of the project. The final survey investigated the operation of good manufacturing practice and standards in the fish industry and perceived needs for further standards. This report describes the UK results of that survey.

The Development of Multi-Rig Trawling Systems in the UK - Past, Present and Future?

Autonomous Scallop Harvesting Platform (ASHP)

The Autonomous Scallop Harvesting Platform (ASHP) is envisaged to be a self-contained automatic shellfish harvesting system. The concept is of a vehicle which moves underwater over a pre-determined search area and identifies and collects specified shellfish with minimal impact on the surrounding environment.

Economic Impact Assessment of the 2004 Fisheries Management Regime in the UK Whitefish Fleet

Seafish has developed a series of models, based on historical landings and costs and earnings data which predict the financial outcome for segments of the UK fleet, based on inputs of landings levels, fishing effort and fish selling prices. The model reflects a range of possible scenarios for the UK whitefish fleet in 2004.

An Integrated Traceability, Marketing and Back Office System for Inshore Ports and Vessels

In cooperation with commercial partners, Seafish has developed systems for weighing and labelling of boxed fish at sea in response to market and legislative requirements to provide accurate product defination and provenance at the point of first sale. This report describes how the data required by law or for trading may be captured and handled electronically on landing at small inshore ports to improve marketing and administrative efficiencies.
