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.

Presentations given at Seafish 'Social Responsibility in Seafood' workshop. Malta. January 2016.

Seafish facilitated the pre-summit workshop at the Seaweb Seafood Summit in Malta on Sunday 31 January 2016. The topic was ‘Social Responsibility in Seafood’. This workshop presented the ongoing or developing initiatives that aim to eliminate social and ethical concerns in the seafood industry, as well as map these initiatives throughout the supply chain. There were 14 powerpoint presentations which have been collated here. Please also see the handout and the summary note on the workshop.

Use of Ozone in the Fish Industry

Remote Closure of Sea Inlets

Over half of fishing vessel losses are attributed to flooding, mainly due to the failure of pipes and fittings in the engineroom. Often, when flooding is discovered the crew find it impossible to reach and close the sea inlet valves to stop the flow of water and the vessel is lost. John Buchan, a retired engineer from Peterhead, had an innovative idea to enable the remote closure of sea inlet valves and this report describes the development of his ‘Hydraclose’ concept and a demonstration installation on a 25.6m vessel. Companies in Peterhead and Fraserburgh have developed this system and the Scottish Executive has given major support by the provision of a FIFG grant towards the vessel demonstration costs.

Fisheries Management Issues Report

The Fisheries Management Issues Report summarises some of the current issues affecting the UK fishing industry. Information is collated from regional, UK and European sources and regular topics include discussions at the EU Fisheries Council meetings, official landings into the UK relative to allocated quotas and the extent of bans on fishing due to shellfish poisoning around the UK.

Report from an international workshop on seine net fishing held in Keflavik, Iceland, May 08

With the growing interest in this relatively fuel-efficient method of fishing, the college invited speakers from Iceland and across Europe to share their experience and expertise in seine netting (also known as Danish seining, as this technique has its origins in Denmark). Lárus Thór Pálmason, the college’s senior lecturer in fishing gear technology and principal organiser of the event explained that rising fuel prices had driven a growing interest in seine net fishing and the college had been approached informally on several occasions to show groups of fishermen and vessel owners from other countries how seine net fishing works. The visits allowed an insight into how fishermen from other countries were dealing with the problems related to high fuel costs and looking to methods such as seine netting as one way of mitigating the problem. Programmes for visiting fishermen included visits to fishing gear suppliers, some gear simulation sessions in the small flume tank which the college has, and the chance to spend a day at sea with a working boat. These visits have been so popular that it was decided that it would be a good idea to try and pool a lot of the information that has been gathered into a workshop, and hence the international workshop was arranged.

Notes on Seafish 'Social License to Operate' workshop. London. 28 June 2016.

A social license to operate indicates the level of approval from the community that an industry has to operate. Seafish facilitated a workshop to explain the concept, how it works and the reasons for attaining and building high quality stakeholder relationships in this way. These notes are a summary of the workshop, the exercises undertaken and the comments made. Please also look at the presentation given at the workshop and the handouts which can all be found on the Seafish website http://www.seafish.org/responsible-sourcing/discussion-forums/the-common-language-group/social-license-to-operate.

Performance of a trawl codend made from 90º turned netting (T90) compared with that of traditional codends

This paper describes a series of tests conducted in the SINTEF Flume Tank with different designs and constructions of codends.

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.

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.
