B40_Abalone Feed Requirements

Abalone naturally eat seaweed of which some less abundant species are preferred. In culture situations where seaweed sources are considered it will be necessary to demonstrate that operations are sustainable to ensure no significant impact on the marine ecosystem. Furthermore, when abalone culture is proposed in Special Areas of Conservation (SAC’s) a higher level of ‘Appropriate Assessment’ will be required. This report is a guidance document to help address some of these issues and present options for individual scheme consideration.

SIPF0093 Innovative Shellfish System for High Energy Conditions (B080).l

A collaborative project was set up to monitor the performance of a new oyster growing system in a high energy environment, the Solway coastline, to investigate the performance of the system and to monitor any environmental changes that might be associated with its placement. The project suffered from serious losses of experimental trials and available growth data that is limited. Solway Marine Oysters have learnt a great deal about how to manage the system and there are indicationsfrom the data that regular sorting and redistribution of the oysters to optimize their size. The oysters produced are of good shape and free of any epibionts. A measurable change in the sediment and fauna associated with the location of the line was detected but whether this was due to the presence of the fixing posts, the growing bags themselves or other changes is not certain. Changes in the fauna were most likely related to the slight changes in the sediment present. The value of thetraining opportunity to one of the Solway Marine Oysters staff is acknowledged and there is an ongoing cooperation between the company and BST Ltd to further improve the operation of the system.

Investigating the use of low diameter twin for the construction of square mesh panels

This report involved a fishing trial to compare the performance of a square mesh panel made from heavy, high density double knotted netting with that of one constructed from a low diameter, high tenacity knotless material.

Lipids, egg and larval quality in cod

The project consisted of two studies on lipid quality and performance of cod broodstock (wild and farmed), eggs and larvae. Data suggested that arachadonic acid and carotenoid pigment concentrations in eggs from farmed fish may be sub-optimal. In trials where larvae were fed on enriched rotifers, the lipid profile of larvae reflected that of the live feed. Results of this and other studies indicate that relatively high DHA concentrations and DHA/EPA ratios, low EPA concentrations and EPA/ARA ratios and high ARA concentrations are advantageous.

B40_UK Legislative Status for Abalone Culture

South West Abalone Growers Association (SWAGA) aims to promote the sustainable development of abalone culture in the South West of the UK. In 2003 SWAGA undertook a FIFG Networking Project (FitzGerald 2003) to establish the limitations to the development of the industry of which legislative barriers were a significant feature.This legislative review has been produced as a guidance document for potential operators. Although it signposts the major legislative issues it is not exhaustive and prospective operators will need to establish site specific issues and requirements. It is also notable that there is considerable movement at present in a number of legislative areas and that any opinions provided in this report will be subject to change as interpretations evolve and regulations are updated.
