Culturing of Norway lobster (Nephrops norvegicus)_Aggression in Nephrops

The first aim of this project was to examine and gain a better understanding of the aggressive behaviour of the animals. Aggressive behaviour, causing injury or death, is thought to be a major obstacle in keeping animals in communal tanks. It was found that the Norway lobsters are able to build a dominance hierarchy, which reduces overall aggression in communal tanks. Moreover, it was found that pheromones are necessary for establishing dominance. Follow up studies will aim to gain a better understanding of the role of aggression in natural behaviour including territoriality,resource competition and mate choice. The second aim is to develop economic holding conditions for the animals. Holding animals in communal tanks is thought to be easier to manage - in terms of feeding and maintaining good water quality - than keeping them separately. Ongoing experiments comparing holding conditions indicate that there seems to be no difference in survival rate between individual and communal holding conditions. The third aim is to decide upon the best methods of collecting eggs and to hatch them. This will be researched in the next two years. Eggs will be collected by catching berried females. Holding conditions will be tested to maximize the hatching rate of the four larval stages in the lab. The results of the study will improve the understanding of the species which could help drive better stock management. In addition, it could support the fishing industry by providing sustainability and reducing the influence of natural barriers to fishing, such as weather conditions.

Sodium Metabisulphite Alternatives

Sodium metabisulphite has been used in the UK fishing industry for many years to control the effects of melanotic blackening in prawns (Nephrops norvegicus). Recent requirements for allergen labelling and court cases resulting from high levels of sulphite residue have prompted interest to secure alternative treatments to control melanosis. Further motivation has come from the highly corrosive nature of sodium metabisulphite. This causes extensive damage to vessels and processing equipment and has serious operational health and safety issues. A number of treatments were trialled in a commercial environment to determine a viable alternative to sodium metabisulphite. Prawns were treated at sea and then assessed for shelf life and sulphite residue by processors in NE Scotland. 5 treatments were competitive with sodium metabisulphite, these include sulphite based and non sulphite based treatments. As such, vessels and factories are provided with a variety of treatment options depending on their own product requirements. Alternative sulphite based treatments exhibit reduced operational hazards and lower sulphite residues in the tail meat while selected non sulphite based treatments are classified as ‘processing aids’ and are exempt from any form of food additive labelling.

Economics of the UK Fishing Fleet 2020

The report presents economic estimates at UK, home nation and fleet segment level for the UK fishing fleet. The estimates are calculated based on samples of fishing costs and earnings gathered by Seafish as part of the 2020 Annual Fleet Economic Survey.

Seafish Discards Q&A

Seafish answers the key questions being raised about the issue of discards in fishing. This publication covers what are discards, what causes discarding, initiatives in place to address discard levels, how the EU is addessing the issue through the CFP, what is being done to improve survival rates and what the fishing industry can do to reduce discard levels.
