Land application of shellfish by-products

Shellfish waste currently has few, if any readily available recycling outlets. Application of the waste to agricultural land as an organic manure has been identified as the lowest cost disposal route available to the majority of the seafood industry. An in-depth review of landspreading shellfish waste was carried out in 2006 to identify the possible benefits of using shellfish on land. This included an in-depth literature review, contacting people with experience of using shellfish waste on land, analysing some shellfish samples to assess their composition etc. The study found that shellfish could have benefit in land application for agricultural purposes and that it remained a viable outlet for shellfish waste providing compliance with legal constraints such as animal by-product legislation and waste management licensing is demonstrated. This report provides an overview of the information collected, including summarising shellfish properties and beneficial properties to land. It also provides an overview of how permission for the land application of shellfish by-products can be obtained.

Effects of electrofishing for Ensis spp. on benthic macrofauna, epifauna and fish species. SR652

This report summarises the results of experimental work carried out as part of “Design and Trials of Electrofishing System for Razorclams – FIFG 57437 and Seafish IPF funding project C85”. The aim of the project was to design and trial methods of harvesting Ensis spp. using electrical stimulus with the intention of providing a more environmentally benign alternative to existing hydraulic and toothed dredges. The results of this study demonstrate that the effects of electrofishing gear employing relatively low DC voltage and amperage can be effectively used in the harvest of Ensis spp. without serious negative effects on the epifaunal and macrofaunal benthic community.

Use of waste as a biofuel and fertiliser in Orkney_C008

Shellfish processors want simple, local, cost-effective solutions for managing shellfish waste. Anaerobic digestion (AD) has been identified as a potential solution for shellfish waste treatment. The process produces methane which can be used to generate energy and digestate (fertiliser) which has applications in agriculture and horticulture. Heat and Power Ltd. were part funded by Seafish to evaluate the potential of AD as a solution for Orkney based shellfish and food processors. The main aims of the project were to consider whether AD could reduce commercial waste disposal costs and establish a sustainable waste management solution for the island. It included a small-scale batch digester trial on crab shells. This report summarises AD technology, suitable food wastes in Orkney and results of a small-scale batch trial on crab processing waste.

De-infestation of slipper limpets from mussel seed

The mussel culture industry is one of the largest and most valuable fisheries in the UK representing almost 90% of total shellfish aquaculture production by weight in England and Wales with a value of around £14 million per year. Continuing productivity is significantly dependant on the movement of mussel seed from wild settlement areas to cultivation areas. Unfortunately, these shellfish movements can also spread pests such as the non-native slipper limpet (Crepidula fornicata) which has the potential to have a devastating effect on both fisheries and marine eco-systems as it out-competes other species for food and space as well as depositing pseudo-faeces that builds up to create cohesive ‘muds’. An accidental introduction of slipper limpets into the major UK mussel culture area of the Menai Straits, North Wales has recently occurred following a movement of mussel seed contaminated with slipper limpets from the English Channel. This led to urgent remedial action having to be taken by industry which involved removing the infested mussel seed and then smothering of any remaining slipper limpets with new slipper limpet free seed. There is a need therefore for the industry to self regulate and minimise risks in such transfers. Failure to do so will otherwise result in measures being imposed on industry in this respect. Positive action is now currently being undertaken in some regions as can be seen by the development of a Code of Good Practise by the Bangor Mussel Producers.

Development of a suitable dredge for exploitation of razorfish (Ensis directus) in The Wash

This report describes a study of the environmental effects of razorfish dredging within a SAC (Special Area of Conservation) under the Habitats directive. The study includes instrumentation, environmental modeling and was used as an appropriate assessment under for the experimental fishery for this species in The Wash.

Pilot Trials to determine the benefits of high pressure processing (HPP) for seafood in the UK: Phase 1 Report

High pressure processing studies were carried out on 11 species of fish and shellfish in order to determine whether there were any potential processing benefits for the UK seafood processing industry. The species tested were: Nephrops norvegicus, mussels, oysters, crab, cold water prawns, lobster, warm water prawns, unsmoked salmon, squid, mackerel and cod. In each case, a 20-run experimental design was employed and six of the 20 runs (from a single design block) were evaluated for sensory quality compared with a control sample. After processing, all 20 runs were evaluated for survival of TVCs, coliforms and pseudomonads. In some products, measurements of yield were carried out to determine whether HPP offered any processing benefits, e.g. for peeling, picking or shucking of seafood.
