Alternative Marine Conservation Zones in Irish Sea mud habitat: potential for fisheries displacement and an assessment of habitat condition and potential management scenarios.
Areas of potential alternative Marine Conservation Zone (MCZ) sites representing mud habitat within the UK Irish Sea regional sea were selected at a stakeholder engagement meeting in October 2014. In order to assess the suitability of these sites within the Irish Sea regional area, existing data were examined to assess habitat condition, variation and how well these meet the mud habitat criteria set by the UK government. Nephrops stock assessment video surveys were utilised along with grab sample data, across both eastern and western Irish Sea areas. Macroinvertebrate community analysis was undertaken on the grab infaunal data, along with analysis of sediment parameters. The level of disturbance was also examined through benthic community assessment relating to successional stage. -
Environmental Data Gathering for Environmental Assessments_Basic Seabed Habitat Mapping using Acoustic Ground Discrimination Sonar and Underwater Video
A lack of information on the precise location of a protected marine habitat or refuge for a protected marine species has caused considerable delays in environmental impact assessments and at worst led to applications to develop shellfish farms being refused or withdrawn as regulators are unable to decide whether the farm site and/or access arrangements will or will not have a potential impact on a protected wildlife site (Seafish 2006 & 2007). -
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. -
Beach Seining
Seining is a fishing technique traditionally done in areas with large schools or groups of fish. -
Seafish Insight: Fishing references by country in 2018 U.S. TIP Report. June 2018
The Trafficking in Persons (TIP) report is the U.S. Government’s principal diplomatic tool to engage foreign governments on human trafficking. It is also the world’s most comprehensive resource of governmental anti-human trafficking efforts. The U.S. Department of State Trafficking in Persons report (TIP) 2018 was published on 28 June 2018. This document lists the references to fishing by country. -
Fuel Systems Testing - Determinations of the effect of (electro-) magnetic installations, a fuel additive and a lubricant additive on diesel fuel consumption
On 6th March 2008 representatives from SeaFISH and the University of Exeter met to discuss testing of fuel economy enhancement technologies at the CSM dynamometer test cell facility. These discussions resulted in an order for testing of various technologies to determine their effectiveness. The proposed technologies were varied in nature, ranging from the use of permanent and electromagnets installed on fuel lines to performance exhaust systems and engine lubricant conditioners. For each of these technologies, engine performance and fuel consumption tests were undertaken once without the technology deployed, then once with the technology installed. The results from the two tests were compared. -
Complementary Benefits of Alternative Energy: Suitability of Offshore Wind Farms as Aquaculture Sites
The large scale growth in salmon production in the UK has resulted in most available near shore finfish sites being used up for finfish farming. The development of offshore sites or technology improvements alone hold the key for the sustained growth of the UK aquaculture industry. The offshore wind industry has been rapidly expanding in the UK and will occupy major amount of coastal offshore space when zoning plans are developed. The prospects for using the offshore wind farm areas for aquaculture production (finfish and other species) has the potential to open up new sites for finfish farming in the UK. This work examined the suitability of aquaculture in offshore wind farms from the point of view of all the stakeholders involved. -

Design of a containerised biodiesel production plant
This report details work carried out in assembly of a prototype containerised batch production plant that is portable and suited to deployment quayside to support fishermen that wish to selfmanufacture biodiesel. The biodiesel batch plant has a maximum production capacity of approximately 210,000 litres per annum when working one shift and approximately 420,000 litres per annum with 24 hour working. -

Appraisal of the opportunity for offshore aquaculture in UK waters
This report provides an assessment of the potential for open ocean, offshore finfish aquaculture in UK waters using candidate species which would have similar growth and performance characteristics to Atlantic salmon (Salmo salar) and Atlantic cod (Gadus morhua) and with due reference to other potential species candidates.
