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.

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.

Drift netting for tuna; the feasibility and costs of alternative fishing methods

This report describes work carried out under contract to MAFF. It examines the implications of the impending ban on high seas drift netting on that sector of the Cornish fleet that is currently licensed to fish for albacore tuna. More specifically, it covers investigations in the UK, Ireland and northern Spain into alternative fishing methods, the potential for converting the vessels in question and some of the market aspects of these changes. It is concluded that conversion to the trolling system of towed lines is the most appropriate option for the Cornish vessels, that this conversion could be carried out at a realistic cost, that crews could adapt to the necessary changes quite readily and that market opportunities would be open to re-equipped vessels. Given the current volatility of the global market for albacore tuna it is not possible to predict whether the converted vessels would be commercially viable. Indications are that, in the long term, conditions in Europe could be favourable to vessels that converted to trolling.

Fishermen's Environmental Monitoring Pilot - Exploring the Role of Fishermen in MPA and Environmental Monitoring

The evidence and data requirements for the designation and subsequent monitoring of MPAs place significant logistical and economic burden for official bodies. This report demonstrates how the fishing industry can play an integral role in marine monitoring and evidence collection using underwater video surveys as a model. Collaborative surveys are shown to have mutual benefits in terms of cost and efficiency savings, knowledge transfer and relationship building.

Bio-fuels for the fishing industry_Camborne School of Mines Report

This report details work carried out to investigate the performance of biofuels in marine diesel engines, relative to the use of fossil petrodiesel. The scope of work ultimately included: 1) The installation of a dynamometer test facility, equipped to run diagnostic and simulated operational duty cycles on marine diesel engines.

Aquaculture Opportunities for Enclosed Marine Water Bodies – Tidal Lagoon Swansea Bay Case Study

The SIP project output examines opportunities for aquaculture in/around enclosed marine water bodies, as well as the development of a generic design for a shellfish hatchery - the proposed Tidal Lagoon in Swansea Bay (TLSB) case study is a significant focus

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.

Seafood-waste disposal at sea – a scientific review

Due to the recent tightening of regulations surrounding the disposal of seafood processing waste to landfill, fish and shellfish processors are now facing a rise in the cost and difficulty of waste disposal. This is of particular concern in remote areas where alternative uses (e.g. fishmeal) are neither accessible nor economically viable and therefore, cost effective and environmentally-sound solutions to the disposal of this waste need to be found. This report examines the potential for disposal at sea, together with the likely impacts and advice on the selection of appropriate sites for disposal.
