This research focuses on biochemical changes related to quality losses observed in Atlantic mackerel (Scomber scombrus) muscle stored under commercial frozen storage conditions (9 months, -18 ºC) when subjected to high-hydrostatic pressure (HHP) treatments (125, 150, 175 and 200 MPa for 0 min) before freezing. After freezing, free fatty acid...
This work focuses on the effect of a previous high pressure processing (HPP) on the lipid damage development occurring during the frozen storage (-10ºC; up to 3 months) of Atlantic horse mackerel (Trachurus trachurus). HPP conditions included different pressure (150, 300, 450 MPa) and pressure holding time (0.0, 2.5, 5.0...
This work focused on assessing lipid damage during the storage of frozen Atlantic mackerel (Scomber scombrus) subjected to a high hydrostatic pressure (HHP) treatment (150, 300, 450 MPa with holding times of 0.0, 2.5, and 5.0 min) prior to freezing. The extent of lipid hydrolysis (free fatty acids) and oxidation...
Integrating governance mechanisms into bio-economic modeling tools is a key challenge for the assessment of fisheries management plans. Impact assessments are carried out without considering real management options and institutional context. Only fishing mortality changes and their impact on fish stocks are considered. The Bay of Biscay sole fishery offers...
English: Clostridium difficile is an emerging anaerobic, spore forming pathogen, recognized as the etiological agent of ~ 30% of antibiotic associated diarrheas. Clinical symptoms can fluctuate from mild to moderate diarrhea, pseudomembranous colitis and toxic megacolon. The incidence of C. difficile associated infections (CDAI) is ~ 1% of total hospitalized...
A vessel-based bio-economic model (IAM) is presented and applied to the Bay of Biscay sole fishery to investigate alternative quota management systems from a multi-criteria perspective. For this study, the model integrates several institutional arrangements related to catch share management. The current French co-management system with non-transferability of quota is...
This work is part of the SUCCESS project (Work Package 4: Competitiveness and sustainability of European fisheries and Aquaculture sectors) funded by the EC (H2020, GA 635188). The dynamics of the value chain in eight different species at the Spanish market has been studied using price integration methodologies. Cases of...
Production data from the red grouper fishery, Mexico, were analyzed to determine the production function. Three different models were tested in cross-sectional data from the period 1988 to 2014. The data were collected from the logbooks provided by skippers. Number of fishermen (crew) per trip varied from 3 to 15,...
Purpose: This study attempted to identify skills needed in agriculture for rural youth in Honduras, and to develop an appropriate agricultural education curriculum at the Common Cycle of General Culture (lower Middle School level) of the current educational system. Methods and Procedures: Core competencies were identified by collecting information from...
European seabass and gilthead seabream are two economically important cultured fish species along the Mediterranean coast. Both species represent respectively 10.9% and 13.5% of the total value of the European aquaculture sector (Eurostat, 2013). The EU is one of the largest producers of seabass and seabream in the world, being...
