Abstract Lumpfish ( Cyclopterus lumpus L.) are increasingly being used as cleaner fish to control parasitic sea lice, one of the most important threats salmon farming. However, lumpfish cannot survive feeding solely on and their mortality in net‐pens can be high, which has welfare, ethical economic implications. The industry is under increasing pressure improve welfare lumpfish, but little guidance exists how this achieved. We undertook a knowledge gap prioritisation exercise using Delphi...
The clawed lobsters Homarus gammarus and americanus are high-priced appreciated food items in southern Europe. From a nutritional point of view there is still limited information on the chemical composition edible tissues (muscle, hepatopancreas, gonads) both species. Therefore, aims present work were to study proximate composition, energy, fatty acid amino profiles, cholesterol content each tissue species evaluate their quality. Differences observed between tissues, sexes, Muscle gonads...
Cancer pagurus is most appreciated in southern Europe for its muscle and brown meat content. In Portugal, consumption occurs mostly summer at Christmas. this study the seasonal nutritional quality of edible tissues female male C. was determined. Tissue composition affected by season sex. All had a well-balanced essential amino acid composition. Muscle gonads females n-3/n-6 ratios range usual recommended values, all PUFA/SFA above level. Autumn with highest yield, total acids (muscle),...
Abstract Barrento, S., Marques, A., Pedro, Vaz-Pires, P., and Nunes, M. L. 2008. The trade of live crustaceans in Portugal: space for technological improvements. – ICES Journal Marine Science, 65: 551–559. In Portuguese coastal areas, crabs lobsters maintained alive until prepared the table are commercially economically very important. crustaceans, mostly imported animals, is an interlinked complex chain, from fishing, collection, holding facilities, transportation, to end-consumer, various...
Abstract Barrento, S., Marques, A., Vaz-Pires, P., and Nunes, M. L. 2010. Live shipment of immersed crabs Cancer pagurus from England to Portugal recovery in stocking tanks: stress parameter characterization. – ICES Journal Marine Science, 67: 435–443. is commercially one the most important crustaceans exploited UK Ireland, but main markets are southern Europe, where live edible transported. In this study, potential stressors during trade chain were identified related changes haemolymph...
Cancer pagurus is much appreciated in Southern Europe, where the muscle, hepatopancreas, and gonads are consumed regularly with peaks summer December. The elemental contents of C. edible tissues were analyzed this study during four seasons. Results indicate that content varied tissue, season, sex. hepatopancreas had more S, Cl, Ca, Br, Sr, Fe, Cu, Cd, Pb, a higher concentration Na, muscle was richer Zn. Autumn winter corresponded to high Mg, K, Zn both hepatopancreas. Female Zn, As, Se than...
Seaweeds can be a valuable resource for biorefinery and biotechnology applications, but their high water content is recurrent problem one of the key bottlenecks sustainable use. Treatments to increase dry matter kelp Laminaria digitata were recently described by authors. However macroalgae are an extremely diverse group organisms compositional variation between species may influence effects particular treatments. In this study, potential dewatering treatments including drying, osmotic media,...
The mussel (Mytilus edulis) is successfully grown in aquaculture Europe. Mussels are usually sold live and wet storage becoming more common. In this study, oxygen demand ammonia excretion were assessed at increasing water temperatures different post-harvest situations. This information was used to calculate minimal flow rates per unit biomass of mussels sufficient keep above 5 mg L-1 or 50% saturation, avoid accumulation commercial storage. rope-grown kept out for 8 h simulate harvesting...
The trade of live Cancer pagurus in Portugal is totally dependent on imports, mainly from UK. Animals are transported for 48–58 h conditions that promote high mortalities (40–60%) due to cumulative stressors. present work aimed optimize transport, by comparing the physiological responses edible crab during different simulated shipment systems 48 and recovery conditions: (a) immersed crabs at 12°C; (b) air-exposed 4°C subsequent 16°C with without pre-acclimation. Both transport induced...
Abstract Bladed Bangiales of the genus Porphyra/Pyropia are highly valuable red algae and extensively farmed in South East Asia. Interest is rising cultivating species local to North Atlantic but control heteromorphic life cycle native remains difficult as previous studies reported high inter- intraspecific variability required cultivation conditions. Here, working with Porphyra dioica from a UK source population, we conducted series experiments investigating influence substrate,...
Abstract BACKGROUND: Macro and trace elements have significant impacts on human health. Yet, information of elemental content in seafood is still scarce. Green crab Carcinus maenas velvet Necora puber are mainly caught off English, Scottish French coastal waters live transported to Southern Europe, where they consumed. During transportation, mortalities can reach 50% dead animals regularly commercialized for consumption. The present study characterises the composition both species. RESULTS:...
Aquaculture is one of the fastest growing food producing sectors; however, intensive farming techniques finfish have raised environmental concerns, especially through release excessive nutrients into surrounding waters. Biodiversity has been widely shown to enhance ecosystem functions and services, but there limited testing or application this key ecological relationship in aquaculture. This study tested applicability biodiversity-function integrated multi-trophic aquaculture (IMTA), asking...
