Abstract The combustion of fossil fuels is considered a major cause climate change, which why the reduction emissions has become key goal Paris agreement. Coherent monitoring energy profile fishing vessels through an audit can effectively identify sources inefficiency, allowing for deployment well-informed and cost-efficient remedial interventions. We applied audits to test fleet ten vessels, representing three typical Mediterranean trawl fisheries: midwater pair trawl, bottom otter Rapido...
Discarding is considered globally among the most important issues for fisheries management. The recent reform of Common Fisheries Policy establishes a landing obligation species which are subject to catch limits and, in Mediterranean, Minimum Conservation Reference Size (MCRS) as defined Annex III Regulation (EC) No 1967/2006. Additionally, several other initiatives aim reduce unwanted catches target and bycatch species, including conservation concern. This raises need study discarding...
This paper presents preliminary evaluations on the design of hybrid propulsion architectures related to midsize boats. The analysis is carried out for case study a retrofit operation proposed an oceanographic ship, which used by researchers National Research Council Italy experimental campaigns in Mediterranean Sea. Starting from information obtained existing architecture means various on-board inspections, set-up monitoring and acquisition main electrical mechanical parameters during her...
This paper presents energy and power evaluations on propulsion generation systems related to a research vessel, named G. DALLAPORTA. vessel is used by the National Research Council of Italy for oceanographic campaigns, which are generally carried out in Mediterranean Sea. The analysis based measurements main electrical mechanical parameters, board propulsion, oleodynamic electric auxiliary systems, with reference original thermal configuration ship. These preliminary results, obtained...
Abstract The catch performance of a traditional Ligurian boat seine, which is not in line with the European Union regulation, was compared an experimental surrounding net without purse as potential legal alternative. relative between two gear types assessed using new comparison method requiring neither paired data collection nor equal number hauls gears. based on catches three species that comprise bulk seine fisheries: Bogue Boops boops, Saddle Bream Oblada melanura, and Blotched Picarel...
The current legal codends used in Mediterranean bottom trawl fisheries are at high risk of retaining undersized individuals several commercial fish species. This entails that alone unable to provide the desired exploitation pattern. A simple technological measure potentially can higher release efficiency Square-Mesh Panels (SMPs). SMPs often applied upper section belly, just ahead codend. However, recent studies have demonstrated mounted this position provided limited efficiency, because...
This study illustrates some potential applications of side-scan sonar to explain issues related fisheries science. Side-scan enabled identification the footprint different trawl types. It showed that a twin sweeps 30% greater area than traditional and semipelagic door has more limited impact bottom otter trawl. The detection characterization interaction gear with seafloor. demonstrated cod end is floating above sea during tow, while doors clumps, bridles have most damaging effect on was used...
Fishing pressure is often expressed in terms of vessel's physical attributes, like tonnage and engine power, while a common definition fishing capacity identifies vessel size as convenient proxy for the gear used. Nevertheless, these definitions remain arguable, refinement descriptors increasingly receiving growing consideration. A stronger understanding relationship between standard measures effort mortality remains primary objective, followed by need to overcome traditional approach that...
High fuel consumption coupled with increasing prices, emission regulations and concern about the environment, act as incentives to reduce energy of ships. However, different barriers hinder adoption cost-effective saving measures by ship owners operators. These are reason for existence an ‘energy efficiency gap’ between current level potential development higher order efficiency. Imperfect information regarding vessels, availability application measures, impact adopting these form a group so...
In the last few decades, cuttlefish market has grown to approximately 14% of world’s fisheries, and operators have begun express concerns about decline this resource. context, production through aquaculture could offer a diversifying valuable response increasing demand help alleviate environmental pressure on species. Therefore, aim study is identify dry, cost-effective, easy-to-administer diet that can successfully support initial phases growth provide similar performance krill-based diet,...
