The North Sea brown shrimp (<i>Crangon crangon</i> Linnaeus, 1758) fishery became Marine Stewardship Council (MSC) certified in 2017. As part of the certification, the fishermen proposed to incrementally increase the mesh size of the codend used from 22 mm to 26 mm. As this increase in mesh size could result in a substantial loss of marketable sized brown shrimp (shrimp with total length equal or ...

Siderophores are compounds with high affinity for ferric iron. Bacteria produce these compounds to acquire iron in iron-limiting conditions. Iron is one of the most abundant metals on earth, and its presence is necessary for many vital life processes. Bacteria from the genus <i>Serratia</i> contribute to the iron respiration in their environments, and previously several siderophores have been isolated ...

Games are vehicles that transport their players between different realties (Peters & Westelaken 2014). By doing this, they have the potential to provide many different benefits for their players, such as relaxation, excitement, social interaction, and learning. Higher education is increasingly trying to capitalize on this potential and many teachers now make use of different forms of game-based learning ...

This work contains a review of the undesirable substances that may be introduced as contaminants of natural and malicious origin, and of emerging hazards, in the production chain of farmed salmon,from ova to packed fillet.<p><p> The work, focused in the supply chain to European countries, contains a brief introduction to general food safety in relation to aquaculture products, followed by an ...

The Norwegian Scientific Committee for Food Safety (VKM) has been asked by the Norwegian Food Safety Authority to perform a health risk assessment on decomposition substances and oxidation products in fish oils intended for human consumption except pharmaceuticals. Seal and/or krill oil intended for human consumption might be included but in separate chapters. EU’s hygiene regulations for the ...

Salmon gill poxvirus (SGPV) can cause serious gill disease in Atlantic salmon (<i>Salmo salar</i> L.) and represents a significant problem to aquaculture industries in Northern Europe. Here, a single-tube multi-locus variable-number tandem-repeat (VNTR) analysis (MLVA) genotyping assay, targeting eight VNTR loci, was developed for studying the epizootiology of SGPV. Through MLVA typing of SGPV ...

<i>Aim</i> - To investigate the use of game‐based learning (GBL) to enhance students’ experience of the flipped classroom (FC) in dental education.<p> <p><i>Materials and Methods</i> - Students participated in three sessions organised as FC, implemented either as conventional FC or FC augmented with the GoDental! game. In the pre‐class phase, sessions 1 and 2 were organised as instructor‐made ...

In the deep sea trawl fishery targeting shrimp (Pandalus borealis) and other cold-water shrimp species, fishers often use a Nordmöre sorting grid ahead of a small mesh codend to avoid bycatch. However, small fish can pass through the grid and are subsequently retained in the codend. This makes shrimp size selection complex and the size-dependent curve for both the shrimp and the bycatch species often ...

To prevent unwanted fish bycatch from entering the trawl, we modified a counter-herding device, FLEXSELECT, developed for a Northeast Atlantic <i>Nephrops</i> (<i>Nephrops norvegicus</i>) trawl fishery. FLEXSELECT, which was designed to direct fish away from the trawl by means of sweeping ropes in the herding area, has been shown to be highly effective on both roundfish and flatfish species. However, ...

Despite their contribution to employment, food security, poverty eradication, and community well-being, small-scale fisheries often find themselves in a disadvantageous position globally relative to large-scale fisheries and other industries competing for marine space, resources, and government attention. By and large, small-scale fisheries are marginalized in every sense of the word: culturally, ...
