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, ...

Rapporten er en helhetlig vurdering av mulige grep innen arealforvaltning (arealplanlegging og lokalitetsforvaltning) av havbruk og marine områder for å gjøre areal tilgjengelig for vekst i havbruksnæringen, samtidig som også andre hensyn sikres, og at forvaltningen er tids- og kostnadseffektiv. Hvordan tilgangen på egnede arealer vil bli for næringen fram mot 2030 og videre, vil avhenge av flere ...

Two adult specimens of the tropical to subtropical fish species <i>Diretmichthys parini</i> are reported from the North Sea and the northern Norwegian Sea, respectively. Both were accidentally caught as bycatch by commercial trawlers. Although not uncommon in Icelandic waters, it has not been documented from the Nordic Seas previously. In light of the major currents and water temperatures in the ...

This conference paper presents the case of using a combination premade serious games and self-designed games at bachelor and master’s programs at the Norwegian College of Fisheries Science to facilitate the integration of different disciplines and the development of practical skillsets that are necessary for success in the seafood industry after graduation. Furthermore, it explores the preliminary ...

This study reports the isolation of two novel cysteine-rich antibacterial peptides, turgencin A and turgencin B, along with their oxidized derivatives, from the Arctic marine colonial ascidian <i>Synoicum turgens</i>. The peptides are post-translationally modified, containing six cysteines with an unusual disulfide connectivity of Cys<sup>1</i>-Cys⁶, Cys²-Cys⁵, and ...

I dette prosjektet har vi testet ut en hypotese om at ved å erstatte vegetabilske oljer i fôr til oppdrettslaks med marine oljer, vil man kunne redusere lusepåslag hos laks. Vi har fôret laks med fire ulike fôr, der proteininnholdet er det samme, men oljen er variert. De ulike fôrene vi brukte var kontrollfôr som var standardfôr med vegetabilsk olje, og tre ulike testfôr der vegetabilsk olje ble ...

The shellfish aquaculture industry has dramatically developed during the last two decades. However, this development has, in some cases, resulted in environmental degradation, emergence of diseases and low productivity. The need for improving disease resistance, growth performance, feed efficiency, and safe aquatic production for human consumption has stimulated development and applications of ...

Verden har et økende behov for mat samtidig som det legges stadig større press på ressursene. Det er mange måter å produsere mat og sjømatproduksjon er en av dem. Sjømat er av mange ansett som en av de viktigste matkildene i fremtiden. Produksjon av fersk fisk er blant disse. Sjømatmarkeder for fersk fisk stiller krav om leveransestabilitet, kvalitet og bærekraft. Det fins tre prinsipielt forskjellige ...
