A new bycatch reduction device, termed “Excluder”, is presented as an alternative to a traditional rigid sorting grid, mandatory in the small-meshed Norway Pout (<i>Trisopterus esmarkii</i>) trawl fishery in the North Sea. The fishery is a high-volume fishery with large vessels, large demersal trawls and catches up to 100 tons per haul of this small forage fish. The Excluder is a 30 m long netting-based ...

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 ...

The European Union has been applying a top-down and centralized approach to management of fish stocks to try dealing with the complexity of the marine environment. Since the establishment of the Common Fisheries Policy in 1983 the principle of relative stability has maintained the main resource “conservation” component of the policy, despite all its criticism for being the major driving factor for ...

A novel bioactive peptide named τ-AnmTx Ueq 12-1 (short name Ueq 12-1) was isolated and characterized from the sea anemone Urticina eques. Ueq 12-1 is unique among the variety of known sea anemone peptides in terms of its primary and spatial structure. It consists of 45 amino acids including 10 cysteine residues with an unusual distribution and represents a new group of sea anemone peptides. The 3D ...

A new species of the rare, deep-sea genus Sciadonus Garman, 1899 (Bythitidae) is described based on two specimens obtained by the Brazilian R/V Alpha Crucis on the continental slope off São Paulo State, Southeastern Brazil, western South Atlantic. It differs from its congeners by the combination of the following characters: body pale lacking dark pigmentation except for on female claspers; a pair ...

Organiseringa av førstehåndsomsetninga i Norge er unik, og tillitsbasert. At noen, med overlegg, bryter denne tilliten med å omgå regelverket i førstehåndsomsetninga, er kilde til frustrasjoner for de som driver ærlig, og tar fra fellesskapet. Den felles holdningen som kommer frem i denne undersøkelsen er at det å omgå regelverket er galt, og at det ikke er noen gode unnskyldninger for å gjøre det. ...

<ol> <li>Metabarcoding extra‐organismal DNA from environmental samples is now a key technique in aquatic biomonitoring and ecosystem health assessment. Of critical consideration when designing experiments, and especially so when developing community standards and legislative frameworks, is the choice of genetic marker and primer set. Mitochondrial cytochrome c oxidase subunit I (COI), the standard ...

Lumpfish (Cylcopterus lumpus) is increasingly used as cleaner fish in intensive farming of Atlantic salmon (Salmo salar) with an aim to control the infection of lice on the salmon. The lumpfish is itself exposed to a number of infections, both bacterial, viral, parasitic and fungal, and there is still a lack of knowledge regarding these infections and their impact on the fish. In order to assess the ...

Sosiale medier har tatt verden med storm og bare Facebook alene har over en milliard aktive brukere. Mange selskaper ser derfor en mulighet til selv å benytte sosiale medier til å nå ut til sine kunder og forbrukere. Denne studien har tatt utgangspunkt i dette og har som formål å få et innblikk i hvor langt produsenter av norsk fisk- og sjømat har kommet i implementeringen av sosiale medier i ...

Formålet med denne mastergradsoppgaven er å undersøke hvilke faktorer som påvirker norske husholdningers valg av butikk ved kjøp av middagsmat. Problemstillingen setter fokus på kjøpsfrekvens i utvalgte butikker, og søker å profilere ulike segmenter ved hjelp av holdningsvariabler og demografiske variabler. Kunnskap om hvilke butikker norske husholdninger gjør sine innkjøp i og hvilke holdninger de ...
