Epibenthic predators in estuarine shallow soft-bottom environments are generally considered to have broad ecological niches with a wide overlap. This allows them to cope with abundant but highly variable prey communities. The assessment of trophic relationships in shallow soft-bottom habitats is, however, challenging and often complicated by the bias and low resolution of the analytical tools available ...

<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 ...

The existing management system in the Russian fishing industry was created as a result of the political, economic and institutional transformations that took place in Russia after the dissolution of the Soviet Union in 1990. This thesis analyses the processes in the fisheries that led to the establishment of the existing institutional and management practice. The study seeks to find out how the ...

This thesis is dedicated to studying the main factors which could affect Norwegian cod by-products in the Chinese market. Norway has been recognized as one of the biggest seafood countries in the world while China shows a preference towards Norwegian seafood. And due to the relationship has been better in the past few years between these two countries, it is worthy to discuss Norwegian seafood ...

The global problem of microbial resistance to antibiotics has resulted in an urgent need to develop new antimicrobial agents. Natural antimicrobial peptides are considered promising candidates for drug development. Echinoderms, which rely on innate immunity factors in the defence against harmful microorganisms, are sources of novel antimicrobial peptides. This study aimed to isolate and characterise ...

A novel brominated alkaloid, Securidine A, was isolated from the cold water marine bryozoan Securiflustra securifrons. Securidine A was isolated using semi-preparative HPLC, and the structure was elucidated by spectroscopic methods. The isolated Securidine A was tested for cytotoxic, antibacterial, and anti-diabetic activities as well as for its potential for inhibition of biofilm formation. No ...

Species are redistributing globally in response to climate warming, impacting ecosystem functions and services. In the Barents Sea, poleward expansion of boreal species and a decreased abundance of Arctic species are causing a rapid borealization of the Arctic communities. This borealization might have profound consequences on the Arctic food web by creating novel feeding interactions between ...
