Background. Although, presence of tannase-producing and/or tannin tolerant gut bacteria has been documented in ruminants and non-ruminant herbivores, the topic is rarely addressed in fi sh. The present study aimed at enumeration of autochthonous tannase-producing bacteria in the gut of freshwater teleosts. <p> Materials and methods. This study covered seven freshwater teleost fi sh species: rohu, ...

This study addressed the effects of dietary Lactobacillus plantarum or/and N-acylated homoserine lactonase (AHL lactonase) on controlling Aeromonas hydrophila infection in juvenile hybrid tilapia (Oreochromis niloticus♀ × O. aureus ♂). Fish were fed Lb. plantarum subsp. plantarum strain JCM1149 (108 CFU/g feed) or/and AHL lactonase AIO6 (4 U/g) and were exposed to a chronic challenge of A. hydrophila ...

Coastal states around the world are currently adopting an integrated and ecosystem-based approach to the management of coastal and ocean areas. The main aim is to promote resource use while protecting the integrity of the marine ecosystems. Focus is therefore on the conflict between economic development and conservation. Less attention is paid to the complex uses of the ocean and the conditions for ...

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 ...

The overall goal for CRISP (WP 5) is to contribute to, and develop, the competitive power of the trawling fleet by implement new technology and knowledge. The focus is on the processing, from when the fish is in the trawl at the seabed until the processed and finished raw material is packed and in storage.

Hva er de viktigste legitimitetsutfordringer i kvote- og ressurspolitikken? I denne rapporten forsøker vi å gi svar på dette spørsmålet.

Fiskeridirektøren og det tilknyttede reguleringsutvalget og forvaltningsorganene flyttes fra Bergen til Tromsø, i det minste den delen som angår forvaltningen av ressursene utenfor Nord Norge, foreslår artikkelforfatterne.

This is the second report from the project “Impacts of the legal framework on the aquaculture industry – simplification of regulations”, funded by The Norwegian Seafood Research Fund (FHF). The project is designed to investigate how scientific knowledge and political objectives have shaped the design and implementation of the legal framework, and to suggest possible improvements and simplifications ...

Several common protein extraction protocols have been applied on seaweeds, but extraction yields have been limited. The aims of this study were to further develop and optimize existing extraction protocols and to examine the effect of enzymatic pre-treatment on bioaccessibility and extractability of seaweed proteins. Enzymatic pre-treatment of seaweed samples resulted in a three-fold increase ...

Fisheries operate under fluctuating environmental conditions, targeting fish stocks that appear in varying densities in different areas, often with abrupt and unexpected local changes. Physical conditions, markets and management regulations constrain vessels in different and varying ways. These factors all contribute to forming the fleet diversity we find in most fisheries. Here, a simulation model ...
