Synthetic oil spill dispersants have become essential in offshore oil spill response strategies. However, their use raises significant concerns regarding toxicity to phyto- and zooplankton and other marine organisms, especially in isolated and vulnerable areas such as the Arctic and shorelines. Sustainable alternatives may be developed by replacing the major active components of commercial dispersants ...

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 ...

High-fat diets (HFD) are harmful to fish health. Probiotics are commonly utilized to improve fish nutrition metabolism, immune response, and health. Nucleic acids of the probiotic bacterium can be hydrolyzed by nuclease to generate nucleotides. The present study aimed to evaluate the effects of stabilized fermentation product of nucleasetreated Cetobacterium somerae XMX-1 [XMX-1 (N)] on growth, ...

En ny teknologi for opptining av fisk gjør det mulig å gjenvinne fersk kvalitet dersom fisken er frosset helt fersk. Det muliggjør overføring av oversjøisk transport av laks og ørret fra fly til skip, noe som kan redusere de norske klimagassutslippene med anslagsvis 800.000 tonn.<p> <p>Tineteknologien er EU­patentert av det norskeide tyske selskapet Coolnova UG. Blodferske fiskeprodukter kan ...

ω-3 fatty acids (n-3 FA) have, since the 1970s, been associated with beneficial health effects. They are, however, prone to lipid peroxidation due to their many double bonds. Lipid peroxidation is a process that may lead to increased oxidative stress, a condition associated with adverse health effects. Recently, conflicting evidence regarding the health benefits of intake of n-3 from seafood or ...

The study of biological invasions has triggered the production of a diversity of concepts. The terminology has, however, often been applied inconsistently and inaccurately. This article lists and assesses the most commonly used terms and concepts in invasion ecology. In each case the most coherent definition and use is suggested.

I 2014 påla Miljødirektorat Finnfjord AS først å utarbeide et program for vannovervåking, og deretter gjennomføre dette, i vannforekomsten Finnfjord Indre. Endelig rapport ble sendt inn 29 februar 2016, og i en foreløpig tilbakemelding fra Miljødirektoratet i brev datert 4 april 2016 konkluderer de med at det er behov for en ny undersøkelse som ...
