The Neglected Marine Fungi, Sensu stricto, and Their Isolation for Natural Products’ Discovery
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-10)Despite the rapid development of molecular techniques relevant for natural product research, culture isolates remain the primary source from which natural products chemists discover and obtain new molecules from microbial sources. Techniques for obtaining and identifying microbial isolates (such as filamentous fungi) are thus of crucial importance for a successful natural products’ discovery program. ... -
Quantification of bell-shaped size selectivity in shrimp trawl fisheries using square mesh panels and a sorting cone after a Nordmøre grid
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-12)Shrimp trawlers in the Barents Sea use a Nordmøre sorting grid ahead of a small-mesh codend to avoid bycatch while catching shrimps efficiently. However, small fish can still pass through the grid to enter the codend, which increases their risk of being retained. In this study, we quantified the selectivity of a standard Nordmøre grid used together with one of two different codend designs, namely a ... -
Trained Innate Immunity of Fish Is a Viable Approach in Larval Aquaculture
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-25)The general understanding has been that only adaptive immunity is capable of immunological memory, but this concept has been challenged in recent years by studies showing that innate immune systems can mount resistance to reinfection—as the innate immune system can adapt its function following an insult. Innate immune training offers an attractive approach in intensive fish larval rearing, especially ... -
