In an investigation into their potential ecological role(s), a group of mainly diterpene isonitriles, nine in total, isolated from the tropical marine sponge Cymbastela hooperi, and the sesquiterpene axisonitrile-3, isolated from the tropical marine sponge Acanthella kletra, were evaluated in a...
All marine operations have steps where the dynamic behavior changes in a transient way. In fact – it is the purpose of every operation to make changes. A process dominated by transient or highly non–linear response must be analyzed differently from a stationary case. The applicability and...
... Purpose - The purpose of this paper is to describe a new slaughter line for industrial slaughtering of salmonid fish. Traditionally, slaughtering of farmed salmonids salmon and rainbow trout was done manually by bleed cutting with knives. Using the new slaughter line that includes 3D machine vision...
A dynamical model for simulating growth of the brown macroalga Saccharina latissima is described. In addition to wet and dry weights, the model simulates carbon and nitrogen reserves, with variable C/N ratio. In effect, the model can be used to emulate seasonal changes in growth and composition of...
Hydrodynamic interaction effects between two ships going ahead in regular deepwater waves were numerically studied during typical maneuvers for ship-to-ship (STS) operations, such as lightering, replenishment, etc. Such maneuvers are usually classified as potentially hazardous situations, due to the...
Atlantic salmon (Salmo salar L.) experience periodic drops in dissolved oxygen (O2) inside aquaculture sea cages. In order to evaluate whether fish function or welfare is compromised during such drops in O2 (termed hypoxia), it is necessary to establish the limit for acceptable O2 reductions; the...
I dette prosjektet ble sammensetningen av fiskeslam fra ulike resirkuleringsanlegg for settefiskproduksjon undersøkt. Slam fra Smøla Klekkeri og Settefisk sitt anlegg på Smøla, Marine Harvest sitt anlegg på Tustna og Nofima sitt anlegg på Sunndalsøra ble analysert for innhold av tørrstoff...
