This study aimed to investigate the effect of alternating feeding (Alt) compared with control being fed every day (Con) in the on-growth face of Atlantic cod. Individually marked fish (198 and 98 in the Con and Alt groups, respectively) was sampled f

The study was designed to investigate the effect of four cycles of 5 weeks starvation followed by 10-week refeeding compared with daily feeding under either natural photoperiod or continuous light (LL) regime on body composition and flesh quality in

Maturing male and female Atlantic salmon (Salmo salar L.) were held under three temperature regimes for 10 weeks between September and December: warm (constant 14-16 °C), ambient (decreasing from 11 to 5 °C), and cold (decreasing from 7 to 3 °C).

Feeding preferences of juvenile lumpfish reared together with Atlantic salmon in sea pens were assessed. Juvenile lumpfish, initial mean (± SE) weight of 54.0 ± 0.9 g, were reared in small sea cages (125 m3, 5 × 5 × 5 m) together with Atlantic sa

The lumpfish (Cyclopterus lumpus L.) has recently become relevant for aquaculture due to its appetite for the ectoparasitic copepod, the sea louse (Lepeophtherius salmonis Kroyer). In order to determine the effect of temperature on growth properties

This study assessed the use of different types of substrates for lumpfish in sea pens. Observations were recorded in the early morning before first light, and the number of lumpfish attached to each surface type was recorded. The substrate was remove

Growth and performance of Atlantic salmon in the presence of lumpfish were assessed in two studies. In the first study, six sea cages (5 × 5 × 5 m) were each stocked with 120 Atlantic salmon with a mean (± SD) weight of 619 (± 49) g and reared fo

The behaviour of lumpfish, Cyclopterus lumpus L., in sea pens, with and without Atlantic salmon, Salmo salar L., present, was assessed by underwater camera technology. Behaviour was classified by recording the principal activity of individual fish fo

The salmon louse is an ectoparasitic copepod that causes major economic losses in the Atlantic salmon aquaculture industry. To assess the efficacy of lumpfish grazing on attached sea lice on Atlantic salmon, six sea cages (5 × 5 × 5 m) were each st

Different feeding regimes (fasting/re-feeding and reduced feeding) were tested in a 131 day trial with 1400 juvenile (mean ± SE, 132 g ± 1) Atlantic cod ( Gadus morhua ) in order to see if a compensatory growth response could be elicited, and if hy
