This study assessed the use of different types of substrates (450 g PVC, 130 g plastic) and water speed (5.0, 10 and 20 cm s−1) on growth and substrate selection in lumpfish. There were no differences between the percentages of fish attached to bot

To assess possible size effects of foraging of lumpfish and co-existence with Atlantic salmon with particular interest to the sea lice grazing efficiency, eight sea cages (5 × 5 × 5 m) were stocked with 150 Atlantic salmon with a mean (± SD) weigh

To investigate the possible family influence on sea lice grazing of lumpfish on Atlantic salmon, nine families of lumpfish (N = 360) with a mean (± SD) weight of 169.4 ± 8.3 g were distributed among nine sea cages (5 × 5 × 5 m) each stocked with

A series of studies were undertaken to determine the behavioural interactions between three different size classes (110, 70 and 32 g) of lumpfish, Cyclopterus lumpus L., and one size class (30 g) of goldsinny wrasse, Ctenolabrus rupestris L. The stud

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
