Abstract Efficient sea‐lice control remains one of the most important challenges for salmon farming industry. The use wrasse (Labridae) as cleaner fish offers an alternative to medicines control, but tend become inactive in winter. Lumpfish ( Cyclopterus lumpus ) continue feed on at low temperatures, and commercial production has escalated from thousands 2010 well over 30 million juveniles deployed 2016. However, still relies capture wild broodstock, which may not be sustainable. To meet...
Growth rate of tagged juvenile turbot was significantly influenced by the interaction temperature and fish size. The results suggest optimum for growth in size range 25–75 g is between 16 19°C. Optimal decreased rapidly with increasing size, 13 16°C 100 turbot. Although individual rates varied highly at all times within treatments, significant rank correlations were maintained during experimental period. study confirms that exhibit ontogenetic variation optimum, which might partly explain...
The Atlantic salmon is extensively studied due to conservation concerns and its economic importance in aquaculture. However, a thorough report of their aerobic capacity throughout entire thermal niche has not been described. In this study, (∼450 g) were acclimated for four weeks at 3, 8, 13, 18 or 23°C, then tested large Brett-type swimming respirometer groups ten per trial. Both standard metabolic rate active continued increase with temperature, which resulted an scope that also increased...
ABSTRACT To assess the efficacy of lumpfish grazing on attached sea lice Atlantic salmon, six large-scale cages, (130 m circumference, 37,688 m3 volume) each stocked with approximately 200,000 salmon 0+ smolts, were a 4, 6 and 8% density (8000, 12,000 16,000, respectively) lumpfish. The cages without acted as controls. Sea infestation levels monitored weekly bi-weekly from October to 17 May subsequent year. Mortality rose decreasing temperatures around 0.8% week−1 did not vary between...
Sexual dimorphism in growth and maturation of individually tagged turbot (n= 421), Scophthalmus maximus Rafinesque, was studied a long-lasting (20 months) experiment with four temperature regimes. The influence onset puberty subsequent on evaluated. There were no initial size differences, but the final weight females larger than that males at all regimes, except lowest temperature. Surplus energy (sum increase somatic gonad weight) average greater from 8 months prior to first spawning....
Higher growth capacity and food conversion efficiency was observed in populations of juvenile halibut from high Hippoglossus hippoglossus compared lower latitudes. In addition, temperature adaptation shown by the optimum for Norwegian population (mean±S.E. 12·9±0·10 C) with Icelandic Canadian (14·2±0·2 13·9±0±30 C respectively), seems to occur. Overall data support hypothesis countergradient variation growth. These results have implications firstly selection focusing on performance culture;...
Studies on the incidence and etiology of acute pancreatitis show large regional differences. This study was performed to establish incidence, severity in population Bergen, Norway.A all patients with admitted Haukeland University Hospital over a 10-year period performed. Information obtained about number Deaconess Bergen.A total 978 admissions were recorded these two hospitals giving an 30.6 per 100,000. had 757 487 patients. Pancreatitis severe 20% (96/487) patients, more often males (25%)...
Growth rate of individually tagged juvenile halibut was influenced significantly by the interaction temperature and fish size. The results suggest an optimum for growth in size range 5–70 g between 12 15° C. Overall highest at 13° C (1·62% day −1 ). At c. 5 beginning experiment, 16° had (3·2% ), but reduced this as they grew bigger. 9 11°p C, rates were equal or only slightly lower during later stages while 6° showed overall (0·87% Optimal decreased rapidly with increasing size, indicating...
ABSTRACT Shear force and rigor mortis were used to evaluate the post‐mortem changes of muscle texture in Atlantic salmon (Salmo salar). The fish either stunned with carbon dioxide (CO 2 ), electricity, or percussion prior slaughter. pre‐mortem stress during CO stunning resulted an earlier onset resolution mortis, accelerated softening tissue as compared other methods. No significant differences, development shear force, seen between that electricity by percussion. Consequently can be for
Growth, feed conversion efficiency and frequencies of skeletal deformities were studied in juvenile Atlantic cod (Gadus morhua) that had been startfed on either rotifers (rotifer group) or zooplankton (zooplankton group). After metamorphosis, the fish reared at four constant temperatures (7, 10, 13, 16°C) moved successively from 16 to 13 10°C (T-step, average 13.2°C). The group a consistently higher growth rate all studied. Further, food intake (20%) ratio (1.65 vs. 1.31). In addition,...
