The effect of temperature and fish size on growth, feed intake, food conversion efficiency and stomach evacuation rate of Atlantic salmon post-smolts

The effect of temperature and fish size on growth of juvenile lumpfish (Cyclopterus lumpus L.)

“…The minimum feed conversion efficiency (FCE) was very high in all experiments (S-AMB = 2.68 and S13 = 2.96 , TABLE VIII, Appendix II ), far superior to that of juvenile cod (1.18 -1.35 %) (Imsland et al 2005), turbot (0.82 -1.21 %) (Imsland et al 2000;Imsland et al 2007a), spotted wolffish (1.11 -1.37 %) (Imsland et al 2006;Magnussen et al 2008), Atlantic salmon (0.77 -1.35 %) (Handeland et al 2008;Björnsson & Jönsson 2012) when reared close to T opt FCE in the same size range. This represents a very significant cost benefit for lumpfish farming, as feed costs are the greatest single cost factor in aquaculture.…”

Effects of temperature and feeding frequency on ingestion and growth for rare minnow

“…Temperature and feeding frequency affect the digestive rate, gastric evacuation rate (GER) and evacuation time [55][56][57][58][59]. Previous studies have taken gastric evacuation rate as a determinant in decisions regarding feeding regimes, setting feeding intervals to match the evacuation time [23,24].…”

“…The digestive rate of fish is influenced by weight, meal size, dietary composition and energy [23,57]. For experimental fish, the environmental factors and feeding regime should be standardized to satisfy the requirements for development and welfare [63,64].…”

Differential changes in growth patterns of anadromous brown trout and Atlantic salmon from the River Etneelva over a 25-year period

“…Atlantic salmon parr have their maximum growth at higher temperatures than anadromous trout parr, and are also better at converting food to body mass at high temperatures . Depending on the size of the Atlantic salmon post-smolt, optimal temperatures for growth may be in the range of 12.8Á148C (Handeland et al 2008). As there seems to be a positive relationship between post-smolt growth and the return rate of SW Atlantic salmon (Friedland et al 2000), temperature may also indirectly affect survival.…”
