The effects of changing feeding frequency simultaneously with seawater transfer in Atlantic salmon Salmo salar L. smolt
The effects on group feed intake and growth performance of changing feeding frequency simultaneously with seawater transfer of Atlantic salmon Salmo salar were investigated. Two feeding regimes of one feed per day (1F) and eight feeds per day (8F) were compared for groups of Atlantic salmon in fresh...

n

P
< 0.05) lower feed intake immediately following transfer than 8F groups. However, groups that underwent a change in feeding frequency did not have significantly lower feed intake immediately following transfer than those kept on the pre-transfer feeding regime. During the freshwater phase, overall mean feed intake of 8F groups was significantly greater than 1F groups, whilst there was no significant difference in mean feed intake for any of the treatments during the seawater phase. Growth was better in groups fed 8F in freshwater than those fed 1F in freshwater regardless of post-transfer feeding regime. There were no significant differences in growth depensation throughout the experiment, suggesting that there were no overall differences in hierarchy strength amongst treatments. The main finding of this experiment was that a single meal per day immediately following seawater transfer results in initially significantly lower feed intake than the higher feeding frequency regardless of pre-transfer feeding regime, consequently multiple daily feeds is the recommended feeding regime following seawater transfer.</description><identifier>ISSN: 0967-6120</identifier><identifier>EISSN: 1573-143X</identifier><identifier>DOI: 10.1007/s10499-011-9439-7</identifier><language>eng</language><publisher>Dordrecht: Springer Netherlands</publisher><subject>Biomedical and Life Sciences ; Experiments ; Feeding ; Feeds ; Fisheries ; Fresh water ; Freshwater & Marine Ecology ; Life Sciences ; Marine ; Marine conservation ; Meals ; Physiology ; Salmo salar ; Salmon ; Seawater ; Water quality ; Zoology</subject><ispartof>Aquaculture international, 2012-02, Vol.20 (1), p.29-40</ispartof><rights>Springer Science+Business Media B.V. 2011</rights><rights>Springer Science+Business Media B.V. 2012</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c487t-ae68149e9eed927790e4d6ca1814a2ff0d1406da8c40a0902a7c0937b356a2dd3</citedby><cites>FETCH-LOGICAL-c487t-ae68149e9eed927790e4d6ca1814a2ff0d1406da8c40a0902a7c0937b356a2dd3</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://link.springer.com/content/pdf/10.1007/s10499-011-9439-7$$EPDF$$P50$$Gspringer$$H</linktopdf><linktohtml>$$Uhttps://link.springer.com/10.1007/s10499-011-9439-7$$EHTML$$P50$$Gspringer$$H</linktohtml><link.rule.ids>314,776,780,27901,27902,41464,42533,51294</link.rule.ids></links><search><creatorcontrib>Flood, Matthew J.</creatorcontrib><creatorcontrib>John Purser, G.</creatorcontrib><creatorcontrib>Carter, Chris G.</creatorcontrib><title>The effects of changing feeding frequency simultaneously with seawater transfer in Atlantic salmon Salmo salar L. smolt</title><title>Aquaculture international</title><addtitle>Aquacult Int</addtitle><description>The effects on group feed intake and growth performance of changing feeding frequency simultaneously with seawater transfer of Atlantic salmon
