简介:Thisstudywasconductedtoevaluatethecriticalthermalmaximum(CTMax),theroutinemetabolismrate(MO2)andthelimitingoxygensaturation(LOS)ofthreesalmonidswithfourdifferentbodyweightsrangingfrom16gto131g.TheCTMaxwasestimatedatthreedifferentheatingratesincluding0.5℃min^-1,1℃h^-1and2℃d^-1.ResultsshowedthattheCTMaxofmapletrout(Oncorhynchusmykiss)wasthehighest,whichwasfollowedbysteelheadtrout(O.mykiss)andAtlanticsalmon(Salmonsalar).TheCTMaxofthesalmonidfishdecreasedwiththeincrementofbodyweight,andwassignificantlyinfluencedbytheheatingrate.TheMO2ofthesalmonidfishincreasedwiththeincrementoftemperature,anddecreasedwiththeincrementofbodyweight.Suffocationpointsofthefishdecreasedwithincreasingbodyweightandtemperature.SteelheadtroutwasmoretoleranttohypoxiathanmapletroutandAtlanticsalmon,whiletheMO2ofAtlanticsalmonwasthehighestamongthesethreesalmonids.TheLOSofthefishgenerallyhadapositivetrendwithtemperatureandbodyweight,andtheLOSofsteelheadtroutwassignificantlylowerthanthatofmapletroutandAtlanticsalmon.Inconclusion,mapletroutwasthemosttolerantkindtohightemperature,whilesteelheadtroutwasthemosttoleranttohypoxiaamongthreekindsofsalmonids.Moreover,theabilitiestotoleratehighertemperatureofthreesalmonidswereaffectedbytheirbodyweightandtheheatingrate,whiletheabilitiestotoleratehypoxiawereinfluencedbytheirbodyweightandthewatertemperature.
