【 摘 要 】

There have beennumerous studiesinwhichthereproductivecycles ofteleosts have beencorrelated with either environmentalcycles or associated physiological cycles, orboth. Suchcorrelationisseldom accurately achieved; usuallybecause thereproductive cycleofthespecies concernedis lax,sometimesbecauseonly one ortwofactorsof anintegratedwhole were examined.Thepowan ofLoch Lomond, Coregonus lavaretus(L. ) (Teleostei,Salmoniformes) is thesubject of along-termstudyinvestigating itsgrowth,in particular reproduction.Thisraceisafreshwaterglacialrelictformof aborealgroup, andthus hasan exceptionally strictlytimesreproductive cycle.It thusrepresents anidealsubject forcyclical studies.This thesis investigates therelationship betweenlipidstorageandthereproductive cycle andtherole ofthyroidgland.
