Increases in circulating glucose and lactate took place in oxygen tensions P<sub>w</sub>O<sub>2</sub> = < 30 Torr only, indicating aerobic metabolism down to this oxygen tension. In moderate hypoxia, <i>N. norvegicus</i> synthesised haemocyanin; in more severe hypoxia some haemocyanin catabolism occurred. Mean normoxic blood ammonia concentration was 130 mu M NH<sub>4</sub><sup>+</sup>/l with large individual variation. Blood ammonia levels decreased with time in both normoxia and hypoxia showing a lowered metabolic rate over the experimental period. Mean ammonia excretion rate was 0.16 mu M NH<sub>4</sub><sup>+</sup> g/wet wt/hr under normoxia.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Aspects of blood physiology and ammonia excretion in <i>Nephrops norvegicus</i> under hypoxia","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-04 01:31:01.336489","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1990,"MonPub":null,"DateUpdate":"2009-06-11","DateCreate":"2009-06-11","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1990EB15200009","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/0300-9629(90)90721-4"},"refs":null,"anarec":{"AnaID":137410,"PubliDate":1990,"Pagination":"51-55","XtraPublOfAnaID":null,"ISBN":null,"Volume":"97","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42580,"SerRR":"Comparative Biochemistry and Physiology.
