At 20°C, the normally buried <i>C. crangon</i> emerges from the sand at a P<sub>w</sub>O<sub>2</sub> of 40 to 50 % saturation (20 %o S); at 9°C the emersion response occurs at P<sub>w</sub>O<sub>2</sub> 20 %. A swimming reaction was always noted at P<sub>w</sub>O<sub>2</sub> 30 to 40 % (20 %o S; 20°C). Regardless of salinity, survival was high down to P<sub>w</sub>O<sub>2</sub> 30 %. LT<sub>50</sub>, was strongly dependent on <sub>w</sub>O<sub>2</sub> and salinity; thus at 10 %. S, <sub>w</sub>O<sub>2</sub> 10 %: LT<sub>50</sub> = 4.5 h; at 20 %o S. <sub>w</sub>O<sub>2</sub> 10 %: LTSo = 6 h; at 10 %. S, <sub>w</sub>O<sub>2</sub> 20 %: LT<sub>50</sub> = > 150 h. Circulating lactate was accumulated only at <sub>w</sub>O<sub>2</sub> 10 % saturation or lower. Normoxic lactate levels were ca 10 mg 100 ml<sup>-1</sup> and increased in <sub>w</sub>O<sub>2</sub> less than 10 % to 80 to 100 mg 100 ml<sup>-1</sup> after 3 to 4 h. <i>C. crangon</i> will die quickly at this P<sub>w</sub>O<sub>2</sub>, unless higher oxygen tensions prevail rapidly. Return to normoxic conditions caused circulating lactate to be re-oxidised to normoxic levels within 5 to 6 h. When <i>C. crangon</i> was forced to swim in different P<sub>w</sub>O<sub>2</sub> for up to 2 h the circulating lactate remained, regardless of the P<sub>w</sub>O<sub>2</sub> (100 to 40 % sat.) at norrnoxic levels. Oxygen consumption (MO<sub>2</sub>) rose to varying degrees (5 to 70 % of routine MO<sub>2</sub>) when <i>C. crangon</i> was forced to swim for 2 h. No sign of oxygen debt was found after a swimming period. Due to a higher MO<sub>2</sub> when exposed to <sub>w</sub>O<sub>2</sub> of 40 to 50 %, swimming MO<sub>2</sub> under these conditions rose only 10 to 15 %. During escape reactions <i>C. crangon</i> used its abdominal muscle, but after ca 15 contractions that muscle showed signs of fatigue. No increase in circulating lactate was found after such escape reactions. MO<sub>2</sub> under escape reactions increased up to 211 % of routine MO<sub>2</sub> at normoxic <sub>w</sub>O<sub>2</sub>. Here also the MO<sub>2</sub> returned quickly to routine levels without any signs of oxygen debt.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Behaviour, tolerance and anaerobic metabolism under hypoxia in the brackish-water shrimp <i>Crangon crangon</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-20 01:31:49.370319","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1986,"MonPub":null,"DateUpdate":"2009-04-24","DateCreate":"2009-04-24","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1986F137500016","VABBcode":null,"OpenAcc":1,"DOI":"10.3354/meps034125"},"refs":null,"anarec":{"AnaID":134252,"PubliDate":1986,"Pagination":"125-132","XtraPublOfAnaID":null,"ISBN":null,"Volume":"34","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43354,"SerRR":"Marine Ecology Progress Series.
