The effect of temperature, aerial exposure and disturbance on oxygen consumption in the lobster,Homarus gammarus(L.)

Relative Humidity Effects on Tolerance of the Kuruma Prawn Exposed to 14°C Air

“…There would be a build up of metabolic waste products in cluding dissolved CO2 and concomitant acid-base prob lems as a result of reduction in gas exchange capabilities as suggested in the case of crayfish and lobster. 1,14) High reductions in body weights were found after 28 h of aerial exposure at 73% R.H. The values measured in the present study are consistent with the previous finding (15.71%).4) Undoubtedly, the weight loss was due to evapo ration from the body surface.…”

Metabolic rates in hatchery-reared European lobster juveniles (Homarus gammarus L.)

“…Typical stress influenced respiration rate seems to be approximately twice the standard rate. The standard rate of European lobster within the size interval 230-600 g was found to be 0.73 mg O 2 /kg x min at 20°C [6] i.e. about half of the lowest rate found in this study for lobster of 208 g. The oxygen consumption ranges were large, 1:8 to 1:3 within the same size groups, and the fluctuations may be due to diurnal rhythm and peak at feeding.…”

Feeding, Respiration, and Aerial Exposure in a Scavenging Cirolanid Isopod From New Zealand

“…Aerial exposure may be a significant stress factor for crustaceans, such as N. rossi, from low-shore and subtidal habitats. For example, in lobsters, O, reductions of 43 and 71% occurred following aerial exposure at temperatures of 15 and 20°C, respectively (Whiteley et al, 1991). However, the ability of N. rossi to respire in air was similar to that of the isopod Naesa bider2tata (Adams) from the mid-shore level and better than that of the high-shore species Campecopea hirsuta (Montagu) (see Wieser, 1963).…”
