Respiration rates and metabolic demands of Aurelia aurita in Tokyo Bay [Japan] with special reference to large medusae
2006
Ishii, H.(Tokyo Univ. of Marine Science and Technology (Japan)) | Tanaka, F.
The respiration rate of large medusae (11-24 cm bell diameter, 2-17 g dry weight) and their metabolic demand were estimated under laboratory conditions. The respiration rate (R; mL O2/ind/h) was defined as a function of water temperature (T; deg C) and body dry weight (W; g/ind) according to the equation, R=10sup(0.117T-3.1)Wsup(1.093). The weight specific daily carbon demand of medusae, including respiration and growth, in spring, summer, and autumn was 5.74, 17.6, and 7.27% of body carbon weight, respectively; and these were compared with the weight specific daily ration in specimens from the same area of Tokyo Bay.
