Summary: | 10 páginas, 3 figuras Growth in developing turbot larvae can be expressed independently of temperature when using effective day-degrees (D8) as an index of development. The calculation of D8 is based on the eff eff principle of thermal summation whereby the rate of development is linearly related to the ambient temperature above a species-specific threshold temperature (T ) at which development is 0 theoretically arrested. The T for turbot embryos is 5.38C. The increase in wet body mass of 0 developing turbot larvae at 14, 18, and 228C can be aligned into a single exponential relationship regardless of incubation temperature when using D8 as the index of development. Previous eff attempts to relate physiological processes in poikilothermic animals, including fish, to incubation temperature are discussed. The study was financially supported by the Comisión Interministerial de Ciencia y Tecnología (CICYT, Spain) (Project AGF92-0185). Peer reviewed |
