The Thermal Dependent Biology of Cultured Lummpfish (Cyclopterus lumpus Linnaeus 1758): Differences Due to Temperatures During Early Life and How Tolerance is Measured

Thus, we reared lumpfish embryos (eggs), larvae and juveniles under different temperature regimes, and measured their metabolic physiology and upper thermal limits, with the goal of better understanding their physiology and mitigating the effects of high summer water temperatures on their welfare. The specific incubation (egg) / rearing temperature combinations were 6°C / 9°C (normal production temperatures), 8.5°C / 9°C, 6-11°C / 9°C, 8.5°C / 9-11°C and 6-11°C / 9-11°C; with a range of temperatures indicating that fish were exposed to stochastic temperature changes.
