The striped trumpeter (Latris lineata) is a promising new candidate for diversification of aquaculture in temperate regions of Australasia. Striped trumpeter is also of scientific interest due to an unusually prolonged post-larval phase. The research aimed to identify the optimal temperature for rearing post-larval striped trumpeter approaching metamorphosis. Three-hundred-day-old post-hatch post-larvae (12.10.2 g, 114.00.5 mm, meanSE) were reared at 12, 14, 16 and 18 C, over 84 days. Survival, growth and metamorphosis into juveniles were recorded every 21 days. Fish were fed to apparent satiation and reared in oxygen saturated water (95.92.6%). At 14 C, fish exhibited the best growth, had significantly higher lipid content and the majority (N90%) of the population metamorphosed into juveniles. The performance of fish reared at 16 C was similar to those at 14 C but the carcass had a significantly higher protein content and a significantly smaller proportion of the population (66.23.0%) metamorphosed into juveniles. A specific growth rate model showed that growth was highest at 14.4 C. At 12 C, fish showed the highest food conversion efficiency and all of the fish metamorphosed into juveniles. At 18 C, fish showed the lowest growth, metamorphosis, and protein and energy retention. This is the first study on the effects of temperature on growth and development of striped trumpeter post-larvae. The results have important implications for aquaculture and fisheries management of striped trumpeter, in particular the rearing of post-larvae in hatcheries, timing of stocking into sea cages especially prior to metamorphosis, and for wild stock recruitment models.
