Temperature is one of the most important environmental factors affecting marine life. It is of great significance for academic and industrial communities to understand its influence on the larval development and settlement of the acorn barnacle Amphibalanus reticulatus. In the present study, two experiments were carried out, one for the effect of temperature on the development of nauplii and the other for the settlement of cyprids. In Experiment Ⅰ, newly-hatched nauplii were reared at 12 °C, 18 °C, 24 °C, 30 °C, and 36 °C, respectively, fed by the alga Platymonas subcordiformis with initial concentration around 8.0×10 4 cells·mL-1. After 96 hours, the surviving individuals were counted and their developmental stages analysed. In Experiment Ⅱ, cyprids were maintained in the same temperature regimes as Experiment Ⅰ for 96 hours, but without providing algal food. The numbers of surviving individuals were recorded regularly as those that had settled. In Experiment Ⅰ, the larval survival rates were 99.0 % ± 1.2 % (12 °C), 95.0 % ± 4.8 % (18 °C), 92.0 % ± 2.8 % (24 °C), 80.0 % ± 10.6 % (30 °C), and 0 (36 °C), with the larvae developing fastest at 30 °C, followed by 24 °C, 18 °C and 12 °C, based on the larval proportions at various stages. In Experiment Ⅱ, the cypris survival rate was 100 % at all designated temperatures; and although settlement occurred over a wide range of temperature (18 ~ 36 °C), it was the highest at 30 °C reaching 84.5 % ± 12.1 %. The statistical analysis indicated that there were significant differences in larval development and settlement between the group at 30 °C and those at 12 °C, 18 °C and 24 °C. In general, it can be concluded that from 12 °C to 30 °C, the larval development and settlement were promoted by increasing temperature. Cyprids presented a better tolerance to high temperatures than nauplii. No nauplii survived at 36 °C and no cyprids settled at 12 °C. In considering the survival rate, development status and settlement percentage of the larvae, 18 ~ 30 °C should be the appropriate temperatures for larval development and settlement of the acorn barnacle A. reticulatus.
