The stalked barnacle, Capitulum mitella, is a sessile pedunculate cirripede that inhabits the exposed rocky intertidal frame, distributing south coast of the Changjiang Estuary in China. C. mitella is widely used as food in Fujian, Zhejiang and Guangdong. Because of being highly valued fishery resource and its economic importance, C. mitella will be a new breeding variety with considerable potential and market prospect. Temperature and salinity are known to regulate embryonic development, growth, survival and duration of larvae in many marine invertebrates. The combined effects of temperature and salinity on embryonic development and larval growth of C. mitella were investigated under controlled laboratory conditions, which could provide insight into reference for culturing of C. mitella. Four temperature including 24, 27, 30℃ and 33℃ as well as three salinity including 28, 31 and 34 were selected. The results showed as follows. The embryonic development time was the shortest (144h ) at 33℃-28, and the longest (216 h) at 24℃-34, 24℃-31 of temperature and salinity. The embryonic hatching rate was the highest (100%) at 27℃-28, the lowest (52.1% ) at 33℃-34 of temperature and salinity. Temperature, salinity and their interaction had significant affects on embryonic hatching rate, but had not significant affects on embryonic development time. The optimum rearing condition of temperature and salinity for embryonic development was 27℃-28. The fastest larval development (Nauplius II to cypris stage) occurred at 30℃-31 of temperature and salinity (7 days) and 27℃ regardless of variation in salinity at this temperature (8 days). Nauplius duration lasted 11 days at 24℃-34 and 33℃-34. Larval survival rate was higher at temperature 27℃ for fixed levels of salinity, at salinity 31 for fixed levels of temperature. The maximum survival rate 1 and survival rate 2 were 990% and 90.7% respectively at 27℃-31 of temperature and salinity. Metamorphosis rate was higher at 27℃-28 (818%), 27℃-31 (73.7%) of temperature and salinity. When salinity was up to 34, larval survival rate and metamorphosis rate were very low or even zero. The factors of temperature, salinity had significant affects on larval survival rate and metamorphosis rate, with significant interaction between temperature and salinity on larval growth. Considering total nauplius duration, survival and metamorphosis, the optimal combination of temperature and salinity for the larval growth and development of C. mitella was at 27℃ and 31. Larvae of C. mitella to salinity and temperature was more sensitive than embryos. We assume that the different response to environmental factors between embryos and larvae of C. mitella is attributed to its reproductive characteristic and habitat.
