First Time

The red tide of Chattonella marina (Subrahmanyan) Hara & Chihara occurred in Rushan coast, Shandong Peninsula, China, in August 2008. Based on the four cruises of routine monitoring and four cruises of monitoring of the red tide in Rushan, the process of the red tide and possible mechanism were analyzed. During the bloom, the maximum area of the red tide was about 100 km2; the maximum average cell abundance of C. marina reached 1.46×106 cells/L; surface water temper-ature ranged between 26.1 °C and 27.2 °C, and salinity between 26.6 ‰ and 30.3 ‰. The material released from the decayed green tide species Ulva prolifera could provide a chance for the bloom of C. marina, combined the optimum sea temperature, light and nutrient condition. It was the first time to link a red tide event with the consequence of the green tide in Yellow Sea, which could give an attention on our future monitoring and management.

The marine raphidophyte Chattonella marina complex forms red tides, causing heavy mortalities of aquacultured fishes in temperate coastal waters worldwide. The mechanism for Chattonella fish mortality remains unresolved. Although several toxic chemicals have been proposed as responsible for fish mortality, the cause is still unclear. In this study, we performed toxicity bioassays with red sea bream and yellowtail. We also measured biological parameters potentially related to ichthyotoxicity, such as cell size, superoxide (O2•−) production, and compositions of fatty acids and sugars, in up to eight Chattonella strains to investigate possible correlations with toxicity. There were significant differences in moribundity rates of fish and in all biological parameters among strains. One strain displayed no ichthyotoxicity even at high cell densities. Strains were categorized into three groups based on cell length, but this classification did not significantly correlate with ichthyotoxicity. O2•− production differed by a factor of more than 13 between strains at the late exponential growth phase. O2•− production was significantly correlated with ichthyotoxicity. Differences in fatty acid and sugar contents were not related to ichthyotoxicity. Our study supports the hypothesis that superoxide can directly or indirectly play an important role in the Chattonella-related mortality of aquacultured fishes.
