To gain a better understanding the inference of the Water and Sediment Discharge Regulation (WSDR) project on the species composition and distribution of ichthyoplankton in the estuary and adjacent area, we investigated surveys at 13 stations in June and July. The results show that, 1280 eggs, 5866 larvae are collected, the dominant fish eggs are Dotted gizzard shad (Konosiru spunctatus), silver sillago (Sillag osihama), Joyner's tonguesole (Cynoglossus joyneri); the dominant larvae are Japanese anchovy (Engraulis japonicas), Tapertail anchovy (Coilia mystus) and the gobiidae fishes. The numbers of species (S), abundance (N), Margalef richness index (D), Shannon-Wiener diversity index (H') and Pielou's evenness index (J') were calculated. The result showed that the values of S, N, H', D are low, but the value of J' is high in the middle of WSDR. © 2013 Taylor & Francis Group.

To understand the spatiotemporal distribution of harmful algal bloom (HAB) is the basis for the monitoring and prevention management of this disaster. In this paper, the data of 76 HAB events happened in Shandong coastal waters from 1990 to 2010 were analyzed, showing that the frequency of the disaster's events could be evidently divided into four phases, and the peaks presented an increasing trend. The area this disaster happened appeared as periodic inverted U curve. The HAB happened frequently from May to October in each year, and the HAB events happened in August accounted for more than 30% of the total. Most of the events happened in Laizhou Bay, Qingdao coast, and Beihuangcheng waters, and the frequency of the events was the highest in Sishili Bay. The disaster caused by Noctiluca scintillans and Phaeocystis globosa occupied the largest area, and the frequency of the disaster caused by Noctiluca scintillans and Gymnodinium sanguineum was the highest. The early warning management of the HAB in Shandong Province was introduced from the aspects of monitoring system, forecasting methods, and management mechanism, and the prevention and control measures were proposed based on this study. It was suggested that the pollution control and ecological remediation could be the fundamental solution.
