[Spatial pattern in larval distribution, settlement and growth of Crassostrea sikamea in Xiangshan Bay, Zhejiang Province, China].

The migration and settlement of oyster larvae significantly affect the distribution, recruitment, establishment and ecological services of oyster populations. We investigated the variations of Crassostrea sikamea larvae abundances between the two water layers and between the two experimental sites (seed bed and spawning bed) in Xiangshan Bay within a tidal cycle (9 sampling times), and explored the spatial patterns in larval settlement and spat growth at three intertidal zones (top, T; middle, M and bottom, B) of both experimental sites by a field settlement experiment. At the seed bed and spawning bed, oyster larvae abundance at the surface water significantly changed with sampling time.

A modified method to detect the phagocytic ability of eosinophilic and basophilic haemocytes in the oyster Crassostrea plicatula.

The immune defence system of bivalve species largely depends on haemocytes. Haemocytes are generally classified as hyalinocytes (H) or granulocytes (G), and each cell type is further sub-classified as eosinophilic (E) or basophilic (B) haemocytes. Until recently, research on eosinophilic and basophilic haemocytes has primarily focused on their morphologies, dye affinities and intracellular components.

Role of living environments in the accumulation characteristics of heavy metals in fishes and crabs in the Yangtze River Estuary, China.

Correlation of heavy metals in the tissues of typical organisms (i.e., fishes and crabs) and those in their living environments (i.

[Purification function and ecological services value of Crassostrea sp. in Yangtze River estuary].

Oyster reef ecosystem is a natural decontamination plant of estuarine environment. This paper analyzed the bioaccumulation of heavy metals by Crassostrea sp. population at the dams of Yangtze River estuary, with its purification capacity and ecological services value assessed.

Prediction and setup of phytoplankton statistical model of Qiandaohu Lake.

This research considers the mathematical relationship between concentration of Chla and seven environmental factors, i.e. Lake water temperature (T), Secci-depth (SD), pH, DO, CODMn, Total Nitrogen (TN), Total Phosphorus (TP).

[Advances in research of biological purification of eutrophic water body].

Eutrophication is a global problem, and the key of its controlling is to manipulate the structure of aquatic ecosystem, to recover the function of natural, healthy and stable aquatic ecosystem, and to improve the biological purification capability of eutrophic water body. Aquatic higher plant and vegetation is the most important primary producer in aquatic ecosystem, because of its large individual, long life cycle, and strong capability of absorbing nutrients. Maintaining and restoring a certain amount of aquatic plant could restrain the growth of phytoplankton, improve the biodiversity of aquatic ecosystem, and stabilize its structure.
