In this study, the bacterial community structures in samples of ballast water collected from a ship from Singapore and of local sea water collected from Xiamen Port were compared using restriction fragment length polymorphism (RFLP) and 16S rDNA sequence analysis. Except for dominant a-Proteobacteria that are common to both systems, the bacterial community structures of the two systems were quite different. Most of the clones derived from the different systems were grouped into different phylogenetic clusters, and the systems share only one common RFLP pattern. The ballast water, which is likely from clean offshore waters, contains sequences specific to aand c-Proteobacteria. Phylogenetic analysis revealed that the ballast water contained sequences belonging to attached bacteria and bacteria commonly found in the open sea, as well as many novel sequences. In addition, no known pathogenic bacteria were detected in the ballast water samples. Conversely, water samples from Xiamen Port were apparently affected by the near shore environments. Specifically, in addition to aand c-Proteobacteria, water from Xiamen Port contained band d-Proteobacteria, Synechococcus, Bacteroidetes and Actinobacteria, which are common in coastal environments. Additionally, four pathogenic bacterial sequences and one plasmid sequence of a potential red tide forming alga were detected in the water from Xiamen Port, which suggests that the local sea water is polluted. The results of this study can be used as background information to assess the risk associated with the introduction of non-indigenous species to local systems and to establish ballast water management systems.

We investigated the directed graph self similar sets under some weak overlapping condition. We get the multifractal decomposition formulas for these sets, i. e., dimK u a =DimK u a =f(a), wheref is the multifractal spectral function of the directed graph self similar measure, Especially, the results improve that of Edgar and Mauldin to the case which allows certain overlapping. Key words Hausdorff dimension - Hausdorff measure - multifractal decomposition CLC number O 211. 6 Foundation item: Supported by the National Natural Science Foundation of China (10371092) and the Foundation of Wuhan UniversityBiography: Zheng Shui-cao (1973-), male, Ph.

Genetic diversity of cultivated populations was investigated using assay of vertical slabpolyacrylamide gel electrophoresis in 4 species of shrimps, which were Penaeus japonicus, Penaeus monodon , Penaeus vannamei and Metapenaeus ensis, The results showed that the mean number of alle-les per locus (A) is 1.3±0.2, 1.3±0.1, 1.3±0.1 and 1.3 ±0.1 respectively; the percentage of polymorphic loci (P0.95) is 12.5, 6.7, 20 and 23.5 respectively; the expected heterozygosity (He) is 0.042±0.034,0.042±0.031, 0.094±0.042 and 0.097±0.047 respectively; and the observed heterozygosity (H0)is 0.029±0.024, 0.028±0.023,0.154±0.082 and 0.150±0.084 respectively. The difference of genetic diversity is obvious in 4 species of shrimps. The degree of genetic diversity is M. ensis > P. vannamei > P. japonicus > P. monodon. In short, the lower level of genetic diversity is estimated in 4 species of shrimps.

The genetic diversity and differentiation of 6 mud crab Scylla serrata populations from southeastern China are investigated using allozyme electrophoresis. The mean number of alleles per locus population is 1.3 ± 0.1; the percentage of polymorphic loci per population is 27.3; the observed heterozygosity ranges from (0.195±0.083) to ( 0.241±0.090) and the expected heterozygosity ranges from ( 0.105±0.043 ) to ( 0.131±0.047 ). The coefficient of gene differentiation among populations is low (Fst =0.032), indicating that only 3.2 % of the total genetic diversity comes from inter-population, while the remaining 96.8 % comes from intra-population differences. The genetic distance among populations is 0.000-0.008 (the average is 0.002). Gene flow among the populations is large (Nm = 7.56).Genetic structure is very similar among 6 Scylla serrata populations.

The halotolerance of phyllosoma larva of Chinese spiny lobster (Panulirus stimpsoni Holthuis) was experimentally studied in a man-made seawater of 13, 15, 19, 23, 27, 31, 35, 39, 43, 47 and 49 salinity. The experimental results showed that phyllosoma larve survived for 4~6 d with a rate of 25.0% to 47.5% if seawater salinity was increased or decreased gradually from 31 to 49 or to 13 respectively. In a range of 23 to 39 salinity, the phyllosoma larva grew, developed and metamorphosed normally, the metamorphosis rate of which in Stages II and III being 85% and 48% , respectively, when cultured in seawater of 31 salinity. It seems that some regular dispersion of larvae appeared in various salinities of seawater; In lower salinity, they mainly dispersed in the lower layer and in higher salinity,almost stayed in the upper and middle layers. Also, the results indicated that the phyllosoma larva of Chinese spiny lobster had a strong halotolerance to various salinities of seawater ranging from 15 to 47,in which 27 to 35 salinities were appropriate for larva growth and development.
