“…ecosystem and human health [2,3] . Meanwhile, heavy metals can be part of the sediments during the adsorption process, and since the sediments are only slightly affected by hydrological factors, it's easy for heavy metals to store up in the sediments and pollute the benthic environment [4,5] . In terms of the heavy metal pollution in the Liaodong Bay, a series of researches and studies have been carried out, and through which people finally have a certain understanding of the heavy metal pollution in this area [6,7,8,9] .…”

Distribution of heavy metals (Hg, Cu, Pb, Zn, Cd and Cr) in the seawater and sediments were studied based on data from two oceanographic surveys carried out in Liaodong Bay in May and October 2016. The results showed that the values of heavy metals in seawater represent a uniform distribution, while no trends were detected for spatial distribution. High values of heavy metals in sediment were generally distributed nearshore areas in October. Concentrations of Pb, Zn, Hg in seawater were higher than the national guideline values of Mar. sediment quality of China. Values of Cu, Zn, Cd and Hg were higher than the national guideline values of Mar. sediment quality of China in October, while quality was in good condition in May. Correlation analysis showed that TOC was mainly contributed for the variations of heavy metals. The potential ecological risk analysis of heavy metals indicates that Hg, Cd and Cu should be listed as the priority contaminant metals in Liaodong Bay.

Tissue expression and stock variation of isozymes of stone flounder (Kareius bicoloratus) were analyzed with horizontal starch gel electrophoresis. For the fourteen enzymes assayed, 31 loci were recorded. The results indicated that all the isozymes examined were obviously tissue-specific. The expressions of SOD*, GDH*, G3PDH-2* and ADH-2* were detected only in liver, SDH-1*, MDH-1* and ADH-1* only in muscle, and LDH-B* and LDH-C* only in eyes. In comparison, MDH-2*, GPI-3* and SDH-2* were detected in all tissues examined. Other loci examined were detected in a variety of tissues. Muscle and liver were selected to detect the isozyme variation of the two geographic stocks of Qingdao and Weihai, Shandong Province, China. The percentages of polymorphic loci (P 0.99 ) were 29.17% and 25.00%, the observed heterozygosities (H 0 ) were 0.028 ± 0.014 and 0.040 ± 0.019, and the expected heterozygosities (He) were 0.039 ± 0.017 and 0.052 ± 0.022 in Qingdao and Weihai stock, respectively. The coefficient of gene differentiation (F st ) and genetic distance (D) between the two stocks was 0.012 and 0.0011, respectively, indicating that the genetic differentiation is low between them. Compared with other species of Pleuronectiformes, both the percentage of polymorphic loci and the mean heterozygosity of K. bicoloratus were at a middle level.

Isozyme analysis of spotted halibut Verasper variegatus temminck et schlegel

Abstract: To investigate the tissue-specificities of isozymes and the genetic structure of wild spotted halibut ( Verasper variegatus) population, horizontal starch gel electrophoresis was performed on 45 individuals collected in part of the Yellow Sea.
