In this paper, a new species of Octopus (Octopoda, Cephalopoda) was found in the materialcollected from the south-east waters of China, named Octopus tankahkeeei sp. nov.. Type specimen Holotype Female DOXUC-M20, and paratype Male DOXUC-M30 were preserved in Department of Oceanography of Xiamen University.

The mariculture of Manila clam Ruditapes philippinarum have developed rapidly in northern China, especially in Shandong Province since middle of 1980's. Most of the seed of Manila clams cultured in the areas was from natural sea before 2000. Due to the rapid development of mariculture of Manila clam in recent years, the juveniles of Manila clam from the natural sea could not meet the

The present paper reports the preliminary study on the reproductive behavior and embryonic development of clam mactra chinensis philippi based on the results of pond breeding. Along the coastal areas of Shandong Peninsula, the clam's spawning period starts in June and ends in August, and the peak is between late July and early August. The fresh meat weight ratio is increased with the

To clarify cuttlefish phylogeny, cytochrome c oxidase subunit I (COI) gene and partial 16S rRNA gene were sequenced for members of 7 Sepioid sepecies and several outgroups. Several phylogenetic trees were built by the neighbor-joining method. The coleoids were obviously be divided into two main lineages, Octopoda and Decapoda (Sepioiden + Teuthoidea). The order Sepioidea, including the

The physiological responses of Chlamys farreri and Argopecten irradians concentricus to environmental stressors, such as increasing temperature, decreasing salinity and starvation were studied in the laboratory. The oxygen consumption rate(OCR) and ammonia excretion rate (AER) were chosen as physiological indictors. The OCR of small sized scallops was higher than that of the
转化生长因子-β(TGF-β)超家族通过调节细胞的增殖、分化、移行及凋亡而在脊椎动物发育过程中起重要的作用。SMADs是细胞质内TGF-β信号转导分子,它们可以将TGF-(信号直接从细胞膜转导入细胞核内。SMAD4是TGF-β信号转导过程中重要的中心介导分子。Samd4在胚胎发育过程中以及成体各组织器官中有广泛的表达,意味着Smad4在成体各组织器官的发育过程中可能具有非常重要的生理功能。Smad4基因的完全剔除导致小鼠在胚胎发育早期死亡(Yang X et al:PNAS,1998,95(7):3667),使得研究者很难分析这些基因在

Two subgenera, Pseudiberus and Platypetasus under Pseudiberus, are merged into one genus,namely Pseudiberus, based on the fact that the snails cannot be distinguished based on shell characters. On studying the type specimens housed in the Institute of Zoology, CAS, Platypetasus cixianensis is sunk as a synonym of Pseudiberus chentingensis. The possible causation for the differentiation of shells, between Cixian County population and Zhengding Population of the species,is discussed.

All-tripioids were produced by mating female diploids and male tetraploids in Pacific oyster,Crassostrea gigas Thunberg (referred to as DT groups), along with diploid controls using eggs from the same female diploids (referred to as DD groups). Tetrapioid brood stocks were introduced from USA with the help of the 4C Company. Upon arrival at the experiment sites, tetraploid brood stocks

The scallop Clampys farreri is the main cultured species over the coastal farming areas in the northern China Sea. In the current decade, the growth rate of C. farreri sharply declined because of high culture density and exhaustion of food supply. Mass mortality of this species occurred in most of the farming areas in the northern China Sea, especially during summer and autumn since 1997. The
