To obtain baseline information on the size distribution of individuals in the population and reproductive features of sea star Asterias amurensis, monthly surveys of the population were carried out from May to December 2010 and March to May 2015 in coastal waters off Yantai, China. Spawning period was predicted by gonad and pyloric caeca indices as well as anatomical and histological methods. In the A. amurensis population, both large individuals（〉143 mm） and small ones（〈42 mm） were present in all sampling months. The population size structure was driven by the appearance of big cohorts of individuals less than 55 mm from May to August. The appearance of small individuals in all months suggested a prolonged spawning period at other sites in this bay or sea stars growing slowly because of food shortage. An arm length is a good predictor to wet body weight for ***. The development of gonad was relative slow from May to September but rapidly reached a peak of20.95 in October 2010, and then dropped remarkably, indicating its spawning lasted from October to *** same phenomenon was found from March to May 2015, suggesting another spawning during March to May,which was also verified by the results of histologic analysis on ovary. The gonad index（GI） and pyloric caeca index（PCI） tended to show a negative relationship. Due to the poor food availability, the reproductive characteristics of sea star were most likely affected by the shellfish mariculturein Yantai coastal waters.

Journal of Oceanology and limnology 2019年第5期37卷 1714-1725页

Sea cucumber Apostichopus japonicus is an important marine economic species in Asian countries due to its profound nutritional and medicinal value. So far, with the rapid development of intensifi ed artifi cial aquaculture of sea cucumbers, the use of antibiotics is still an inexpensive and dispensable way to treat pathogenic infections, especially during the nursery phase. However, there is little information on the eff ects of antibiotics on the intestinal microbiota of sea cucumber. Therefore an Illumina based sequencing method was used to examine the intestinal bacterial composition of juvenile A . japonicas following diets with three typical antibiotics (tetracycline, erythromycin, and norfl oxacin) under 15, 30, and 45 d. The fi ndings reveal that diff erent antibiotics have distinct eff ects on the growth performance of juvenile sea cucumbers. However, the richness and diversity of microbiota were barely aff ected by antibiotics but the community composition alterations indicated that the three antibiotics exhibited their respective patterns of reshaping the intestinal bacteria of juvenile sea cucumbers. In common, the abundance of some sensitive genera with helpful functions, such as Thalassotalea , Shewanella , Sulfi tobacter , and Halomonas decreased signifi cantly with exposure to antibiotics and the abundance of multiple potential pathogenic- and suspected antibiotic-resistant microorganisms like Arcobacter , Leucothrix , and Clostridium_sensu_stricto_1 was found increased signifi cantly in the antibiotic groups. These results suggest that low doses of antibiotics could aff ect the composition of the intestinal microbiota of sea cucumbers and might increase the risk of infection of the hosts. This study could help us to explore how antibacterial compounds modify the gut microbiota of sea cucumbers and provide theoretical guidance in hatchery management by scientifi c antibiotic use in sea cucumber mariculture.

Death of Prorocentrum donghaiense May Be a Programmed Autolysis

引用

Journal of Ocean University of China 2008年第3期7卷 276-280页

作者： YANG Guanpin liU Yongjian li bingjun College of Marine life Sciences Ocean University of China Qingdao 266003 P. R. China College of Oceanography Yantai University Yantai 264005 P. R. China

Prorocentrum donghaiense,one of the dinoflagellate,has continuously caused large scale red tides along the Chinese coast in recent years. These red tides have brought tremendous loss to the local economy and serious impacts to the local environment. Unfortunately,little was known about the mechanism of the fast appearance and extinction of the red tide caused by this alga. In this study,the full-length cDNA of a caspase encoding gene of P. donghaiense was cloned and characterized,and the transcription of this gene during the senescence of the alga was semi-quantitatively determined. The cDNA was 520 bp in length. It contained a 258 bp open reading frame(ORF) which encoded a peptide of 85 amino acids. The amount of transcripts of the caspase encoding gene increased with the senescence of P. donghaiense and started to decrease gradually when the autolysis of P. donghaiense cells took place. We proposed that the death of P. donghaiense may be a caspase mediated programmed autolysis.

Analysis of the Influence Factors of Grain Supply-Demand Gap in China

引用

Agricultural Sciences 2018年第7期9卷 901-909页

作者： bingjun li Weiming Yang College of Information and Management Science Henan Agricultural University Zhengzhou China

Based on the analysis of the grain supply and demand gap’s current situation in China, this paper establishes an indicator system for the influence factors of grain supply and demand gap. Then this paper calculates the correlation degree between the main grain varieties’ supply and demand gap and its influence factors. The results show that sown area and unit yield have the greatest impact on wheat supply and demand gap;per capita disposable income and unit yield have the greatest impact on corn supply and demand gap;per capita disposable income and agricultural mechanization level have the greatest impact on the supply and demand gap of soybean and rice. From the analysis results, we can obtain the difference between the factors affecting the grain supply and demand gap, and provide a certain theoretical basis and new ideas for the balance of grain supply and demand in China.
