Shrimp community structure and influence of environmental variables in the East China Sea and Yellow Sea in spring.

Based on data collected from research vessel cruises performed in May 2020 off the East China Sea (ECS) and the southern Yellow Sea (YS) (26°30'-35°00' N, 120°30'-127°00' E), we analyzed the shrimp community and its relationships with environmental variables by using index of relative importance, biodiversity indices, and multivariate techniques. A total of 29 species were recorded, belonging to 11 families and 19 genera. The dominant species were Metapenaeopsis longirostris, Leptochela gracilis, Solenocera melantho, Crangon hakodatei, Parapenaeus fissuroides, Plesionika izumiae, and Trachypenaeus curvirostris, which together accounted for 82.9% of the total biomass and 90.8% of the total abundance of shrimps. Results of Cluster and NMDS analyses showed that three groups were identified for the shrimp community in the ECS and YS in spring, including group A (inshore of northern ECS and YS group), group B (offshore of northern ECS group) and group C (southern ECS group). ANOSIM and SIMPER analysis showed significant differences between group A and B, gourp A and C, and group B and C, with the dissimilarity of 92.2%, 95.8% and 91.6%, respectively. The typical species were T. curvirostris, C. hakodatei, L. gracilis and Palaemon gravieri in group A, and S. melantho in group B, and M. longirostris, P. fissuroides, P. izumiae and Solenocera alticarinata in group C. Significant differences were also detected in biomass, diversity index, species richness index and evenness index among groups, with significantly greater values in group C than those in A and B. Environmental variables and the substrate also displayed significant differences among groups. Results of canonical correspondence analysis showed that bottom temperature, bottom salinity, depth, and the substrate were the main environmental variables affecting spatial structure of shrimp community. Water mass characteristics and substrate type had important influences on the distribution of shrimp community in the ECS and YS in spring.

Niches and interspecific association of dominant shrimp species in the offshore waters of southern Zhejiang Province, China

Based on data from November of 2015 (autumn), February (winter), May (spring), and August (summer) of 2016 in the offshore waters of southern Zhejiang Province, the relationships between major shrimps species were examined by niche breadth, niche overlap, variance ratio, chi-square test, association coefficient and species pair co-occurrence percentage. The results showed that temporal niche breadth of Atypopenaeus stenodactylu was the largest, spatial niche breadth of Solenocera crassicornis was the largest, and A. stenodactylu had the largest spatio-temporal niche breadth. The temporal niche overlap between Parapenaeus fissuroides and Parapenaeopsis tenella was the highest. The spatial niche overlap between Solenocera koelbeli and Penaeus chinensis, P. fissuroides and Heterocarpoides laevicarina were the highest. The spatio-temporal niche overlap between S. koelbeli and P. chinensis was the highest. The analysis of variance ratio showed that the main shrimp species were significantly positively correlated. Positive correlation existed in 13 pairs (χ2≥3.841). Results from the association coefficient (AC) and co-occurrence percentage (PC) indicated that the interspecific association tended to be positive. Our results provide supports for exploring niche breadth and niche overlap of major shrimp species and improving niche differentiation.

Spatial pattern of benthic macroinvertebrate communities and their relationship with environmental variables on the East China Sea shelf

To detect the large-scale spatial pattern of the benthic macroinvertebrate communities and the relationship with their environment on the East China Sea shelf, forty sites were sampled for benthic macroinvertebrates and environmental variables during August and September 2015. A total of 12529 benthic macroinvertebrate individuals and 274 species were collected, with crustaceans being predominant, followed by mollusks. Four communities were identified by hierarchical agglomerative cluster (HAC) analysis and cross-verified by non-metric multidimensional scaling (NMDS) ordination: an Inshore community (IC); a Transitional community (TC); a Northern offshore community (NOC); and a Southern offshore community (SOC). Significant differences in their community structure were found by permutational multivariate analysis of variance (PERMANOVA). The indicator species varied among the four communities, with Solenocera crassicornis, Sternaspis scutata and Virgularia sp. dominating IC, Solenocera koelbeli, Trachysalambria curvirostris and Nitidotellina valtonis dominating TC, Parapenaeus fissuroides, Onustus exutus and Drachiella morum dominating NOC, and Heikeopsis japonica, Solenocera pectinulata and Actiniaria dominating SOC. Significant differences among communities were detected for species number (S), Margalef's index (d), Pielou's index (J′), Hill's number (N∞), total taxonomic distinctness (SΔ+), average phylogenetic diversity (Φ+), total phylogenetic diversity (SΦ+) and abundance through statistical analyses. The redundancy analysis (RDA) model revealed that turbidity, silicate and depth were significant environmental variables influencing the benthic macroinvertebrates. Variation partitioning (VPA) showed that water characteristics had a greater impact than sediment conditions on the distribution of benthic macroinvertebrates in the East China Sea.

Population distribution pattern intensity of Parapenaeus fissuroides Crosnier in the northeast Fujian sea

In this study, the population pattern intensity of Parapenaeus fissuroides Crosnier in the northeast Fujian sea area was investigated with the negative binomal parameters, average crowding degree and poly block indices. The Paper also further discusses the driving factors of the population pattern intensity. In spring, the population primarily consisted of small patches, population aggregation was low, and individual mean crowding was the lowest of the year. In summer, population aggregation and individual mean was highest. In fall, the population primarily consisted of a small number of large patches. In winter, population aggregation was the lowest. The zooplankton biomass (feed) and water temperature were the major factors affecting population aggregation.

We also discuss the factors that affect pattern intensity and ecological significance of the pattern intensity indices. The aim of the study was to explore new aspects in the protection of the fishery resources for P. fissuroides Crosnier. In spring, its population primarily consisted of twelve patches, which showed dispersed population distribution and the second smallest poly block index. The population in spring had the smallest mean crowding, the largest average distance between individuals, and the biggest diffusion coefficient compared to that in other seasons. In summer, the population mainly consisted of four patches with most concentrated population distribution. The biggest poly block index, biggest mean crowding, smallest average distance between individuals, and smallest diffusion coefficient were observed. In autumn, the population primarily consisted of five patches with moderately concentrated population distribution. The second largest poly block index and mean crowding as well as the second smallest average distance between the individual diffusion coefficient were explored. In winter, the population primarily consisted of fourteen patches with highly dispersed population distribution, the smallest poly block index, the second smallest mean crowding, and the second largest average distance between individuals and diffusion coefficient. The negative binomial parameter and Morisita index were employed to characterize the aggregation intensity. When the Morisita index is greater and the negative binomial parameter is smaller, the aggregation intensity is stronger, and vice versa. Mean crowding provided a more actual representation of the average individual crowding degree compared with the average density. Mean crowding reflected the average individual crowded degree. When mean crowding was large, the inter-specific competition was intense,and average distance between individuals was smallest. The poly block index revealed the constitution of the population patches. When the poly block index was big, the population primarily consisted of a few patches, and vice versa. The diffusion coefficient reflected the diffusion degree. The bigger the diffusion coefficient, the greater was the significant spread of the population. The food zooplankton was the major factor influencing the pattern intensity, and the inter-specific competition was the major factor mediating diffusion degree of the Parapenaeus fissuroides Crosnier in the sea area northeast of Fujian. In this study, the population distribution pattern intensity simplified the research of school behavior, which reflect the aggregation intensity, poly block, mean crowding, inter-specific competition degree, and diffusion degree to meet the school behavior inherent law. 参考文献 相似文献 引证文献

Growth pattern and longevity of Parapenaeus fissuroides Crosnier, 1985 (Decapoda, Penaeidae) in Kagoshima Bay, southern Japan

Parapenaeus fissuroides Crosnier, 1985 is an emergent fisheries shrimp resource in the benthic community of Kagoshima Bay. The growth pattern and longevity of P. fissuroides were estimated from monthly length-frequency distributions. Carapace length (CL) ranged from 7.7-27.1 mm in males and 6.4-36.1 mm in females. Both males and females were recruited during late autumn and winter. Growth was best described by Pauly & Gaschütz’s growth equation as for males and for females. Females grew faster and reached larger sizes than males of the same age group. The life-span of P. fissuroides was estimated to be around 2 years for males and 2.5 years for females.

Ovarian Maturation, Size at Sexual Maturity, and Spawning Season of Parapenaeus FissuroidesCrosnier, 1985 (Decapoda: Penaeidae)

Reproduction, including ovarian maturation, size at sexual maturity, and spawning season of Parapenaeus fissuroides Crosnier, 1985 (Decapoda: Penaeidae), were studied using females collected from Kagoshima Bay, Kyushu, Japan. The ovaries of individuals were examined by histological observations to estimate the degree of ovarian maturation. Ovarian maturity stages were classified into four categories based on the developmental stage of the most advanced oocytes in the ovary as follows: undeveloped, developing, nearly ripe, and ripe. The mature females were defined as those having nearly ripe or ripe ovaries containing cortical granules in the peripheral region of the oocytes. The gonadosomatic index (GSI) significantly increased with progress of ovarian maturation and most of the females with GSI ⩾ 6% were mature. The size at sexual maturity of female P. fissuroides was estimated to be 23.5 mm in carapace length. The spawning season of this species was estimated to last from July to February with a peak during October and November.

Seasonal and spatial variations of macro- and megabenthic community characteristics in two sections of the East China Sea

In spring and summer 2011, the macro- and megabenthic fauna in two sections of the East China Sea were investigated using an Agassiz net trawl to detect the seasonal and spatial variations of benthic community characteristics and the relation to environmental variables. The total number of species increased slightly from spring (131 species) to summer (133) whereas the percentage of Mollusca decreased significantly. The index of relative importance (IRI) indicated that the top five important species changed completely from spring to summer. Species number, abundance and biomass in summer were significantly higher than in spring, but no significant difference was observed among areas (coastal, transitional and oceanic areas, divided basically from inshore to offshore). Species richness (d), diversity (H') and evenness (J') showed no significant seasonal or spatial variations. Cluster analysis and nMDS ordination identified three benthic communities from inshore to offshore, corresponding to the three areas. Analysis of Similarity (ANOSIM) indicated the overall significant difference in community structure between seasons and among areas. K-dominance curves revealed the high intrinsic diversity in the offshore area. Canonical correspondence analysis showed that the coastal community was positively correlated to total nitrogen and total organic carbon in spring, but negatively in summer; oceanic community was positively correlated to total nitrogen and total organic carbon in both seasons. Species such as Coelorhynchus multispinulosus, Neobythites sivicola, Lepidotrigla alata, Solenocera melantho, Parapenaeus fissuroides, Oratosquilla gonypetes and Spiropagurus spiriger occurred exclusively in the offshore oceanic area and their presence may reflect the influence of the offshore Kuroshio Current.

PCR-based assessment of shellfish traceability and sustainability in international Mediterranean seafood markets

Two mitochondrial markers (cytochrome oxidase COI and 16S rDNA) were employed for species identification of commercial shellfish from two Mediterranean countries. New COI Barcodes were generated for six species: Pleoticus robustus, Metapenaeopsis barbata, Parapenaeus fissuroides, Hymenopenaeus debilis, Metapenaeus affinis and Sepia aculeata. Biodiversity of the seafood species analyzed was greater in Egypt, with nine crustacean and two cephalopod species found compared with only three crustaceans and three cephalopods in Spain. In total, 17.2% and 15.2% products were mislabeled in Egypt and Spain, respectively. Population decline is a problem for some of the substitute species. Others were exotic and/or invasive in exporters’ regions. This study offers the first comparable study of shellfish traceability in these Mediterranean markets. The PCR-based method used in this study proved to be reliable, effective and, therefore, could be employed for routine seafood analysis.

Identification of causative agents and species in shrimp implicated in a food poisoning case in Taiwan.

The possible causative agent and shrimp species involved in a bait shrimp poisoning case that occurred in northern Taiwan was determined. Because the patient's symptoms were similar to those caused by boric acid and slightly similar to those caused by sulfite, the concentrations of boric acid and sulfite (as sulfur dioxide) in the patient's vomitus and in shrimp collected from bait stores and markets were analyzed. The concentration of boric acid was 36.8 to 37.1 mg/g in the patient's vomitus, 1.4 to 3.8 mg/g in shrimp meats obtained from bait stores, and not detectable (less than 0.001 mg/g) in shrimp meat obtained from commercial markets. No significant differences in sulfur dioxide concentrations (0.067 to 0.088 mg/g) were found in patient's vomitus and the shrimp meat from both bait stores and commercial markets. A fragment of the cytochrome b gene (∼406 bp) was amplified by PCR using a pair of primers (UCYTB151F and UCYTB270R) from shrimp meat of two species and the vomitus. The vomited shrimp was identified as Parapenaeus fissuroides on the basis of gene sequencing and restriction fragment length polymorphism patterns after treatment with endonuclease Alu I. Based on the patient's symptoms and analytical data, we concluded that boric acid at toxic levels had been illegally added to the bait shrimp P. fissuroides.

COMMUNITY CHARACTERISTICS OF SHRIMPS IN THE OFFSHORE WATERS OF THE MID-SOUTHERN EAST CHINA SEA

Based on the data of the shrimp resources sampled by single trawler as investigation boat in 18 stations in the offshore waters of the Mid-Southern East China Sea (26°00'N—28°30'N,121°00'E—126°00'E) in May,August,November,2006 and February,2007,total catch from each trawler was counted and identified to species in taxonomy,and the spatial variation of the shrimp species composition,index of relative importance (IRI),the diversity and similar characteristics of the community structure were analyzed. 32 species of shrimp were caught in this survey,which belonged to 22 families under 11 genera. Comparison of the amounts of various species in different seasons:there are 22 species in the autumn which are the most; 20 species in winter,17 and 18 species in the spring and the summer respectively. According to the standard of index of relative importance (IRI) (the species with IRI above 1000 were regarded as the dominant species in this paper),there were 10 dominant species:Metapenaeopsis longirostris,Metapenaeopsis dalei,Solenocera alticarinata,Plesionika izumiae,Ibacus novemdentatu,Parapenaeus fissuroides,Solenocera koelbeli,Solenocera crassicornis,Parapenaeopsis hardwickii and Solenocera crassicornis,and 5 of them were major dominant species which were Metapenaeopsis longirostris,Metapenaeopsis dalei,Plesionika izumiae,Parapenaeus fissuroides and Parapenaeopsis hardwickii. Defined the ones with IRI values ranging from 100 to 1000 as common species,we got 7:Metapenaeopsis barbata,Penaeus japonicus,Plesionika dentirostris,Palaemon gravieri,Alpheus japonicus,Parapandalus spinipes and Sicyonia cristata. The abundance of the dominant species was varied with seasons. For example,5 were in May:Metapenaeopsis longirostris,Metapenaeopsis dalei,Parapenaeopsis hardwickii,Solenocera alticarinata and Plesionika izumiae,89.15% of the total catch and 92.14% of the total individuals. In August,there were 7 dominant species:Metapenaeopsis dalei,Plesionika izumiae,Metapenaeopsis longirostris,Parapenaeus fissuroide,Solenocera crassicornis,Ibacus novemdentatus and Solenocera alticarinata,91.82% of the total catch and 95.05% of the total individuals. In November,the number of dominant species increased to 8:Metapenaeopsis longirostris,Plesionika izumiae,Parapenaeus fissuroides,Metapenaeopsis dalei,Solenocera crassicornis,Ibacus novemdentatus,Solenocera koelbeli and Solenocera alticarinata,occupying 95.31% and 97.56% of the total catch individuals,respectively. In February,the number reduced to 5:Metapenaeopsis longirostris,Parapenaeus fissuroides,Metapenaeopsis dalei,Solenocera koelbeli and Plesionika izumiae,88.76% and 94.93% respectively. Based on their adaptability to habitats,all recorded species of shrimps were categorized into the hyperthermal and hysaline community in the Mid-Southern East China Sea. The stations with high abundance were mainly located in the west of the 120m isobaths,and gradually lower toward the autumn to winter,while it reached the lowest in winter. Margalef index (D) and Shannon-Wienner index (H') were higher in summer and autumn than those in winter and spring,Pielou's evenness index (J') in the offshore waters of the Mid-Southern East China Sea was stable through every season. The result indicated that the diversity index west of the 120m isobaths was higher than in the east. By hierarchical cluster analysis and non-metric multidimensional scaling (NMDS) assisted analyzing,the types of shrimp assemblage determined by influential factor such as aquatic system,water mass and salinity etc. in the East China Sea in spring were also discussed in the article,two main assemblages were identified in the offshore waters of the Mid-Southern East China Sea,which were deeper costal shrimp assemblage and out shelf sea shrimp assemblage.

Temporal and spatial distributions of dominant shrimp stocks and their relationship with the hydrological environment in the East China Sea

To provide a scientific and technological base for fishery administration, holding a moratorium on fishing, and combating habitat degradation, a shrimp stock survey was carried out in May, August, and November 1998 and in February 1999. The study was conducted in the area between 26°00' N and 33o00' N and to the west of 127°00' E in the East China Sea using a multi-sac trawl-net, with 115 stations being sampled. Up to 2001, we had found 121 species, which belong to 63 genera under 22 families, and 41 species are of high economic value and in great abundance. Nine shrimp species were of great economic importance, whose stock accounted for 76.8% of the demersal total. They were Parapenaeus fissuroides, Metapenaeopsis philippi, Palaemon gravieri, Metapenaeopsis barbata, Solenocera koelbeli, Solenocera crassicornis, Trachypenaeus curvirostris, Solenocera melantho and Parapenaeopsis hardwickii (listed in stock order). The nine species belong to the eurythermal and eurysaline community and high thermal and high saline community, had different migration patterns and stocks, and their distribution patterns could be generally classified into three types: (1) dominating in the north or the south; (2) dominating to the north of and in the coast to the south of 30°00' N; and (3) dominating to the east of 60 m isobath, which were related to six water masses in the ECS near two lines, i.e., the 60 m isobath and 30°00'N latitudinal lines. Densely habited shrimps were found in all four seasons due to temperature and salinity frontiers and upwelling. The general stock density index was relatively higher in spring, summer, and autumn, when it surpassed 10 kg/h, while in winter, it was only 6.8 kg/h which might be caused by overfishing. According to the spawning areas of the nine species and their distribution patterns, to attain sustainable development of the shrimp fishery in the ECS, it is imperative to protect fishing areas and to hold a moratorium on catching to the west of 60 m isobath from April through October, and between 60 m and 100 m isobaths and to the south of 30oN from June through August and to limit fishing in winter.

The rise and fall of electrical beam trawling for shrimp in the East China Sea: technology, fishery, and conservation implications

Abstract Yu, C., Chen, Z., Chen, L., and He, P. 2007. The rise and fall of electrical shrimp beam trawling in the East China Sea: technology, fishery, and conservation implications. – ICES Journal of Marine Science, 64: 1592–1597. Since the 1980s, shrimp beam trawling has flourished in inshore waters of the East China Sea (ECS) off Zhejiang Province. By 2000, there were more than 10 000 beam trawlers operating in the area. The fishery targets several species of shrimp, including Parapenaeopsis hardwickii, Solenocera crassicornis, Parapenaeus fissuroides, and Trachypenaeus curvirostris. In the early 1990s, electrical beam trawls using pulse generators, powered either from the vessel or from underwater battery packs, became popular in the fishery. As a result of this new technology, the catch rates of shrimp, especially the burrowing shrimp species, increased. At its peak usage, there were more than 3000 vessels using electrical beam trawls in Zhejiang Province and another 500 or more in the adjacent provinces of Jiangsu and Fujian. This technology was also widespread along the Chinese coast, but a lack of regulation resulted in the misuse of electrical pulse parameters that caused damage to juvenile shrimps and other benthic species. In 2001, this fishing method was banned from the waters off Zhejiang Province, and subsequently in other parts of the ECS. This paper reviews the research on electrical beam trawls, the fishery, and fishery-management issues associated with this new technology.

Phylogenetic Relationships of 12 Penaeoidea Shrimp Species Deduced from Mitochondrial DNA Sequences

DNA sequences of an 847 bp fragment of mitochondrial cytochrome oxidase subunit I (COI) gene and a 514 bp fragment of 16s rRNA gene were determined to examine the phylogenetic relationships of 12 Penaeoidea shrimp species (Penaeus chinensis, Penaeus japonicus, Penaeus penicillatus, Penaeus vannamei, Penaeus canaliculatus, Trachypenaeus curvirostris, Metapenaeus affinis, Metapenaeus ensis, Metapenaeopsis barbata, Parapenaeus fissuroides, Parapenaeopsis hardiwickii, Solenocera crassicomis). Both fragments of the swimming crab Portunus trituberculaus chosen as the outgroup were also sequenced. Intraspecific sequence divergence of 0.24-1.2% in the COI gene was found in 5 species, while no intraspecific variation was observed in the 16s rRNA gene. Three phylogenetic trees based on the 1361 bp combined sequences of COI and 16s rRNA were concordant in indicating the following suggestions: (1) phylogenetic relationship of the 11 Penaeidae species based on our result support the opinion of Burkenroad (Burkenroad, M.D. (1983). Crustacean Issues 3:279-290) on the basis of morphological features; (2) it seems more reasonable to class Solenocera crassicorni in the family Penaeidae; (3) the fragment of the COI gene chosen here appears to be a good marker for speciation studies and population analysis in Crustaceans, while the 16s rRNA gene fragment here seems suitable for examining phylogenetic relationships at the species or genus levels in Crustaceans. Our time estimates suggest that Penaeus and Metapenaeus might have separated about 6.38 x 10(6)-7.98 x 10(6) years BP in the post-Miocene, and the species separation within Metapenaeus and Penaeus might occur 0.08 x 10(6)-0.4 x 10(6) years BP in the late Pleistocene.
