“…In Ise Bay, population dynamics of two dominant megabenthos species, the dragonet Repomucenus valenciennei and mantis shrimp Oratosquilla oratoria , were affected by the oxygen‐poor water 20,21 . According to these studies, populations of the dragonet in the bay were established and maintained by individuals able to avoid the oxygen‐poor water and also by the new recruits derived from larvae released by spawning in autumn.…”

The present study dealt with seasonal and interannual variations in the abundance and biomass, and spatio-temporal distributions of the portunid crab Charybdis bimaculata dominant in Ise Bay, central Japan. The abundance and biomass of the crab decreased in summer when the oxygen-poor water developed in central or inner parts of the bay, and then increased through new recruits from autumn (October-November) to the following spring (March-May) when the oxygenpoor water disappeared. Berried females were collected mainly from spring to autumn. Recruits were collected in any season. Particularly in winter, most recruits were located in the innermost part of the bay. According to the cohort separation based on size frequency distribution in carapace width of the crab specimens, the cohorts that were derived from spawning in spring to summer largely contributed to establishing and maintaining the benthic populations for the following year in the bay, whereas those from other seasons failed to recruit because of serious damage caused by the oxygen-poor water. Most crab individuals one year post hatch contributed to spawning and then died by the winter of the same year.

In order to examine the seasonal and spatial patterns of stomatopods in the main bays of Guangdong Province, China, investigations were carried out seasonally using a semi-balloon otter trawl. A total of 11 species belonging to 10 genera of 2 families was collected. Oratosquilla oratoria and O. interrupta were the two most ubiquitous species, followed by Harpiosquilla raphidea and Miyakea nepa. IRI analyses (= indices of relative importance) revealed that these four were the most important species and accounted for 97.4% and 98.6% of the total abundance and biomass, respectively. The biological characteristics and seasonal variations in the catches implied that recruitment of O. oratoria and O. interrupta started in summer, whereas that of M. nepa and H. raphidea started in autumn. The aggregations and nMDS ordination analysis (= non-metric multidimensional scaling) based on catch rates revealed the existence of three groups. Hailing Bay and Shantou Bay formed Group 1, representing the most abundant fishery grounds. Honghai Bay, Daya Bay, Dapeng Bay, Shuidong Bay, and Liusha Bay formed Group 2, and were characterized by a moderate abundance of stomatopods. The last group (Group 3), with the lowest level of capture, comprised only Leizhou Bay, with no catch in winter. The spatial and temporal variations in the catch were mainly associated with characteristics of the sediment, life cycles, and a "mid-summer fishing moratorium" conservation measure, but not significantly with water depth, temperature, or salinity, according to BIO-ENV (biology-environmental) analysis.
