Abstract Capitulum mitella is an important species in the intertidal ecosystem and in the economy in China. This study explored the genetic diversity and population structure of C. mitella using mitochondrial 16S ribosomal subunit (16S rRNA) gene sequences. The researchers sequenced a 527 bp fragment of 16S rRNA from 390 samples collected from six localities along Western Taiwan Strait and identified 45 distinct haplotypes with an average haplotype diversity ( h ) of 0.451 and an average nucleotide diversity ( π ) of 0.00124. The pairwise statistics and AMOVA indicated a lack of significant population structure. The results indicated a recent expansion of the population of C. mitella in the study area. This expansion, combined with the species’ high dispersal capabilities, limited physical barriers, and the influence of oceanic currents, may be the factors contributing to its current phylogeographic structure. This study provides particularly important information for managing and protecting the resources of C. mitella in Southern China.

Abstract Many species of hermit crabs, such as Calcinus and Clibanarius spp., live on the rocky shores of tropical and warm temperate regions. During low tides, some of these species climb out of the tidal pools onto rock surfaces exposed to the air. In the genus Calcinus , however, such ‘Air-exposure (AE) behaviour’ was only known previously from Calcinus laevimanus . During a field study of the hermit crab fauna on Amami Oshima Island, Kagoshima, Japan, the AE behaviour of Calcinus elegans (Decapoda, Diogenidae) was observed on rocky shores. Moreover, the repeatability of the AE behaviour was confirmed. Therefore, we documented the AE behaviour of C. elegans as a second record of AE behaviour among Calcinus species by providing videographic evidence. The findings indicate that the AE behaviour has evolved in a broader range of Calcinus species than was previously assumed.

Abstract Irodes callionymi (Yamaguti, 1939) is redescribed based on specimens of both sexes recovered from the bucco-branchial cavity and the body surface of Synchiropus altivelis (Temminck & Schlegel, 1845) (Callionymidae) in Japan. The male, as well as copepodids V and IV are described for the first time for the species.

A new species of the wholly freshwater hymenosomatid crab genus Limnopilos Chuang & Ng, 1991, is described from Tonle Sap River in the lower Mekong drainage, Cambodia. This is the fourth species known, and the second one from Indochina. The type species, of Limnopilos, L. naiyanetri Chuang & Ng, 1991, was from the Chao Phraya drainage to the west in central Thailand. The new species is characterized by the presence of a rostrum, relatively shorter ambulatory legs and a different structure of the male first gonopod. Limnopilos sumatranus Naruse & Ng, 2007, is also recorded from southern Peninsular Malaysia for the first time.

The green tiger shrimp, Penaeus semisulcatus, is a commercial species supporting important fishery along the Palk Bay coasts. It is a much sought-after seafood commodity influencing the livelihood of the local fishers. This study aims to investigate the fecundity of the species in relation to its morphometry. Fecundity is an index of reproductive capacity used to calculate a stock’s reproductive potential and the egg’s survival. The absolute fecundity of the shrimp ranged from 26 100 to 750 000 ova alive per female, and the mean absolute fecundity from 59 100 to 583 000 ova alive per female. The relationship between fecundity and the morphometric measurements showed a positive exponential correlation. One-way ANOVA indicated a significant difference in the different size classes’ carapace length, total weight, ovary weight, absolute fecundity, stomach weight, and gastrosomatic index. There was no significant difference between the relative fecundity and the gonadosomatic index. This study provides insight into the reproductive potential of P. semisulcatus for efficient management of the resource in Palk Bay, Tamil Nadu, India.

This present paper presents an inventory of benthic Malacostraca in the Gulf of Oran. The softbottom crustacean fauna was studied between February 2021 and September 2021. Samples were collected from 8 coastal stations. The class Malacostraca was represented with 2 subclasses, Eumalacostraca and Phyllocarida. Sixty-one species and 290 individuals belonging to seven crustacean orders (Amphipoda, Decapoda, Isopoda, Tanaidacea, Mysida, Lophogastrida and Leptostraca) were identified. Amphipoda were represented with the highest number of species (36) followed by Decapoda (11) and Isopoda (6). Tanaidacea and Mysida were poorly represented, with 3 and 2 species, respectively. Lophogastrida and Leptostraca were both represented by only one species. Among the crustaceans encountered, Ampelisca was the most dominant genus. The present inventory indicates that the carcinological fauna in the Gulf of Oran is less diversified than it is in other zones that have been studied on the Algerian coast (Gulf of Arzew, Bay of Bou-Ismail, and Bay of Algiers).

Body size is a crucial metric that is often obtained during the breeding migration of female land crabs. Most commonly, these measurements are obtained by hand but hand-measuring them carries risks for both crabs and researchers. In this study, we developed a novel “photo-image approach” to measure the maximum carapace width of Cardisoma carnifex (Herbst, 1796) in the field, and compared the results with hand measurements. We found a significant relationship in the maximum carapace width measured between the two approaches (Linear regression, , ). The difference (0.54 ± 0.18 mm) and relative error (0.61 ± 0.19%) in the maximum carapace width measured between the two approaches were minimal. We suggest that the photo-image approach is feasible for determining crab size in the field. The approach holds promise for its application in citizen science projects, facilitating advancements in crab research.
