The species diversity of freshwater crabs of Bangladesh is poorly known. In this study, (Alcock, 1909) and (Alcock, 1909) are reported as new records from Bangladesh. The two species were identified through morphology and molecular phylogeny based on 16S rDNA gene sequences. Herein, diagnostic characters of both species are provided respective to close congeners. There is concern over the conservation status of due to its narrow distributional range. In addition, an updated checklist and a key to the freshwater crabs of Bangladesh are provided.

Objective: To investigate the prevalence of parasitic infections in market-sold aquatic products in Shanghai Municipality, and to understand the knowledge and practice towards food-borne parasitic diseases among residents, so as to provide insights into the surveillance and control of food-borne parasitic diseases.
Methods: Freshwater products, seawater products and pickled products were randomly obtained from agricultural trade markets, supermarkets, retail stores and restaurants in Huangpu, Putuo, Minhang and Qingpu districts of Shanghai Municipality from 2020 to 2023. Parasite metacercariae and larvae were detected in these aquatic products using pressing method, digestion method and the dissection method, and the detection of parasitic infection was compared in different types of aquatic products.

We describe an agent-based model purposed for social learning, which was developed by stakeholders, with the technical assistance of professional modelers, to facilitate stakeholder involvement in modeling issues related to the development of an adaptive environmental management plan for the Texas Gulf Coast (USA) estuaries. Stakeholders developed the model during six workshops that spanned a three-year period, and used the model to simulate the population dynamics (recruitment, growth, movement, and mortality) of blue crabs () in the Aransas and Copano Bays in response to various freshwater inflow and harvest scenarios. Results of scenarios representing normal, low, and high harvest levels indicated little effect on blue crab abundances, but harvests increased ≈75 % when harvest level was doubled and decreased ≈50 % harvest level was halved.

Paragonimiasis, caused by infection with lung flukes of the genus Paragonimus, remains a significant public health concern in Southeast Asia. In Lao People's Democratic Republic (Lao PDR), information on the distribution and genetic diversity of Paragonimus species is limited. This study investigated Paragonimus metacercariae in freshwater (mountain) crabs and analyzed their genetic diversity and phylogenetic relationships.

Saline-alkaline aquaculture plays a crucial role in the ecological restoration of saline soils, yet high water salinity can significantly restrict the growth of cultured organisms. The Chinese mitten crab (Eriocheir sinensis) is typically farmed in freshwater, to evaluate the effects of salinity stress on these crabs, this study conducted laboratory aquaculture experiments at salinities of ≤ 0.5 (freshwater), 6, 12, and 18 ‰.

The use of glyphosate (Gly) has caused unnecessary economic losses to the aquaculture industry, but research on the effect of Gly on is very limited. The aim of this study is to reduce the negative effects of Gly, reduce yield loss, and improve economic benefits through nutritional feed control technology. The experiment involved 80 crabs randomly divided into four groups: control group, Gly group (48.
