Summary: This study investigated the presence of microplastics (MPs) in the Macrobrachium amazonicum shrimp, an important food source consumed in the Brazilian Amazon. A total of 600 shrimp specimens were collected from urban and rural areas, revealing 2597 MP particles, with significant differences between the sampling sites. There were also significant differences in the distribution of MPs among different body parts. The most abundant MPs were dark blue fiber-type particles. Raman spectroscopy identified these fibers as polypropylene, while FTIR analysis identified light blue fragments as nylon. The presence of MPs in the M. amazonicum shrimp highlights their potential impact on the local population's diet and raises concerns about environmental contamination.

Summary: An ink-free printing method using agar and polyvinyl alcohol (AP) incorporated with curcumin was developed for monitoring shrimp freshness. The addition of curcumin improved the mechanical properties of hydrogel films while reducing water content. The intelligent indicator showed high colorimetric stability at low temperatures and could detect changes in shrimp freshness, providing both packaging information and reference function for indicators.

Summary: This study revealed that salinity significantly affected ion homeostasis, glucose metabolism and gill tissue structure in Macrobrachium nipponense. Salinity stress activated ion transport channels and promoted up-regulation of glucose metabolism. High salinity levels caused damage to the gill tissue of M. nipponense.

Summary: Studies on reproductive system morphology are crucial for understanding the reproduction processes of species, genera, or families. This study aimed to describe the functional morphology of the male reproductive system, spermatophore formation, and sperm count of Macrobrachium brasiliense. The anatomy of the reproductive system includes a pair of testes connected to the vasa deferentia (VD) extending to the fifth pair of pereopods. The VD is divided into proximal (PVD), middle (MVD), and distal (DVD) regions, each with distinctive epithelial characteristics. The typhlosole and columnar epithelium in the PVD play a role in asymmetrical spermatophore formation, which is a common pattern among caridean shrimps.

Summary: This study found that diets with a medium-to-high lipid content were important inducers of esterase activity, while shrimps exposed to CPO under a lipid-poor diet showed a significant enzymatic inhibition. The diet-dependent esterase induction suggests that the intake of fatty dietary items mitigates the esterase enzyme inhibition caused by CPO exposure.

Summary: A recent study on Penaeus Fabricius, 1798 suggests that all economically important shrimps should belong to a single genus, but there are some clades in the molecular phylogenetic tree that lack formal names. This study proposes subgeneric names for five of these clades in case Penaeus is split. A key to the subgenera in Penaeus is provided.

Summary: During the evolution of shrimp, key aspects of their organization have remained unchanged, leading to a large number of parallelisms within this group of arthropods. Ancient shrimp fauna may have originated in shallow waters, later expanding to the continental slope and pelagic zone due to adaptive radiation. This movement was associated with limited food resources on the slope, leading to a shift in diet among species.

Summary: The study compared sediment quality in estuaries at three locations along the coast of Sao Paulo State, Brazil, during two seasons of 2013. Results showed that sediments from the most protected locality had lower metal pollution and toxicity compared to those from less protected areas, which exhibited signs of environmental degradation.

Summary: The study revealed that the freshwater crab Pagei survives in fresh water by maintaining cellular isosmoticity, while the shrimp Jelskii exhibits clear hypo-osmoregulatory ability. Each of the two species has evolved distinct transcriptional and systemic strategies to adapt to the freshwater environment.

Summary: Salt tolerance in Brachyura is closely related to their ability to adjust body fluid concentrations, with mechanisms relying on the gill (Na+, K+)-ATPase. Callinectes danae demonstrates intricate osmotic and chloride regulation abilities under different salinity conditions, which are linked to variations in ATPase activity, protein expression, and mRNA expression.

Summary: This study focused on the ion regulation capabilities of palaemonid shrimps in different salinity environments. Palaemonids exhibit hypo-regulation in high salinity and hyper-regulation in low salinity. The research revealed a positive correlation between the expression of gill NKCC protein and the hemolymph's hyper-osmoregulatory capacity, suggesting a role for NKCC in salt secretion.

Summary: Early marine invertebrates adapted to dilute media by acquiring osmoregulatory abilities. These adaptations include reduced body permeability, lowered osmotic concentrations, and increased osmotic gradients. Assessing freshwater invertebrates that have successfully invaded this environment, we find diverse osmoregulatory characteristics influenced by body plans, morpho-physiological resources, and occupation routes.

Summary: Weakly osmoregulating crustaceans use intracellular free amino acids (FAA) to attenuate cell volume changes, but it is unknown if semiterrestrial, strong hyper/hypo-osmoregulators have this ability. This study investigates FAA mobilization in muscle tissue of 10 fiddler crabs from different genera along the Atlantic coast of South America. The results show that hypo-osmoregulating crabs can mobilize FAA, likely due to a lesser ability to secrete salt near their upper critical limits. On the other hand, hyper-osmoregulating crabs have a strong extracellular regulatory ability, so FAA plays a diminished role in isosmotic intracellular regulation.
