Summary: Successful captive reproduction and hatchery-based seed production are crucial for sustainable aquaculture development of grey mullet in India. The study compared induced breeding and reproductive performance between grey mullet populations sourced from east and west coasts of India, revealing successful reproductive maturation in the eastern population and reproductive dysfunctions in the western population.

Summary: Skates and rays are susceptible to commercial fisheries due to their low fecundity, delayed maturation age, and slow growth rates. This study aimed to understand the age and growth characteristics of the long-nose skate in the Northeastern Mediterranean Sea. The results show that the Robertson (logistic) growth model adequately explains the relationship between age and total length. The study provides valuable data for comparison with previous studies and contributes to the correct management of the species.

Summary: This study examines the structure and elasticity of weevil rostra, finding that modifications to the composite structure of the rostral apex affect the bending capability and fracture risk, reducing the risk of structural failure.

Summary: The ultrastructural characteristics of the entry and bioaccumulation of Fe3O4 nanoparticles in the small intestine of Cyprinus carpio were studied. The extent of damages increased with the nanoparticle concentration, and only particles with a maximum size of 20 nm could penetrate the intestinal wall.

Summary: The concentrations of metal ions in the white and brown meats of the blue swimmer crab in Bahrain were determined. It was found that the crab accumulated higher levels of zinc and copper ions in the white meat, while elevated levels of cadmium were detected in the brown meat. The estimated weekly intake of these metal ions through consumption of the crab's white meat was below the maximum recommended values, indicating no potential health risk.

Summary: Growth parameters and mortality rates of Xyrich-tys novacula were determined using a sample of 115 individuals collected between June 2015 and October 2019 in the Gulf of Tunis. The sample ranged from 9.8 to 19.2 cm total length (TL), with females having a significantly smaller mean TL than males. Length-weight relationships for males and females showed positive allometric somatic growth. Age was evaluated using otoliths, and 6 age classes were determined. Von Bertalanffy growth parameters for the whole sample were calculated, along with total mortality, natural mortality, fishing mortality, and exploitation rate.

Summary: This research aimed to describe the structural and ultrastructural characteristics of the palate of red-rumped agoutis. The study found that while the structural characteristics are similar to other mammals, the morphology of the palate in agoutis differs in terms of the number and disposition of palatine ridges, as well as the shape of the conical CTCs.

Summary: This study provides a comprehensive anatomical comparison of the vascular pigmented pecten oculi of Anas querquedula and Gallinula chloropus chloropus. The differences in structure and organization of the pecten oculi, particularly in terms of the number and type of pleats, were significant between the two examined bird species.

Summary: This study was conducted off Saros Bay in the Northern Aegean Sea, Turkey between January 2020 and December 2020. A single specimen of Spondyliosoma cantharus was caught with a maximum length of 41.0 cm and total weight of 1050.00 g. The study measured the total length using a ruler on a measuring board and calculated the weight-length relationship for all samples.

Summary: This study examined the concentrations of heavy metals in the blue swimmer crab and its surrounding environment in the coastal areas of Kuwait. The results showed that the carapace of the crab had the highest accumulation of heavy metals, followed by the gills and digestive gland. The metal concentrations also varied in different sampling locations, with highest levels found in crabs collected from Shuwaikh Port. This study confirms the blue swimmer crab as a suitable bioindicator for evaluating heavy metal pollution in marine ecosystems.

Summary: This study conducted experiments to assess the selectivity of diamond mesh codends in capturing largehead hairtail in the Beibu Gulf. Different mesh sizes were used, and models were fitted to the catch data to determine the best fit curve. It was found that the present minimum mesh size did not match the landing size and suggestions for the optimal configuration and mesh size were made.

Summary: Coleoptera are considered an important tool in criminal investigations, with Thanatophilus rugosus being a significant necrophagous beetle. New thermal summation models for all developmental stages of Thanatophilus rugosus have been provided in this study, helping forensic entomologists estimate post-mortem intervals. The study involved rearing beetles at different temperatures and calculating thermal summation constants for each developmental stage.

Summary: This study investigates the presence of small environmental microplastics in the liver of Serranus scriba fish caught from coastal regions in Tunisia. The findings reveal differences in the abundance, size distribution, and presence of plastic additives across different sites. The study also highlights the impact of microplastics on the cytotoxicity, genotoxicity, and neurotoxicity of the fish liver.

Summary: Allometric analyses of sexually selected structures have revealed important patterns and adaptations in weapons, ornaments, and genitalia. In this study, we investigated the allometry of the baculum in three large mustelids, finding that baculum size is possibly adapted to the average size of the female reproductive tract. Additionally, bacular shape and size varied greatly among species, suggesting functional differences in intromission.
