Summary: The consumption of contaminated finfish from the polluted river of Turag-Tongi-Balu, Kamarpara site, Dhaka poses significant health hazards to humans, with the concentrations of Cd, Mn, Pb, and Se exceeding the Food Safety Guideline value in most fish species. The high Mn concentrations in certain fish species elevate the non-carcinogenic risk, and there are statistically significant differences in heavy metal concentrations among fish species. The regular dietary consumption of fish from this polluted ecosystem poses a significant health risk and is indicated as cancer, emphasizing the importance of monitoring heavy metal contamination and minimizing the risk to human health.

Summary: The study evaluated metal accumulation in the cestodes Proteocephalus macrophallus parasitizing the tucunare, Cichla kelberi, in the Jacare-Guacu River, with lead, cadmium, aluminum, and nickel being well-accumulated elements. The concentration of trace metals in parasites was significantly higher than in the tissues of fish hosts, indicating the cestodes' capacity for metal accumulation. Non-infected fish had higher cadmium and lead concentrations compared to infected fish, and the size of the cestodes' populations influenced metal concentrations in host tissues.

Summary: This study evaluated the bioaccumulation and health risk of trace metal contamination in the musculature of Hoplias malabaricus fish collected from two rivers in southeastern Brazil. The results showed that the concentrations of trace metals in fish and water from the Jacare'-Guacu River were higher than those from the Jacare'-Pepira River, indicating a higher anthropogenic impact on the Jacare'-Guacu River. Additionally, elements such as aluminum, chromium, and cadmium, due to their high concentrations, may pose risks to the health of fish and the survival of their populations, as well as to humans who consume these animals as a food source.

Summary: The study revealed a close relationship between Hg concentrations in the water column of a Mediterranean lagoon and Hg contamination in commercial fish species, with smaller fish being more susceptible to Hg contamination and the East basin showing heavier pollution. Wind transport of plant masses may also contribute to increased levels of Hg in sediment.

Summary: The study utilized Prussian carp as bioindicator organism to estimate the impact of pollution through analysis of metal levels and biomarkers in the intestine tissue. It was found that contaminated sites had higher metal levels compared to reference sites, indicating environmental disturbance. The intestine was shown to be a suitable bioindicator tissue, clearly reflecting dietary metal uptake.

Summary: This study compared the effects of estrone and bisphenol-A alone and in combination on spermatogenesis in Astyanax bimaculatus. The results showed that estrone and the estrone + bisphenol-A mixture significantly altered the number of spermatogenic cells, while bisphenol-A exhibited higher cytotoxicity. Analysis suggested that the estrone + bisphenol-A mixture did not have additive or synergistic effects.

Summary: This study analyzed the intestinal morphology of Geophagus brasiliensis, a common fish in South America, using histological and histochemical techniques. The small intestine was characterized by intestinal villi covered by simple prismatic epithelium, while the large intestine lacked villi but had abundant goblet cells. Positive reactions to PAS and AB pH 2.5 were observed in goblet cells, indicating the presence of mucosubstances. This research provides valuable insights for phylogenetic studies on teleosts.

Summary: The study analyzed the quality of oocytes of Pampus argenteus using crude extract of common carp pituitary for induced reproduction. Results showed a 70% success rate for females and 100% for males in the reproductive process. Some females had low fertilization rates due to follicular atresia possibly caused by delayed hormonal administration or extrusion.

The results showed that manjuba had better reproductive success in lentic environments, especially in the Tres Marias reservoir section, where high temperatures, long photoperiod, and abundant rainfall coincided with the collection of individuals in the maturation/mature gonadal stage.

Summary: Congeneric sympatric species often reduce competition and interference by using behavioral and morphological adaptations. However, the reproductive patterns behind coexistence are still unknown. This study analyzed the gonadal morphology, reproductive cycle, and population structure of two congeneric fishes in a Neotropical river. The results showed similarities in gonadal development but differences in spawning habitats, reproductive periods, and body size. Despite broad overlap of reproductive traits, there was spatial and temporal differentiation in the reproductive biology between the two species.

Summary: In this study, researchers investigated the gametogenesis and reproduction of Bokermannohyla nanuzae in the Atlantic Forest in southeastern Brazil. They found that frogs of both sexes had mature germ cells almost year-round, indicating continuous gametogenesis. Advanced gonad maturation, where females spawn and males have sperm, primarily occurred during wet months. Male frogs were observed calling with mature testes throughout the year, but only had sperm from October to January.

Summary: This study analyzed the gametogenesis and reproduction characteristics of S. elegans from the Sao Francisco River in Tres Marias, Minas Gerais. The results showed that the first gonadal maturation occurred at a total length of approximately 10.5 cm in males and 15.0 cm in females. Reproduction mainly took place from September to April, during which there were high water temperature values. Females had a higher frequency at the mature and spawned stages, as well as a higher gonadosomatic index (GSI). In contrast, the reproductive peak for males was from November to February. The long spawning period and histological features of the spawned ovaries suggest that the spawning of S. elegans is of the partial type.

Summary: This study analyzed the genetic structure and population dynamics of Prochilodus lineatus in a remnant lotic system in southeastern Brazil. Significant genetic structure and three genetic clusters were identified in this river system, with asymmetric gene flow indicating source-sink metapopulation dynamics. The presence of a genetic cluster downstream from the Porto Colombia dam suggests a trapped gene pool in this highly dammed river basin.
