Summary: In freshwater ecosystems, flood pulses, connectivity between environments, and vegetation mosaic are the main variables affecting environmental structure. Local limnological conditions are more important for structuring river fish assemblages. However, these limnological characteristics can have combined impacts on the environment. This study evaluates the main drivers of fish trophic guilds in lakes and determines the importance of limnological conditions, spatial distance, and riparian vegetation. Limnological variables and riparian vegetation influenced the distribution of trophic guilds, especially during low water periods.

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: The diversification of tapeworms of the subfamily Gangesiinae, parasites of catfishes, is evaluated using molecular and morphological evidence. The Indomalayan region appears to be the ancestral homeland and a major center of diversification of these tapeworms, with range expansions in western and northern parts of Eurasia and Africa.

Summary: Geodiversity refers to the variety of abiotic elements and processes present at different scales and dimensions in an area. This study quantified and assessed geodiversity in the Marrecas River drainage basin in southern Brazil, finding lower geodiversity in certain interfluves and estuary areas, and higher geodiversity in valleys. The results highlight the importance of not solely focusing on the richness of geodiversity, but also considering the spatial distribution of environmental components in the study area.

Summary: The Parana River is considered one of the top-ten major rivers in the world, with its upper basin significantly modified by agriculture expansion and dam construction during the past century. However, the middle and lower sections remain as some of the few free-flowing river reaches of this magnitude globally. The study examined hydrological characteristics from 1905 to 2019, analyzing changes in flow regime and connectivity processes in the Middle Parana River floodplain, and discussed potential implications on ecosystem functioning due to regional disturbances in the large river basin.

Summary: This study is the first fish inventory of the Agua das Araras stream, a small tributary of the Laranjinha River in the upper Parana River basin. A total of 5,328 specimens were collected, representing 41 species from six orders and 15 families. The most representative orders in terms of species richness were Siluriformes and Characiformes. Among the families, Characidae and Loricariidae showed higher richness, contributing to about 36.6% of all collected species. The most frequent species captured in the majority of sampled sites were Astyanax lacustris, Characidium aff. zebra, Corydoras aeneus, and Imparfinis schubarti. The results highlight the importance of sampling small aquatic bodies for maintaining fish diversity in Neotropical freshwater environments.

Summary: River connectivity is crucial for the resilience of fish assemblages and populations, and is a top priority for achieving good ecological status in river systems. The assessment of different types of multispecies fishways in a Mediterranean-type river showed clear ecological contributions, including their use as migration corridors and compensatory habitats for small and juvenile fish.

Summary: The study focused on microplastics pollution in Dafeng River in Guangxi Province, China. The research found that while the river had relatively low microplastics pollution levels, aquatic organisms, particularly fish, showed more severe contamination. This highlights the need for attention to microplastics pollution in organisms of remote rivers.

Summary: This study evaluated the impact of initial stocking density and water recirculation rate on larval yield and production of competent larvae in a recirculation aquaculture system. The results showed that the production of Crassostrea gigas larvae was feasible at recommended densities, with the water renewal rate affecting both yield and competent larvae. Oyster cultures with specific stocking densities and water flow rates showed the best results in terms of yield and rate of competent larvae.

Summary: This study aimed to analyze the effect of salinity on the bioaccumulation and depuration of Escherichia coli in Anomalocardia brasiliana. The results showed that A. brasiliana had higher bioaccumulation of E. coli at higher salinities, while 48-hour depuration at salinity 25 resulted in the greatest reduction of E. coli. Salinity 20 showed low bioaccumulation and depuration efficacy for E. coli.

Summary: Oysters are commonly used as sentinel organisms to monitor the effects of contaminants. This study evaluated the molecular and histological responses in male and female oysters exposed to PYR. CYP2AU1 levels were found to be a good biomarker for PYR exposure, and the interpretation of biomarker responses should consider gender.

Summary: Fish parasites, such as Neoechinorhynchus buttnerae, can accumulate high concentrations of trace metals and serve as bioindicators of environmental contamination. The presence of metals in the parasite was significantly higher than in the host fish Colossoma macropomum, indicating their ability to accumulate metals. The results suggest that the parasite directly influences the concentrations of trace metals in the fish tissues.

Summary: Understanding the effects of salinity on the reproductive cycle of tropical oyster, Crassostrea tulipa, is important for hatchery conditioning management. Two experiments were conducted to evaluate the effects of salinity on the broodstock's reproductive cycle, showing that salinity affects the maturation and reproductive stages. The results are considered a first step towards developing a protocol for C. tulipa conditioning in hatchery conditions.

Summary: This study investigated the genetic structure and diversity of the mangrove oyster in wild and cultivated populations in Brazil. Two main genetic groups were identified, one from cultivated populations and the other from wild populations along the southern and southeastern Brazilian coasts. Despite variability, the cultivated population showed relatively high genetic diversity values. Monitoring and establishing reference values for genetic diversity can aid in the viability of cultivated populations and the management of wild populations.

Summary: This study evaluated the pharmacokinetic profile of basil essential oil in juvenile tambaqui. The results showed that the oil was rapidly absorbed and distributed to different tissues in the fish, with varying half-lives in plasma and various tissues. Histological evaluation of the fish gills showed reversible lesions, while no changes were observed in the liver and spleen. The biochemical and pharmacokinetic results confirmed the safety and rapid elimination of basil essential oil in tambaqui.

Summary: This study aimed to conduct an integrative taxonomic approach to identify native Crassostrea mangrove oyster species in Brazil. The results confirmed the presence of two species, C. rhizophorae and C. gasar, and revealed that C. brasiliana and C. mangle are synonyms of C. gasar and C. rhizophorae respectively. The study also identified a new species, C. tulipa, which is disconnected from any previously described mangrove oyster species in Atlantic seas.

Summary: This study compares the growth and survival of Crassostrea gigas spat at four sites in Brazil. The SBQ site has higher particulate matter values, while the PAR site has higher salinity and lower temperature. There were no differences in survival among the sites in 2018, but significant differences were observed in 2019. The SBQ and ATL sites are found to be more suitable for spat cultivation than the PAR and CDO sites.
