Summary: The neuroendocrine effects of municipal discharge and rainfall overflow on mussels were compared in this study. Municipal effluent led to feminizing effects and inflammation, while rainfall overflow specifically affected the Vtg protein levels and reproductive function in females.

Summary: Native freshwater mussels are endangered globally, emphasizing the importance of studying them for conservation efforts. This study examines the impact of physical disturbances and sedimentary habitat on the growth of Elliptio complanata mussels. It finds that sediments provide a refuge for juvenile and young adult mussels, while disturbance events do not negatively affect their growth.

Summary: Peanut skin proanthocyanidins have been proven to enhance growth performance and regulate lipid metabolism in juvenile American eels, with the best effects observed at a supplementation level of 900 mg/kg.

Summary: This study evaluated the supplementation effects of Macleaya cordata extract (MCE) on the growth performance, serum biochemical parameters, and intestinal health of the juvenile American eel. The results showed that adding 50 mg/kg or 100 mg/kg of MCE significantly improved growth performance, increased the activities of certain enzymes, and reduced the levels of certain substances in the blood, indicating improved health status. The 50 mg/kg MCE also had positive effects on the intestinal microbiota.

Summary: This study evaluated the supplementation effects of compound acidifiers (CAs) in the diet of American eel. The results showed that 4.0 g/kg of CAs promoted growth performance, decreased serum lipid levels, modified liver and immune function, and increased calcium and phosphorus utilization. However, 5.0 g/kg of CAs had negative effects on growth performance, serum biochemical parameters, and calcium and phosphorus utilization. The recommended level of CAs in the diet for optimal weight gain and feed conversion ratio in juvenile American eel was 3.5-3.7 g/kg.

Summary: Sagittal otoliths in hatchery-reared juvenile Atlantic salmon can be affected by vaterite, which may impair hearing and balance. However, structural tank enrichment did not directly affect vaterite formation. After release into the wild, salmon fry with vaterite otoliths were less likely to be eaten by predators and more likely to be recaptured in the river.

Summary: Recruitment of temperate eel species such as European eel, American eel, and Japanese eel has declined due to overfishing, migratory barriers, and hazardous energy infrastructure. An agent-based model was developed to simulate juvenile eel migration in estuaries, incorporating relevant eel behaviors and environmental conditions. The model results suggest that including bed anchoring behavior and salinity detection threshold are crucial for accurate simulation.

Summary: Filter-feeding mussels enhance organic matter flows between the water column and the bottom, and deposit-feeding sea cucumbers are potentially optimal candidates to bioremediate mussel organic waste. A comparative investigation on the suitability of different Mediterranean sea cucumber species was conducted for the first time. H. tubulosa showed high survivorship and positive growth, making it an optimal candidate for IMTA with M. galloprovincialis operating farms.

Summary: The study found that juvenile eels have different personality traits, with slower swimmers more likely to successfully use fishways for passage. Eels with successful climbing had shorter lengths, indicating that personality and size may influence fish segregation at barriers.

Summary: This study investigated the effects of replacing white fish meal with low-quality brown fish meal on the growth performance and intestinal health of American eels. It was found that with the addition of 0.50% compound additives, low-quality brown fish meal can replace 20% of white fish meal without detrimental effects on eel growth and intestinal health.

Summary: Standardizing data collection is crucial in ecological research to avoid bias. In this study, differences in eye diameter between the left and right eyes were within measurement precision, while no significant difference was found in pectoral fin length. Visual determination of maturation stage differed from calculated indices, but both methods could provide useful information. Computer software generated more precise measurements but increased interobserver variability, suggesting that the measuring method should be chosen based on the required level of precision.

Summary: Understanding the drivers behind size variation is important, as body size often predicts energetic requirements and fecundity. Neo-Bergmann's rule states that larger individuals are found at higher latitudes, and this size variation is attributable to temperature gradients.

Summary: Plant species in eastern Asia have larger climatic niche spaces compared to their counterparts in eastern North America. Congeners of eastern Asia-eastern North America disjunct genera tend to occupy similar or equivalent climatic niche spaces within their respective distributions, possibly due to their physiographic contexts.
