Summary: Marine seaweeds, particularly brown algae, are rich sources of bioactive metabolites like phlorotannins, which have high antibiotic and cytotoxic capacities. In this study, the minimum inhibitory concentrations (MICs) of different phlorotannin extracts from brown algae were evaluated using model unicellular organisms. Phlorotannin extracts from Desmarestia aculeata, Fucus vesiculosus, and Ectocarpus siliculosus exhibited the lowest MIC values against most tested organisms, while microalgae showed lower susceptibility. These brown algae species, which can be found in polar and temperate seas, may serve as promising sources of phlorotannins due to their abundant growth and considerable biomass.

Summary: This study investigates the effect of antibiotic exposure on behavior and adaptability of various algae taxa. The results show that Chlorella vulgaris exhibits remarkable adaptability to antibiotic stress and its growth is positively influenced by the presence of bacteria. Antibiotic challenges lead to the recruitment of specific bacterial consortia in the phycosphere, which contribute to host growth promotion and adaptability enhancement. Additionally, the algal phycosphere shows higher enrichment capability of antibiotic resistance genes (ARGs) compared to the surrounding water, and specific ARG profiles are recruited under antibiotic stress.

Summary: This study evaluated the acute and chronic toxicological effects of six fluoroquinolones on Daphnia magna. The NOEC values varied for different fluoroquinolones in the chronic study. Concentrations of ciprofloxacin, norfloxacin, and ofloxacin found in water sources from some countries may cause toxicological damage to D. magna.

Summary: This study found that exposure to water soluble synthetic polymers can cause life history changes and altered levels of reactive oxygen species in the freshwater key species D. magna, although acute mortality was not observed. These sublethal effects may result in cascading effects that can impact the entire food web.

Summary: The misuse of antibiotics is causing bacteria to acquire antibiotic-resistant genes, and the presence of cladoceran species in freshwater ecosystems has a significant influence on antibiotic-resistant bacteria and tetracycline-resistant genes. Daphnia obtusa can dramatically decrease the abundance of ARB and tet(A).

Summary: Aquaculture is rapidly growing, particularly in Central and Eastern Europe, with freshwater fish farming being common. Antibiotics used in aquaculture can lead to antibiotic resistance and pollution. This study evaluated the impact of intensive fish farming on water quality and environment, focusing on pollution transfer and presence of antibiotic resistance genes.

Summary: Tests using algae and/or cyanobacteria, invertebrates (crustaceans) and fish are crucial for assessing the ecotoxicity of substances and classifying them as hazardous or not to the aquatic environment. However, testing two dimensional (2D) graphene nanoforms requires additional attention and adaptations due to their unique attributes. This review critically analyzes existing studies and approaches to testing, providing important insights for future assessments and regulatory requirements.

Summary: The study investigated the single and mixture toxic effects of MC-LR and Phe mixtures on aquatic organisms, with results showing that the mixture toxicity was concentration-dependent and exhibited synergistic effects at low concentrations. The protective effects of high concentrations of MC-LR may lead to antagonistic effects. Furthermore, exposure to low concentrations of the mixture had a greater toxic effect on D. magna than either chemical alone.

Summary: This study explored the neurotoxicity of azithromycin in zebrafish and found that it may induce neurotoxicity by influencing the VEGF/Notch signaling pathway. Additionally, the study revealed the impact of azithromycin on the connection between blood vessels and the nervous system, providing new insights into the potential risks of antibiotics to aquatic organisms and human health.

Summary: A study found that freshwater fish primarily obtain fatty acids from aquatic sources, particularly from aquatic macroinvertebrates. Floodplains, with their higher algae production compared to river channels, are likely to be the major source of high quality food for fish and other aquatic animals. Differences in the composition of macroinvertebrate communities in fish habitats may affect food quality.

Summary: This study investigated the impact of ethylenediaminetetraacetic acid (EDTA) on the toxicity of boron to the algae species Chlamydomonas reinhardtii, Chlorella sorokiniana, and Chlorella vulgaris. C. vulgaris was the least sensitive to boron in the presence of EDTA, while C. reinhardtii and C. sorokiniana exhibited high sensitivity. The chelation of EDTA with micronutrients reduced their availability for uptake by the algae, leading to increased sensitivity to boron. These findings have implications for assessing and managing boron risk in aquatic ecosystems.

Summary: This study aimed to identify the optimal time and fishing methods for removing exotic fishes from Longluan Lake. Results showed that using lure fishing, longline fishing, and fyke netting during April to June achieved the best results. The study also recommended specific fishing methods for different exotic fish species. Combining lure fishing and fyke netting in both natural and artificial habitats was found to be the most effective approach for controlling exotic fishes in the lake.

Summary: The study aims to record fish composition and assess conservation potentials for native fishes in urban ponds of southern Taiwan. The results show a total of 20 fish species, with 15 exotic and 5 native species, were found in the ponds, including some common and near-threatened species. The study suggests that the first five years after establishing urban ponds are critical for the sustained survival of native fishes.
