Summary: Glyphosate levels and transfer across trophic levels in zooplankton have been rarely studied. It was found that glyphosate was more likely to be incorporated through the medium than through food (zooplankton). The intake of glyphosate led to decreased survival and feeding rates in zebrafish larvae, while zooplankton species bioconcentrated glyphosate in large quantities.

Summary: In recent years, there has been increasing concern regarding the presence and accumulation of plastic debris in the environment, as well as the impact of microplastics (MPs) on biota. This study conducted a fish embryo toxicity test on zebrafish exposed to polystyrene MPs, revealing that the MPs had a moderate delay on hatching and caused deformities and compromised visual structure in larvae development. Additionally, increased gene transcription involved in oxidative stress and cellular detoxification were observed in the MPs-exposed zebrafish larvae.

Summary: Zebrafish, with their biological similarity to mammals and complex social behaviors, are an attractive model for studying normal and impaired social behavior. A study found that individual zebrafish show a preference for established shoals over newly-formed ones, with males spending more time investigating between the two shoals compared to females. This novel technique of using established versus newly-formed shoals can be used in future studies on autism spectrum disorders and other disorders affecting social interaction.

Summary: The widespread agricultural use of neonicotinoids poses a threat to non-target organisms. However, existing toxicity data for these pesticides does not consider the influence of environmental factors such as temperature. This study assessed the temperature-dependent toxicity of six neonicotinoids, finding that temperature had an inverted V-shaped relationship with toxicity. The results provide valuable information for evaluating the effects and mechanisms of neonicotinoids, particularly in the context of climate change.

Summary: In this study, the behavioral effects of imidacloprid on zebrafish were investigated at environmental concentrations. Integrated transcriptomic and metabolomic analysis revealed that disruption of circadian rhythm, metabolic imbalance, and neurotransmitter disorder were the underlying molecular mechanisms of behavioral impairment induced by imidacloprid. The identified genes and metabolites could serve as biomarkers to assess the ecological risk of imidacloprid to aquatic organisms and even human beings.

Summary: The effect of temperature on gonadal development and sex ratio in Brycon orbignyanus was assessed in this study. Fish were kept at three different temperatures (20°C, 23°C, and 26°C) from the beginning of exogenous feeding. Results showed that the sexual pattern was temperature-dependent, with undifferentiated individuals at 20°C and a higher proportion of immature males at 23°C and males in maturation process and regression phase at 26°C. Testosterone levels were quantified in all treatments, while detectable estradiol levels were found only at 23°C. Continuous exposure to 23°C and 26°C favored testicular development, with faster gonadal development observed at 26°C.

Summary: Household insecticides, especially pyrethroids, which are commonly used for insect control, have low toxicity for mammals at low doses. However, our study shows that sublethal doses of a prallethrin-based insecticide have adverse effects on the behavior and physiology of Caenorhabditis elegans, especially during transgenerational and lifespan exposure. These effects are indicated by changes in biomarkers such as decreased acetylcholinesterase activity, retardation of heat shock protein expression, and increased aggregation of PolyQ40, suggesting a potential link to neurodegenerative conditions like Huntington's Disease.

Summary: Pyrethroids prallethrin and transfluthrin are commonly used insecticides, but their safety in animals and humans is a concern. The impact of these insecticides on the antioxidant system of zebrafish was studied, and it was found that different tissues showed different responses. The muscle tissue was the most affected, potentially related to neurodegenerative conditions. In the brain, the compounds inactivated the first line of enzymatic antioxidant defense but the second line compensated, avoiding cellular damage. The gill tissue did not show lipid damage but had a significant effect on heme group formation.

Summary: The trade of aquarium organisms is expanding globally, but few initiatives have been taken to ensure sustainability. However, there has been a growing interest in researching captive breeding of these animals to promote a more sustainable aquarium hobby. In this study, we investigated how background color affects the endocrine stress response of tomato clownfish larvae, and found that white tanks should be avoided for larviculture. Using colored tanks can lead to less stress and better welfare conditions for captive-bred clownfish, which has practical applications for the ornamental aquarium trade.

Summary: The aim of this study was to examine whether a single acute exposure of a glyphosate-based herbicide (GBH) affected the growth performance of Nile tilapia fingerlings during the first 90 days of culture. The findings suggest that GBH increases serotoninergic activity, which affects fish anorexically. In addition, the fish were also exposed to fluoxetine (FLU), a drug that increases serotoninergic activity. The results showed that fingerlings exposed to GBH or FLU had decreased growth performance compared to unexposed fish.

Summary: Pyrethroid-based insecticides, such as prallethrin and transfluthrin, are commonly used for mosquito control. These compounds affect the nervous system of insects by keeping the sodium channels open, leading to hyperexcitability and eventually death. This study examined the effects of chronic exposure to these insecticides on zebrafish, focusing on their behavior and the activity of the enzyme acetylcholinesterase (AChE) in different brain regions. The results showed that both compounds caused anxiolytic behavior, reduced shoaling formation, and impaired social interaction in zebrafish. The AChE activity was also found to be modulated by these compounds, suggesting a possible link between pyrethroid insecticides and neurological disorders such as autism spectrum disorder and schizophrenia.

Summary: The use of zebrafish as a model organism in epilepsy research is increasing. However, there is a lack of standardized protocols, making it difficult to compare results between studies. This systematic review provides a comprehensive overview of chemically-induced seizure models in zebrafish. The most common chemoconvulsants used were pentylenetetrazole, kainic acid, and pilocarpine, with significant variability in administration route, exposure duration, and dose/concentration. Improved methodological and reporting practices are needed to enhance the reproducibility and reliability of zebrafish models for studying epilepsy.

Summary: In this study, the effects of N-acetylcysteine (NAC) and Acetyl-l-carnitine (ALC) on acute PTZ-induced seizures in adult and larval zebrafish were evaluated. The results showed that neither NAC nor ALC at any tested concentration were able to reduce PTZ-induced epileptic seizures. In contrast, administration of diazepam showed a significant reduction in seizure intensity and increased latencies to higher scores of epileptic seizures.

Summary: The effects of 30-minute exposure to environmentally relevant concentrations of imidacloprid-based insecticides (IBIs) on the behavior, redox status, and cortisol levels of zebrafish were investigated. The results showed that IBI decreased fish locomotion and social and aggressive behaviors and induced an anxiolytic-like behavior. Furthermore, IBI increased cortisol levels and protein carbonylation and decreased nitric oxide levels. These changes were mainly observed at concentrations of 0.013 and 0.0013 μg·L-1 of IBI. In an environmental context, these behavioral and physiological imbalances can impair the ability of fish to evade predators and affect their survival.
