Behavioural responses in effect to chemical stress in fish
The maternal transfer and developmental toxicity of chiral contaminants with respect to enantioselectivity have rarely been investigated. Here, the residues and toxicological responses of cis-BF, a typical chiral pesticide, were studied in the progeny of adult zebrafish exposed to cis-BF (0, 20, 100, and 500 ng/L) for 60 days. Cis-BF enantiomers exhibited the equal maternal transfer potentials. GC/MSD analysis showed that parental 1S-cis-BF exposure could disrupt the components of fatty acids in offspring embryos. In transcriptional expression, the whole differentially expressed genes were significantly enriched in GO categories, including the processes related to lipid biosynthesis/metabolism. The perturbations of fatty acids suggested that cis-BF has potential negative impacts on embryos’ development. Furthermore, enantioselective growth inhibition and developmental neurotoxicity in larvae were also observed. The mRNA expressions of neuronal development genes were significantly changed in 1S-exposed offspring, so were the levels of the neurotransmitters and larval locomotion. Our results show that the cis-BF induced the growth inhibition and neurotoxicity in zebrafish larvae, which may be mediated by the development interference in embryos related to the disrupted fatty acid composition. Furthermore, the toxicological response to 1S-cis-BF was greater than that to the 1R-enantiomer in the offspring of exposed adults.
Pharmaceutical residues are polluting the surface water environments worldwide. Sewage and wastewater treatment, therefore, needs to be improved in order to remove pharmaceutical residues from the effluent. One such treatment improvement is effluent ozonation. Even though ozonation has proven to be very efficient in reducing pharmaceutical parent compound concentrations in wastewater effluents, much remains unclear regarding potentially toxic ozonation by-product (OBP) formation. In this study, we sought to elucidate the aquatic toxicity of ozonated pharmaceuticals in zebrafish (Danio rerio) embryos in a static 144 h post fertilization (hpf) fish embryotoxicity (ZFET) assay. Three pharmaceuticals commonly detected in wastewater effluents, i.e. carbamazepine, diclofenac, and oxazepam, were selected for testing. Toxicity was assessed before and after 1 min ozonation (0.053 mg L-1 peak O3 concentration) and 10 min ozonation (0.147 mg L-1 peak O3 concentration). Chemical analysis showed that carbamazepine and diclofenac were largely removed by ozone (90±11% and 97±3.8%), whereas oxazepam was removed to a lesser extent (19±5.7%). The ZFET assay revealed diverging toxicities. Diclofenac embryotoxicity decreased with increasing ozonation. Oxazepam did not cause embryotoxicity in the ZFET assay either pre- or post ozonation, but larvae swimming activity was affected at 144 hpf. Carbamazepine embryotoxicity, on the other hand, increased with increasing ozonation. Chemical analysis showed the formation of two OBPs (carbamazepine-10,11- epoxide and 10,11-dihydrocarbamazepine), possibly explaining the increased embryotoxicity. The results of this study highlight the importance of new chemical and toxicological knowledge regarding the formation of OBPs in post-ozonated effluents.

A set of adverse outcome pathways (AOPs) linking inhibition of thyroperoxidase and deiodinase to impaired swim bladder inflation in fish has recently been developed. These AOPs help to establish links between these thyroid hormone (TH) disrupting molecular events and adverse outcomes relevant to aquatic ecological risk assessment.
Although aggression is a common symptom of psychiatric disorders the drugs available to treat it are non-specific and can have unwanted side effects. In this study we have used a behavioural platform in a phenotypic screen to identify drugs that can reduce zebrafish aggression without affecting locomotion.
Highlights • Parental exposure to PFBS disturbed maternal transcript transfer in zebrafish. Toxic actions on maternal transfer of mRNA depended on exposure concentrations. Parental exposure to 10 μg/L PFBS impacted histone-DNA packaging in nucleosome. Parental exposure to 100 μg/L PFBS mainly affected adherens junction transcripts. Development, growth and neurobehaviors of offspring embryos were impaired.
Cadmium exposure induced changes of locomotor activity in zebrafish. The relative abundances of microbial phyla and genera were changed by cadmium. The expression of bdnf and genes involved in serotonin signaling were changed.

Detection of sound and head movement requires mechanoelectrical transduction (MET) channels at tips of hair-cell stereocilia. In vertebrates, the transmembrane channel-like (TMC) proteins TMC1 and TMC2 fulfill critical roles in MET and substantial evidence implicates these TMCs as subunits of the MET channel. To identify developmental and functional roles of this Tmc subfamily in the zebrafish inner ear, we tested the effects of truncating mutations in tmc1, tmc2a, and tmc2b on in vivo mechanosensation at the onset of hearing and balance, before gender differentiation.

Triphenyl phosphate (TPhP) has been shown to cause developmental neurotoxicty. Considering the visual system is a sensitive target, in the present study, we investigated the potential toxicity of TPhP on the visual development and function ACCEPTED MANUSCRIPT 2 in zebrafish larvae. Embryos were exposed to 0, 0.1, 1, 10, and 30 μg/L TPhP from 2 to 144 hours post-fertilization (hpf). The transcription of photoreceptor opsin genes, and histopathological changes in the retina and visual behavior (optokinetic and phototactic responses) were evaluated. TPhP significantly downregulated the transcription of opsin genes (zfrho, opn1sw1, opn1sw2, opn1mw1, opn1mw2, opn1mw3, opn1mw4, opn1lw1 and opn1lw2) in all exposure groups. Histopathological analysis revealed that the areas of the outer nuclear layer (ONL), inner nuclear layer (INL), and inner plexiform layer (IPL) of the retina were significantly reduced in the 10 and 30 μg/L TPhP groups. The number of ganglion cells was reduced significantly in the 30 μg/L group. The optokinetic response (OKR) and phototactic response showed dose-dependent decreases caused by impaired visual function, which was confirmed by unchanged locomotor activity. The results indicated that exposure to environmentally relevant concentrations of TPhP could inhibit the transcription of genes related to visual function and impair retinal development, thus leading to visual impairment in zebrafish larvae.

The link between tobacco use and the development of serious diseases such as certain cancers, heart disease, respiratory diseases and stroke are well established . Despite this, tobacco use continues to be a growing global epidemic and remains the leading cause of preventable death worldwide . More than 37,000 Canadians have been estimated to die prematurely on an annual basis as a consequence of tobacco smoking  and costs to the health care system are estimated at over $4.3 billion annually . As such, tobacco use remains a public health concern in Canada.
8–48 hpf is the sensitive exposure window for neurodevelopmental and behavioral toxicities of TBBPA. TBBPA induced apoptotic cell death and affected motor neuron and muscle fiber development. Zebrafish embryos rapidly absorbed and accumulated TBBPA, and eliminated it quickly. • TBBPA induced ugt genes expression, which increased T4 metabolism and subsequently induced neurobehavior defects.
Extensive ethnopharmaceutical documentation is available on plants with demonstrated psychoactivity in humans (for review (Raetsch 2005)). Even though there is a huge need for new molecules in mental health, this reservoir of knowledge remains greatly untapped. One of the main reasons is probably the lack of a good in vivo system allowing testing of psychoactive efficacy of complex mixtures of unknown composition. Ethnobotanical reports on a specific plant often differ on plant species/subspecies/harvest but also on mode of preparation and administration which all generate a number of imponderable parameters. Therefore, it is necessary to establish a system which would be capable of circumventing those problems. Ideally, the proposed system has to be flexible and sensitive enough to allow rapid and systematic screening of a big number of complex mixtures like crude plants extracts. In such a system, first pass screening could be done with minimally processed extracts like preparations made from dried powdered parts of a plant of interest. Subsequently, gradually refined mixtures could be tested the same way to eventually isolate the active compound(s).

Normal and visually-impaired zebrafish larvae have differentiable light-induced locomotor response (LLR), which is composed of visual and non-visual components
Zebrafish care The Wild Indian Karyotype (WIK) strain of zebrafish was reared in community tanks on a 14-hour light, 10-hour dark cycle. Fish were fed twice a day, once with formulated feed (Dr. Bassleer Biofish Food) and once with Artemia larvae (cysts from Ocean Nutrition Europe). Eggs were collected 20 minutes after natural spawning and rinsed with system water to minimize infections. Embryos were raised at 28 ± 0.5°C in Danieau's medium. All animal experiments were approved by the Institutional Ethical Committee of the Katholieke Universiteit Leuven and executed in strict accordance with the European Council Directive (2010/63/EC).

As the population grows, so does the drive for urbanization. Urbanization and the resulting anthropogenic activities have an impact on the quality of nearby water resources. Puerto Rico’s population density is one of the highest in the world. We seek to develop a protocol to measure how Puerto Rico´s high level of urban development has impacted the behavior and nervous system function of river fauna. We have started by recording movement trajectory and velocity of freshwater prawn larvae during five consecutive periods of 10-minutes light/dark cycles, using ViewPoint´s Zebrabox.
