Zebrafish were assigned to four treatment groups: two received control low-fat diets (LF: low-fat; LFA: low-fat with 5% agavins), while the others were overfed these diets (LFO: overfed low-fat; LFAO: overfed low-fat with agavins). Results indicated that low-fat overfeeding led to weight gain and increased biometric indices indicative of overweight and obesity, alongside notable changes in gut microbiota. Agavin supplementation significantly reduced food intake (p < 0.05) and decreased body weight and fat in the overfed groups. Multivariate analyses (permutational multivariate analysis of variance and analysis of similarities) revealed that the LFAO treatment significantly influenced gut microbiota composition, as assessed through 16S ribosomal RNA gene sequencing (V3 region). Noticeable differences in bacterial composition were observed between LFA and LFAO, especially regarding the genera Aeromonas, Paraburkholderia, and an unclassified genus from the Fusobacteriaceae, which contributed to these differences. While dietary factors, specifically agavins, exerted a limited influence on the composition of gut microbiota, the feeding regimen demonstrated a considerable effect.","PeriodicalId":94273,"journal":{"name":"Zebrafish","volume":"22 4","pages":"141-151"},"PeriodicalIF":1.2,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144877688","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding zebrafish behaviors is important for developing valid models of brain disorders and probing their genetic and environmental causes. The rapid development of zebrafish-based tests and screens also necessitates formal and consistent terminology for the observed phenotypes and behavioral phenomena. To address these needs, in 2013 we compiled a comprehensive 'consensus' glossary of nearly 190 zebrafish behaviors-the Zebrafish Behavior Catalog (ZBC-1) for both larval and adult fish. However, as novel zebrafish behaviors continue to be recognized, an expansion and revision of ZBC were deemed timely. Here, we present the next additional volume of the catalog (ZBC-2), which describes over 120 novel zebrafish behavioral terms and, like the original project, represents a result of a global teamwork of multiple collaborating zebrafish laboratories. Illustrating the value of community efforts to improve data replicability and reliability, this catalog is expected to help interpret research findings, foster cross-domain and cross-species modeling, and encourage new laboratories to study zebrafish behavioral phenotypes.","PeriodicalId":94273,"journal":{"name":"Zebrafish","volume":" ","pages":"117-135"},"PeriodicalIF":1.2,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144805502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The larval stage, on the contrary, is somewhat less used, generally due to a lack of protocols compared with the other stages. In this study, we propose a protocol to study anxiety-like behavior in larvae using the plus maze with ramp (PMR). In the PMR, anxious behavior is measured by the time spent on the flat arms relative to the ramped arms of the apparatus. In the first phase of the study, animals at 5, 14, and 21 days postfertilization (dpf) were exposed to the PMR at different water column heights and session times. It was observed that animals at 14 and 21 dpf were more sensitive to the PMR and exhibited obvious anxiety-like behavior compared with larvae at 5 dpf. In the second phase of the study, to assess the robustness of the type-anxious response exhibited by the larvae, animals at 5, 10, and 14 dpf treated with anxiolytic drugs were exposed to PMR. Alcohol exposure showed a bimodal effect for animals at 10 and 14 dpf, with an anxiolytic effect at intermediate doses, with more exploration of the apparatus and time in the ramp arms. Higher doses caused a reduction in locomotor activity characteristic of drunkenness. Exposure to clonazepam produced anxiolytic effects and a reduction in locomotor activity at the highest dose in 10 and 14 dpf animals. On the contrary, 5 dpf animals showed unexpected effects, which we believe to be related to their stage of development. The results indicate that the PMR is an effective tool for assessing anxiety-like behavior in zebrafish larvae and is sensitive to anxiolytic drugs. Furthermore, anxiety-like behavior appears to vary during the early stages of larval development.","PeriodicalId":94273,"journal":{"name":"Zebrafish","volume":" ","pages":"86-98"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nowadays, this model is increasingly recognized as a valuable tool in other fields, including veterinary medicine and animal production research, particularly aquaculture, due to its unique characteristics that make it suitable for studying economically significant diseases affecting production species. However, unlike established models such as mice, zebrafish lack standardized protocols for housing, feeding, anesthesia, and sample collection, which affects study reproducibility. In addition, it is a common practice to use whole zebrafish larvae or juveniles for metagenomic studies rather than analyzing individual organs, despite the fact that gene expression can vary between organs. This approach complicates the attribution of findings to specific biological processes. To address this, various authors proposed protocols for sample collection in larvae, juveniles, and adult zebrafish; however, comprehensive studies encompassing nearly all fish organs are scarce. Understanding zebrafish anatomy and the technical requirements of the study is essential for accurate sample collection. Some challenges present during zebrafish dissection include the small size of the fish, the fragility of their organs, and the faster onset of autolysis and heterolysis after the death of the animal. Using magnifying lenses, microdissection tools, and conducting dissections on cold surfaces can help mitigate these issues. This article aims to improve sample collection for histopathological and genetic studies in adult zebrafish by establishing a comprehensive, organized, and systematic dissection protocol that accounts for the anatomical specifics of this experimental model.","PeriodicalId":94273,"journal":{"name":"Zebrafish","volume":" ","pages":"76-85"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144049414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we report a novel imaging technique using a recently developed clearing reagent called LUCID that makes it possible to capture the complete cellular-resolution 3D structures of larval and juvenile zebrafish. We show that LUCID clears dense tissues such as pharyngeal cartilage in juvenile animals and even tooth bone in adults without causing either significant morphological distortion or significant loss of signal from transgene-driven fluorescent proteins, fluorescent nuclear DNA or actin staining dyes, or whole-mount in situ hybridization chain reaction fluorescence.

Although commonly utilized, immersion anesthesia presents a shortcoming of lethal asphyxiation with increased duration of exposures. A newer technique that circumvents this issue, known as flow anesthesia, has been adapted from larger aquatic species to zebrafish. Flow anesthesia improves safety by delivering oxygen-rich water along with the anesthetic across gill epithelium and allowing fish to be manipulated outside of water. Information on the construction of flow anesthesia apparatuses and parameters are sparse. The goal of this study was to create a flow anesthesia apparatus with materials commonly found within a research facility and to evaluate variable concentrations of MS-222 for anesthesia in zebrafish. Depth of anesthesia was monitored by quantifying respiratory rate and recording responses to physical stimulation. All concentrations of MS-222 evaluated (30-100 ppm) were successful at maintaining surgical anesthesia for up to 30 min. The anesthetic events were demonstrated to be safe, with an observed 97% survival rate.

Viability assessments were conducted on oocytes at various developmental stages using LIVE/DEAD and the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) reduction assay. For sperm evaluation, both kinetic (computer-assisted sperm analysis) and morphological assessments (Rose Bengal staining) were performed. Results demonstrated that rigor mortis progression significantly impacted oocyte viability during post-rigor stages, with the following viability rates: pre-rigor (70.43 ± 12.31%), fresh/control (46.43 ± 12.54%), post-rigor (27.62 ± 22.29%), and rigor mortis (comparable to fresh/control). Conversely, sperm kinetics exhibited nuanced responses to the rigor mortis stages, with specific parameters showing sensitivity, whereas the others remained relatively stable. Sperm motility was higher in the fresh/control (63.23 ± 19.03%) and pre-rigor (58.96 ± 14.38%) compared to the post-rigor group (3.34 ± 4.65%). This study highlights the significance of the pre-rigor for successful gamete collection and preservation.
