The ZE-Tunnel: An Affordable, Easy-to-Assemble, and User-Friendly Benchtop Zebrafish Swim Tunnel.
The popularity of zebrafish in both basic biological and biomedical research has led to an increased need for understanding their behavior. Locomotor behavior is an important outcome of different factors, such as specific genotypes or external stimuli that influence the nervous and musculoskeletal system. Locomotion can be studied by forced swimming in a swim tunnel, a device capable of generating a laminar water flow at different speeds in a chamber where zebrafish can be placed. However, commercially available swim tunnels are relatively expensive and in-house built systems are mostly presented without clear building instructions or proper validation procedures. In this study, we developed an alternative, cheap (<250 euro), and user-friendly, but customizable benchtop swim tunnel, called the "Zebrafish exercise-tunnel" (ZE-Tunnel). Detailed step-by-step instructions on how to construct the tunnel components, including the frame, mechanical, and electric components are given. The ZE-Tunnel was reliably used to exercise fish for prolonged periods and its performance was successfully validated by replicating previously published experiments on critical speed testing in zebrafish. Finally, implementation of behavioral video analysis using freely available motion-tracking software showed differences in swimming dynamics in the Chihuahua skeletal zebrafish mutant.
期刊介绍:
Zebrafish is the only peer-reviewed journal dedicated to the central role of zebrafish and other aquarium species as models for the study of vertebrate development, evolution, toxicology, and human disease.
Due to its prolific reproduction and the external development of the transparent embryo, the zebrafish is a prime model for genetic and developmental studies. While genetically more distant from humans, the vertebrate zebrafish nevertheless has comparable organs and tissues, such as heart, kidney, pancreas, bones, and cartilage.
Zebrafish introduced the new section TechnoFish, which highlights these innovations for the general zebrafish community.
TechnoFish features two types of articles:
TechnoFish Previews: Important, generally useful technical advances or valuable transgenic lines
TechnoFish Methods: Brief descriptions of new methods, reagents, or transgenic lines that will be of widespread use in the zebrafish community
Zebrafish coverage includes:
Comparative genomics and evolution
Molecular/cellular mechanisms of cell growth
Genetic analysis of embryogenesis and disease
Toxicological and infectious disease models
Models for neurological disorders and aging
New methods, tools, and experimental approaches
Zebrafish also includes research with other aquarium species such as medaka, Fugu, and Xiphophorus.
