Custom Aluminum Retention Cage

with Knotless Mesh Net and Zipper Access

– For Live Fish Holding, Measuring & Tagging

Our aluminum retention cage with integrated zippered net is designed for biologists, researchers, fisheries technicians, and aquatic science professionals who need a reliable solution for temporary live-fish holding during measuring, tagging, sampling, or scientific evaluations.

We offer full custom manufacturing, both for the aluminum frame and the net cage. The net is most commonly made using knotless mesh, which is softer, safer for fish, and highly durable. This design reduces abrasion, stress, and injuries while ensuring excellent water flow for optimal fish health. Mesh size, cage dimensions, access system, and overall configuration can all be tailored to your requirements.

The reinforced zipper entry enables fast, secure access for biometric measurements, marking operations, visual inspections, sorting, and transferring fish. Its efficient water exchange capacity helps maintain oxygenation and vitality throughout the holding period.
