Zookeeper Lionfish Containment Unit

Overview

The ZooKeeper Lionfish and Marine Debris Containment Unit is an underwater collection container for speared lionfish, other edible catch, and marine debris while limiting direct hand contact with the contents. Its slotted funnel and one-way entry allow spear-loaded catch to be transferred into the chamber and retained during the dive.

Loading and containment

After a lionfish is speared, the diver guides the spear through the slotted funnel so the fish can be transferred into the chamber without removing it by hand. Once the catch passes through the entry, the one-way mechanism keeps it inside so hunting can continue without reopening the container.

Flow-through safety design

The puncture-resistant containment body is designed to keep lionfish spines enclosed while water moves through the unit. At the rear, the safety drain valve permits water passage while helping prevent contained spines from protruding through the drain area. Negative buoyancy supports controlled handling underwater.

Choosing a configuration

The family includes fixed-length and expandable configurations. Expandable versions increase usable length and catch capacity beyond their base size, while fixed-length versions retain a rigid form. Selection should account for expected catch volume together with carrying, travel, and storage space.
