This kit includes all the essential tools for observing fish prey, housed in a medium-sized waterproof case. The stomach pump features two interchangeable nozzle lengths that can be adjusted to match the size of the fish. A gridded tray with a neutral gray scale makes specimens easy to photograph and ideal for documenting seasonal prey data. This all-in-one observation kit also includes a loupe and tweezers for detailed inspection, along with five insect bottles for safely storing collected samples.
