Description
The Aotracell Plunger/Stirrer is a custom-made acrylic tool for oyster hatcheries. Gentle up-and-down strokes spread larvae evenly through the water column without harming them, so the sample you draw for larval counting gives an accurate density estimate.
Features
- Custom-made from clear, durable acrylic
- 19.4 cm plunger diameter, suited to larger larval rearing tanks
- Smooth surfaces that are gentle on larvae and easy to rinse clean
- Made for homogeneous mixing before sampling and counting
How to use
Plunge slowly up and down several times until the larvae are evenly spread, then take your sample straight away for counting. Rinse with fresh water after use.
