The Stocker Difference

Why Hatcheries Choose the Stocker

It does one thing, and it does it brilliantly. No touchscreens to calibrate, no software to update — just load fish and read the count.

Set-and-Forget Counting

No training required. Load fish into the hopper, and the optical sensor does the rest. The count displays in real-time on a clear digital readout. Reset with one button.

Built for Daily Use

Robust construction that handles the wet, the messy, and the repetitive. Corrosion-resistant components, sealed electronics, and a design that shrugs off the hatchery environment.

Right-Sized for Your Operation

Two models, zero guesswork. Stocker1 for fingerlings and smaller stock (0.7–10 cm). Stocker2 for larger grading and grow-out (2–25 cm). Pick the throughput that matches your volume.

FAQ

Common Questions

QWhich Stocker model do I need?

It comes down to fish size and volume. Stocker1 handles fingerlings and smaller stock from 0.7–10 cm at up to 200K/hr. Stocker2 covers larger grading and grow-out from 2–25 cm at up to 300K/hr. If you're counting fingerlings or fry, Stocker1. If you're stocking grow-out ponds with larger fish, Stocker2.

QHow accurate is the Stocker really?

>99% accuracy under normal operating conditions. The optical sensor counts each fish as it passes through the channel. Accuracy can be affected by extremely high flow rates or fish clustering — maintain a steady, even feed for best results.

QIs it difficult to set up and operate?

That's the whole point — it isn't. No touchscreen calibration, no software updates, no complex menus. Load fish into the hopper, read the count on the digital display, and press one button to reset between batches. If you can turn it on, you can use it.

QCan the Stocker handle saltwater species?

Yes. The Stocker uses corrosion-resistant components and sealed electronics rated for both freshwater and saltwater environments. Rinse after use in saltwater to maximise component lifespan.

QWhat happens if the counter miscounts?

Miscounts are rare at >99% accuracy. The most common cause is overloading the hopper or feeding fish too quickly. Maintain a steady, even flow and the optical sensor delivers consistent results. If you ever need to verify, the one-button reset lets you recount immediately.
