Aquaculture Crayfish Behavior & Fighting Recognition

A camera above a crayfish tank spots fighting, attacks on soft-shell moulting animals and the male to female ratio, all on the camera itself. Only alerts and small image crops leave the device. It is for recirculating tank farms, broodstock units and aquaculture researchers.

95.0%: fight recall on reCamera Pro (vendor benchmark on a real aquaculture dataset)
90.5%: false overlap alerts correctly rejected (same benchmark)
66 ms: trigger to MQTT alert on the device
82.0%: top-1 sex classification accuracy

Results reported by the design's authors on their own test setups. Yours depend on the site, so we confirm them in a pilot.

The problem

Why it matters.

Crayfish fight and eat soft-shelled molting tankmates, and farmers cannot watch tanks all day to catch it or track sex balance.

The flow

From signal to action.

01SenseTank cameraA reCamera mounted overhead or at 45 degrees films the tank at 10 to 15 FPS.
02DecideDetect and trackEach crayfish is found and given a track ID on the camera's NPU.
03DecideProximity triggerWhen two animals come closer than 1.1 body lengths, that region is cropped.
04DecideFight checkEight frames of the crop are checked together to tell real contact from visual overlap.
05ConnectAlert outStart, change and end events go to a local MQTT broker for the farm dashboard.

How it works

Step by step.

01Mount the camera 0.8 to 1.5 m above the tank, or at a 45 degree angle, with diffuse lighting.
02Connect it to the local network, using PoE on the reCamera 2002.
03Deploy the reference design and point it at your MQTT broker.
04Let it count animals and estimate the sex ratio from the first frames of each track.
05Receive fight alerts and snapshot crops on the dashboard or Home Assistant.

Before you install

A fixed mount 0.8 to 1.5 m above the tank or at 45 degrees.
Diffuse lighting with no strong glare on the water surface.
Reasonably clear water; very turbid tanks are not supported.
A local MQTT broker on the farm network, and PoE if using the reCamera 2002.

Good to know

Heavy reflections and very murky water create blind spots.
Sex ratio figures carry the classifier's error, so treat them as estimates.
Other species need retrained detection weights and new aggression thresholds.
Dead animals produce no fight events, so it is not a mortality monitor.

How we deliver it

Paper to site, one team.

01Site surveyWe walk the site, or review photos and drawings, and agree what to measure and where each device goes.
02PilotOne lane, one line or one room first. We tune it on your conditions and agree what good looks like.
03Roll outWe supply the hardware in India with GST invoices, install it, and connect it to the systems you already run.
04SupportSpares, remote checks and model updates, with one team to call when something changes.

Questions

Asked before buying.

Does it need internet at the farm?

No. Detection runs on the camera and alerts go to a local MQTT broker.

Can it be used for prawns or fish?

The method carries over, but the detection model must be retrained and thresholds tuned for the new species.

Does video get uploaded anywhere?

No. Only alerts and small cropped snapshots leave the camera.
