Aquaculture quality control · Marexi

Automatic real-time detection and separation of deformed aquaculture fry.

Aquadef® is the first automatic system to detect and separate deformed fry in real time. It counts, measures and segregates batches by size simultaneously — eliminating human error at the most critical stage of aquaculture production.

Aquadef® — automatic fry quality control system
Malformation detection

Four computer vision algorithms.

The system simultaneously analyses four key anatomical zones of each fry, detecting the most frequent and clinically relevant malformations in aquaculture production.

Operculum

Detects exposed gill using colour coordinates, identifying fry with anomalous opercula that are vulnerable to infection and respiratory stress.

Snout / Mouth

Detects incorrect mouth angle via silhouette analysis, identifying malformations that impair efficient feeding and reduce fry survival rates.

Spinal column

Detects angular changes in the fish silhouette to identify spinal deviations (scoliosis, lordosis, kyphosis) affecting development and feed conversion.

Dorsal fin

Detects angular changes in the dorsal silhouette zone, identifying fin malformations that are early indicators of structural problems in the fry.

Capabilities

More than detection — complete biometric control.

Detection & separation

Detects and physically separates deformed fry in real time, with no manual intervention. Continuous process matched to production rate.

Precision counting

Counts fry with high precision during the process, providing accurate batch population data for inventory management and cultivation planning.

Size & average weight

Measures individual size and calculates average batch weight, generating biometric profiles that enable feed and growth optimisation.

Size segregation

Segregates batches by size into separate channels simultaneously, reducing intraspecific competition and improving culture homogeneity and survival.

Automated reports

Generates detailed batch reports with biometric and morphological data, malformation percentages by type and standardised production statistics.

Remote assistance

Internet connectivity for real-time international technical assistance. Low maintenance with remote software updates.

Business impact

Cost reduction across the cultivation chain.

Early elimination

Removing unsuitable fry early avoids the cost of feeding, treating and maintaining them in tanks until the problem becomes visible to the naked eye.

Tank optimisation

Lower density of non-productive animals reduces costs of water volume, feed and treatments, and shortens transition times between cultivation phases.

Stock quality

Homogeneous, deformity-free batches show higher survival, better feed conversion and greater commercial value in subsequent production cycle stages.

Standardised QC

Acceptance criteria are defined by the client and applied objectively and reproducibly, eliminating variability from human judgement in fry selection.
