Fish grading table

In small to medium size grow out operations, grading fish from 20 to 200 grams per piece is easy using a grading table. Fish is brought on the table and is graded by hand and on sight. The grading table, constructed of waterproof multiplex, is placed on an easy to clean stainless steel stand.

Automatic fish grading equipment

For medium or large size nursery and grow out farms automated fish graders are essential. These graders have a high flow rate, reducing the impact on the fish, but increasing efficiency. These machines can grade up to 4 different size classes at once and can be equipped with automatic fish counters. Aquaculture ID can supply the right automatic fish grader with optional equipment fit to your operations.
