Pelagic Grading

Ensuring that our customers receive fish graded to their exact size requirements is a top priority at New Sea ApS. Proper grading is essential not only for meeting customer expectations but also for ensuring efficiency in processing, packaging, and use.

Fish are graded by size based on body length, weight, and count per kilogram. This system helps maintain uniformity and consistency across shipments, making it easier for customers to plan their operations and meet market demands. The grading system used for Mackerel and Horse Mackerel in Africa is well-established and standardized, as outlined in the table below.

How Fish Are Graded

1. Body Length
The fish’s body is measured from the tip of the mouth to the base of the tail (as shown in the diagram below). This measurement helps categorize the fish into different size grades, such as Large (L), Medium (M), Small (S), and so on.
2. Weight
Each size category corresponds to a typical weight range. Fish graded as Large (L) will weigh 333 grams and above, Medium (M) ranges from 143 to 333 grams, and Small (S) ranges from 111 to 166 grams. These standardized weight ranges ensure consistency and allow customers to plan based on predictable quality.
3. Count per Kilo or Carton
The count per 10 kg or 20 kg carton is another important aspect of grading. Larger fish will have fewer pieces per kilogram, while smaller fish will have more. For instance, a carton of Large fish (L) may contain 20–60 pieces per 20 kg, Medium fish (M) may contain 60–120 pieces per 20 kg, and Small fish (S) may contain 120–180 pieces per 20 kg. These counts ensure uniformity, making it easier for buyers to assess and plan their purchase quantities.
4. Standardized Categories for Africa
In African markets, fish are typically sold under standardized sizes, such as L (25+ cm), M (20+ cm), S (16+ cm), SS (14+ cm), and SSS (12+ cm). These sizes help buyers and sellers communicate clearly and ensure that expectations are met.

At New Sea ApS, we take great care to ensure that our packers follow these standard grading practices. This helps us maintain consistency across shipments and ensures that the fish meet the quality and specifications required by our customers.
