"This must be the best invention since sliced bread! We might get a bonus this year thanks to the Flexi-Panel."

Atlantic Salmon of Maine
USA

 

Sizes/Uses

The direct financial benefit of using the Flexi-Panel to size grade farmed salmon prior to harvest can clearly be seen in the following example, which is taken from actual harvest results in May 2002.

The farmer required to harvest approximately 40 tonnes of salmon out of a cage containing approximately 200 tonnes.

There were two options;

Harvest a large number of ungraded fish to give the required tonnage.

Size grade the fish, harvesting only the larger grades, thereby requiring less fish to give the same tonnage.

Note: Larger size categories fetching a higher price per Kg.

RESULTS:

Option 1: 13,616 fish harvested (ungraded) value £ 45,772

Option 2: 9,892 fish harvested (large graded) value £ 59,854

Benefits of size grading prior to harvest:

£14,082 EXTRA income to the farmer for harvesting 3724 LESS fish.

And the benefits don't stop there; by grading out a lesser number of larger fish you still have many more small fish available to grow on to the optimum size, thereby ensuring that you can produce the maximum tonnage of fish at the best possible prices.

The wider benefits of using the Flexi-Panel include the following:

  • The Flexi-Panel is very light and easy to use compared to
    rigid graders.
  • The grading operation is very quick and simple to carry out
    even with large cages and large tonnages of fish.
  • The larger the size of grading panel the quicker the grading
    operation is completed therefore the less stress is put on the fish.
  • The large dominant fish are selected for harvest.
  • Small fish are not harvested and are therefore grown on to
    a larger size.
  • Continuity of supply of the correct size of fish can be achieved.
  • Growth rates are increased as the density is reduced.
  • The FCR is lowered by always selecting fish for harvest at the
    optimum size.
  • The lower FCR means that you can achieve lower production costs.
