Product quality

Parasites:

Products should be secured 100% free of parasites. 

Intake water for fish farm needs to be either a bacteria/pathogen free and parasite free subsoil intake, or alternatively all intake water to the farm needs to be either pasteurising or treated by a combined treatment of a screen filtration to 30 micron, followed by a UV treatment, with a dose of minimum 120000 MWS. Insed production unit, minimum one exchange of fish tank water volume per hour, and all inlet of water to fish tank filtered to a maximum mesh size of 50 micron. If water is reused, then filtration is still required on each lupe/ return of water to fish tank.

Purging:

Minimum 5 days of purging before harvest.

Concentration of geosmin in purge water: max. 8 ng/l

 

Stress

Water velocity in fish production tanks:

Salmonides: min 30% of body length per sec. average in water column.

(Water velocity has impact on flesh quality – structure and oil content - on especially salmonides.)

Methods should be applied to minimise stress on fish in general, and 10 days up to harvest indeed.

Grading not permitted the last 15 days before harvest.

Use of antibiotics are not allowed in production facility. Fish cannot be sold as ORG.SEA fish for 6 months after any treatment of fish in the facility. (A facility is considered as a separate production unit, with individual UV treatment of intake water, and bio-security zone between any other production units.

 

Traceability:

Any batch of fish should be traceable from eggs to harvest. A maximum of 2 batches (from eyed eggs) can be pooled in the same tank unit/section.

Data logging/records

Logging per tank:

Feed, type and amount (daily)

Oxygen (hourly)

Water velocity (2 x weekly)

Central inlet and outlet to tanks within facility:

pH, Hourly

CO2 (2 x weekly)

Ammonia (2 x weekly)

Nitrate 2 x weekly

Nitrite 2 x weekly

Geosmin monthly

All logged data have to be stored for a minimum of 36 months.

 

Feed

Minimum 50% of product in fish feed or of actual fish feed applied at facility (ORG.SEA fish produced), has to be of organic or a sustainable source.

For the last 30% of the weight increase of the fish, minimum 70% of the feed applied to the fish should be certified as organic.

The feed criteria will be under constant evaluation, but the OSC standard is balancing the fish welfare and product quality, against the demand of feeding the fish on organic feed.

Still of today truly organic feed would not satisfy the nutritional requirement of the fish.

OSC consider organic fish feed, a feed where minimum 95 % of the Ingredients comes from a fully controlled organic source.

Ingredients, which have origin from wild populations of fish, are in this sense not an organic source.
