Wet feedstuffs used as binders for probiotics and other feed additives in top-coating or top-dressing applications are allowed.

Wet feedstuffs can be used as carbon sources for water quality control i.e., anaerobic fermentation or biofloc technology.

Records:

Wet feedstuffs, moist pellets, or uncooked/ unprocessed fish are not used by the UoC by cross-checking records with observations and personnel interviews.

Although the science behind prion diseases, infectivity and pathogenicity in fish in association with Transmissible Spongiform Encephalopathies (TSEs) is not very well developed, ASC has taken a precautionary approach and followed the guidelines of FAO (2011) Aquaculture Development. 5. Use of Wild Fish as Feed in Aquaculture Principle 9.1 “For biosecurity reasons, intraspecies recycling is an unacceptable practice that should be prohibited”.

Protein hydrolysates verified to <10,000 daltons are allowed as controlling the molecular weight provides a good verification of the appropriateness of an applied transformation process. This is in line with Regulation (EU) 142/2011 regarding the use of animal by-products.

Regulated source means that there are national/international laws, agreements or policies governing the harvesting or farming of seaweed and that these are complied with, or the seaweed is from a certification scheme which addresses the responsible management of seaweed, whether wild-harvested or farmed.

Seaweed certified to the following standards meet this ASC requirement on regulated sources:

Legislation which stipulates responsible harvesting or farming.

Supplier harvesting or farming permits.

Certification documentation.

Legislation which stipulates responsible harvesting or farming.

Presence and validity of permits.

ASC-conforming compound feed is sourced from feed mills certified to the ASC Feed Standard.

This requirement does not apply to non-certifiable species (e.g., cleaner fish).

Documented process to confirm feed is ASC-conforming that includes verification of (see Indicator 1.4.3):

Records of regular litter collection activities and the responsible disposal of any items recovered.

Regular litter collection activities have taken place.

Alternatively, conduct a visual inspection to demonstrate low levels of waste are present on the receiving shoreline or land surrounding the site.

The site should develop a maintenance plan that identifies the schedule for regular maintenance of machinery, aquaculture gear and infrastructure.

The person(s) conducting maintenance should have an adequate level of competence based on the type of maintenance required.

Maintenance plan that identifies the schedule for regular maintenance of machinery, aquaculture gear and infrastructure.

Records to demonstrate maintenance was performed according to the schedule outlined in the maintenance plan.

Written justification should be in place in cases of deviation from the schedule outlined in the maintenance plan.

The site has a maintenance plan covering regular maintenance of machinery, aquaculture gear and infrastructure.

Records that the schedule has been adhered to.

An appropriate effluent treatment should be able to eliminate or reduce to acceptable levels the discharge of (amongst others):

An effluent monitoring plan appropriate for the type and amount of processing effluent discharged.

Including the parameters, frequency of monitoring and acceptable limits.

Analysis results of the parameters included in the effluent monitoring plan.

Corrective actions when analysis results exceed acceptable levels.
