Indicator 2.6.3

Indicator 2.6.3 complements the other water quality indicators by addressing the direct release of uneaten feed in the form of fines into the environment.
Setting a maximum percentage of fines in the feed addresses the efficient and proper transport, storage and physical delivery of feed pellets to the site.
Poor performance in any of the above phases of feed handling will result in a higher percentage of fines (fine particles of feed) and potentially greater impacts on water quality, due to an increase in suspended organic particles and nutrients released into the environment.
Sampling of feed lots includes feed delivered as material in bulk, big bags and small bags to the site.
Testing by the feed manufacturer to the UoC is permissible where there is no significant risk of feed deterioration during subsequent handling, storage or application.
- The UoC should demonstrate that deterioration in feed does not take place during the processes outlined above.
- The UoC should report the schedule and location of testing of feed if it is not conducted on-site.
Rationale for not testing on site should also be reported.

The method used to determine the percentage of fines in feed, in accordance with Appendix 8 (8.3).
The determination and documentation of a schedule and location for the testing of feed.
If testing takes place prior to delivery to the site, the rationale should be documented for not testing on site.
Calibration of sieving machines (if used) in accordance with the manufacturer’s recommendations.

The rationale for the timing and location of feed sampling.
The UoC has appropriate testing technology on site and that, if applicable, it is calibrated as required.
The method used to determine the percentage of fines in feed, in accordance with Appendix 8 (8.3).
Review testing results and confirm that results demonstrate feed contains <1% of fines.
