4 (3) The Department of Fisheries has revised the standards on Aquaculture Establishment for Export, the Aquatic Animal Stocking Premises for Export and Management Practices for Ornamental fish Farm for Export to combine as a standard on Aquaculture Establishment for Export. This revision is used as a guideline for the aquaculture farmers and entrepreneurs for the improvement of their rearing system to meet the requirements of good sanitary management to be in line with the standard. Therefore, the Agricultural Standards Committee deems it necessary to establish the standard on Good Practices for Aquatic Animal Disease Control in Aquaculture Establishment in order to provide the establishment with good sanitary operation as well as the benefit of healthy and disease free aquatic animals. This standard is based on the following document: The Department of Fisheries. B.E.2543 (2000). The Standard on Aquaculture Establishment for Export. April 2012.
