182. Aquaculture systems should be designed such that disease is minimised.
183. Fish in holding units should be inspected daily by experienced personnel for signs of disease in the stock and any necessary action must be taken immediately.
184. The industry should endeavour to develop better methods of inspecting fish to recognise those which are diseased, distressed or dead.
185. During an outbreak of disease where the cause of death is not immediately apparent, laboratory examination should be carried out to enable treatment to the remaining fish to be initiated.
186. Health certified or vaccinated stock should be used wherever possible.
187. Farmers should practice routine disinfection of equipment and clothing of personnel to reduce the risk of transfer of disease.
188. Leaving sites fallow will reduce the risk of disease or parasite transmission. Management agreements with other operators to fallow wider areas before restocking will reduce this risk level as will information exchange about disease.
189. Stocking density must be kept within manageable levels for the holding facilities.
190. Handling must be minimised so as to lessen susceptibility to disease.
191. Holding units should be cleaned and disinfected once all fish are removed.
192. Different year classes should be kept on separate sites to avoid cross infection.
193. National disease control should be maintained and outbreaks of any serious disease should be reported to the national authority.
