# Commission Implementing Decision (EU) 2015/1554 of 11 September 2015 laying down rules for the application of Directive 2006/88/EC as regards requirements for surveillance and diagnostic methods (notified under document C(2015) 6188) (Text with EEA relevance), Division I.1: General requirements for inspections and sampling

Extent: E+W+S+N.I.

The sampling of crustaceans for laboratory examination shall be carried out whenever the water temperature is likely to reach its highest annual point. That requirement concerning water temperature shall also apply to health inspections where these are feasible and appropriate.
When farmed crustaceans are to be sampled in accordance with the requirements set out in this Part, the following criteria shall apply:
(a)if weak or moribund crustaceans are present in the production units, such crustaceans shall primarily be selected. If such crustaceans are not present, those selected shall include crustaceans of different size cohorts namely juveniles and adults, of the selected susceptible species, proportionally represented in the sample;
(b)if more than one water source is utilised for crustacean production, susceptible crustacean representing all water sources must be included for sampling.
When targeted surveillance in wild populations is required in accordance with the second paragraph of point 2 of Part I of Annex V to Directive 2006/88/EC, the number and geographical distribution of the sampling points shall be determined to obtain a reasonable coverage of the constituent GB territory, zone or compartment. The sampling points shall also be representative of the different ecosystems where the wild populations of susceptible species are located namely marine, estuary, river and lake systems.
When targeted surveillance in wild populations is required in accordance with the second paragraph of point 2 of Part I of Annex V to Directive 2006/88/EC, the crustaceans to be sampled shall be selected as follows:
(i)in marine and estuary systems areas, one or more of the following species shall be selected: Carcinus maenas, Cancer pagurus, Eriocheir sinensis, Liocarcinus depurator, Liocarcinus puber, Crangon crangon, Homarus gammarus, Palaemon adspersus or penaeid shrimp species namely Penaeus japonicus, Penaeus kerathurus, Penaeus semisulcatus. If those species are not present, the sample must be representative of other susceptible decapod species present. Given the broad susceptible host range, hosts may be selected from genera or families of the Decapoda where susceptibility has been experimentally or naturally demonstrated;
(ii)in river and lake systems, one or more of the following species shall be selected: Pacifastacus leniusculus, Astacus leptodactylus, Austropotamobius pallipes or Orconectes limosus. If those species are not present, the sample must be representative of other susceptible decapod species present. Given the broad susceptible host range, hosts may be selected from genera or families of the Decapoda where susceptibility has been experimentally or naturally demonstrated;
(iii)if weak or moribund crustaceans are present, such crustaceans shall primarily be selected. If such crustaceans are not present, those selected shall include crustaceans of different size cohorts namely juveniles and adults of the selected susceptible species, proportionally represented in the sample.
