Site 0 (S0), parasites present in both hypaxial and epaxial musculature.
Site 1 (S1), no parasites in hypaxial musculature but present in epaxial musculature.
Site 2 (S2), parasites present in hypaxial musculature but absent in epaxial musculature.
Site 3 (S3), no parasites detected in either hypaxial or epaxial musculature.
Abundance 0 (A0), with pathological changes and parasite morbidity.
Abundance 1 (A1), with pathological changes or parasite morbidity.
Abundance 2 (A2), no visible lesions, discoloration, or tissue damage in muscle.
Density 0 (D0), heavy infection (higher than the 5 parasites/kg of fish).
Density 1 (D1), light infection (2-5 parasites/kg of fish).
Density 2 (D2), very light infection (<2 parasites/kg of fish).
Epidemiology 0 (E0), zoonotic or potentially zoonotic species.
Epidemiology 3 (E3), non-zoonotic species.
