The culturist must recognize the .affected fish, collect
representative specimens, prepare them properly for shipment,, and
use the best mode of transportation available. Live specimens are
much preferred to dead ones. The culturist should also provide
adequate information about water quality, culture techniques, and
other factors that may have affected the fish in question. The
fish diagnostician may request further samples from the affected
group, other fish on the station, or a water sample for further
analysis. A good description of correct procedures for the
submission of specimens for disease diagnosis and histological
examination can be found in the articles by Mitchell and Hoffman,
1985 (6) and Yasutake, 1987 (7).
