- Abstract
The article discusses a study which determined the developmental changes in the cone density distribution, visual axis and minimum separable angle of cones during growth of juvenile Pacific bluefin tuna Thunnus orientalis. The study used specimens of Pacific bluefin tuna from six stages that were full-cycle cultured during 2003-2004 in the Fisheries Laboratory, Kinki University in Wakayama, Japan. The study showed that the region of maximum cone density, that is, the area centralis, gradually developed in the ventro-temporal area with growth during the first 80 days after hatching.
