摘要
Two groups of juvenile sea-bass, a random group and a group selected on the criteria of the appearance of macroscopically visible body deformations or anomalies in behaviour, were collected from the rearing tanks, treated for cartilage-bone staining with alizarin and alcian-blue, and examined for osteological abnormalities. The meristic characters of the stained specimens were also examined. The percentage occurrence and the interrelationship of the various abnormality types are described. The most frequently encountered abnormalities were those involving spinal column and vertebral deformities and these were often associated with swimbladder deficiencies.
