Asian seabass propagated in a hatchery showed some anomalies in development and morphological features. The mouths of 1% of the hatchlings did not open after 72 hours, although their yolks were completely exhausted. None of these fry survived beyond 75 hours. Two other distinct anatomical abnormalities occurred together: upward bending of the caudal fin and thickening at the base of the distal end of the second dorsal fin. The deformed caudal fins also differed from normal fins in the number of fin rays. These anomalies were probably linked to inbreeding and could have a genetic basis.
