In the intensive culture of fish an understanding of indicators of fish egg quality is important. Eggs of Japanese sea bass frequently are observed to have multiple oil globules; however, quality of these eggs relative to eggs with a single oil globule is not known. This paper describes development of Japanese sea bass eggs with multiple oil globules: developmental changes in the percentage of multiple oil globule eggs, oil volumes, hatching rates and the anomaly rates in eggs and larvae. Early blastula-stage eggs had 1-15 small oil globules and the percentage with multiple oil globules varied from 30.9 to 100% depending on batches. Fusion of oil globules occurred during the optic vesicles stage and in most cases number of globules decreased from multiple to single by 1-3 hours before hatching. Volume of oil in single oil globule eggs was essentially the same as the sum of integrated volumes of all small oil globules present during the early blastula stage. Morphological features of 50 larvae/day hatched from multiple oil globule eggs were observed from hatching to 14 days after hatching. Hatching rates from multiple oil globule eggs were high (ca. 80%) and the number of anomalous newly hatched larvae was negligible (ca. 5%). Two anomalous larvae were observed with one oil globule in the body cavities 7 and 13 days after hatching. These results suggest that multiple oil globules eggs of Japanese sea bass can be useful for intensive seedling production.
