Survival rate was not significantly different among the 3 experimental groups (P > 0.05).

📌 3 Key Takeaways

🎯
Objective & Hypothesis:The effect of different levels of illumination in the early life development stage of sharpsnout seabream (Diplodus puntazzo) larvae was examined.
📊
Key Findings & Data:The difference in the development of total length of the larvae kept in the dark and in other lighting conditions (30-450 lx) was significant (P < 0.05); however, it was determined that digestive tube development, yolk sac utilisation, and oil globule absorption differences of the larvae were not significant (P > 0.05).
💡
Conclusion & Impact:Survival rate was not significantly different among the 3 experimental groups (P > 0.05).

Abstract

The effect of different levels of illumination in the early life development stage of sharpsnout seabream (Diplodus puntazzo) larvae was examined. It was determined that illumination affected the relationships between total length and digestive tube length, total length and oil globule volume, and total length and yolk sac volume. The difference in the development of total length of the larvae kept in the dark and in other lighting conditions (30-450 lx) was significant (P < 0.05); however, it was determined that digestive tube development, yolk sac utilisation, and oil globule absorption differences of the larvae were not significant (P > 0.05). As for the covariance test, while the relationship between total length and oil globule volume was not significantly (P > 0.05) different between Group A (dark) and Group B (30 lx), it was significantly (P < 0.05) different between Group A (dark) and Group C (450 lx), and Group B (30 lx) and Group C (450 lx). Additionally, the relationship between total length and yolk sac volume was significantly different (P < 0.05) between Group A (dark) and Group B (30 lx), Group A (dark) and Group C (450 lx), and Group B (30 lx) and Group C (450 lx) (P < 0.05). However, the relationship between total length and digestive tube length was not significantly different (P > 0.05) between Group A (dark) and Group B (30 lx), Group A (dark) and Group C (450 lx), or Group B (30 lx) and Group C (450 lx). Survival rate was not significantly different among the 3 experimental groups (P > 0.05).
