초록

The survival and growth of Glossaulax didyma didyma (Röding) were measured in the laboratory under controlled conditions (water temperature, salinity and diet). The effect of temperature on G. didyma didyma was examined at four different temperatures (15, 20, 25 and 30℃) with 30 psu for 30 days. The results show that the growth and survival rates of G. didyma didyma were significantly higher at 15℃ and 20℃ than other temperatures. The effect of salinity on G. didyma didyma was also examined at six different salinities (10, 15, 20, 25, 30 and 35 psu) with 20℃ for 40 days. The results show that the growth and survival rates of G. didyma didyma were significantly higher at 30 psu and 35 psu than other salinities. Finally, the effect of diets on G. didyma didyma was examined with three single-component diets (prawn, shellfish and fish) at 20℃ and 30 psu for 60 days. The results show that the growth and survival rates of G. didyma didyma fed on shellfish were significantly higher than those fed on prawn and fish.
