英文摘要	The welfare of farmed fish is an important issue in aquaculture. There is particular concern regarding ambient light in culture systems. In the current study, turbot (Scophthalmus maximus) larvae were exposed to four different light spectra: full spectrum (LDF), blue (LDB, peak at 450 nm), orange (LDO, peak at 595 nm) and red (LDR, peak at 629 nm) from the embryo stage to 60 days post hatching (dph). During this time, the growth and immune response of the turbot were evaluated. Whole fish tissue samples were collected and weighed. mRNA expression levels of insulin-like growth factor-I (IGF-I), heat shock protein 70 (HSP70), glutathione S-transferase (GST), catalase (CAT), metallothionein (MT), lysozyme (LZM), cathepsin D (CTSD), cathepsin F (CTSF) and the enzyme activity of superoxide dismutase (SOD), CAT, and peroxidase (POD) were measured at 10, 20, 30, 40, 50, and 60 dph. The results showed that LDB had a positive effect on the growth of turbot larvae at 20, 40, 50 and 60 dph, while this effect was not significant at 10 and 30 dph. Levels of IGF-I mRNA also showed a similar tendency, indicating the crucial interaction between IGF-I and somatic growth. The effect of light spectrum on the stress response of turbot larvae was stage specific. At 10 dph, prior to metamorphosis, long wavelengths could induce a stress response in turbot larvae. At 20 dph, metamorphosis began and no significant stress response was observed in larvae exposed to different light spectra; however, LDO significantly up-regulated SOD, CAT, POD and LZM activity. Metamorphosis continued until 56 dph. From 20 to 60 dph long wavelengths (LDR and LDO) resulted in a stress response characterized by high mRNA expression levels of HSP70, GST, CAT, MT, LZM, CTSD and CTSF. SOD, CAT, POD and LZM activities were inhibited, indicating increased enzyme consumption to maintain homeostasis. Overall, our results suggested that LDF should be used in turbot culture systems prior to metamorphosis and LDB should be used after metamorphosis. These findings are in keeping with the changes in light spectra experienced by turbot larvae undergoing metamorphosis in the wild.
