KeywordsĪlava VR (1998) Effect of salinity, dietary lipid source and level on growth of milkfish ( Chanos chanos) fry. Juvenile golden pompano can be reared above 26‰ without affecting fish performance, and the salinity <18‰ is not suitable for the growth of juvenile golden pompano. The lowest activity of Na +K +-ATPase was obtained in fish at 34‰, while the highest activity of Na +K +-ATPase was obtained when fish at 18‰. The activities of SOD of fish reared at 18‰ and 34‰ were significantly higher than those reared at 10‰ and 26‰. The GPX activity was highest when the salinity was 26‰ and lowest when the salinity was 34‰. The FCR of fish cultured at the salinity of 10‰ was five times higher than the FCR of fish reared at 34‰. Raising salinity has significant effects on FCR of juvenile golden pompano.
The α-amylase activity of fish reared at the salinity of 10‰ was significantly lower than fish at the salinity of 34‰. However, rearing salinity had a significant effect on α-amylase activity. The effect of salinity on pepsin activity was not significant. When the salinity was 34‰, the fish growth rate and RNA/DNA ratio were higher. Rearing salinity significantly affected fish growth and the RNA/DNA ratio. This chapter discusses the salinity to the juvenile golden pompano Trachinotus ovatus (Linnaeus 1758) rearing performance impact.
The physiological status of euryhaline teleost is regulated by environmental salinity through different mechanisms.
