Abstract

• 65 days feeding trial
• 0% (control), 13%, 25%, 37%, 48%, 68%, 85% and 100%.
• Increasing weight growth performance
• Increasing immune index
• 29.1% of replacement has the best effect on growth and immune index
• could partially replace the fish meal

MATERIALS AND METHODS

Six day old BSFL was collected at the first day as it appearance of pre-pupae.

Results

Category	Higher	Lower	Normal	Notes
Growth performance	T13%, T25%, T37% and T48%
Feed Conversion Ratio		T13%, T25%, T37% and T48%		Not Significant
Protein productive value	T13%, T25%, T37%, T48% and T68%			Not Significant
crude lipid	T37% and T48%
LZM activity		T68% and
T100%

Discussion

• 25% of the replacement has the best effects on the fish.
• replacement is up to 48%
  • This agree with up to 45% replacement in juvenile European seabass(Magalh~ aes et al., 2017).^[1]
  • yellow mealworms meal could only replace 18% of the FM diet.(Su et al.,2017)^[2]
• The value of Lue is higher than previous studies.
• Chitin might influence the feed intake, availability and digestibility of the nutrients and growth performance of the fish (Cummins et al., 2017)^[3]
• Increasing the immune index, might casued by the Chitin
• Chitin may also responsible to the decrease of the palatable.
