摘要：The study aimed to evaluate the utilization of seaweed Caulerpa racemosa as feed ingredient for tiger shrimp
Penaeus monodon. This research consisted of two different stages, i.e. digestibility and growth test. Tiger shrimp
with average body weight of 5.70 ± 0.42 g was reared during digestibility test. The measured parameters were
total protein, calsium, magnesium, and energy digestibility. The growth test was managed by using a completely
randomized design consisted of four different treatments (in triplicates) of dietary C. racemosa meal addition
levels, i.e. 0 (control), 10, 20, and 30%. Tiger shrimp with an average body weight of 0.36 ± 0.02 g were cultured
for 42 days in plastic containers (70×45×40 cm) with a stocking density of 15 shrimp/container. Apparent dry
matter, protein, calcium, magnesium, and energy digestibilities of C. racemosa were 51.82, 88.67, 68.44, 16.39,
60.30%, respectively. The results presented that the growth performance of tiger shrimp fed with diet containing
10% of C. racemosa was not significantly different with the control (P>0.05). However, the growth performance of
the shrimp fed with diet containing more than 20% of C. racemosa decreased. The enzyme activitity of superoxide
dismutase (SOD) increased with the higher level of dietary addition of C. racemosa. It can be concluded that C.
racemosa was possibly applied up to 10% in the feed formulation for tiger shrimp.
