The effect of natural feed, artemia, on the growth of Tiger shrimp post larvae

Abstract

Providing sufficient feed and in accordance with nutrient requirements are required to support the growth of shrimp post larvae. This study aimed to evaluate the growth response of tiger shrimp post larvae fed with natural food of Artemia sp. The PL1 tiger shrimp post larvae test animal at the beginning, with a density of 30 individuals/liter, was maintained until PL12. Using a completely randomized design with three treatments and four replications, i.e., Artemia sp Instar I (treatment A), Artemia sp instar II (treatment B), and a combination of 50% treatments A and 50% treatmens B (treatment C). It showed that treatment A resulted in the best relative length growth rate (7.68%±0.38) and was significantly different from treatment B (6.52%±0.64) and had no significant effect from treatment C (6.88%±0.50). The relative growth rates (RGR) in treatments A, B and C were 44.27%±4.29, 39.58%±4.50 and 38.54%±9.99 respectively and had no significant effect. The use of Artemia sp. instar I and a combination of both provided the best relative length growth compared to the use of Artemia sp instar II, with natural feed consumption levels reaching 95.3% and 94.7%, respectively.
