USE OF SPONGE, Callyspongia basilana EXTRACT AS ADDITIVE MATERIAL ON TIGER SHRIMP CULTURE
Abstract: Blue shrimp disease
is one of the main problems in tiger shrimp culture. It reduces shrimp quality
which eventually will decrease its market price. Blue shrimp is caused by
deficiency of nutrition and additive materials such as carotene and other
nutrient which function as vitamin source for important metabolic processes and
formation of color profile in shrimp and fish. The aims of this study were to
study the application effect of carotenoid extract of sponge Callyspongia
basilana, as an additive material on the ability of shrimp to get back to
normal state after suffering blue shrimp disease and survival rate of shrimp
and to find out the optimal concentration of sponge carotenoid extract to cure
the diseased shrimp. This study was consisted of two steps namely; (1).
Extraction of sponge carotenoid by maseration and fractionation using acetone
and petroleum ether solvents and (2), the application of carotenoid extract on
the diseased shrimp. The research was arranged in a complete randomized design
with four experiments consisted of (A). Control (without carotenoid extract);
(B),(C), and (D) carotetoid extract addition of 3 mg/L, 6 mg/L, and 9 mg/L
respectively with three replication each. The test animal used were blue
diseased tiger shrimp with the density of 15 ind./container having 7.5–9.5 cm
in size and the average weight of 5.5–10.0 g. The study showed that
Callyspongia basilana carotenoid extract was able to change blue diseased
shrimp to be normal within six days at the concentration of 9 mg/L. The highest
survival rate was found in the experiment D (93.3%). Meanwhile, the lowest was
obtained by the control population (13.3%) and the other two treatments were
80.0%(C) and 73.3% (B). The average of water quality parameters such as
temperature, dissolved oxygen, pH, salinity, nitrite, and ammonia were in the
suitable range for the growth and survival rate of tiger shrimp.
