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.

Sponge global demand for industry and research needs far exceeds supply from the sea. Aquaculture is considered as the only viable method that can supply sufficient and sustainable quantities of sponges. Aquaculture method is also one of efforts to anticipate and avoid the over-harvesting of sponges in nature. However, culture methods need to be determined to provide the platform for commercial success. In this study sponges (Callyspongia sp., Callyspongia basilana, and Haliclona sp.) were successfully cultured by transplantation method using polyethylene net with the initial explant sizes of 1 cm, 3 cm, and 5 cm. The result showed that the sponge growth and survival rates were dependent on the species. Callyspongia sp. and Callyspongia basilana gave the highest growth and survival rates on the treatment 3 cm with the final explants length reached 12.20 ± 2.35 cm and 7.603 ± 0.93 cm and survival rates reached 98.33% and 36.67%. In contrast, Haliclona sp. had the highest growth (21.67 ± 0.25) and survival (95%) on treatment 5 cm. Nevertheless, among the three species, treatment using 3 cm and 5 cm of initial explant sizes did not show a significant difference. Therefore for the efficiency of explants use, the best initial explant length for culturing the three species of sponges is 3 cm.

IN VITRO ANTAGONISTIC ACTIVITIES OF INDONESIAN MARINE SPONGE AAPTOS AAPTOS AND CALLYSPONGIA PSEUDORETICULATA EXTRACTS AND THEIR TOXICITY AGAINST Vibrio spp. Rosmiati Rosmiati; Habsah Mohamad; Tengku Sifzizul Tengku Muhammad; Najiah Musa; Aziz Ahmad; Noraznawati Ismail; Farida Mohamad; Nurhidayah Nurhidayah

Vibriosis is one of diseases which often results in mass mortality of Penaeus monodon larval rearing systems. It attacks shrimp of all stages in zoea, mysis and shrimp postlarva stage. This disease is caused by Vibrio spp, particularly Vibrio harveyi (a luminescent bacterium). Several kinds of antibiotics and chemical material have been used to overcome the disease but they have side effects to environment and human. The searching of bioactive compounds as an alternative treatment has been done for multi purposes. In this study diethyl eter, butanol and aqueous extract of Indonesian sponges Aaptos aaptos and Callyspongia pseudoreticulata were tested for in vitro activity against Vibrio spp. and Vibrio harveyi by using disc diffusion method. The result showed that all extracts of Aaptos aaptos gave a positive antibacterial activity towards those pathogenic bacteria. Meanwhile, only butanol extract of Callyspongia pseudoreticulata obtained to exhibit an antibacterial activity on those pathogenic bacteria. The strong anti-vibrio activity were shown by butanol and aqueous extract of Aaptos aaptos with the minimum inhibitory concentration (MIC) value of 0.313 and 0.625 mg/mL, respectively. Whilst, the butanol extract of Callyspongia pseudoreticulata indicated a low antibacterial activity with the MIC value of 10 mg/mL. Toxicity of those active extracts was evaluated by Brine Shrimp Lethality Test (BST). Interestingly, butanol and aqueous extracts of Aaptos aaptos did not show any toxic effect in Artemia salina larvae up to 8 x MIC (2.504 mg/mL and 5.000 mg/mL). It is the first report for the anti-vibr io activity of both Aaptos aaptos and Callyspongia pseudoreticulata. This results suggest that Aaptos aaptos has a potential to be used as a source of alternative compound to vibriosis prevention for mariculture.

Two different colors (green and brown) of Kappaphycus alvarezii have been farmed in Indonesian waters for many years. This study aimed at comparing two ‘varieties’, i.e. green and brown, both genetically and morphologically. Samples for DNA analysis were collected from a farmer in Pinrang Regency, South Sulawesi. Five universal primers i.e. Ca-01, Ca-02, P-40, P-50, and DALRP were selected to obtain DNA genetic markers in differentiating the green and brown varieties. To compare coloration patterns during cultivation and the growth performance of both varieties, a field experiment was performed in a seaweed farming area in Pinrang Regency, during dry season of August-September 2004. The result of genetic assessment showed that the five selected primers revealed different RAPD banding pattern for both varieties. P-50 and DALRP primers demonstrated the greatest amplification in differentiating RAPD fragment between green and brown varieties. Fragment 900 bp and 1.300 bp were consistently generated in the green variety but were not amplified in the brown variety. The result of the field study confirmed that the coloration pattern of green and brown varieties was fixed; no interchange in color occurred during one crop cultivation.
