Humoral and Haemocytic Responses ofLitopenaeus vannameito Cd Exposure

White shrimp,Litopenaeus vannamei, subadults were exposed to four dilutions of the 96 h cadmium LC50reported for postlarvae (PL12) of this species, and the effects were evaluated after 5, 48, and 96 h of exposure. While treatments did not affect survival and hemolymph clotting time increased with time, but not as a response to Cd exposure, the intensity of other responses was related to concentration, to time of exposure, and to their interaction. Hemocyanin decreased with time in all metal concentrations but increased in the control treatment, and an almost similar trend was observed with hemocyte numbers. As an initial response, phenoloxidase activity decreased with all metal concentrations, but it increased later to values similar or higher than the control treatment.

ABSTRACT The increasing demand of white shrimp Litopenaeus vannamei requires the application of intensive culture system. However, intensive culture system of white shrimp could increase the risk of disease outbreak. The application of sinbiotic may provide solution to the problem. This study was aimed to evaluate the effectiveness of the use of technical sinbiotic on the survival and growth of white shrimp in ponds. This study consisted of four treatments; treatment K (control), treatment A (probiotic 0.5% and prebiotic 1%), treatment B (probiotic 1% and prebiotic 2%), and treatment C (probiotic 2% and prebiotic 4%). The results showed that administration of sinbiotic had no significant differences on survival rate, growth rate, feed conversion ratio, size, and biomass of shrimp (P>0.05). However, based on analysis of business, sinbiotic A provided higher profits to the farmer (Rp10.230) compared to other symbiotic treatments and control. Keywords: Litopenaeus vannamei, sinbiotic, technical media ABSTRAK Permintaan terhadap udang vaname Litopenaeus vannamei yang semakin meningkat membuat sistem budidaya udang sebaiknya menggunakan sistem budidaya intensif. Namun demikian sistem intensif pada budidaya udang vaname dapat meningkatkan risiko timbulnya penyakit. Penggunaan sinbiotik diharapkan dapat memberikan solusi dalam mengatasi masalah tersebut. Penelitian ini bertujuan untuk menguji efektivitas penggunaan sinbiotik teknis terhadap sintasan, pertumbuhan, dan keuntungan usaha udang vaname yang dipelihara di tambak. Penelitian ini terdiri atas empat perlakuan, yaitu perlakuan K (kontrol), perlakuan A (probiotik 0,5% dan prebiotik 1%), perlakuan B (probiotik 1% dan prebiotik 2%), dan perlakuan C (probiotik 2% dan prebiotik 4%). Hasil penelitian menunjukkan bahwa pemberian sinbiotik tidak berbeda nyata dalam nilai sintasan, laju pertumbuhan, rasio konversi pakan, size, dan biomassa udang (P>0,05). Namun demikian, berdasarkan analisis usaha perlakuan A memberikan keuntungan lebih tinggi (Rp10.230) dibandingkan dengan perlakuan sinbiotik lainnya serta kontrol.

Bacterial Richness

Juvenile Litopenaeus vannamei (1.05 ± 0.1 g) were fed during 4-week with four experimental diets: control (Ctrl), inulin as prebiotic (5 g kg-1) (Pre), Bacillus subtilis and Lactobacillus sp. as probiotic (1 x 105 CFU g-1) (Pro), and a mix of inulin + B. subtilis and Lactobacillus sp. (5 g kg-1 + 1 x 105 CFU g-1) (Syn). Shrimps fed Syn diet showed significantly better feed utilization and higher growth than those in control diet (P < 0.05). The probiotic employed induced higher intestinal bacterial richness, whereas inulin in feed induced higher bacterial diversity in shrimp intestine. The most dominant bacterial phylum in the shrimp intestine among treatments was Proteobacteria with abundance ranging between 80 and 84 %. Prebiotic diet (Pre) increased relative abundance of Firmicutes in shrimp intestine (2 %) compared to the rest of the treatments (0.6 %). Nevertheless, when probiotics were included in the feed (Pro and Syn), a reduction between 3 and 13 % in the relative abundance of Vibrio sp. in shrimp intestine was observed respect to the control treatment, which represent an advantage to control potential pathogens of this genus.
