Abstract

The objective of this research was to know the effectiveness of polyvalen  Vibrio vaccine to control vibriosis in humpback grouper (Cromileptes altivelis). The effectiveness of vaccine was evaluated by the survival rate (SR), relative percent survival (RPS), mean time to death (MTD) as well as growth rate of vaccinated fish. This research consisted of 4 treatments (control, injection, immersion, and oral vaccinations) in quadruplicates. Injection  vaccination was conducted by intraperitoneal injection of polyvalen vaccine at 107 cells/fish. Immersion vaccination was done by immersing the fishes at 107 cells/ml for 30 minutes. Oral administration of vaccine was also carried out  at 107 cells/fish. One week after the first vaccination, second vaccination (booster) was carried out at the same dosage and by the same administration. One week after the second vaccination, fishes were challenged with 3.16x104 cells/fish of Vibrio ordalii 3J by intraperitoneal injection, and reared for 20 days post infection. Results indicated that polyvalen Vibrio vaccine increased SR (P<0.01) up to 100%. Vaccination was also able to delay MTD of fishes. However, the vaccination was not influence the growth rate of fish.

Abstract

Different media condition, with salinity above the hatching threshold of cysts (100 ppt) and feeding with water flow as the main menu and Spirulina maxima flour as an additional feed encouraged the adult female Artemia salina to be oviparous and produce different amount of cysts depending on the treatments. The average amount of cysts produced by oviparous female Artemia salina during 77 day rearing was 22,719-78,616 cysts each female Artemia salina produced 18-13 cysts. Statistical analysis showed that all treatments did not reduce any significant effects on the production of cysts (p>0.05)

Abstract

The purpose of the research were to determine the toxicity and antimicrobial activity of ethanolic extract of sponges collected from Tabuhan Island, Banyuwangi and Menjangan Island, West Bali. Extracts were made by maceration of the sponge samples for 3 x 24 hours. The toxicity test was carried out by Brine Shrimp Lethality Test (BST) with 48 hours-old Artemia sp. The effect of ethanolic extract was identified by determining the mortality of Artemia sp. and LC50 of each extract was analyzed by using probit analysis. Antimicrobial activity was tested by agar diffusion method. The result showed that several ethanolic extracts exhibited toxicity to Artemia sp. The toxicity test showed that extract of sponge code B43 was the most toxic with the LC50 of 8.4 µg/ml. Antimicrobial activity test exhibited that ethanolic extract of sponge with code numbers B2, B57, B61 dan W5 were active against Candida ablicans, while the axtracts of sponge with code numbers B9, B35, B47, B51 (Liosina sp.), B57, B61, B63 and W11 were active against Staphylococcus aureus. One ethanolic extract from sponge with code number B57 exibited activity against Eschericia coli.

Abstract

The aim of this research was to identify the morphological and genetical variability in four strains of common carp (Cyprinus carpio) i.e. Majalaya, Rajadanu, Wildan and Sutisna. The study was conducted by analysis of truss morphometric and electrophoresis. Principal Component Analysis (PCA) was conducted to explore the patterns of body shape variability and the grouping among strains. The Degree of polymorphism, heterozigosity and genetic distance were used to identify the structure of populations. The results showed that the truss morphometric on head and caudal peduncle were the most contribute cells to distinguish the variability among strains. Based on genetic parameters analysis, strain of Rajadanu, Sutisna and Wildan were originaly coming from one strain with genetic distance about 0.0018 to Majalaya strain. Body shape similarity of Wildan and Majalaya strains was more influenced by their environment.

Abstract

Polymerase chain reaction (PCR) is a method that amplifies DNA which have been widely used in molecular biology technique. Based on the PCR, many methods have been developed on isothermal condition and the useful one is loop-mediated isothermal amplification of DNA (LAMP). LAMP reaction employs a Bst DNA polymerase and a set of four specific primers that recognizes a total of six distinct sequences of the target DNA and produces amount of different size of DNA. Many advantages have been achieved in LAMP such as the simple equipment for reaction and observation, short time, highly specific and sensitive procedure. LAMP has been used as a tools for detection many pathogens for human, animals and plants. Some fish pathogens as parasites, bacteria and viruses have been detected by LAMP. The principles and application of LAMP method are discussed in this paper.
