Abstract

Aeromonas salmonicida are specific bacteria that can cause infections and death to the cultivation of carp (Cyprinus carpio) during larval stage. Death in carp can be prevented by a vaccine, but the vaccine can only be given on the seed over the age of 3 weeks. Maternal vaccination needs to be done to improve the immune system of the larvae by means of inactivated whole cell vaccine A. salmonicida on broodstock ready to spawn. Aims to determine the effectiveness of vaccines on breeders carp to the parent antibody titer test and larvae, as well Survival Rate (SR) and the Relative Percent Survival (RPS) larvae. This research was conducted with a completely randomized design, 4 treatments A (control); B (0.3 ml/kg); C (0.4 ml/kg); D (0.5 ml/kg) and 3 repetitions. The results show that the antibody titer of 0.3 ml dose capable of providing agglutination reaction to pitting 7th (64x dilution) in broodstock, and vaccine doses 0,4ml on broodstock able to give agglutination reaction to the larvae until all 6 wells (32x dilution). A dose of 0.4 ml/kg resulted the highest SR and RPS with 96.11% and 81.25% respectively. Clinical symptoms of redness in control larvae was spread throughout the body whereas on the vaccine treatment was only in certain body parts.Keywords: A. salmonicida, vaccines, maternal immunity, larva, specific immune respon

Abstract

In vaname shrimp cultivation system, bacterial disease is a problem that often arises that mainly caused by the bacteria Vibrio sp. Sinbiotic application is one way to prevent disruption of the disease. Sinbiotic is nutritional supplements that made from the combination of probiotic and prebiotic that can provide beneficial effects to the host. This research uses a local sinbiotic of probiotic bacteria Bacillus sp. D2.2, which comes from the traditional ponds in the Mulyosari village, Pasir Sakti district, Lampung Timur Regency, Lampung. Prebiotic that used in this research made from meal extracts of purple sweet potato that had the best capability to support the growth of bacteria probiotic Bacillus sp. D2.2. This research aims to know the effectivity of sinbiotic against the infection of vibriosis againts to vaname shrimp by doing analysis of clinical symptoms and tissue damage post test challenge using bacteria Vibrio harveyi. The results showed that addition sinbiotic gave effect to SR 6,25 %, MTD 13,80 hour, and clinical symptoms and then tissue damage is lower than without the feeding of sinbiotik.

Abstract

Intertidal zone in reef flat is the extreme condition for many species of corals. Periodical tides, wave action and sedimentation become the main challenging factors which usually avoided by most of coral species. However, Montipora digitata is the species that found abundant in these conditions. Having relatively small and short-lived colony, forced this species to find the strategy to survive and maintain the energy efficiently. Understanding biology and life history of M. digitata in the coral reefs is the key to understanding how this species can adapt to the extreme conditions. The biology and life history of this study focused on the population size structure, reproduction, competitive interactions, investment repair and maintain and types of selection. M. digitata leaded to productivity as a strategy to cope with any extreme condition. This pattern relatively matched with r-and S-R selection.

Abstract

World crustacean aquaculture has developed considerably since the 1980’s and is now worth more than USD 10 billion per year. However, the economic growth of this industry has been severely affected by problems related to diseases and environmental degradation. Viral disease outbreaks are particularly concerning and have caused massive economic losses around the world. However, there is still no effective treatment for most viral diseases. Current research on crustacean diseases focuses on the role of innate immune system as the first defence mechanism against viral infections. Of the available antiviral immune responses, interferons (IFNs) are known to have ability interfering effect on viral replication, particularly in vertebrates. This paper reviews the function and molecules involved in the vertebrate interferon system and whether similar molecules and pathways may exist in crustacean immune systems. Therefore, IFN or IFN-like proteins in crustaceans may provide the key to managing viral diseases.

Abstract

Tiger Grouper is one of the sea water fish commodities that is quite popular with the community and has a high economic value. The problem faced by farmers is the attack of Vibriosis, one of which is caused by the Vibrio alginolyticus bacteria. The use of synthetic antibiotics has been widely used but has many adverse effects, so it needs new alternatives for the treatment of Vibriosis disease. One of them is by using the extract of lifelong leaf extract. Life-sustaining plants (Gynura procumbens) contain secondary metabolites such as flavonoids, tannins, and antibacterial saponins. This study aims to determine the best dosage of lifelong leaf extract for the treatment of Vibriosis disease in tiger grouper. The study was conducted in two stages, namely in vitro and in vivo. Before the fish were treated with feed that had been given a sambung deca leaf extract, the fish were challenged using Vibrio alginolyticus with a density of 108 CFU / mL as much as 0.1 mL / head and then fed with treatment and maintained for 21 days. The results of the in vitro study showed that the life of sambung leaf extract at a dose of 700 ppm had a broad inhibitory effect on V. alginolyticus, which amounted to 10.47 mm compared to other treatments. Whereas when continued for in vivo testing, a dose of 350 ppm in general has been applied for the treatment of attacks of Vibrio alginolyticus in tiger grouper.

Abstract

Pacific white shrimpculture is having problems caused by bacteria infection. The cause of  bacteria infection is V. harveyi, it can decrease seed production. Pathogenicity of vibriosis can decrease with inhibition by other types of  bacteria. The aim of the research was to get competitor V.harveyi isolates through identification and challenge test in vitro and in vivo. The result of screening of bacterial isolates were obtained from cultivation supplement products to produced 4 pure isolates with different morphologically colonies and cells. There was one potential isolate could inhibits V. harveyi by inhibition test in vitro. Biochemical test from three different  laboratories were identified that Acinetobacter sp. as competitor to V. harveyi and it was not pathogenic to Pacific white shrimp. Challenge test Acinetobactersp. against V. harveyi on Pacific white shrimp larvae was conducted through three treatments, without given V.harveyi and Acinetobacter sp. As controls; treatment with given bacteria V.harveyi and treatment with given V. harveyi and Acinetobacter sp. The challenge test results showed that treatment with given of V.harveyi and Acinetobacter sp. may decreased V. harveyi density of 6.3x106CFU/mL to 7.5x103CFU/mL which could suspected to decrease pathogenicity of competition number of colonies.
