Vaname shrimp (Litopenaeus vannamei) is one of the main aquaculture commodities in Indonesia because it has high economic value. But in the aquaculture it is known that there are diseases that cause death in shrimp before harvest time. Vibriosis is a disease caused by the Vibrio parahaemolyticus, bacteria which often attacks shrimp culture. Population control of Vibrio sp. done by giving immunostimulants and vaccines, as well as giving feed plus antibiotics. However, continuous use of antibiotics and improper doses will cause bacteria to become resistant and cause residues in the tissues. This study aims to examine the effect of Avicennia sp. fruit extract in preventing the infection of Vibrio parahae-molyticus in vaname shrimp on a laboratory scale. This study used the experimental method Complete Random Design (CRD), which consisted of five treatments with different concentrations of Avi-cennia sp. fruit extracts and three replications of individuals in the population. The results showed that Avicenniasp. fruit extract Avicennia sp. able to influence the inhibition of the growth of Vibrio parahaemolitycus bacteria and prevent the occurrence of vibriosis disease . This can be seen by the value of Relative Percent Survival (RPS) which is limitited to 50%, can slow down the time of death of the shrimp seen from the Mean Time to Death (MTD), and followed by a high Survival Rate (SR). The concentration that most affected the treatment was the concentration of 350 mg/l.Keywords: Avicennia sp extract, vaname shrimp, Vibrio parahaemolyticus

Abstrak The research was conducted in November 2018 - February 2019 in the Sub-watershed of the Lahombuti River in Lahotutu Village, Konawe Regency. The purpose of this study was to determine aspects of population density and distribution patterns of the Kalambodo (A. woodiana) in the Sub watershed of the Lahombuti tributary in Lahotutu Village, Wonggeduku District, Konawe Regency. The sampling location was determined using the purposive random sampling method. Sampling of Kalambodo (A. woodiana) was carried out at the location with the greatest abundance of A. woodiana, in the Sub watershed of the Lahombuti tributary of Lahotutu Village, on the "Main Rice Field Irrigation Channel" (diameter: ± 1,75 m, length: ± 4500 m, depth: ± 110 cm). Sampling of A. Woodiana was carried out at the same station with different spot sampling points. The Kalambodo samples were taken using a 1x1 m2 sized transect on 3 randomly assigned plots. The range of A. woodiana density per sub station is November 2018 amounting to 67-95 ind/m2, December 2018 is 41-61 ind/m2, January 2019 is 41-148 ind/m2 and February 2019 is 101- 114 ind/m2. The average density based on the period from the highest to the lowest is obtained in February 2019, January 2019, November 2018, and December 2018, which is 106.67 ind/m2, 81.33 ind/m2, 78 ind/m2, and 53 ind/m2, respectively. The distribution pattern of A. woodiana in the Sub-watershed of the Lahombuti River Basin generally shows a uniform category (Id <1), with a range of morisitha index values of 0.65-0.87.

Abstrak Indonesia is an ideal place for coral growth because of the tropical climate. Rakata Island is included in the Krakatau Islands Nature Reserve and Marine Reserve area which is influenced by the volcanic activity of son of Krakatau Archipelago and human activities. Both of these activities will affect the growth of coral reefs. The purpose of this study was to determine the current condition of coral reefs and the diversity of living coral forms on Rakata Island. Collecting data for analysis of coral reef cover using the Line Intercept Transect (LIT) method was parallel to the coastline of Rakata Island at two points. The percentage of live coral cover from points I and II at a depth of 5 meters was 50.69% and 33.80% classified as in good and moderate conditions respectively. While the percentage of live coral cover at a depth of 10 meters at points I and II were 41.90 % and 16.01% whice were in moderate and poor conditions. The coral reefs mostly found in point I were leaf corals (CF) namely Turbinaria reniformis and Turbinaria frondens, while in point II were massive corals (CM) were found i.e. Goniastrea edwardsi, Favia pallida, Montastrea valenciennesi, Favites abdita, Astreopora listeria, and Favites complanata.

Abstrak Goldfish (Carassius auratus) is one of the fishes that can be infected by parasites. Commonly, this fish is often attacked by Argulus japonicus ectoparasites. Control of infestation in A. japonicus can be done by utilizing one of the natural ingredients, Moringa oleifera leaf extract, which contains of alkaloids, tannins, saponins and flavonoids. This study aims to determine the effect of M. oleifera leaf extract in reducing the infestation of A. japonicus and the optimal concentration of M. oleifera leaf extract in reducing the infestation of A. japonicus in goldfish (C. auratus). This study used a completely randomized design (CRD) with treatments namely control, 600 ppm, 700 ppm, 800 ppm and 900 ppm with four times of replication. The main parameter is the percentage decrease in infestation of A. japonicus. The results of the research data were analyzed by using ANOVA and followed with the Ducan Multiple Range Test. The results showed that Moringa leaf extract could reduce the infestation of A. japonicus. The optimal concentration of Moringa leaf extract in reducing the infestation of A. japonicus was obtained from a concentration of 700 ppm.

Indonesia is one of the countries with the highest potential and production of vannamei shrimp (Litopenaues vannamei) in the world. Therefore, the government continues to improve theactivity of vannamei shrimp farming continuously. This study aimed to determine whether the water quality of the waters in Larangan Glintong Village, Bangkalan-Madura, East Java was suitable for vannamei shrimp farming activities. Water quality was one of the keys for successful vannamei shrimp farming since it could affect the metabolism, reproduction, osmoregulation and stress of the organism. The parameter water quality used in this study was salinity, temperature, and pH. This research was a water quality survey that was carried out for three months (March-May). The result showed that the average water salinity was 30.5 ppt. The average DO and brightness showed 7.02 mg/l and 30.69 cm. The average temperature at there was 29.41oC while the pH valued showed 8.13. The It could be concluded from water quality aspect that pond in Larangan Glintong Village, Bangkalan-Madura could be used for vannamei aquaculture development.
