Publisher : Aquaculture Department, University of Mataram

The production of vannamei shrimp (Litopenaeus vannamei) continues to decline due to parasitic attacks on ponds in North Gorontalo Regency. Ectoparasites are one of the factors that can cause failure in the cultivation of vannamei shrimp (Litopenaeus vannamei). This study aims to determine the type of ectoparasites, intensity, and prevalence of vannamei shrimp cultured in traditional ponds in the North Gorontalo Regency. A sampling of the research was carried out at five research stations. This research was selected randomly in 5 plots of ponds, and the total number of shrimp was as many as 150 tails. At each station, samples were taken of 30 vannamei shrimp (Litopenaeus vannamei). Sampling using fishing gear in the form of nets. The observed models were 8-10 cm in size alive. Observations of ectoparasites were carried out microscopically using a Zeis Binocular microscope with 10x magnification. Data analysis used descriptive analysis of ectoparasites, intensity, and prevalence of ectoparasites found. The study's results found four types of ectoparasites found in vannamei shrimp: Zoothanium sp, Epistylis sp, Carchesium sp, and Vorticella sp. The intensity of ectoparasite attack on shrimp was categorized as low to moderate infection, namely 4-7 individuals/head. The prevalence rate is 80-100%, with moderate to very severe disease.

Research on the benefits of Bacillus sp. in aquaculture has been done a lot. Currently, the aquaculture industry, especially shrimp farming, is facing AHPND disease, which is known to be caused by Vibrio parahaemolyticus. This study aims to see the effect of Bacillus sp. against virulence of V. parahaemolyticus in vitro using caseinase production as an indicator and survival of Artemia franciscana cultured axenically when challenged with V. parahaemolyticus. In in vitro tests, cultures of V. parahaemolyticus were grown with and without the addition of Bacillus sp. on Luria Bertani (LB) liquid media, and then the caseinase test was carried out using skim milk (SM) agar as a growth medium. In the challenge test, 10 axenic cultured Artemia sp. were distributed in falcon tubes containing 10 ml of sterile seawater. Challenge test treatments consisted of treatment A as control of Artemia culture without the addition of bacteria, treatment B Artemia culture adding by 106 CFU/ml V. parahaemolyticus, treatment C Artemia culture with the addition of 106 CFU/ml Bacillus sp., and treatment D Artemia culture with the addition of 106 CFU/ml V. parahaemolyticus and 106 CFU/ml Bacillus sp. All treatments were done in triplicates. The results showed that the addition of Bacillus sp. was able to reduce the caseinase production of V. parahemolyticus up to 29% indicated by the decrease of the clearing zone diameter formed on SM agar. Furthermore, the addition of Bacillus sp. in treatment D was able to significantly increasing (P<0.05) of Artemia's survival when challenged with V. parahamolyticus. This indicates that Bacillus sp. has a potential as a probiotic candidate to prevent disease caused by V. parahaemolyticus.

The main problem in cultivation is a disease that causes less optimal growth and even death. This study aims to analyze the effectiveness of black cumin extract on the inhibition of A. hydrophila bacteria, analyze its active ingredients, analyze its toxicity level to Tilapia, and analyze the effect of the extract on the survival rate and morphology of Tilapia after being infected with A. hydrophila bacteria. The method used was a completely randomized design (CRD) which consisted of 3 stages. Inhibition zone with 5 treatments 2 repetitions, namely P0 (aquades), P1 (25%), P2 (50%), P3 (75%), and P4 (100%). LC50 with 4 treatments 2 replications using regression analysis with the help of the probit table. In Vivo with 6 treatments, 3 replicates, namely P0 (NaCl injection) as a control-, P1 (bacterial injection) as control+, P2 (250 ppm), P3 (500 ppm), P4 (750 ppm), P5 (1000 ppm). The results showed that black cumin seed extract with various concentrations affected the inhibition of A. hydrophila, SR, and Tilapia morphology after infection with bacteria. The test of inhibition with concentrations of 25%, 50%, 75%, and 100% can inhibit the growth of bacteria A. hydrophila because it contains antibacterial activity compounds. The extract has toxic properties to Tilapia (LC50=220.23 ppm). Soaking fish for 30 minutes in the I n Vivo test P3 treatment is the best treatment because it can provide a high SR of 73.3 %. However, at high concentrations, it can reduce fish survival.

Aeromonas hydrophila is a bacterium that causes MAS disease (Motile Aeromonas Septicemia), often found by cultivators. This study aimed to determine the effectiveness of onion extract (Allium cepa L.) in replacing chemical antibiotics and the correct dosage to inhibit the growth of Aeromonas hydrophila bacteria in vitro. The research method used was a Completely Randomized Design (CRD) with 7 treatments and 3 replications, P1 (Control-), P2 (Control+), P3 (10% onion extract), P4 (25% onion extract), P5 (50% onion extract), P6 (75% onion extract), P7 (100% onion extract). The results showed that 30 ml of onion extract obtained from 101.3 grams of onion powder had a yield value of 29.812%. Some secondary metabolite compounds in onion extract are flavonoids, alkaloids, saponins, tannins, steroids, and phenols, which function as antibacterial compounds. The diameter of the clear zone of 10% onion extract has a value of 26 mm and has a value that is not significantly different from the use of 50% chloramphenicol antibiotics with an inhibition zone diameter of 26.67 mm, treatment with onion extract with a concentration of 100% gives the same inhibition zone diameter. The highest is 34.17 mm.

THE EFFECT OF IMMUNOSTIMULANTS FROM NATURAL INGREDIENTS ON VANAMEI SHRIMP (LITOPENAEUS VANNAMEI) IN INCREASING NON-SPECIFIC IMMUNITY TO FIGHT DISEASE Nuri Muahiddah; Rangga Idris Affandi; Wastu Ayu Diamahesa

Vanamei shrimp Litopeneus vannamei is a commodity with high economic value. Shrimp is Indonesia's main export commodity. The high value of sales and production of vanamei shrimp is constrained by the many disease attacks in the vanamei shrimp farming industry. An alternative solution that has been continuously researched for several years to combat shrimp disease is using immunostimulants from natural ingredients. Using natural ingredients for immunostimulants can increase the non-specific immunity of vanamei shrimp to ward off disease and be environmentally friendly. Immunostimulants can be administered orally, by immersion, or by injection. Immunostimulants from natural ingredients such as spirulina platensis, polysaccharides from seaweed such as carrageenan, sodium alginate, and fucoidan, extracts from red seaweed, as well as the use of polysaccharides from the bacterium Nodulisporium sp. KT29, Trichoderma sp. able to increase the non-specific immune system in L. vannamei shrimp. These immunostimulants increase non-specific immunity, such as total hemocyte count, phagocytosis activity, phenoloxidase, phagocytic, respiratory burst, superoxide dismutase, and total plasma protein. Immunostimulants from these natural ingredients can also fight infectious disease attacks.

Pearl oysters are a marine aquaculture commodity with high economic value. However, there are still many obstacles in pearl oyster cultivation activities, such as the need for quality seeds. This study aims to determine the effect of immersing pearl seeds in natural feed tanks of Chaetocheros sp. with different immersion periods on the growth and survival rate of pearl oyster (Pinctada maxima) seeds. The method used in this study is an experimental method using a completely randomized design (CRD), with 5 treatments and 3 replications, namely A (control/without immersion), B (0.5 hours), C (1 hour), D (1, 5 Hours) and E (2 Hours). The results showed that soaking the seeds in natural feed tanks had a significant effect on the growth of the shell (dorsal-ventral) of the pearl oyster Pinctada maxima (p<0.05). The highest growth was achieved in the 2-hour immersion period with an absolute growth value of 1.67 mm, a relative growth of 68.49% from the initial size, and a daily specific growth rate of 3.31% per day. This method must be tested on larger pearl oyster seeds and using other natural feed species and various natural mixes (multi-species).

POTENTIAL USE OF BROWN ALGAE AS AN IMMUNOSTIMULANT MATERIAL IN THE AQUACULTURE FIELD TO INCREASE NON-SPECIFIC IMMUNITY AND FIGHT DISEASE Nuri Muahiddah; Wastu Ayu Diamahesa
Journal of Fish Health Vol. 2 No. 2 (2022): Journal of Fish Health
Publisher : Aquaculture Department, University of Mataram

The aquaculture field continues to grow from year to year. This is because aquaculture fulfills the world's food needs. Aquaculture intensification continues. As a result of this intensification, the aquaculture environment experienced a decrease in water quality. This led to the rapid growth of bacteria, fungi, parasites, and viruses, resulting in a high incidence of disease outbreaks. An alternative solution that has been extensively researched recently is using immunostimulants to increase the non-specific immunity of fish and shrimp, which will help fish and insects prevent disease outbreaks. One of the natural ingredients that have the potential to become an immunostimulant is from the brown algae group. Immunostimulants from brown algae such as Hot-water Extract of Tropical Brown Seaweed, Sargassum cristaefolium, Sargassum glaucescens, Sargassum duplicatum, Sargassum wightii, Sargassum sp. Polysaccharides from seaweed, such as fucoidan extracts from brown algae, can enhance the non-specific immune system in shrimp Litopenaneus vannamei, Penaeus monodon, Fenneropenaeus indicus, and tilapia Oreochromis niloticus. These immunostimulants increase non-specific immunity, such as total hemocyte count, phagocytosis activity, phenoloxidase, phagocytic, respiratory burst, superoxide dismutase, and total plasma protein. Immunostimulants from brown algae can also fight bacterial disease attacks Vibrio parahaemolyticus, Streptococciasis, Streptococcus iniae, and White spot syndrome virus (WSSV) by increasing survival rate and can increase the growth and feed efficiency of cultivated commodities that are not given immunostimulants.
