The objective of this study was to evaluate the effectiveness of vaccination on tilapia seedlings resulted from the vaccinated parent by hyperosmotic infiltration method at four different salinity to prevent Streptococcus agalactiae bacterial infection. A total of 100 seeds aged 20 days from the vaccinated mother were immersed in four different salinity: 0 ppt (control), 10 ppt, 20 ppt, and 30 ppt for five minutes, then removed and transferred into vaccine-containing containers for 30 minutes. Further maintenance was performed in freshwater aquariums and at days 10, 20, and 30 post vaccination, the immune system performance: Relative Percent Survival (RPS) after the challenge test, specific antibody level, and lysozyme was observed. The study was conducted using a complete randomized design with three replications. The results showed that the 10 ppt salinity treatment gave the best results compared to the others and control. The final RPS (10 ppt) value was 84.72%, 66.49%, and 47.06%, on the 10th, 20th, and 30thh days of vaccination, respectively. Specific antibody levels (10 ppt) were 0.077, 0.078, and 0.077 and lysozyme 0.092, 0.084, and 0.032 at days 10, 20, and 30 post vaccination, respectively. The value of RPS and specific antibody level at 10 ppt salinity was significantly different (P <0.05) compared to the other treatments, while the lysozyme treatment activity of 10 ppt was not significantly different compared to the 20 ppt treatment. Vaccination using 10 ppt saline hyperosmotic infiltration can improve the performance of the immune system by improving maternal immune protection against Streptococcus agalactiae infection.

The objective of this work was to evaluate the performance of Pacific marine shrimp (Litopenaeus vannamei) and tilapia (Oreochromis niloticus), in a polyculture in tanks subjected to different stocking densities and feeding strategies, in comparison with monoculture. Two experiments were performed, at the same time, in a completely randomized design with three treatments and four replicates each. Treatments for experiment I were: monoculture with 10 shrimp per m² (10S:0T); polyculture with 10 shrimp and 0.5 tilapia per m² (10S:0.5T); and polyculture with 10 shrimp and 1 tilapia per m² (10S:1T). Shrimp was the main crop, and feed was provided based on shrimp biomass. Treatments for experiment II were: monoculture with 2 tilapia per m² (2T:0S); polyculture with 2 tilapia and 2.5 shrimp per m² (2T:2.5S); and polyculture with 2 tilapia and 5 shrimp per m² (2T:5S). Tilapia was the main crop, and feed was provided based on fish requirements. In the experiment I, tilapia introduction to shrimp culture resulted in lower shrimp growth and poor feed conversion rate. In experiment II, shrimp introduction to tilapia culture did not interfere with fish performance. Polyculture is more efficient with the combination of 2 tilapia and 2.5 or 5 shrimp per m² and feed based on fish requirements.

MAS disease (Motile Aeromonas Septicemia) is a disease caused by A. hydrophila bacteria that attack tilapia and other freshwater fish species. The use of antibotics and chemicals in the continuous prevention and treatment of this disease can damage the aquatic environment and can cause bacterial resistance to antibotics, so antibotic use becomes ineffective. The study used a Complete RandomIzed Design (RAL) with an experimental method consisting of 5 treatments and 3 repeats. Treatment in this study is (P1) without soaking garlic extract and without infected bacteria Aeromonas hydrophila, (P2) without soaking garlic extract and infected bacteria Aeromonas hydrophila, (P3) soaking garlic extract with a concentration of 1% and disinfection of bacteria Aeromonas hydrophila, (P4) immersion of garlic extract with a concentration of 1.5% and infected bacteria Aeromonas hydrophila, (P5) soaked garlic extract with a concentration of 2% and infected with Aeromonas hydrophila bacteria. The results showed that the SR value of tilapia fish in each treatment had values ranging from 0.0% to 66.7%. Relative percent survival (RPS) tilapia seeds in each treatment have values ranging from 0.0% to 66.7%. The conclusion of this study is that giving garlic extract with different concentrations has a real different influence on survival rates and relative percent survival (RPS).
