PROFILE OF BLOOD OF SEABASS INFECTED BY Vibrio sp. WITH THE ADDITION OF ALOE VERA EXTRACT

Abstract

Seabass (Lates calcarifer Bloch) is a type of consumption fish that is quite popular in Indonesia. One of the obstacles faced in the cultivation of white snapper is the presence of disease. One of the diseases that attack seawater is Vibrio harveyi. Aloe vera contains several important therapeutic ingredients. The purpose of this study was to determine the effectiveness of the addition of aloe vera extract (Aloe vera) in feed to the addition of total red blood cells, white blood cells, hemoglobin levels, differential leukocytes and survival rate of white snapper and to determine the extra dose of aloe vera (Aloe vera) which the best. This study used a Completely Randomized Design (CRD) consisting of 6 treatments and 3 replications to obtain 18 experimental units. Treatment P0: 0 ml extract / 500 g feed, P1: 10 ml extract / 500 g feed, P2: 20 ml extract / 500 g feed, P3: 40 ml extract / 500 g feed, P4: 60 ml extract / 500 g feed , P5: 100 ml extract / 500 g feed. Data from observations of white blood cells, red blood cells, differential leukocytes and survival rates were tested using Analysis of Variance (ANOVA) and if significantly different continued with Tukey's test at 5% significance level. The results showed that all treatments had a non-significant effect (p <0.05) on the number of erythrocytes, hemoglobin levels, leukocytes, lymphocyte cells, neutrophil cells, but had a significantly different effect on the number of leukocytes, the number of monocytes and the level of survival of seabass
