Performance of juvenile vaname shrimp (Litopenaeus vannamei) hemocyte cells number and differentiation in different cultivation technologies

Abstract

The Performance from The Number and Differentiation of Haemocyte Cell of udang vaname (Litopenaeus vannamaei) . Juvenile on Reared with Different Aquaculture Technology. This study aims to assess the performance of the number of hemocytes and cell differentiation of juvenile Udang vannamei (Litopenaeus vannamei) on reared with different levels of technology. The research was conducted by sampling directly to the location of intensive pond and traditional pond. The sampling frequency is 2 times at intervals of 15 days during the juvenile Litopenaeus vannamaei ± 2 months old. Hemolimfe parameters measured were the number of hemocytes, whereas the percentage of hemocytes differentiation by type of cell. The results showed that an increase in the number of juvenile litopenaeus vannamaei hemocytes on monitoring at 16:30, respectively rose from 30×106 cells/ml in traditional pond, and 34.8×106 cells/ml in intensive pond. at 12:00 monitoring, became 68.7×106 cells/ml traditional pond and 64.8×106 cells/ml in intensive pond. Furthermore, cell hyalin is higher percentage (54-61%) on traditional pond than globular cells (33-35%) and cell semiglobular (7-14%), but in intensive pond, globular cells is higher between hyaline cells and globular cells at each monitoring for 24 hours. This fact shows that the condition of vitality juvenile litopenaeus vannamaei reared on traditional pond more vibrant than litopenaeus vannamaei juveniles reared in intensive pond allegedly prone to stress, especially at dawn (4:30 a.m).
