Description:
The aim of this study was to histopathology of the shrimps fed with G. corticata, S. cerevisiae compared with
the shrimps fed without yeast and alge in the face of white spot syndrome virus . 1200 healthy shrimp SPF L.
vannamei subadult with average weight of 10±1.02 g were collected and divided to three groups . The first group
(T1) fed with commercial pellet, second group (T2) fed S. cerevisiae (2 g/ Kg), third group (T3) fed G. corticata
powder was mixed with shrimp feed (2 g/Kg) and after 10 days injected with WSSV and all group maintained
for 25 days. For histopathology survey, the samples of gills, hepatopancreas,lymphoid tissue, stomach and gut
were fixed in davidson solution. Tissues were embedded in paraffin wax, sectioned at 5µm and stained with
hematoxylin-floxin eosin. Survival rate in T2 and T3 was higher and significantly different (P〈0.05) with T1,
whereas, T3 showed significantly different (P〈0.05) survival rate with T2 at the end of experiment. This study
showed that the shrimps fed with G. corticata and S. cerevisiae are effective immunostimulants in shrimp L.
vannamei and perform better the fed with commercial pelle in the face of White spot virus.
