Abstract

Hepatopancreas study of Pacific White shrimp, Penaeus vannamei was done on the shrimp samples from a commercial shrimp farm in Setiu, Terengganu. About six individual shrimps were collected randomly from eight different shrimp grow-out ponds for histopathology analysis at Universiti Malaysia Terengganu laboratory. Most of the hepatopancreas samples appeared to be healthy, however in the histopathology results showed signs of unhealthy hepatopancreas conditions including slough hepatopancreas tubules cells (SHP), degeneration of Tubules Lumen (TL), enlarged of the hepatopancreas nuclei cell and lack of B, F and R epithelial cells in the hepatopancreas tubules.
