The results of the study of the effects of salinity, temperature, acidity, alkalinity and DO in the growth of crabs in Trang. It was found that the average salinity of the water in the Trang Urban forest was 6 ppt, Pak Meng beach was 32 ppt, the Kantang hot spring forest park areas was 6 ppt, the Thungmalam mangrove forest was 2 ppt, and the Nong Samet mangrove forest was 27 ppt. Pak Meng beach and Nong Samet mangrove forest are suitable for the growth of sea crabs. The study of water temperature. It was found that the average water temperature in Trang urban forest was 27.6 °C, Pak Meng beach was 28.6 °C, the Kantang hot spring forest park areas was 29.4 °C, the Thungmalam mangrove forest was 30.0 °C, and the Nong Samet mangrove forest was 30.9 °C. Thungmalam mangrove forest and Nong Samet mangrove forests have suitable water temperature for sea crab growth. The study on the acid-alkalinity. It was found that the average pH of water in Trang urban forest was 7.13, 7.82 in Pak Meng Beach, 7.78 in the Kantang hot spring forest, 8.46 in the Thungmalam mangrove forest and 8.42 in the Nong Samet mangrove forest. The Pak Meng beach, Kantang hot spring forest, Thungmalam mangrove forest ,and Nong Samet mangrove forest have suitable pH value for growth of sea crabs. The study on the dissolved oxygen. It was found that the average dissolved oxygen in Trang urban forests was 2.5 mg/L. The Pak Meng beach was 5.0 mg/L, Kantang hot spring forest was 1.0 mg/L, Thungmalam mangrove forest was 4.5 mg/L and Nong Samet mangrove forest was 2.0 mg/L. The Pak Meng beach and Thungmalam mangrove forest have suitable dissolved oxygen value for the growth of sea crabs.
