Abstract

Morphological characteristics, stomach content and toxicity properties of puffer fish were studied. A sample of 28 individuals of Tetraodon nigroviridis and 21 individuals of Xenopterus naritus were collected from three sampling sites in Sarawak waters using three layered net. These two puffer fish species showed the difference in their morphological characteristic (e.g., skin colour). Analysis showed that morphometric measurement of T. nigroviridis collected from Rambungan River and Sampadi Island (BW: 47.04±11.60 g; TL: 11.1±1.2 cm; SL: 8.0±0.7 cm; HL: 3.4± 1.3 cm) and (BW: 93.32±35.14 g; TL: 13.7±1.6 cm; SL: 10.5±1.2 cm; HL: 4.0±0.4 cm) respectively were different in their range of size. Analysis also showed the difference in the range of size of X. naritus (BW: 335.00 ±35.36 g; TL: 23.3 ±2.8 cm; SL: 18.7 ±1.8 cm; HL: 4.8 ± 0.4 cm), (BW: 317.78±102.82 g: TL: 18.3 ±2.1cm; SL: 18.3 ±1.8 cm; HL: 5.5 ±0.7 cm) and (BW:278.00 g; TL: 20.1 cm; SL: 16.3 cm; HL: 4.1 cm) collected from Rambungan River, Sampadi Island and coastal area of Lundu respectively. Meristic count analysis of T. nigroviridis and X. naritus (AR: 11-14; FR: 8-1I; DR: 13-15; PR: 20-23) and (AR: 24-28; FR: 10-12; DR: 30-35; PR: 16-18) respectively showed the difference in the range of the rays counted. Stomach content analysis showed that T. nigroviridis was carnivorous fish and X. naritus was omnivorous fish. The concentration of TTX detected in liver of X. naritus was 39.39µg/g by using HPLC.
