A study on the ecology and fecundity of puffer fish, Xenopterus naritus, from the family of Tetraodontidae, was carried out in Batang Saribas, at five selected stations; Kampung Supa, Tanjung Keranji, Kampung Manggut, Tanjung Baring, and Kampung Serembang. Congregation of puffer fish is mainly due to spawning activities. Fish samples were analyzed with regard to the relationship between different indices of gonads and body size. Evidence of spawning includes the existence of eggs in ovaries in females and matured sperm in males. Gonadosomatic index for females (30.9 %) is relatively higher than male (5.24 %). The puffers are yellowish in colour, with significantly larger female compared to male puffers. Total length in males and females increased with increasing body weights. Fecundity is higher in females with larger volume of ovary. The average number of eggs is 8855 ± 3764. It was observed that puffers with heavier body weight contain either heavier gonads or heavier liver weights.
