Abstract

Puffer fish from Tetraodontidae family is the common puffer fish to possess tetrodotoxin (TTX) which can cause puffer fish poisoning and effect human health. In this study, a total of 15 yellow puffer fish or Xenopterus naritus (9 males, 6 females) purchased from Asajaya, Sarawak were analysed for the content of Tetrodotoxin (TTX) in different tissues (stomach, liver, testis, gonad) by using the Thin Layer Chromatography (TLC) screening method. The morphological measurements were measured by standard measuring using DAN electronic balance and Wildco Fish measuring board. The mean of body weight, total length and standard length of the males (n=9) were ranges from 52 - 94 g, 11.6 - 21.7 cm and 10.7 - 14.5 cm respectively. While, the female (n=6) were ranges from 76.8 - 424 g, 16.7 - 26.5 cm and 14.2- 23.0 cm respectively. Results show that all the tissues in this study contain TTX that range between 0.71 and 0.50 in TLC analysis. The highest Rf value recorded for TLC analysis was in gonad (0.80 ± 0.13). The information in this study indicates the importance of the proper removal of the toxin tissues to guarantee safe consumption of puffer fish.
