Abstract:
A study of 249 individuals of Pterois miles migratory species from the Red Sea to the eastern Mediterranean Sea, which invaded the Syrian coast and spread in it in large amount, established and adapted to the new environment, these fish were caught from the Syrian marine waters during a whole year (2019-2020). The type of toxic complex was determined and it was found that Tetrodotoxin is one of the strongest and most dangerous marine toxins, and it causes severe pain, neural effects and serious symptoms that may lead to death. The percentage of the toxic complex were determined in the muscles and fin spines, and the fat covering the internal organs. It was found that the highest percentage of the toxic complex was in the fat surrounding the internal organs with a rate of 21.88%, then muscles came in second place with 6.31%, and spins took the third and last place with a rate of 3.63%. As for the percentage of the toxic complex according to sex, it was higher in females (13.26% for fat, 3.82% for muscles, 2.74% for spines) than males (12.69% for fat, 3.60% for muscles, 1.28% for spines), in addition to that the percentage of the toxic complex during The wet season (29.34% for fat, 5.95% for muscle, 4.50% for spines) is higher than during the dry season(15.48% for fat, 6.63% for muscle, 2.88% for spines).
Keywords: Lionfish, Pterois miles, percentage of toxic complex, Syrian coast.
