Age, growth parameters and food composition of Invasive Red Lionfish (Pterois volitans L., 1758) in İskenderun Bay
Age, growth parameters and food of Pterois volitans (Linnaeus, 1758) Red lionfish were studied. A total of 254 lion fishes (P. volitans and Pterois miles) were collected from commercial drift net, angling fisheries and diving with hand net southern coast of the Iskenderun Bay between March 2018 and...
