Title: Population structure of the bluespotted cornetfish Fistularia commersonii (Osteichthyes: Fistulariidae) in the eastern Mediterranean Sea
Abstract: The bluespotted cornetfish, Fistularia commersonii, has established in a few years a large population in the Mediterranean Sea and is considered among the most spectacular Lessepsian fish invaders. This work estimated the essential population structure of the species in the eastern Mediterranean off the coast of Lebanon. A total of 1073 individuals were sampled between 2005 and 2009. Fish size ranged from 19.2 to 113.1 cm L T and the most frequent size class was 55 cm L T . Weight-length relationship was described by the equation W G = 1.066 × 10 –4 L T 3.4063 , showing a positive allometric growth; the overall sex ratio did not deviate significantly from 1:1 throughout the sampling period. The size range and number of individuals examined in this study could be considered representative of the population living in the eastern Mediterranean and provides basic data that can be used in specific studies that aim to understand the biology and ecology of this invasive fish in the new environment.
