摘要

The biometric characteristics ofTrachinus araneus,Trachinus dracoandTrachinus radiatusfrom the Egyptian Mediterranean waters at the West of Alexandria City, were studied. In total, 105, 96 and 55 specimens of these three Fish species were sampled, respectively, by the use of bottom trawls operated in the sectors of El-Dabaa and Sidi Abd El Rahman. The morphological characteristic and related index ratio were determined. The results showed thatT. araneustotal length varied from 10.9 to 30.0?cm TL with mean length of 19.87?±?5.43?cm TL and a number of horizontal dots appear to be distributed along the lateral line,T. dracototal length was 11.8 to 27.6?cm TL with a mean length of 17.85?±?4.23?cm TL, and specimens of this Fish species showed yellow vertical oblique lines on the body. On the other hand,T. radiatusis characterized by a total length of 10.6 to 35.0?cm TL with a mean length 18.04?±?4.87?cm TL, and by circular brown dots spread on the whole body and head. Furthermore, these three Fish species have poisonous spines, one on each operculum, and both spines on the internal border of the dorsal part of each eye orbit. The morphometric regression of each morphometric character showed close agreement between the observed and calculated values.
