Length - Weight relationship and condition factor of Phycis phycis (Linnaeus, 1766) and Phycis blennoides (Brünnich, 1768) [Actinopterygii, Gadiform, Phycidae] in the Gulf of Tunis

In our study length-weight relationship are presented for 213 Phycis phycis and 270 Phycis blennoides caught between September 2007 and August 2008 and collected from trawler fishing in the Gulf of Tunis. The length- weight relationships and the condition factor were computed separately for sexes and for different seasons. The parameters of the length-weight relationship for the population as a whole are all well correlated (r 2 > 0.92, p <
