| Abstract | ||
| From February 2007 to January 2008, monthly samples of shank (Acanthopagrus latus) were taken from three stations at Al-Razzazah lake,by using a range of gill nets and seine nets. A total of 318 fish were taken from all stations. The age data determined from the scales showed that there were eight age classes present in station 1 and 2 and seven age classes in station 3. The increment in length of A. latus at the area of study showed a tendency to decrease with the increase in age after the fourth year of life. The length- weight relationships of both sexes specimens are expressed by the following equations:Log = -1.93 + 2.67 Log ….. for station (1) fishLog = -2.08 + 2.74 Log …. For station (2) fishLog = -2.02 + 2.39 Log …. For station (3) fish It seems from the above equations that the growth of A. latus in the area of study is allometric. | ||
