Abstract
Seventy five of blue tilapia fish which range of total length between 125 to 330 mm and weight between 30.6 to 1230 g from the Euphrates River at the Hindia Barrier. A number of physical and chemical properties were recorded and found suitable for living and fish growth . However the annual increases in the total lengths were oscillatory and not subject to the Lee̕s phenomenon . The highest increase in the total length recorded in the first year of fish life in percentage of 27%, This fish lived up to the eighth years of age and their numbers are decreasing with increasing of age. The relationship between the total length and weight was not identical (allometric)with value of regression (b) 3.21, Growth parameters for k and to values k (yr) equal to -0.31 and to equal to 0.85 (yr)-1. Expected length infinity L∞ is 358 mm, the condition factors of 3.5 and the sex ratio was 1.1: 1 in males. In conclusion, the blue tilapia fish reachs to the eighth-old while less numbers recorded in the older age groups, and the annual increases in length irregular.
