| Abstract | ||
| The aim of this work was to study the age and growth of Goldfish Carassius auratus L. in AL-Habbaniyah Lake. The relationship between total length (L) and weight (W) was expressed by the following equation: Log W=-5.46 + 3.27 Log L r = 0.98 (P≥0.05). The obtained results indicated that the growth of goldfish in Habbaniya lake was allometric.The relationship between total length (L) and scale radius (S) expressed by the following equation: L=30.70 + 29.47S, r = 0.829 (p≥0.05). Age of fish was determined by scales. The age data showed that there were six years classes for both males and females. The most rapid growth in length occurred during the first year of life, while the highest growth in weight occurred during the sixth year of life. Maximum expected length (L∞) was 266 mm and maximum weight (W∞) was 294 gm, that fish can attained. | ||
