| Abstract: |
| In 1982-1985, 689 specimens of red grouper, Epinephelus akaara (Temminck et Schlegel) were collected from the coast of Haifeng and Lufeng Counties, Guangdong Province for the investigation of its growth by means of scale method. The results thus obtained are as follows: 1. Relationship between scale length and body length is: L = 43.5117 +107.8589S2. Relationship between body length and body weight is: W = 3.04×10-5L2.97103. The growth rate of this fish up to 5-year-old was computed by using back-calculating method. 4. General growth pattern of E. akaara was studied by using on Bertalanffy growth equation, parameters thus obtained were: L∞ = 503.67mm; W∞=3243.02g; K = 0.2663; t0=-0.3198 years, knee of growth in body weight laid in 3.85 years. |
