Growth characteristics of intensively cultured Scophthalmus maximus

A study has been carried out on growth characters of industrially farmed turbot, Scophthalmus maximus L. The results showed that the maximum growth rate of 13. 52g ..d - 1 appeared on two..year..old f ish and the average growth rate is 6. 84g..d- 1. The body weight could reach more than 500g after 250 days, 1000g af ter one year, and 3000g after 2 years. The relat ionship of the body length and the weight isW= 0. 0314SL3. 0972, and the relationship of total length and body length is TL= 1. 1839SL+ 0. 5012; BD= 0. 8512TL- 1. 0358 showed the relationship between body depth and total length. Von..Bertalanf fy equation is Lt = 49. 2294 ( 1 - e- 0. 7106 ( t 0. 2211) ) , Wt= 6186. 2350( 1- e- 0. 7106 ( t 0. 2211) ) 3. 1609, the growth f lection point of the body weight locates on 1. 3984, the industrially farmed turbot should be harvested after the growth flection point , which matches both economy principle and consumption habit. In addition, growth difference was analyzed between nature and farmed groups by growth character index .... integrated with K and L.. . The result s showed that farmed group grew significantly faster than natural group since there are better conditions under artificial control.
