Facts

  • dioecious, which means that each individual is either male or female (ref: Wiki)
  • weight-length: weight (g): W = 0.0028 * (radius in mm) ^2.4743 = 0.8346 * (radius in cm) ^2.4743 (ref: BosGuma2008)

Discussion

  • In view of changes in shape during growth, radius length is converted to volumetric length
  • In view of low somatic maintenance, pseudodata k_J = 0.002 1/d is replaced by pseudodata k = 0.3
