  • Subtropical; Weight (g) - Total Length (cm) relationship: W = 0.00814*TL^3.071 (ref: fishbase)
  • Both eyes can be dextral or sinistral (left or right side of body) (ref: ADW)


  • Males are assumed to differ from females by {p_Am} and E_Hp only
  • The reproduction rate seems very small for a big fish with tiny eggs
  • In view of low somatic maintenance, pseudodata k_J = 0.002 1/d is replaced by pseudodata k = 0.3
