Discussion

  • males are assumed to differ from females by {p_Am} only
  • I had to add 1.8 yr to ages estimates in tL data
  • The incubationtime 4.5 d leads to an estimate for v of 0.12 cm/d, which seems large; ab is ignored

Facts

  • length-weight: weight in g = 0.00562*(TL in cm)^3.05 (Ref: fishbase)
