New Functions for the Analysis of Two-Phase Growth of Juvenile and Adult Fishes , with Application to Nile Perch

  title={New Functions for the Analysis of Two-Phase Growth of Juvenile and Adult Fishes , with Application to Nile Perch},
  author={MlNA and Jacques Moreau and JOHN M. HoENic},
—Two phases of growth can sometimes be distinguished in long-lived fish species. The first involves the growth of zooplankton-feeding juveniles and young adults. The second consists of accelerated growth of large, piscivorous adults. We present modified versions of the von Bertalanffy growth equation that account for this feature and fit them to length-at-age data on Nile perch Lates niloticus (Centropomidae) from Lake Chad (north and south) in north-central Africa, and from Lake Nasser in… CONTINUE READING
