  • The correlations between the height of the otolith and the height of the fish and length of otolith and length of the fish indicate that otolith and fish grow in parallel. While both otolith and fish growth might pause in unison it cannot be argued that the otolith continues to grow after the fish has stopped growing. Fig. 8(A) Fig. 8(B

  • Otoliths of adult fish were ground by hand on a glass plate covered with a water-silicon carbide powder mixture ( grit). The final polish may be administered with diamond paste but this step is not essential. The ground otolith was then examined in immersion oil. The grinding was done in the same plane as described by Pannella (1974).
