To determine age and growth rate of the white-blooded fish from their otoliths, some special techniques of otolith preparation is called for. Decalcination in 5% HNO3 yields positive results for Chaenocephalus aceratus only. Burning of otoliths is suitable for Champsocephalus gunnari and Chaenocephalus aceratus, the best results being produced for Pseudochaenichthys georgianus.
