AGE AND GROWTH DETERMINATION IN CITHARINUS CITHARUS (GEOFFREY AND ST. HILAIRE, 1809) IN ONAH LAKE, DELTA STATE, NIGERIA

Publication Ref: 
Trop. Freshwater Biol. 14:9-18.

 

An observation of the rings impressed on the polished sagittae otoliths of Citharinus citharus in the present study revealed reliable age data.  Two daily rings were counted on the otoliths.  These rings resulted from other factors including growth increments.  Two types of rings (periodic and daily) were described.  Two periodic rings were counted annually while the daily rings were impressed in multiples of two.  Growth increments were also observed on scales.
