Age and growth of spotted sand bass, paralabrax maculatofasciatus, in Bahia de Los Angeles, Baja California, Mexico, with age validation using Otolith edge analysis.

Abstract.--Spotted sand bass, Paralabrax maculatofasciatus, were mustered from Bahia de Los Angeles, Baja California, Mexico covering as wide a size range as possible above four seasons (spring, summer, fall, and winter). Age was estimated and extension parameters calculated from extension zones counted in transverse otolith sections. An otolith cutting side analysis indicated an opaque increase zone was deposited once by year during the summer validating the annual periodicity. Spott sand bass from this region are fast growing with a relatively short life span of up to 11 years. extension ...
