| Abstract |
The length distributions of seven populations of largemouth bass Micropterus salmoides in small impoundments in Texas were investigated through the use of daily otolith rings. Daily rings were recognizable by microscopic observation as long as growth continued, up to 184 days in one population. The difference in age between the oldest and youngest fish within a sample, reflecting the length of the spawning period, ranged from 15-68 days. Comparison of samples of fish of similar mean ages indicated that those populations with short spawning periods subsequently exhibited less variation in total lengths than populations with longer spawning periods. Length distributions were typically characterized by a significant correlation between length and age. |
