The reproductive biology and growth of the Mississippi Silvery Minnow, Hybognathus nuchalis, is described from multiple sites in the Pearl River, Louisiana. Individuals were collected from August 2011 to August 2012. Ovarian weights, expressed as a percentage of body weights, peaked in December. Size structure ranged from 29.0 to 60.0 mm SL for females and 25.0 to 56.0 mm SL for males. Mature ova were found from November to January. Females reached first maturity (L50) at 37.0 mm SL and L50 for males is at 41.0 mm SL. Sex ratio (females:males) is biased towards females (X2= 18.57 p …

Distribution records for 15 fish species of conservation interest are included for Kentucky. Notropis dorsalis, previously undocumented in Kentucky, is reported for the first time (Mayfield Creek drainage). Also reported are state rediscoveries of three species thought to be extirpated from Kentucky: Ichthyomyzon gagei (Tennessee River drainage), Hemitremia flammea (Lower Cumberland and Green river drainages), and Hybopsis amnis (upper Cumberland River drainage). Unreported drainage records comprise nine species: Ichthyomyzon castaneus (Salt River drainage and Upper Green River drainage); Ichthyomyzon unicuspis (Salt River drainage and upper Big Sandy River drainage); Campostoma pullum (Tennessee River drainage); Umbra limi (Obion Creek drainage); …
