A volunteer angler diary program was evaluated as a data source compared to traditional fisheries census techniques (i.e., electrofishing, gill netting, and on site creel surveys). Anglers were supplied fishing diaries and asked to record lengths of fishes caught, location, and time fished in Texas public waters, 1986-1988. Volunteer angler-supplied (ANG) length and catch-per-unit-effort (CPUE) data were then compared to traditional fisheries census data for the same season and water body. Although ANG data were reported for 4,581 trips, 144 reservoirs, and 10 species or species groups,...

During summer, 1976, fish population data were collected by gillnetting, electrofishing, and seining from 30 flood prevention lakes that maintained coexisting populations of white crappie (Pomoxis annularis), largemouth bass (Micropterus salmoides), and bluegill (Lepomis macrochirus). Abundance and size composition characteristics for white crappie were compared by simple correlation techniques to abundance and size composition characteristics for largemouth bass and bluegill Total numbers of white crappie were not significantly correlated to total numbers of largemouth bass or bluegill...
