Twelve 0.005‐hectare earthen ponds with established crawfish populations [Procambarus clarkii (Girard)] were drained in June 1973 and four each were flooded on 1 September, 1 October, and 1 November 1973. Substantial numbers of bait‐size (5.0–7.0 cm total length) crawfish were available from early October through May 1974 when ponds were drained. Population dynamics differed considerably from previously reported studies and are discussed. Trapping was selective for nonmolting crawfish and is the recommended harvesting technique if crawfish are to be held for over 1–2 days.
