PRELIMINARY RESULTS OF A LIFE HISTORY STUDY OF THE SOUTHERN PLAINS CRAYFISH, PROCAMBARUS SIMULANS (CRUSTACEA: DECAPODA), FROM WEST-CENTRAL TEXAS
This study was undertaken to better understand the life history strategy of the southern plains crayfish, Procambarus simulans, from the Concho River drainage of west-central Texas. The population, inhabiting three temporarily contiguous pools along an approximately 5.5km reach of Dry Lipan Creek, an ephemeral tributary of the Concho River near Mereta, Texas was monitored within the first ten days of each month starting in April of 2016 and continuing through March of 2017. Specimens were collected, using minnow traps or burrow excavation, sexed, measured and then released. Males were determined as either form I (breeding) or II (non-breeding). Also, morphometric measurements of carapace length and width, abdomen length and width, chelae length, palmar width, and dactyl length were taken for each specimen. Both Form I and Form II males were observed consistently throughout the study; ovigerous females were observed only during September. Young-of-the-year were observed in both October and November. As water levels within the pools dropped during the winter months, specimens were less readily collected. The largest sample size (n=31) was observed in August and the smallest sample size (n=2) in January.
