Douglas Lake - Trap Netting 2015

 

The TWRA used trap nets to sample Douglas Reservoir’s crappie populations in early November. These nets were set between Nina Creek and the dam. Five hundred and twenty-eight black, 359 white, and five black-nose crappie were collected in the 90 trap net sets.

Sixty-two percent of the black crappie in the sample were between 6- and 10-inches in length indicating good natural reproduction occurred in 2013 and 2014. Approximately 27% of the black crappie were less than 5-inches, suggesting a strong year class was also produced in 2015. White crappie exhibited good reproduction in 2015 given 93% of those collected were less than 5-inches.

Douglas has produced strong year classes during each of the past four years. Good overall numbers coupled with the presence of large numbers of young-of-the-year fish, demonstrates that Douglas crappie continue to show signs of recovery.
