Use of Mortality Caps to Determine Effectiveness of Black Bass Harvest Restrictions in Tennessee Reservoirs

Evaluations were made of management objectives across Tennessee for 25 largemouth bass (Micropterus salmoides) populations and 7 smallmouth bass (M. dolomieu) populations. Two models were used; one that calculated mortality caps based on target mean lengths and one based on minimum acceptable PSD or RSD. Mortality caps were calculated over a range of target mean lengths and PSD/RSD objectives and results from each model discussed. Both models suggested that current harvest restrictions for most populations were sufficient to protect fish up to at least 25.4 mm beyond current length limits...
