The Presence Of Micropterus Salmoides (Largemouth Bass) Influences The Populations Of Rana Draytonii (California Red-Legged Frog) And Pseudacris Regilla (Pacific Treefrog) In Two Ponds In Santa Barbara County, California, Kenneth Lee Gilliland
Master's Theses
Alien fish have been implicated in the decline of Rana draytonii (California red-legged frog) and Pseudacris regilla (Pacific treefrog) populations. Micropterus salmoides (largemouth bass) is a common sport fish that has been introduced into the sympatric range of these two anuran species; however, no studies have investigated the individual influence that this alien fish has on these two species. I conducted M. salmoides control or eradication experiments during a four year study in two ponds within the Transverse Mountain Range of Santa Barbara County, California. Changes in the densities of all life stages of R. draytonii and P. regilla were …
Growth And Food Habits Of Micropterus Salmoides In Westhampton Lake, Richmond, Virginia, Charles H. Rawls
Growth And Food Habits Of Micropterus Salmoides In Westhampton Lake, Richmond, Virginia, Charles H. Rawls
Master's Theses
Age, growth, and food habits of the population of Micropterus salmoides (largemouth bass) in Westhampton Lake were studied from September to November, 1978. Two year classes (O and I) were identified by determining numbers of annuli on the scales of the fish. Growth data indicated that the bass attain a size of 254 mm (10 in.) near the end of their second summer. The length-weight relationship was log W = - 4.6829 + 2.9153 log TL. The Fulton condition factor for the population was 1.40. Food habits were described by numerical and frequency of occurrence methods. Young of the year …
