Comparison of Relative Contribution, Growth, and Vulnerability to Angling of Triploid Florida Largemouth Bass and Diploid Northern Largemouth Bass Stocked in a Newly-renovated Reservoir

An evaluation was conducted to compare relative contribution, growth, and vulnerability to angling of triploid Florida largemouth bass (Micropterus salmoides floridanus) and diploid northern largemouth bass (M. s. salmoides) when stocked together in a newly-renovated reservoir. Triploid Florida largemouth bass were stocked in Lake Balmorhea, a 213-hectare reservoir in West Texas, for five consecutive years and failed to recruit in all years except the initial stocking year. Diploid northern largemouth bass were stocked only in the first year and produced significant year classes in years 4...


Evaluation of Fertilizers to Increase Plankton Abundance in Reservoir Coves

A study was conducted in Lake Benbrook and Squaw Creek reservoirs, Texas, to determine whether naturally occurring phytoplankton and crustacean zooplankton abundance in selected coves could be increased by fertilization. In each reservoir, I cove was fertilized once a week for 4 weeks using inorganic fertilizer (liquid 10-34-0, N-P- K, applied at I mg/liter PP,), 1 cove was fertilized with the same inorganic fertilizer plus organic fertilizer (cottonseed meal applied at 225 kg/ ha), and I cove received no fertilizer as a control. Nutrient and plankton levels in the coves were monitored...


Evaluation of Fertilization Techniques used in Striped Bass, Florida Largemouth Bass, and Smallmouth Bass Rearing Ponds

A study was conducted in 9 striped bass (Morone saxatilis), 7 Florida largemouth bass (Micropterus salmoides floridanus), and 6 smallmouth bass (M. dolomieui) rearing ponds to evaluate the effects of various traditional and experimental fertilization regimes utilizing both organic and inorganic fertilizers. No significant differences were found in water quality, zooplankton populations, or fingerling production among any of the fertilization treatments. All treatments produced adequate zooplankton densities for fry survival and growth without detrimental effects on water quality. Low...


Factors Affecting Fish Populations In Flood Prevention Lakes Of North-Central Texas

During summer, 1976, limnological and fish population data were obtained from 56 flood prevention lakes of the Trinity River watershed. Fish samples obtained by gillnetting, electrofishing, and seining indicated that the principal fishes were largemouth bass Micropterus salmoides), bluegill (Lepomis macrochirus), black bullheads (Ictalurus melas), white crappie (Pomoxis annularis), green sunfish (Lepomis cyanellus), channel catfish (lctalarus punctatus), golden shiner (Notemigonus crysoleucas), and redear sunfish (Lepomis microlophus). Analysis of fish data was performed by simple and...
