Food Of Largemouth Bass (Micropterus Salmoides) In Degray Reservoir, Arkansas, 1976, Horace E. Bryant, Thomas E. Moen
Food Of Largemouth Bass (Micropterus Salmoides) In Degray Reservoir, Arkansas, 1976, Horace E. Bryant, Thomas E. Moen
Journal of the Arkansas Academy of Science
Stomach contents were examined from 748 largemouth bass, Micropterus salmoides (<125 mm total length), collected from DeGray Reservoir during April-November 1976. Fish constituted 59% by weight of the total diet and occurred in 81% of the stomachs; crayfish made up nearly 38% of the weight and occurred in 24% of the stomachs. Sunfish, the principal fish food (about 28% by weight), were observed in 36% of the stomachs. Shad were the second most important prey (23% by weight and 29% frequency in occurrence). Crayfish constituted about 42% of the total weight of the food of bass 200 mm long or longer, but only 12% in bass less than 200 mm. Crayfish consumption was greatest during the fall.
Potential Of Utilizing Scrap Processed Cheese As A Major Ration Component For Channel Catfish, Calvin J. Haskins, Scott H. Newton
Potential Of Utilizing Scrap Processed Cheese As A Major Ration Component For Channel Catfish, Calvin J. Haskins, Scott H. Newton
Journal of the Arkansas Academy of Science
Three cages (0.9 m³) were stocked with 200 channel catfish, Ictalurus punctatus Rafinesque, fingerlings (73.7 g avg.) in a 1.5 hectare pond. Two cheese rations were formulated and fed to the catfish; the first consisting of cheese, oil, and vitamin C (C + VC)and the second consisting of cheese, cottonseed meal, oil, trace minerals, and vitamins (CC + VM). A commercial trout ration (TC) was fed as a control. High mortalities occurred in the C + VC diet, thus resulting in premature removal of that cage from the study (after 86 days). A sample of 50 fish from the two …
Food Of Bluegill And Longear Sunfish In Degray Reservoir, Arkansas, 1976, Horace E. Bryant, Thomas E. Moen
Food Of Bluegill And Longear Sunfish In Degray Reservoir, Arkansas, 1976, Horace E. Bryant, Thomas E. Moen
Journal of the Arkansas Academy of Science
Stomach contents were examined from 544 bluegill (Lepomis macrochirus) and 709 longear sunfish (L. megalotis) collected from nearshore areas of DeGray Reservoir April-November 1976. Major foods of bluegill (percentage of total weight of food in parentheses) were insects (33), bryozoa (7.3), planktonic crustaceans (6.5), and plant materials (15.4). The major food items contributing to the diet of longear sunfish were insects (52.6%), crayfish (12.5%), fish (7.4%), and plant material (6.7%). Although bluegill and longear sunfish are closely related species, their diets were not as similar as expected: bluegill consumed zooplankton, adult dipterans, and adult ephemeropterans associated with limnetic areas; while …
Evaluation Of A Full-Fat Soybean Ration For Channel Catfish Production In Cages, Scott H. Newton, Walter R. Robison, Calvin J. Haskins
Evaluation Of A Full-Fat Soybean Ration For Channel Catfish Production In Cages, Scott H. Newton, Walter R. Robison, Calvin J. Haskins
Journal of the Arkansas Academy of Science
An experimental ration consisting of 50% full-fat soybeans, heated 170°C, was compared to a commercial trout chow in a 120-day feeding trial using two stocks of channel catfish, Ictalurus punctatus Rafinesque. Catfish were reared in 0.9 m³ floating cages, with 200 fish per cage, anchored in a 1.5 hectare farm pond. A Central Arkansas stock significantly outperformed a Southeast Arkansas stock for comparisons of net production and food conversion efficiency (FCE), with 92% greater production and 41% better FCE, respectively. Survival was 90% or greater for all fish. There was no significant difference in dress-out weight between the stocks. However, …
