The Biology Of The Roanoke Bass, Ambloplites Cavifrons Cope, In North Carolina

This paper summarizes the final report on the investigation of theRoanoke bass in North Carolina. It contains new data on recognitioncharacters, distribution, food studies, sexual maturity, and age-andgrowthstudies which essentially augments the report "A PreliminaryReport on the Biology of the Roanoke Bass, Ambloplites cavifrons Cope,in North Carolina," Smith, 1969, presented in the 23rd SoutheasternProceedings, 1969.


A Preliminary Report On The Biology Of The Roanoke Bass, Ambloplites Cavifrons Cope, In North Carolina

The Roanoke bass, Ambloplites cavifrons, was described by Cope in 1867 seemingly from a single three-inch specimen recovered from the Roanoke River in Montgomery County, Virginia. Subsequent literature indicates the species remained unrecognized in North Carolna until 1963 when encountered in Fishing Creek during a survey and inventory of the Tar River Basin. Inquiry among local anglers and Wildlife Protectors has revealed this fish apparently is taken by rod-and-reel fishing in small-to-moderate numbers from several diverse streams of both the Tar River Basin and the Neuse River Basin....


Premature Egg Procurement From Striped Bass

Striped bass were successfully ovulated in Albemarle Sound, North Carolina some 150 miles from their natural spawning grounds and about one month before their normal spawning time. Brood fish were purchased from commercial fishermen, consequently the eggs so obtained were salvaged out of a sacrificial situation. The fish were collected from pound nets following narcosis by electric shock; the narcosis being maintained by the addition of Quinaldine to the water in the boat holding tank until the female fish had been injected with human chorionic gonadotropin at the egg taking station...


Preliminary Experiments in the Artificial Propagation of Striped Bass, Roccus Saxatilis

Adult striped bass purchased from commercial fishermen on Albemarle Sound, N. C. were transported to the Fayetteville and Weldon Hatcheries, injected with hormones,and spawned. In addition to ripe fish brought into the Weldon Hatchery by fishermen, sexually mature striped bass were obtained from the Roanoke River by electro-fishing gear. These fish, like those from Albemarle Sound, were injected with hormones, held in glass-front plywood aquaria (32" x 24" x 16"), and spawned. Excellent hatches were obtained from these eggs. Laboratory experiments, confirmed by actual practice,...
