Fish Community Structure and Zonation Related to Stream Habitat

Twenty-seven quantitative fish collections and site habitat analyses were performed from October 1985 to April 1988 in the Little Missouri River in Southwest Arkansas. Longitudinal addition of fish species (from 9 to 30) corresponded to downstream change in physical habitat. Species diversity increased from headwaters to midreaches and was positively correlated with increasing stream size, decreasing particle substrate size, depth, and development of alluvial riffle/pool morphology. The prime factor associated with the increasing fish species diversity was the corresponding increase in...


Evaluation of Marone Hybrids in a Small, Shallow, Warmwater Impoundment

Fingerling Morone hybrids were stocked into Storm Creek Lake, Phillips County, Arkansas, to control a nuisance gizzard shad (Dorosoma cepedianum) population and diversify the sport fishery. The lake, a 169.7-ha shallow, warmwater impoundment, was stocked with 31,000 hybrids during a 4-year period (1982, 1984, 1985, and 1987). Growth during their first 3 years was rapid (age 1-325 mm; age 11-428 mm; age III-591 mm). Number of age IV fish (602 mm) declined over time. Due to high water temperatures, low dissolved oxygen levels, and shallow nature of the lake, hybrid populations were not...


Restoration of Warm Water Lakes and Ponds on the National Forests in Mississippi and Louisiana

The U.S. Forest Service has been trying to improve the fish population structure of 120 flood control lakes and ponds in the National Forests of Mississippi and Louisiana. Recent efforts have included supplemental stocking, complete eradication of existing populations followed by restocking, and selective species eradication. Since 1978, 36 lakes, 25 ponds and 59 livestock and wildlife watering ponds varying in size from 0.1 to 940.5 ha have undergone fish population alteration. Fifty-three of these lakes and ponds were completely restocked, while 57 have received supplemental stocking....
