Fisheries Report No 64 - The Western Rock Lobster Fishery 1977 - 1978, R. S. Brown, E H. Barker

Fisheries Research Reports

The fishery for the western rock lobster Panulirus cygnus is one of the most important single fisheries in Australia and an important export earner for the State. The fishery is governed by a complex set of regulations which have been reviewed by Bowen (1971) and which are designed to limit the total fishing effort to acceptable levels and to enforce a legal minimum size. It is thus important to constantly monitor the state of the fishery both to ensure that the effort is remaining within the accepted limits and that the regulations are adequately performing their function of maintaining reasonably …

Fisheries Report No 67 - The Western Rock Lobster Fishery 1978 - 1979, R. S. Brown, E H. Barker

Fisheries Research Reports

The fishery for the western rock lobster Panulirus cygnus is one of the most important single fisheries in Australia and an important export earner for the State. Western Australia produced a record 11 388 tons in 1978/79, out of a total Australian catch of rock lobster of 15 400 tons. The fishery is governed by a complex set of regulations which have been reviewed by Bowen (1971) and Hancock (1981) and which are designed to limit the total fishing effort to acceptable levels and to enforce a legal minimum size. It is thus important to constantly monitor the state of …

Abundance, Biomass, And Diversity Of Aquatic Invertebrates In Level Ditches And Adjacent Natural Emergent Marsh In An Eastern South Dakota Wetland, Michael R. Broschart

Electronic Theses and Dissertations

The aquatic invertebrate communities of level ditches and adjacent natural emergent marsh in a South Dakota prairie wetland were sampled during the summer of 1982. Collections were made in both the water column and the bottom substrates. Forty-five taxa were collected. Analysis of variance indicated that a significantly greater mean number of taxa and a larger mean number of all macroinvertebrates were present in level ditches than in the natural emergent marsh. No differences were detected for mean biomass of all macroinvertebrate taxa collectively. Several taxa had a greater mean number and biomass in the level ditches than in the …

Factors Affecting Water Quality And Microinvertebrate Distribution Within A Small Black Hills Stream, Henry G. Drewes

Electronic Theses and Dissertations

A comparative evaluation of the benthic macroinvertebrate fauna was conducted concurrently with a physiochemical investigation on Slate Creek, Pennington County, South Dakota in the Black Hills. Water quality differences between years and among stations were detected in Slate Creek from both physiochemical and macroinvertebrate evaluations. The primary sources of disturbance to the Slate Creek study site during the sampling period were landscaping activities within the Deerfield Park Resort development and livestock activity. Increased runoff and elevated stream flows in 1982 were responsible for the variation in water quality between years. Water quality differences among stations indicated significantly (P < 0.05) higher turbidity and temperature immediately below the development site in 1981 and 1982. Significantly (P < 0.05) higher fecal coliform bacteria counts were observed at station 5 for both years, resulting from increased livestock activity. Phosphates and nitrates were highest at stations 4 and 5 but were not significantly (P > 0.05) different …

Rainbow Trout Cage Culture And Benthic Production In East-Central South Dakota Dugouts, Glenn David Schuler

Electronic Theses and Dissertations

Forty-five cages, encompassing 1.0 m3 of water, distributed between three dugout ponds, were stocked with rainbow trout (Salmo gairdneri) fingerlings to determine the feasibility of raising annual fish crops. Growth rates were compared between feeding rate (0, 3, and 5% body weight/day [bwt/day]) and stocking rate (35, 52, and 70 fish/cage). Growth was significantly (P ≤0.05) greater at feeding rates of 3 and 5% bwt/day than 0% bwt/day. The fish fed 0% bwt/day decreased in mean weight by 0.7 g; the weight gain for the 3 and 5% bwt/day feeding rates were 47.2 and 45.2g, respectively. Significant differences (P ≤ …

Small Mammals In Prairie Wetlands: Habitat Use And The Effects Of Wetland Modifications, Grey W. Pendleton

Electronic Theses and Dissertations

Although well documented for other habitat types, small mammal habitat use patterns in prairie wetlands are poorly understood. The distribution of the mammal fauna of South Dakota is also not well known. Because of the lack of information in these areas, evaluation of the impacts of wetland modifications on the resident mammal community is not possible. The objectives of this study were (1) to document the species composition and abundance of small mammal communities inhabiting prairie wetland basins, (2) to determine the effects of small scale habitat modification on small mammals, (3) and to explain local species distribution patterns using …

Factors Affecting Reproductive Success Of Bonytail Chubs And Razorback Suckers In Lake Mohave, Michael A. Bozek, Larry J. Paulson, James E. Deacon, U.S. Department Of Interior, Fish And Wildlife Service

Publications (WR)

Razorback suckers (Xyrauchen texanus) and bonytail chubs (Gila elegans) were once widespread throughout the Colorado River system. The ranges and populations of these native species and others have declined in the past 50 years. Bonytail chubs appear to be extremely rare and possibly nearing extinction in the Upper Colorado River Basin. The razorback sucker is widely distributed in the upper river but is considered rare throughout most of that range and is also rare in the Grand Canyon. Razorback suckers are abundant only in a few habitats in the upper river. They congregate and spawn over …

Brood-Rearing Period Cover Use By Wild Turkey Hens In Southcentral South Dakota, Kevin Francis Mccabe

Electronic Theses and Dissertations

Brood-rearing period cover use by wild turkey (Meleagris gallopavo) hens with broods and those without, in Gregory County, South Dakota, was determined in order to formulate management suggestions for grassland/riparian woodland habitat. Two hens with broods and 12 hens without broods were studies through telemetry and direct observations form 5 July through 2 August and 3 August through 17 August of 1982 and 1982. Vegetational data were collected in 1983. Hens with broods selected for the grass/forb-dominated understory and 52% open canopy of south-facing savannah woodlands while their broods were less than 4 weeks of age. After 4 weeks, broods …

Intensive Culture Of Largemouth Bass And Walleye Fry In Experimental Systems, Gerald A. Wickstrom

Electronic Theses and Dissertations

Six genera of invertebrates were made available to largemouth bass (Micropterus salmoides) fry for 25 days. Brachionus spp. was selected for during both day and night (1100 and 2300 h) for the first seven days. Cyclops vemalis was selected on days 1 - 14; it was selected for more during the day for days 1 - 7. Daphnia pulex and D. magna were selected for during days 15 - 25. As the fry grew during the study they ate significantly (P < 0.05) larger D. pulex and D. magna. Moina brachiata was not selected for; it was eaten throughout the study in approximately the same proportion as available. Diaptomus spp. And Ceanestheriella setosa were not eaten. The fry increased in mean length from 6.5 mm on day 1 to 29.8 mm on day 25 of the study. Mean daily length increase was 0.93 mm. Newly hatched walleye (Stizostedion vitreum vitreum) fry were intensively cultured on a diet of live zooplankton under three conditions for 48 days. The fry were reared in tanks under constant illumination (375 lux), in tanks under reduced illumination (105 lux), and in tanks which contained visual interceptors (400 lux). Mean survival of walleyes was 14.0% in tanks under constant illumination, 11.6% in tanks under reduced illumination, and 4.7% in tanks which contained visual interceptors. Mean unaccountable mortality of walleyes was 21.8% in constant illumination tanks, 35.7% in reduced illumination tanks, and 27.4% in tanks with visual interceptors. The fry increased in mean length from 8.6 mm at the start of the study to 36.3 mm (0.76 mm/day) in constant illumination tanks, 36.6 mm (0.76 mm/day) in reduced illumination tanks, and 33.7 mm (0.70 mm/day) in tanks with visual interceptors after 48 days of intensive culture.

Food Selectivity Of Bluegill And Green Sunfish Fry, Aaron Barkoh

Electronic Theses and Dissertations

Four genera of zooplankton and cladoceran egg cases, collected from a municipal sewage lagoon, were made available as food to green sunfish (Lepomis cyanellus) and bluegill (Lepomis macrochirus) fry, to examine their food selectivity. Green sunfish and bluegill fry ranged in size from 8.5-11.0 mm and 8.0-10.5 mm at stocking and were reared for 31 and 30 days, respectively. The gut contents of 1488 green sunfish and 1440 bluegill fry, representing day and night samples were examined. Diet composition was evaluated using the linear food selection index. Both green sunfish and bluegill fry selected for Cvclops vernalis and consistently selected …

An Economic Valuation Of South Dakota Wetlands As A Recreation Resource For Resident Hunters, Craig W. Johnson

Electronic Theses and Dissertations

In spite of efforts to conserve wetlands, intensified agriculture, water projects, and urban development annually diminish the quantity and quality of wetland resources (Weller 1981). Leitch and Danielson (1979) noted that when the discounted value of the returns to drainage exceed drainage costs there is an economic incentive to drain. If present drainage rates continue, Weller (1981) estimated that most wetlands will disappear by the year 2140. Research has only recently focused attention on the need to estimate the public value of wetland benefits and the social costs of drainage (Leitch and Danielson 1979). The disparity between private and social …

Angler Harvest Survey Of Lake Francis Case, South Dakota, Lawrence M. Miller

Electronic Theses and Dissertations

An angler harvest survey, consisting of two independent surveys, was conducted on Lake Francis Case, South Dakota, from May through October 1981, and April through October 1982. An aerial angler count was used to estimate angle pressure, and an angler interview survey was used to estimate catch rate. In 1981, a section of Lake Francis Case in the vicinity of the Gregory County Pump Storage Project (Zone 2) was surveyed. IN 1982, the survey was expanded to include the entire reservoir (additional Zones 1 and 3). Estimated fishing pressure for Zone 2 in 1981 was 188,631 angler-hours and in 1982 …

Use Of Eastern South Dakota Shelterbelts By Nesting Birds Of Prey, Scott E. Norelius

Electronic Theses and Dissertations

This study was conducted in 1979 and 1980 to determine abundance, productivity, food habits, and ranges of raptors utilizing shelterbelts were in a 78 km² Brookings County study area.

The Red River Gorge: The Existence Of "Recreational Niches" And Their Management Implications, Sara E. Alexander, Billie R. Dewalt, Eugenie Scott

KWRRI Research Reports

Until the late 1960's, the Red River Gorge was just one of the more beautiful parts of the Daniel Boone National Forest. At this time, the Army Corps of Engineers proposed to dam the river for flood control, water supply, and recreation purposes. Intense opposition to the project generated considerable publicity and the Gorge area experienced substantial increases in visitation. The result has been not only severe environmental degradation but extensive overcrowding as well. These trends are presently overtaxing management capabilities of the United States Forest Service. The most pressing issue has come to be how to effectively manage this …

Climate Model For Winter Wheat Yield Simulation, Kenneth G. Hubbard, R.J. Hanks

School of Natural Resources: Faculty Publications

Winter wheat yields were simlulated by a model requiring climatic data as input for estimating crop evapotranspiration and phenological development. An assumed relationship between the winter wheat yields and the amount and timing of crop water use was optimized to simulate yields for two case studies: a single season, irrigated wheat study, and a multi-year, dryland wheat study. The model explained more than 90% of the variance of wheat yields in the irrigated study where total irrigation amounts varied between 0 and 55 cm. About 40% of the variance was explained for annual yields from a 21-year, dryland winter wheat …

Spatial And Temporal Variations In Long-Term Normal Percent Possible Solar Radiation Levels In The United States, Robert C. Balling, Randall S. Cerveny

School of Natural Resources: Faculty Publications

The purpose of this study was to analyze the time and space variations in long-term monthly-averaged daily percent possible solar radiation levels in the United States. Both principal components analysis and harmonic analysis were used to identify the influences of various synoptic-scale climatological phenomena on solar radiation receipt. Generally, an annual cycle was found with maximum percent possible radiation levels occurring in July. In many regions the temporal variance structure deviated from this general annual cycle. The results, which are useful in both theoretical and practical studies, lead to a better understanding of the climatology of solar radiation in the …
