Criteria For Rodent Bait Selection, W.R. Smythe

Vertebrate Pest Conference Proceedings: 7th (1976)

World food shortages become more acute each year, and all too often, rodents are present to take their unwarranted share. To counter this, we must refine our rodent control methods to make them more efficient. To this end, correct bait selection is essential. Grain baits must be selected for purity and acceptability. Grain alterations must be carefully controlled, as well as any additives. Multi-ingredient or composition baits must be checked for size, hardness, protein content and additives. The selection of trap baits is critical for the success of trapping program. In general, fresh coconut is the best bait, but on-site …

Keynote Address—The Role Of Education In Vertebrate Pest Control, Gustav A. Swanson

Vertebrate Pest Conference Proceedings: 7th (1976)

Lack of adequate information is emphasized as a major problem in attaining effective control of damage by vertebrate pests, and it is stressed that the problem is widespread in all elements of the public, including those directly involved, like producers and government officials, as well as those only indirectly involved, like the average citizen. A number of specific examples are cited to illustrate the problems of uninformed or inadequately informed publics.

Anticoagulants—A Problem Of Distribution For The Hawaiian Sugar Industry, Allen H. Teshima

Vertebrate Pest Conference Proceedings: 7th (1976)

Current rodent control practices for the Hawaiian sugar industry revolve around the use of single grain baits containing anticoagulants in bait stations and zinc phosphide for aerial applications. Neither type of control programs as they are now applied has been very effective against the Norway rat (Rattus norvegicus) which is becoming a major problem species for the industry. As a result, we have sought a more effective anticoagulant, to which the Norway rat is more susceptible, and an improved method of bait distribution. With knowledge of the month-to-month variation in the field rodents' gestation rate, a new control …

The Cost Of Predator Damage Control Using Trapping As The Primary Control Technique, Ronald A. Thompson

Vertebrate Pest Conference Proceedings: 7th (1976)

The justification and economics of the operational animal damage control program in California as conducted by the U.S. Fish and Wildlife Service are discussed. Emphasis is given to the necessity for use of the steel trap. Nearly 83 percent of the depredators are taken by trapping. Annual agricultural losses due to predation were estimated at $4.7 million in California for Fiscal Year 1975. The projected cost-benefit ratio was 1:3.9.

The Use Of Aircraft In Predator Control, Dale A. Wade

Vertebrate Pest Conference Proceedings: 7th (1976)

Private aerial hunting of predators for protection of livestock began before 1925 in the western United States. Apparently, it was first used in professional control programs in 1942. Inclement weather, dense vegetation and rough terrain are limiting factors and helicopters are more versatile than fixed-wing aircraft. When it can be employed, aerial hunting is unsurpassed as an immediate control method where livestock losses are severe and the need for control is urgent.

Control Methods For Nuisance Beaver In The Southeastern United States, Edward P. Hill

Vertebrate Pest Conference Proceedings: 7th (1976)

Strychnine alkaloid baits were consumed by both captive and wild beaver without any apparent hesitation. An approximate minimal acute lethal dose of sodium monofluoro-acetate to beaver of mixed ages and sex was 0.202 mg/kg. Trapping beaver on four study area watersheds in Alabama with No. 330 conibear traps for approximately two weeks in winter during two successive years essentially eliminated beaver. Older individuals were trapped the first year, maturing juveniles and the remaining few adults were trapped the second year, and there was very little reproduction between the trapping periods. Trapping, with its recreational appeal, and income and food potential …

Pharmacological Review Of Chemicals Used For The Capture Of Animals, Peter J. Savarie

Vertebrate Pest Conference Proceedings: 7th (1976)

A review of the literature reveals that over 60 chemicals have been used for the capture of wild animals, but only 30 of the most widely used chemicals are discussed in the present paper. For practical considerations these chemicals can be classified as being either (l) neuromuscular blocking agents, or (2) central nervous system (CNS) depressants. Some common neuromuscular blocking agents are d-tubocurarine, gallamine, succiny1choline, and nicotine. M99 and its derivatives, phencyclidine, and xylazine are some of the more commonly used CNS depressants. Neuromuscular blocking agents have a relatively rapid onset and short duration of action but they do not …

Some Of The Effects Of Domestic Sewage Discharged Into Hickman And Jessamine Creeks In Jessamine County, Kentucky, Henry H. Howell, Mike W. Jones, Robert A. Kuehne

KWRRI Research Reports

A 6-week study was made in the summer of 1971 as an initial effort to determine the extent of pollution that the three sewage disposal plants in Jessamine County, Kentucky, are contributing to its streams. With the rapid population increase in Lexington and nearby municipalities, this study should furnish a basis of comparison for future investigations. Eighteen collecting stations were established in riffle areas of Hickman and Jessamine Creeks, and coliform bacteria, macro-invertebrate populations, fish populations and chemical water quality of each riffle area were studied.

Hickman Creek's flow was augmented by approximately 3,100,000 gallons/day (11,735 -m³/day) from …

An Evaluation Of The Effects Of Dredging Within The Arkansas River Navigation System, Volume Iv - The Effects Upon The Benthic Associations, Louise Russert Kraemer

Arkansas Water Resources Center Technical Reports

The huge and increasing volume of dredged materials being moved in and from the bottoms of waterways of the U.S. is probably well known to the reader. Lee and Plumb (1974) distinguish between the 2 forms of dredging: (1) mining the bottom sediments (as in shell dredging), and (2) developing and maintaining navigable waterways. They indicate some 380,000,000 cubic yards are dredged annually in this country; maintenance dredging accounting for about 80,000,000 cy, and new construction for about 300,000,000 cy.* These figures (based on 5 yr. averages) do not include dredging by private companies. Smith (1975) comments: "With federal dredging …

An Evaluation Of The Effects Of Dredging Within The Arkansas River Navigation System, Volume V - The Effects Upon The Fish Population, Thomas M. Buchanan

Arkansas Water Resources Center Technical Reports

The Arkansas River extends for 1,450 miles from the eastern slopes of the Rocky Mountains in Colorado, southeasterly through Kansas, Oklahoma, and Arkansas, where it enters the Mississippi River in Desha County. The 448 mile navigation channel which was constructed on the lower portion of this river includes portions of two of its major tributaries, the Verdigris River in Oklahoma and the lower White River in Arkansas. The Arkansas portion of this navigation system consists of three different segments: (1) the lower White River, from its confluence with the Mississippi River to 10 miles upstream, (2) the Arkansas Post Canal, …

Fisheries Report No 22 - The Western Rock Lobster Fishery 1971 - 1972, G. R. Morgan, E H. Barker

Fisheries Research Reports

The fishery for the western rock lobster* 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 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 stable catches. Inherent …

Fisheries Report No 25 - The Western Australian Amateur Fishery For Australian Herring (Arripis Georgianus) - Results Of The 1973 Creel Census, R C.J. Lenanton, N. G. Hall

Fisheries Research Reports

Historically, the Western Australian production of Australian herring (Arrtpts georgtanus) has fluctuated from year to year in response to changing market demand. Prior to 1968, the annual catch taken by professional fishermen was relatively stable, ranging from 200 000 kg (approx. 500 000 pounds) to 450 000 kg (approx. 1 000 000 pounds). From 1968, commercial production has risen to a peak of 1 187 440 kg (2 617 857 pounds) recorded in 1972/73 (Table I). An increase in demand for herring as bait for the rock lobster fishery is considered to be the major factor involved in this observed …
