Effects Of Starvation And Time At Stocking On Survival Of Stocked Rainbow Trout, Salmo Gairdneri, Marlin John Bricker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Investigations of effects of starvation and time at stocking on the survival of catchable rainbow trout in two areas of Mammoth Creek in Dixie National Forest, Utah, were conducted from May 24 to December 6, 1969. Fish were starved for 6 days and 1 day and stocked in the morning (5:40-7:00 a.m.) and in the afternoon (1:45-5:30 p.m.). Out of 7,000 tagged fish stocked, 4,751 tags were returned by fishermen. The 6-day starved fish, stocked in the morning returned to the creel in highest numbers (1,240); followed by 1-day starved, afternoon-stocked fish (1,194); 6-day starved, afternoon-stocked fish (1,163); and 1-day …

Some Ecological Relations Of Fairy Shrimps In Alkaline Habitats Of Nebraska, D. B. Mccarraher

Nebraska Game and Parks Commission: Staff Research Publications

Ecological studies on the distribution of fairy shrimps have been made from 246 sites in the sandhills region of Nebraska. New records for Nebraska have been established for Artemia salina, Branchinecta campestris, B. lindahli, B. mackini and Cyzicus mexicanus. Seasonal populations of shrimp have been located in habitats containing permanent fish populations. Water mineralization was the dominant environmental condition related to the distribution of phyllopods with sodium and potassium compounds predominating in the strongly alkaline lakes. Several of the Artemia lakes were classified as hydroxide sites. Many of the alkaline ponds, where B. lindahli and B. campestris flourish, are …

Effect Of Domestic Effluent On Two Spring Surveys Of Fishes In Lost Creek, Craighead County, Arkansas, John K. Beadles

Journal of the Arkansas Academy of Science

Lost Creek is representative of deltonic streams of the St. Francis Basin possessing characteristics of being turbid. It has a low flow velocity except during the annual spring rains. Lost Creek meanders approximately 18 km. before receiving effluents and empties into Big Creek approximately 4 km. west of Jonesboro, Arkansas. Five collecting stations were studied in 1966 while six stations were sampled in 1970. Some fishes have been found to tolerate moderate amounts of domestic effluents and it is probable that the two species Lepomis cyanellus and Ictalurus melas, collected within the effluents, were more resistant than the other species …

Reproductive Biology Of Thais Emarginata (Deshayes, 1839) And Thais Canaliculata (Dulcos, 1832), Roy Seamands Houston

University of the Pacific Theses and Dissertations

Thais emarginata (Deshayes, 1839) and Thais canaliculata (Dulcos, 1832), are two common Pacific coast gastropods (Family: Muricidae). T. emarginata is found in semi-protected rocky areas from Alaska to Baja California, while T. canaliaulata occurs in quiet bays from Alaska to Monterey Bay, California (Ricketts and Calvin, 1966). Both species occur on rocks and jetties where they can be seen feeding upon barnacles and young mussels. Despite the abundance of these species their reproductive biology has not been examined.

In the present study, the following aspects of the reproductive biology of T. emarginata and T. canalieulata are presented: Relationship of gonadal …

A New Genus Of Trematode (Digenea: Gorgoderidae) From The Ureter Of Tuna Fish (Thunnus Thynnus Maccoyii) In Australia, Harold W. Manter

Harold W. Manter Laboratory of Parasitology: Library Materials

A large, digenetic trematode is described from the ureter of the tuna Thunnus thynnus moccoyii from southern Australian waters. It represents a new genus and species, Cetiotrema crassum (subfamily Gorgoderinae) distinguished by the size and shape of the body, the caeca being distant from the sides of the body, the uterus being intercaecal, the vitellaria arising as three claviform lobes on each side and the seminal vesicle at least partly anterior to the genital pore.

The genus is close to Phyllodistomum Braun; P. carangi Manter, 1947, is considered to belong to Cetiotrema; P. lancea Mamaev, 1968 is very similar …

Fisheries Report No V (5) - Report On Marron In Farm Dams (Cherax Tenuimanus), N M. Morrissy

Fisheries Research Reports

A programme of selling marron (Cherax tenuimanus) to country dwellers for stocking farm dams, has been carried out by the Pemberton Trout Board for the past few years with considerable financial gain. In this case permission to sell the marron was granted by the Department of Fisheries and Fauna so as to encourage the provision of stocks of this large, freshwater crustacean for farmers in the dryer inland areas of the Southwest which are remote from sources of fresh fish and from natural stocks of marron.

The marron, however, have been sold indiscriminately, upon request, without any advice as to …

Phlyctainophora Squali Sp. Nov. (Nematoda, Philometridae) From The Spiny Dogfish, Squalis Acanthias, Dwight R. Mudry, Murray D. Dailey

Harold W. Manter Laboratory of Parasitology: Library Materials

Summary

Phlyctainophora squali sp. nov. is described from 23 female specimens recovered from the subcutaneous tissue of one of 440 Squalis acanthias caught off Los Angeles, California. This finding represents a new host and distribution for this genus. Phlyctainophora is placed in the family Philometridae on the basis of atrophication of vulva and anus, simple mouth, viviparity and location in tissue of fishes. The family diagnosis for Philometridae is amended to include Phlyctainophora which lacks an anterior ovary.

Meteorological Factors Controlling The Emergence Of The Eastern Spadefoot Toad, Scaphiopus Holbrooki Holbrookii Harlan, Larry Judy

Theses, Dissertations and Capstones

Scaphiopus holbrooki holbrookii, the Eastern Spadefoot, can exist in an area for many years before it is detected. Its apparent scarcity can be explained by its secretive, fossorial habitat, protective coloration, and nocturnal behavior. Spadefoots are present at the surface locally in small numbers on any one night. They emerge only when conditions are optimum. One authority has suggested that temperature, moisture, and barometric pressure exert control over emergence.

It was the purpose of this research to discover the most important meterorological parameters and investigate how they control the behavior of Scaphiopus.

Initially the response, emergence to breed was distinguished …

Fishery Report Iv (4) - Report On The Barramundi Fishery In Western Australia, N M. Morrissy

Fisheries Research Reports

Barramundi are widely distributed in rivers and estuaries in the semi-tropical and tropical regions of the Indo- Pacific from South China to the Persian Gulf and along the coast of northern Australia. The limiting factors to the distribution appear to be temperature and salinity.

On Models Of Commercial Fishing, Vernon L. Smith

Economics Faculty Articles and Research

Commercial fishing is characterized by three key economic and technological features that are relevant to the formulation of an economic theory of fish production. 1. A fishery resource, although conceivably exhaustible, is replenishable; that is, it is subject to laws of natural growth which define an environmental biotechnological constraint on the activities of the fishing industry. 2. The resource and the activity of production from it form a stock-flow relationship. The new growth in the population fish mass depends upon the harvest rate relative to natural recruitment to the stock. If the harvest rate exceeds the recruitment rate, the stock …

Mourning Dove Status Report, 1967, James L. Ruos, Duncan Mcdonald

The Value Of A Trout Stream Fishery, Archie Allen Dyer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The data analysis indicated that travel distance, user age, and user income level are important determinants of use of trout streams.

These variables were incorporated into regression analysis to develop a use-prediction model.

This use-prediction model was used to determine predicted use levels of sample streams. The predicted use levels combined with travel costs and expenditures on new fishing equipment were used to derive a statistical estimate of the demand schedules for the sample streams.

These statistical demand curves were subjected to consumer surplus procedures to determine the values of the sample streams.

Reviews Of Glenn L. Hoffman (1967). Parasites Of North American Freshwater Fishes., John Paling

United States Fish and Wildlife Service: Publications

'This manual', the author explains, 'is intended to be an aid to the identification of the freshwater fish parasites of North America'. Judged by this objective, the book will be an invaluable source of reference for workers in this field. However as it does not set out to cover the ecology of fish parasites and furthermore as it concerns itself mainly with the American fauna, this book will probably have only a limited appeal to readers of this Journal.

Eutrophication Trends Of Bear Lake, Idaho-Utah And Their Effect On The Distribution And Biological Productivity Of Zooplankton, David Nyquist

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Zooplankton of the littoral and limnetic zones of Bear Lake, Idaho-Utah, were collected over a 17-month period. Twenty-three species of zooplankton were recorded, as well as nine other species represented by both flora and fauna. At the time of sampling 17 physical and chemical parameters were also measured. Methods of analysis for the plankton and the environment are described and discussed.

The objectives of this project were fourfold:

1. To establish a record of the current zooplankton population before changes due to the increase of organic nutrients occur.
2. To compile a qualitative and quantitative standard against which future populations can be …

Fisheries Report No 3 - Western Australian Freshwater Fisheries, Donald D. Francois

Fisheries Research Reports

Most of the Australian States have a comprehensive system of inland waterways, Western Australia, however, is in a less fortunate position. True, the maps of the State show many rivers, but in much of the southern, more populous part, with no summer rain and no winter snow, the majority are virtually a chain of waterholes during the long summer months. At the same time, in a relatively small section in the south-west corner, there is a series of permanent streams flowing through what was originally dense forest. But apart from the three indigenous freshwater crustaceans, the marron (Cherax tenuimanus), the …

Some Helminths Of Itasca Park Fishes, Omer R. Larson

Journal of the Minnesota Academy of Science

A helminth survey was conducted'. on 12 species of fish taken from the waters of Itasca State Park. An abundant and varied helminth fauna was found, with 3 l parasitic forms identified to genus or species. By taxonomic groups these included, 20 trematodes, 5 cestodes, 2 acanthocephalans, and 4 nematodes. Every fish examined was parasitized, but yellow perch and rockbass possessed the greatest variety of helminths. Based on the results of this survey, several aspects of parasite life cycles, geographic distribution, and hast specificity are discussed.

Survey Of The Fishes Of Tomales Bay With Notes On The Life History Of The White Seaperch, Phanerodon Furcatus Girard, Tapan Banerjee

University of the Pacific Theses and Dissertations

Tomales Bay is situated in Marin County, about 40 miles north-west of San Francisco. This shallow bay averages about 1.5 miles in width and is about 12.6 miles in length, with an average depth of 12 feet (Johnson, Bryant and Hedgpeth, 1961). Oyster and herring comprise the main fishing industry, although the bay contributes a great amount of perch, smelt, halibut, and shark. Gill and seine nets are the most common gear used by fishermen.

The primary objectives of this study were: (1) to determine the species composition of the bay, and the relation between seining success at different localities …

Ultrasonic Tracking Of Migratory Fishes With An Internal Tag, Ross M. Horrall, H. F. Henderson, A. D. Hasler

School of Natural Resources: Faculty Publications

First paragraph:

A small ultrasonic tag, 9 mm by 40 mm in size, has been developed by members of the fish orientation group at the University of Wisconsin. The tag emits a continuous signal at approximately 65 kc/sec. The signal is received via a directional hydrophone and a high quality communications receiver. Tracking ranges of up to 1 km have been obtained. The placement of the tag is internal: either into the stomach or into the body cavity of the fish. The tags and tracking equipment have been successfully employed in studies on the open water movements and orientation of …

An illustrated synopsis of the known Microsporidea of freshwater and euryhaline fishes is given.

Eimeria Aurati N. Sp. (Protozoa:Eimeriidae) From Goldfish (Carassius Auratus) In North America, Glenn L. Hoffman

United States Fish and Wildlife Service: Publications

In March, 1962 this laboratory received some goldfish for disease diagnosis from Mr. Richard Rice, Mercersburg, Pennsylvania. Seven of 29 fish examined were infected with Eimeria. These fish had long, whitish, opaque fecal casts hanging from the anus. The casts were composed almost entirely of oocysts. When shed, they sank to the bottom and looked somewhat like "spent" tapeworms (Figs. 1, 2). The infected fish were very lethargic and their intestines were swollen with contained fluid. Although I believe that the Eimeria is pathogenic, a heavy infection of other parasites made this difficult to determine. These fish had apparently …

Studies On Myxosoma Cartilaginis N. Sp. (Protozoa: Myxosporidea) Of Centrarchid Fish And A Synopsis Of The Myxosoma Of North American Freshwater Fishes, Glenn L. Hoffman, Robert E. Putz, Clarence E. Dunbar

United States Fish and Wildlife Service: Publications

Myxosoma cartilaginis n. sp. is described from the cartilage of Lepomis macrochirus (bluegill), L. cyanellus (green sunfish) and Micropterus salmoides (largemouth black bass).  The development of the parasite is described from naturally infected fish which were held in spore-free water after infection.  The sporoplasm invades cartilage, and becomes a multinucleate trophozoite which forms pansporoblasts, each of which produces 2 to 4 spores.  The first spores appear in 7 weeks.

The histopathology in the above fish consists at first of little cellular reaction, but after 4 to 5 months epithelioid granulomas appear arround some of the spore masses.  Cartilage liquefaction is …
