The Occurrence Of Lymphocystis In Micropogon Undulatus And Cynoscion Arenarius From Mississippi Estuaries, J.Y. Christmas, H.D. Howse

Gulf and Caribbean Research

Lymphocystis was observed in Atlantic croakers (Micropogon undulatus) and sand seatrouts (Cynoscion arenarius) collected from brackish waters of the Mississippi Gulf Coast. This is the first report of lymphocystis in Fishes of the Gulf of Mexico and adds one family and two species to host records.

Microscopic examination of the tumors revealed several histologic differences in the lesions of the two species. Mature tumor cells in the croakers were larger than those in the sand seatrout. In the croakers, these cells were closely packed and their hyaline capsules were usually confluent. In the sand seatrouts, the …

An Investigation Of The Fish Population Within The Inland Waters Of Horn Island, Mississippi, A Barrier Island In The Northern Gulf Of Mexico, James S. Franks

Gulf and Caribbean Research

An investigation to ascertain the species composition and the relative abundance of the fish population within the inland waters of Horn Island, Mississippi, a member of the offshore barrier island chain, was made from August 1965 to September 1966, and 69 species representing 58 genera and 35 families were encountered. In respect to the fishes certain biological and physical factors were noted.

Forty-nine collecting stations were established on the island, and these were categorized according to the nature of their appearance and location. A salinity range from fresh to 29.9 ppt. was recorded for the sampled bodies of water, with …

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 …

The Functional Morphology And Ecology Of Chone Mollis, Dale Brian Bonar

University of the Pacific Theses and Dissertations

Chone mollis occurs in large numbers in Tomales Bay and is an ecologically important infaunal member of the bay community. As with most marine communities, very little work has been done with individual species of the community. The present study of C. mollis is a contribution towards an understanding of the community as an ecological unit.

This study investigates the structure and function of the tube; tube-building habits; burrowing and locomotion; external anatomy; feeding; and internal anatomy of the muscular, skeletal, vascular, excretory, reproductive, and alimentary systems of C. mollis.

Embryogenesis, Histology, And Organology Of The Ovary Of Brevoortia Patronus, Ralph M. Combs

Gulf and Caribbean Research

One hundred ninety-one large scale menhaden, Brevoortia patronus, ranging in age from larvae to sexually mature females were used in this study. Collections were made in the littoral and shallow off shore waters of the Gulf of Mexico from Dauphin Island, Alabama, westward to West Bay, Louisiana, at intervals throughout a five year period. Using standard paraffin techniques a number of staining methods were employed. Cytological and histological accounts are presented of the tissue elements of the gonads beginning with inception in the larvae, sexual differentiation to the sexes, and the cyclic changes associated with oogenesis and spawning in …

A Discussion Of The Cytherinae (Ostracoda) With Description Of Two New Species, Leslie Edward Watling

University of the Pacific Theses and Dissertations

This paper is concerned with the description of two new ostracod species, and the discussion of their affinities with other species in the subfamily Cytherinae. In this discussion reference is made to the morphological features of several genera. At this point it must be made clear that although the original type descriptions were used, the author has never seen the type specimens. Thus, all discussion is based on these original descriptions as well as on available supplementary material.

A Study Of Syngnathus Scovelli In Fresh Waters Of Louisiana And Salt Waters Of Mississippi, Edward Caldwell Whatley

Gulf and Caribbean Research

A breeding population of Syngnathus scovelli was discovered in 1960 in Lake St. John near Ferriday, Louisiana, which is over 300 river miles from the Gulf of Mexico by the shortest possible route. Although S. scovelli has been known to be euryhaline, this constitutes the first record of a breeding population in fresh water.

This study encompassed the period from July 1960 through February 1966. During this time S. scovelli were maintained for varying periods of time in fresh water aquaria. The longest period of time any one specimen lived in captivity was from 29 September 1960 until 16 November …

Marine Fungi Of Iceland: A Preliminary Account Of Ascomycetes, A. R. Cavaliere

Biology Faculty Publications

This paper reports, for the first time, 25 species of marine pyrenomycetes from Icelandic waters. Taxonomic notes are included for certain species.

Surtsey, a submarine volcanic upthrust off the south coast of Iceland (Thorarinsson, 1967), is a current center for cooperative geophysical, geochemical, and biological investigations on an international scale. The mycological portion of the total biological research effort of the Surtsey project has emphasized a survey of the marine and freshwater mycoflora on the mainland of Iceland itself as a necessary prerequisite to ecological studies on Surtsey. With the exception of two reports on aquatic phycomycetes (Larsen, 1931, and …

A Commensal Relationship Between A Foraminifer And A Bivalve Mollusk, Wayne D. Bock, Donald R. Moore

Gulf and Caribbean Research

During June, 1960, the M/V Hermes of the Gulf Coast Research Laboratory made several trawl hauls south of Horn Island, Mississippi. One haul was made June 27 at a depth of 20 m. on sandy mud botton at 30°04’30” N., 88”36’ W., or about 10 nautical miles south of Horn Island. A considerable number of animals, including starfish, hermit crabs and tube worms, were caught in the trawl. Pieces of the parchment-like worm tube of Chaetopterus variopedatus (Renier) were caught in the meshes of the net and were also collected.

A small bivalve mollusk, Notocorbula operculata (Philippi 1848) was found …

A Supplement To The Fauna And Flora Of Horn Island, Mississippi, E. Avery Richmond

Gulf and Caribbean Research

Since the publication of “The Fauna and Flora of Horn Island, Mississippi’’ (Richmond 1962) search for unrecorded species present on this island, or in the waters surrounding it, has been continuing by myself and others. The premise that all of the plants and animals living in a given area can never be located completely is naturally well-founded. However, it seems advisable to continue the search for unlisted species of Horn Island.

Many unrecorded specimens have been collected and it seems proper at this time to make a supplementary list available to the public, particularly those interested in fields of science …

The Status Of Seals In The Gulf Of Mexico With A Record Of Feral Otariid Seals Off The United States Gulf Coast, Gordon Gunter

Gulf and Caribbean Research

The only seal native to the Gulf of Mexico and the Caribbean area is the West Indian seal (family Phocidae). It is tan on the upper surface and a yellowish white underneath. It is now extinct or nearly so. Two seals were reported in Louisiana near the mouth of the Mississippi in January 1966. Photographs of one animal taken from a helicopter showed an otariid seal. In late June a light colored otariid seal began to reside on the buoys of the ship channel leading into Mobile Bay. It stayed there about two and a half weeks. The animal was …

Observations On The Stone Crab, Menippe Mercenaria Say, In The Vicinity Of Port Aransas, Texas, Earnest H. Powell Jr., Gordon Gunter

Gulf and Caribbean Research

Observations on the stone crab, Menippe mercenaria Say, were started on December 16, 1947. The purpose of these observations was to study the natural history and behavior of this crab, with special reference to its importance as an oyster predator. Plans called for some simple laboratory experimentation and monthly field observations. Although the regularity of the observations was interrupted for various reasons, some information gained which may interest workers is herewith presented.

Meristic And Morphometric Data On The Flatfish Citharichthys Gilberti From Panama, C.E. Dawson

Gulf and Caribbean Research

Citharichthys gilberti Jenkins and Evermann, a common eastern Pacific flatfish, is known from Guaymas and Baja California, Mexico, south to Peru (Miller, 1966). It attains a total length of at least 260 mm (Meek and Hildebrand, 1928), frequently occurs on muddy bottoms and may enter rivers or other brackish water environments. Despite wide distribution there are apparently few literature references to the species and little is known of its life history or development. During a recent trip to the Pacific coast of Panama, C. gilberti was found to be the most abundant flatfish taken at a number of poisoned inshore …

Digenetic Trematodes From Embiotocid Fishes Of Tomales And Bodega Bays, California, Thomas David Rodella

University of the Pacific Theses and Dissertations

The present paper deals solely with parasites of marine fishes of the family Enbiotocidae represented in the American Pacific according to Special Publications no. 2, American Fisheries Society, 1960, by 20 species, all of which are marine except the Tule perch, Hysterocarpus traski (Gibbons) from fresh water. In Tomales and Bodega Bays 174 fishes representing 9 embiotocid species were examined and found to harbor 6 species of digenetic trem todes, including one here in described as new.

Distribution Of Macroinvertebrates In The Green River Below Flaming Gorge Dam, 1963-1965, William D. Pearson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was undertaken to determine the effects of rotenone applied during a fish control operation in September 1962 and the installation of Flaming Gorge Dam in November 1962 upon the distribution of invertebrates in the Green River. Since these two events, the river has changed from a warm, turbid stream to a cold, clear trout stream for about 45 miles below the dam. Totals of 234 bottom samples and 394 drift samples were collected between the dam and Ouray, Utah (166 miles below the dam). The species composition of the fauna above Carr Ranch was much simpler during 1964-65 …

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 …

Diurnal Distribution Of Phytoplankton From A Single Station At The Mouth Of The James River, Harold G. Marshall

Biological Sciences Faculty Publications

Eight sets of water samples were taken to a depth of 36 ft. during a 24-hr. period. A homogeneity was found in the vertical distribution of the total phytoplankton in samples from 7 of the 8 hydro-casts. Skeletonema costatum and Asterionella japonica were the most numerous phytoplankters in every sample, with the majority of their counts each exceeding 500, 000 cells per liter.

A Bibliography Of Anomalies Of Fishes, Supplement 1, C.E. Dawson

Gulf and Caribbean Research

The original bibliography (Gulf Res. Repts. 1 (6), 1964) has, reportedly, been of considerable value to workers interested in the teratology of fishes and other vertebrates. The present supplement is the first of a proposed series which will attempt to include all new and pertinent publications as well as those which have previously been overlooked. The overall usefulness of the bibliography should be enhanced by its maintenance on a relatively current basis. Supplements will be issued irregularly and will normally include 75 to 100 new citations.

Oyster Abundance In Apalachicola Bay, Florida In Relation To Biotic Associations Influenced By Salinity And Other Factors, R.W. Menzel, N.C. Hulings, R.R. Hathaway

Gulf and Caribbean Research

From June 1955 through May 1957, stations on three oyster reefs were sampled quantitatively at intervals and all oysters and associated macroscopic organisms were recorded per unit area. Station I was a privately leased “natural” reef, consisting of higher places exposed at low water, with a salinity range of 22.7-36.6 o/oo and was fairly productive. Station II, depth ca. two meters, was the least saline, range 1.2-29.3 o/oo, and was considered very productive for natural reef. Station III, depth one meter, salinity range 7.5-35.7 o/oo, was depleted although there was an abundant spatfall.

Habits Of Juvenile Fishes In Two Rhode Island Estuaries, Mohammed Saeed Mulkana

Gulf and Caribbean Research

The basic purpose of this work was to gain information on the possible role of some Rhode Island estuaries as nursery grounds for young migrant and resident species of fishes.

The areas selected were, the lower Pettaquamscutt River and the lower Point Judith Pond, both in the town of Narragansett, Rhode Island. The seining operations were carried through summer and early fall of 1962 when these estuaries are heavily used as nursery grounds. Major features of the occurrence, abundance and distribution of young fishes were deduced by examining samples from seine hauls. Thirty-six species were recorded from the lower river …
