Cetacean Notes. I. Sei And Rorqual Whales On The Mississippi Coast, A Correction. Ii. A Dwarf Sperm Whale In Mississippi Sound And Its Helminth Parasites, Gordon Gunter, Robin Overstreet

Gulf and Caribbean Research

I. Gunter and Christmas (1973) described the events leading to the stranding of a baleen whale on Ship Island, Mississippi, in 1968, giving the species as Balaenoptera physalus, the Rorqual. Unfortunately the identification was in error, but fortunately good photographs were shown. The underside of the tail was a splotched white, but there was no black margin. The specimen also had fewer throat and belly grooves than the Rorqual, as a comparison with True’s (1904) photograph shows. Dr. James Mead (in litt.) pointed out that the animal was a Sei Whale, Balaenoptera borealis. This remains a …

Effect Of Thermal Stress On Larvae Of Patiria Miniata (Brandt) Including Studies On Induction Of Spawning, Development And Larval Tagging, Kenneth A. Simon

University of the Pacific Theses and Dissertations

It has been estimated by the Department of the Interior that by 1985 nearly one-quarter of all surface water in the United States will be used in removal of waste heat produced in electric generation. This will involve subjecting tremendous quantities of plankton to rapid fluctuations in temperature. The biological effect of such treatment on primary productivity and composition of zooplankton populations is not fully understood. To date little published information is available on the effect of rapid temperature fluctuations on plankton. Such temperatures are the result of heat exchange found in the cooling system of a steam-generating electric station. …

Population Ecology Of The Littoral Fringe Gastropod Littorina Planaxis In Northern California, Russell James Schmitt

University of the Pacific Theses and Dissertations

Life history patterns of individual organisms are the result of natural selection and should be correlated with particular physical and biological characteristics of habitats in which they live. The littoral fringe is known to be the most severe physical habitat in the intertidal zone, and it is expected that organisms in it should have population characteristics associated with selective response to physical adversity rather than biological interaction. Ecological studies of populations of Littorina planaxis were made in the Dillon Beach and Bodega Head areas. The study localities differed principally in extent of wave exposure rather than geographical location.

Protozoan Symbionts From The Anemone Bunodosoma Cavernata From Galveston Island, Texas, Philip J. Phillips

Gulf and Caribbean Research

The anemone Bunodosoma cavernata is a common inhabitant of the Texas coast and cursory observation revealed a large complement of protozoan associates. These included Saprodinium, Euplotes, Paraeuplotes, Vorticella, Cohnilembus, Anophrys, Uronema and Vahlkampfia.

Approximately forty anemones were collected from jetty rocks on Galveston Island on 3 November 1970. Note was made within one day of protozoans found on the external surfaces, in the coelenteron and in surrounding sea water. The anemones were kept until 7 December 1970 under varying conditions and bi-weekly note was made of the associated protozoan fauna.

Some Analyses Of Twentieth Century Landing Statistics Of Marine Shrimp Of The South Atlantic And Gulf States Of The United States, Gordon Gunter, Katherine Mcgraw

Gulf and Caribbean Research

There is a strong correlation between the total catch of white and brown shrimp with dockside prices on the United States Gulf Coast since 1902, but there is no significant correlation between South Atlantic production and prices, probably because the South Atlantic shrimp stocks have been over-fished since the 1920s. There is no negative or positive correlation between the catch statistics of brown and white shrimp of the United States, and these species seem to be weakly competitive, if at all. There is a significant correlation between the annual production of South Atlantic and Gulf white shrimp, but there is …

An Examination Of Legislation For The Protection Of The Wetlands Of The Atlantic And Gulf Coast States, Anthony J. Haueisen

Gulf and Caribbean Research

The most useful aquatic areas in the world are in serious danger of destruction. The estuaries, where fresh water, land and sea meet in a dynamic and highly productive zone, are today gravely threatened through unwise and unplanned excessive use of their valuable but finite capacities. Estuaries include the coastal zone which is affected by both the run-off of fresh water from the land and the salt water from the sea. This zone includes tidal rivers, marshes, bays and river mouths. The value of these estuarine regions has been well established by biologists. However, this value is fully appreciated by …

A Geochemical Study Of A Marsh Environment, Thomas F. Lytle, Julia Sever Lytle, Patrick L. Parker

Gulf and Caribbean Research

The goal of this study was twofold: 1) chemically to characterize a specific salt marsh, the sediments and associated biota and 2) to establish clear relationships between the chemical substances residing in the sediments and similar or identical substances occurring in the biological specimens. In this particular study it was felt that the hydrocarbons would yield the most significant organic geochemical information. These compounds are ubiquitous but minor components of all organisms. Though their function is not entirely understood, it is known that they are concentrated in the waxy coatings of plants and most likely aid in the protective mechanisms …

A Study On The Growth Rate Of Brown Shrimp (Penaeus Aztecus Aztecus Ives, 1891) From The Coasts Of Veracruz And Tamaulipas, Mexico, Ernesto A. Chávez

Gulf and Caribbean Research

The present study was undertaken with the purpose of getting the proper basis for exploiting brown shrimp resources in a rational manner, by introducing control regulations of fishing activities. The growth rate models are necessary for the other parameters of population dynamics of the stocks of this species, whose annual catch, Osborn, Maghan and Drummond (1969), averages 54 million pounds of tail weight, representing 52% of the total shrimp caught in the Gulf of Mexico. This shows that Penaeus aztecus aztecus is the most important of shrimp species exploited in this region. Nevertheless, the brown shrimp is the least well …

Critical Flicker Frequency In A Harp Seal, Pagophilus Groenlandicus (Erxleben, 1777), Charles D. Bernholz

University of Nebraska-Lincoln Libraries: Faculty Publications

Critical flicker frequency (CFF) in a free-swimming harp seal (Pagophilus groenlandicus) was investigated using behavioral techniques. The resulting CFF versus intensity contour indicates a definite rod-cone break, confirming a duplex photoreceptor population whose presence had not been observed in previous morphological reports.

The Occurrence Of The Remarkable Scyphozoan, Deepstaria Enigmatica, In The Gulf Of Mexico And Some Observations On Cnidarian Symbionts, Philip J. Phillips

Gulf and Caribbean Research

On 8 July 1965 one damaged specimen of the remarkable scyphozoan, Deepstaria enigmatica Russell 1967, was taken in the course of a sampling program conducted by the Department of Oceanography, Texas A&M University in a ten-foot Issacs-Kidd midwater trawl in the Yucatan Basin. The trawl was put into water at Lat. 19" 58' N, Long. 85" 14' W. This is the first report of Deepstaria in the Atlantic region. This medusa is otherwise known only from the Pacific Ocean where it has been captured by slurp gun from the submersible Deepstar over the San Diego Trench and has been taken …

Stranding Records Of A Finback Whale, Balaenoptera Physalus, From Mississippi And The Goose-Beaked Whale, Ziphius Cavirostris, From Louisiana, Gordon Gunter, J.Y. Christmas

Gulf and Caribbean Research

Stranding records are sometimes the only source of data concerning some species of cetaceans and it is appropriate that these incidents be reported in some detail. This is particularly true of rare or little known species. Bottle-nosed dolphin (Tursiops truncatus) carcasses stranded on the Mississippi and Louisiana coasts are so common that they receive little attention. Other species occur and have, no doubt, been overlooked or confused by laymen with Tursiops. Even the rare stranding of large whales in this area may go unreported except for news stories that fail to identify the animal properly and which …

Statistical Analysis Of A Seining Survey, James Kent Dias

MUSC Theses and Dissertations

The surf zone at Folly Beach, South Carolina was seined on a biweekly basis for two years (October 1969 through October 1971). A total of 5,517 specimens of fish and one invertebrate species (Arenaeus cribrarius) representing 20 families, 33 genera, and 42 species were collected. The five most important species collected in the surf were Menidia menidia, Arenaeus cribrarius, Trachinotus carolinus, Menticrrhus littoralis, and Anchoa mitchilli. A computer based information system was used to generate the necessary reports and summary statistics. Stepwise multiple regression techniques were used to relate occurrence of the five important surf species to selected physical parameters. …
