A Bibliography Of Anomalies Of Fishes, Supplement 2, C.E. Dawson

Gulf and Caribbean Research

This listing adds 213 titles to the original bibliography (Gulf Res. Repts. 1 (6), 1964) and the 1966 supplement (Gulf Res. Repts. 2(2) :169-176). Although a number of previously overlooked references are included, there are 137 citations of works published during the 1965-70 period. The frequency of recent publications offers some indication of the current worldwide interest in problems of fish teratology.

Descriptions Of Shrimp Larvae (Family Penaeidae) Off The Mississippi Coast, Chebium B. Subrahmanyam

Gulf and Caribbean Research

Müller (1864) showed that the penaeid egg hatches into a nauplius. Some years later studies of the metamorphosis of penaeid shrimps in the Gulf of Mexico were made (Pearson 1939, Heegaard 1953, Dobkin 1961, Cook and Murphy 1965, and Renfro and Cook 1963). The present paper treats the larvae taken in Mississippi and brings together the descriptions of the larvae scattered in the literature. The salient features of various stages of different species of the six genera studied are pointed out with the aid of drawings to facilitate easier identification. Besides the references cited above, the works of Heldt (1938), …

Notes On Insect Occurrences On The Mississippi Gulf Coast And Offshore Islands, Bryant Mather

Gulf and Caribbean Research

Dr. Gordon Gunter (1970) has written that, through the work of Dr. E. A. Richmond, “. . . The species of living organisms of Horn Island are better recorded than those of any large island on the South Atlantic and Gulf Coast.” It is to be hoped that Dr. Richmond’s work will inspire others to contribute much more to the knowledge of the fauna and flora of the Gulf Coast and its offshore islands. I give here a few notes to place some of Dr. Richmond’s work in context, to recognize work by others, and to indicate the paucity of …

Some Effects Of Hurricanes On The Terrestrial Biota, With Special Reference To Camille, Gordon Gunter, Lionel N. Eleuterius

Gulf and Caribbean Research

There have been very few articles concerning the effects of hurricanes upon marine and shore organisms. Some effects on fishes have been described by Hubbs (1962) and in that paper he reviewed some of the previous references.

Information on animals killed or injured by hurricanes is scarce because potential observers in areas where they strike are generally more concerned with practical personal matters than biological studies right after a bad storm. The senior author has been in or very close to seven West India hurricanes as they came ashore. Each time he was somewhat forewarned and had determined to make …

The Relative Abundance And Distribution Of Penaeid Shrimp Larvae Off The Mississippi Coast, Chebium B. Subrahmanyam

Gulf and Caribbean Research

The objectives of the present investigation are: (a) to delineate spawning seasons and the areas of as many species as possible based on larval abundance; (b) to study the spatial and seasonal distribution of penaeid larvae in relation to depth, temperature, salinity and seasons, which will indicate the movements of the spawners; (e) to inquire whether any correlation exists between occurrence of larvae and of adults in any area; (d) to examine the relationship between Penaeus postlarval abundance in the Mississippi Sound and larval and postlarval occurrence in the open sea; and (e) to study the vertical seasonal distribution of …

Recent Changes In The Louisiana Marsh Near Vermilion Bay, Lionel N. Eleuterius

Gulf and Caribbean Research

A special interest in marsh ecology led to the present study. Permanent sampling stations, whereby long range changes can be observed, have been neglected by researchers and there is only one known in the Gulf Coastal marshes. The uniqueness of the permanent transect offered an opportunity to study the floristic changes, if any, which occurred over a period of 18 years. Notes on the topography and other influencing factors were taken, as well as general observations on the surrounding marsh areas.

Observations On The Biology Of Mudshrimps Of The Genus Callianassa (Anomura: Thalassinidea) In Mississippi Sound, Philip J. Phillips

Gulf and Caribbean Research

The apparent habitat isolation of the mudshrimps Callianassa islagrande Schmitt and Callianassa jamaicense louisianensis Schmitt (Anomura : Thalassinidea) in Mississippi Sound is a function of species-related differences in ability to burrow and survive in the significantly different substrates of each habitat. C. islagrande is found only in sand bottomed beaches of the offshore barrier islands, whereas C. j. louisianensis is found only in the muddy backwaters of the mainland and Deer Island. Both forms produce deep and extensive permanent or semipermanent burrows in their respective habitat and are probably of some significance in sediment turnover. Laboratory studies show that C. …

Survival Of The Oyster Crassostrea Virginica (Gmelin) In The Laboratory Under The Effects Of Oil Drilling Fluids Spilled In The Laguna De Tamiahua, Mexico, Jorge Cabrera

Gulf and Caribbean Research

In 1965, 970.12 m³ of oil drilling fluid were spilled in the Laguna de Tamiahua, Mexico. Laboratory experiments were carried out to determine possible effects of this upon the oyster Crassostrea virginica. It was found that drilling fluid reduced the survival of oysters to a significant degree in concentrations above 200 ppm. At turbidities between 200 and 500 ppm, there was 50% survival on the seventh day. Tanino in concentrations between 90 and 170 ppm had a drastic effect upon survival which was 50% between the fourth and fifth days. Bentonita in 110 to 190 ppm resulted in …

Discovery Of The Carolina Marsh Clam, Polymesoda Caroliniana (Bosc), A Supposed Florida Disjunct Species, In Everglades National Park, Florida, D.C. Tabb, D.R. Moore

Gulf and Caribbean Research

The presence of disjunct species of animals on either side of the Florida peninsula has been reported by a number of authors. The littorinid mollusk, Littorina irrorata Say, which has a range from Massachusetts to the Rio Grande of Texas, except for south Florida, is one such species (Bequaert 1943). The marsh crab, Sesarma cinereum (Bosc), is another example of an animal with a distribution from Virginia to the western Gulf of Campeche except for a break in southern Florida (Rathbun, 1918). Williams (1965) lists 23 species of crustaceans having interrupted distribution at the Florida peninsula. This report on discovery …
