Larval Cestode Parasites Of Edible Mollusks Of The Northeastern Gulf Of Mexico, Edwin W. Cake Jr.

Gulf and Caribbean Research

Ten distinct species of larval cestodes were obtained from 43 edible, or potentially edible, benthic mollusks of the northeastern Gulf of Mexico. Three of the infected mollusks, American oysters, Crassostrea virginica (Gmelin), Atlantic bay scallops, Argopecten irradians concentricus (Say), and sunray venus clams, Macrocallista nimbosa (Lightfoot), are important commercial species in the eastern Gulf and the remainder are occasionally eaten by epicurean shellfishermen or were consumed by prehistoric, aboriginal Indians of the Gulf coast. The cestodes represent four orders, seven families and nine recogized genera and include the trypanorhynchs, Euteirarhynchus sp. (of Cake 1975) and Parachristianella sp. (of Cake 1975), …

The Effect Of Depth On Survival And Growth Of Oysters In Suspension Culture From A Petroleum Platform Off The Texas Coast, John Ogle, Sammy M. Ray, W.J. Wardle

Gulf and Caribbean Research

The effect of depth on oysters in suspension culture from a petroleum platform off the Texas coast was monitored for 20 months. Growth and condition was similar for adult oysters cultured at five levels down to 8 m. Oysters had a growth rate of 1.2 mm (level 3) to 1.4 mm (level 1) per month,representing an increase in length of 94% to 150% for the 20 months. The condition was best in June 1973 after five months placement offshore (condition index of 14.8, 15.5, 14.7, 13.5 and 13.2 for levels 1 through 5, respectively). The condition was lowest in June …

Notes On Stenopus Scutellatus And S. Hispidus (Decapoda, Stenopodidae) From Mississippi, Ron Lukens

Gulf and Caribbean Research

Two species of Stenopus were collected in 1976 from a Liberty ship artificial reef near Horn Island, Mississippi. Six specimens of S. scutellatus were collected. This represents an occurrence record for Mississippi. Five specimens of S. hispidus were also collected; thus, extending the range in the Gulf of Mexico by about 400 krn to the northwest.

Ultrastructure Of Lymphocystis In The Heart Of The Silver Perch, Bairdiella Chrysura (Lacépède), Including Observations On Normal Heart Structure, Harold D. Howse, Adrian R. Lawler, William E. Hawkins, Carolyn A. Foster

Gulf and Caribbean Research

The fine structure of normal heart muscle from the silver perch, Bairdiella chrysura (Lacépède), is similar to that previously reported for marine and freshwater teleosts.

Cardiac lymphocystis is a viral disease manifested by single, giant-cell lesions variously located in the epicardium, trabecular spaces, and subendocardium – in direct apposition to myocardial cells. Occasionally, the hyaline capsule of lymphocystis cells partially surround myocardial cells but cause no pathological changes or inflammatory reaction.

The lymphocystis cells contain typical cellular organelles, including the viroplasmic net unique to these cells. Annulate lamellae, often continuous with the rough endoplasmic reticulum, are present, usually along the …

The Eye Lens Weight Technique In Aging Of The Atlantic Croaker, Micropogon Undulatus, Constantine E. Mericas

Gulf and Caribbean Research

The eye lens weight to age relationship was examined in croaker, Micropogon undulatus. Lenses were removed, fixed, and weighed using standard techniques. Age estimates were assigned based on total length measurements. Lens weight showed good correlation with total length. Age could be estimated by eye lens weight, but no more accurately or precisely than with length frequency analysis. Cumulative percent frequency analysis of lens weights showed distinct inflections in the curve, which correspond to hypothesized length at age points. The data seem to verify age structure based on length frequency analysis.

Location Of The Mississippi Sound Oyster Reefs As Related To Salinity Of Bottom Waters During 1973-1975, Charles K. Eleuterius

Gulf and Caribbean Research

The relationship of producing natural oyster reefs of Mississippi Sound to the salinity regime of bottom waters is investigated. Extreme and average conditions were extracted from data taken at 87 stations over a 21-month period from June 1973 through February 1975. With one exception, the producing reefs were subjected to salinity minimums of 2.0 to 4.0 parts per thousand (ppt), maximums of 18.0 to 22.0 ppt, with average conditions being between 10.0 and 16.0 ppt. Salinity-suitable areas in the Sound not now inhabited by oysters are described.

Occurrence Of The Brackish Water Asellote Isopod Munna (Uromunna) Reynoldsi In Texas, Betty J. Callahan, Scott T. Clark, Philip B. Robertson

Gulf and Caribbean Research

The asellote isopod Munna (Uromunna) reynoldsi Frankenberg and Menzies, previously known from coastal swamps a t Sapelo Island, Georgia, is reported from Texas. Several specimens were collected in grab samples from Fence Lake, a small brackish marsh lake (salinity 0 to 2.7 ppt) in Sca Rim State Park, and in a nearby coastal marsh (salinity 4.4 ppt). The present records indicate that the species is a brackish water form.

Notes On The Status Of The Gannet (Morus Bassanus) In The Gulf Of Mexico, With A Record From Mississippi, Gordon Gunter, W. David Burke

Gulf and Caribbean Research

The Northern Gannet nests on rock cliffs in the north Atlantic and winters as far south as Yucatan on the west, and N.W. Africa on the east. The birds are not known to cross land and seem to fly around Florida to enter the Gulf of Mexico. Most numbers have been reported off Louisiana, Mississippi, Alabama and the Florida panhandle. Numbers in the western Gulf seem to be few. There are 12 skeletal parts or skins of Texas gannets in museums in Texas and Louisiana. Two specimens have been collected in Louisiana, only one of which is known to remain. …

Calcification And Productivity In A Dominant Shallow Water Reef Building Coral, Acropora Palmata (Lamarck), Elizabeth H. Gladfelter

University of the Pacific Theses and Dissertations

Coral reefs are "constructional physiographic features of tropical seas consisting fundamentally of a rigid calcareous framework made up mainly of the interlocked and encrusting skeletons of reef-building (hermatypic) corals (Wells,1957). The principal organisms responsible for the construction of modern day coral reefs, the stony corals, comprise the cnidarian order Scleractinia, which is closely allied to the sea anemones (Actinaria). Individual polyps secrete a calcium carbonate skeletal cup (calyx) beneath the basal epidermis. In most coral species the polyps remain connected by living tissue forming a colony and calcium carbonate is deposited beneath the basal epidermis of the entire colony, thereby …

A Comparative Study Of A Salt Water Impoundment With Its Adjacent Tidal Creek Pertinent To Culture Of Crassostrea Virginica (Gmelin), William D. Anderson Iii

OES Theses and Dissertations

Certain physical, chemical and biological characteristics associated with the culture of subtidal Crassostrea virginica were assessed in a salt water impoundment and its adjacent tidal feeder creek. Large seed oysters (initial y = 57.3 mm) were transferred from a somewhat polluted estuary of Charleston Harbor to floating, mid-water, and bottom hardware cloth trays (200/tray) in a four hectare pond. Identical trays at comparable depths were placed in the tidal creek and each location was sampled monthly for growth and survival. Surface and bottom water samples were collected weekly throughout the study and hourly during four seasonal 25 hour stations. Standard …

An Intensive Study Of The Spring Phytoplankton Bloom In Lynnhaven Bay, Virginia, Donald Lynn Webster

Biological Sciences Theses & Dissertations

Phytoplankton samples were collected biweekly from two stations, one in each branch of Lynnhaven Bay, Virginia over the period January 24 to June 9, 1975. Water temperature, salinity, pH, oxygen, ammonia, urea, reactive nitrite, reactive nitrate, reactive phosphorus, productivity, transparency, and weather conditions were recorded concurrently. Data were manipulated employing analysis of variance, simple correlation, correlation matrices, and forward stepwise multiple regression. Total phytoplankton numbers exhibited a unimodal pattern. A pre-bloom pulse was recorded at both stations in late February. The spring bloom lasted from April through May. Phytoplankton growth was primarily a function of nutrient supply and temperature. Nutrient …

Parasites Of California Marine And Estuarine Fish, Milton S. Love, Mike Moser

Harold W. Manter Laboratory of Parasitology: Faculty Publications

While working on the parasites of several California marine fish, it was difficult to find out which parasites had been reported from our fish. Pertinent sources were scattered over a number of journals, covering many years. We compiled this list because we felt there was a need for a single source which would give all the parasites infecting California marine fish. As "marine fish" was a somewhat vague term, we decided to use it in a broad sense and included estuarine and anadromous fish in the survey. In addition, we have included records from landlocked populations of anadromous fish, such …

The Distribution Of Submersed Hydrophytes In Currituck Sound, Steven Harry Davis

Biological Sciences Theses & Dissertations

The rooted submergent flora of Currituck Sound, North Carolina was determined, and the distributions of its species investigated with respect to salinity, substrate texture, depth, pH, turbidity and species co-occurrence. Eight species of hydrophytes were found: Potamogeton pectinatus, Fotamogeton perfoliatus, Ruppia maritima, Zannichellia palustris, Najas guadalupensis, Elodea nuttallii, Vallisneria americana, and Myriophyllum spicatum. The mean salinities at which each species occurred ranged from 1.0 ppt for E. nuttallii to 3.1 ppt for Z. palustris, Ruppia maritima, Z palustris and V. americana were the only species that commonly occurred on coarse-grained substrates. Elodea nuttallii and N. guadalupensis …

Test Variation In The Sand Dollar, Mellita Quinquiesperforata (Leske), George Glynn Rountree

OES Theses and Dissertations

Mellita quinguiesperforata is a common member of the benthos along the eastern coast of North America. This study considers variation of the test within the species, specifically: 1) variation in test weight, 2) variation in the length-width relationship, and 3) the average number of pore pairs in the ambulacral petals.

A total of 844 sand dollars from three localities was utilized: 1) Pass-a-Grill Beach, St. Petersburg, Florida,2) Bird Shoal, Beaufort, North Carolina, and 3) Fisherman Island, Virginia.

Animals were measured for length and width and the dry weight determined. Prediction equations for the size-weight relat1onships were computed for the three …

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 …
