The Temporal And Spatial Distribution Of Blue Crab Larvae On The Mid-Atlantic Bight Adjacent To The Chesapeake Bay, 1982-1983, Lyle Michael Varnell

OES Theses and Dissertations

Recruitment processes are important information for the management of commercially and recreationally exploited marine species. Recruitment processes of the Chesapeake Bay's most important commercial and recreational species, the blue crab, are unknown, due in part to the lack of knowledge of the processes directly preceeding recruitment.

The present study was undertaken to investigate and explain the movement and developmental patterns of blue crab larvae while offshore. Interannual and intraseasonal variations of these patterns were also examined.

Sampling occurred from May to November during 1982 and 1983. Larvae were collected at three depths (neuston layer (upper 10 cm), one meter and …

Picoplankton/Phytoplankton Dynamics In Hampton Roads, Virginia, Leslie E. Dorworth

OES Theses and Dissertations

The biomass distribution of the three main size components of the phytoplankton (net, nano, and picoplankton) was examined in the lower Chesapeake Bay. Work was done at two stations during the spring and neap tidal cycles when freshwater flow into the bay was at its seasonal minimum and maximum. Emphasis was placed on how the picoplankton ( < 2.0 μm, > 0.2 μm) reacted during the sampling period.

Picoplankton made up approximately 13% of the total biomass, during the observed time period, at the more oceanic station. The picoplankton fraction contributed up to 16% of the total biomass at the estuarine station. From this …

Effects Of Resident Species On Recruitment Into A Community: Larval Settlement Versus Post-Settlement Mortality In The Oyster Crassostrea Virginica, Roman Zajac, Richard W. Osman, Robert B. Whitlatch

Biology and Environmental Science Faculty Publications

Laboratory and field experiments revealed that a variety of species of common, sessile invertebrates, including barnacles, ascidians, and bryozoans, affected the settlement and post-settlement abundance of the oyster Crassostrea virginica (Gmelin). While the nature of the effects varied, most species both reduced oyster settlement by covering and removing substrate available for attachment, and increased settlement on adjacent surfaces. The solitary ascidians Ciona intestinalis (L.) and Styela clava (Herdman), were found to be predators of oyster larvae. Post-settlement survivorship and growth were also strongly affected by the presence of sessile species. In most cases the effects were negative and correlated with …

Southern Demersal Gillnet And Longline Fishery., Management Advisory Committee

Fisheries Management Papers

In its report to the Ministier for Fisheries in November 1986, the Southern Western Australian Shark Working Group recommended the establishment of an Industry/Government Mangement Advisory Committee to provide managememt advice on the fishery to the Minister for Fisheries. The Advisory Committee held its first meeting in Albany on 23 February 1989. After being briefed on the state of shark stocks, the Committee's deliberations fell into three broad categories. In the first category there was sufficient time and information available to make a recommendation to the Minister for Fisheries. In the second category, discussion commenced, but was held over to …

A Review Of The Shark Bay Pearling Industry., D. A. Hancock

Fisheries Management Papers

While there are currently only two pearl culture leases in Shark Bay, two new applications for leases have already been received by the W.A. Fisheries Department. Increased interest is being generated about pearl culture in Shark Bay, which will need to be considered against the background of management plans designed to restrict further entry into other areas, notably the pearly industry of W.A from Exmouth Gulf northwards, and the pearling industry of the Northern Territory. Recent successes with pearl culture in both those areas, and the greatly increased revenues and high lease transfer values realised, must inevitably focus interest on …

Population Variation In The Mitochondrial-Dna Of Two Marine Organisms: The Hard Shell Clam Mercenaria Spp. And The Killifish, Fundulus Heteroclitus, Bonnie Lynn Brown

OES Theses and Dissertations

The two major topics are covered in this dissertation: the integration of molecular genetic tools with applied aquacultural research and short-term evolutionary dynamics. The first study investigated the extent of geographic differentiation of native clam stocks along the U.S. east and Gulf coasts. Clam mitochondrial DNA (mtDNA) demonstrated size polymorphism (16.5-19.0 kb) and restriction site heteroplasmy. Size heteroplasmic individuals occurred at a frequencies of 0-89% in clam populations. Restriction site heteroplasmy occurred in 12% of the 317 individuals assayed. Results of the study indicated that although harbouring a wealth of genetic variation, clams from northern regions were similar and lacked …

Fisheries Management Paper No.23 - Management Of The South-West Inshore Trawl Fishery., N. Moore

Fisheries Management Papers

This report outlines the management plan for the south west inshore trawl fishery which already operates in coastal waters less than 200 metres deep between Guilderton and Cape Leeuwin.

This management plan takes into account these important concerns and has specifically set aside a strip of coastal area from Cape Bouvard to Cape Leeuwin for recreational usage and for protection of the benthic community, and closed the management zone north of Burns Beach to trawling.

A Report On Marron Fishing In Western Australia., Doug Wenn

Fisheries Management Papers

The marroning experience is one enjoyed by many Western Australians. A rapid increase in fishing effort evidenced by the increase in number of recreational fishing licences issued, combined with low rainfall in the last few years resulted in a dramatic reduction of marron catch rates during 1986/87. In view of the state of marron stocks, the Minister for Fisheries considered it appropriate to close the 1987/88 marron season.

Survey And Reconnaissance Of Sea Turtles In The Northern Gulf Of Mexico, Larry Ogren

United States Department of Commerce: Staff Publications

This is a report on the results of an aerial survey of nesting beaches conducted during the period from May 16, 1977 to August 11, 1977. The area covered included the barrier beaches and offshore islands from the Florida-Alabama state line to the Rio Grande, Texas. Additional historical information is provided in order to compare current nesting activity with previous years as well as anecdotal observations on the occurrence of sea turtles in this region.

Rock Lobster Industry Advisory Committee Report To The Minister For Fisheries., Rock Lobster Industry Advisory Committee

Fisheries Management Papers

The total catch of about 12.1 million kilograms for the 1987/88 season, based on processor returns, was an increase of 44% on the 1986/87 season. This very high catch, the third highest on record, resulted from an above average perulus settlement in 1983/84 and a "flow-on" of fast growing animals stemming from the expected high recruitment in 1988/990 caught as "reds" in 1987/88.

The Committee has identified five major elements related to the state of the rock lobster fishery upon which management advice is considered.

a) The undersize fraction of the population.

b) The "whites" which provide a significant proportion …

Marine & Environmental Sciences Faculty Articles

One of the dominant amphipods in algal turf communities at Discovery Bay, Jamaica, is a new species, Gammaropsis arawakia, characterized by long peduncle of uropod 3, small coxa I, 3-articulate accessory flagellum, extremely setose gnathopod 2, one pair of dorsal teeth on urosomite I, pointed ocular lobe, and oblique upper margin of cephalic sinus for antenna 2.

Four Species Of Synopiidae From The Caribbean Region (Crustacea: Amphipoda), J. L. Barnard, James Darwin Thomas

Marine & Environmental Sciences Faculty Articles

Synopia ultramarina is redescribed from the Gulf Stream and the Florida Keys and comments are made on the tangled taxonomy in Synopia. Tiron bellairsi, originally described from Barbados, is reported from Belize, at the opposite side of the Caribbean Basin. Garosyrrhoe bigarra, a Pacific species, is also reported from Belize, but no clear subspecific differences are detected as yet between Pacific and Atlantic populations.

A New Species, Ampelisca Burkei, (Crustacea, Amphipoda) From Florida, J. L. Barnard, James Darwin Thomas

Marine & Environmental Sciences Faculty Articles

A new species Ampelisca burkei, from Florida, is described. This species appears to be very close to A. lobata Holmes, from the eastern Pacific Ocean, but differs in the shape and setation of article 4 on pereopod 7, and the presence of an anteroventral spine-seta on article 5 of pereopod 7.

Invertebrates Associated With The Thinstripe Hermit Clibanarius Vittatus (Bosc) (Crustacea: Decapoda: Diogenidae) From The Barrier Islands Of Mississippi, Leslie Bruce

Gulf and Caribbean Research

Hermit crabs, the gastropod shells that they inhabit, and associated epifauna constitute a motile microhabitat. Twenty-three macroscopic. epifaunal invertebrates were associated with the diogenid crab Clibanarius vittatus in Mississippi coastal waters. Epibiotic growth may discourage predation of the crab, reduce competition for the shells, or provide an advantage in agonistic shell interaction. In addition, the shell provides a hard substrate for settling and attachment of epifauna in an area that is largely devoid of hard substrate. Reduced sedimentation and prevention of shell burial, improved food availability, transport, and protection from predation may also be advantageous to the epizoans.

Tanaidacea (Crustacea: Peracardia) Of The Gulf Of Mexico. Viii., Barbara J. Viskup, Richard W. Heard

Gulf and Caribbean Research

Pseudosphyrapus siegi, n. sp. is described from benthic samples collected in deep water (595-2400 m) from the northern Gulf of Mexico. Of the five currently recognized species of Pseudosphyrapus Cup, 1980, P. siegi is most closely related to P. dispar (Lang, 1968), a southwestem Pacific cognate and only other member of the genus having a squama on antenna 2. Pseudosphyrapus siegi is distinguished from P. dispar by: (1) a more triangular, but less acute, rostrum (2) the presence of two 4-pronged spines on the second maxilla (homologous spines on P. dispar are 3-pronged), and (3) the absence of a …

Tanaidacea (Crustacea: Peracardia) Of The Gulf Of Mexico. Vii. Atlantapseudes Lindae, N. Sp. (Apseudidae) From The Continental Slope Of The Northern Gulf Of Mexico, Gabriele H. Meyer, Richard W. Heard

Gulf and Caribbean Research

During 1983 through 1985, 53 specimens of Atlantapseudes lindae, new species, were collected in box core samples taken on the continental slope in the northern Gulf of Mexico. Atlantapseudes lindae can be distinguished from the only other member of the genus, A. nigrichela Băcescu, 1978 by several characters, including the length of the squama of antenna 2, which is no longer than the third peduncular segment, and the absence of anterolateral spines on pereonites 1-2 of females and 1-6 on males. The diagnosis for genus Atlantapseudes Băcescu, 1978 is amended to include the presence of sexually dimorphic chelae and …
