Description, Distribution, And Abundance Of The Blue Crab, Callinectes Sapidus (Rathbun), Spawning Stock Of The Lower Chesapeake Bay, Patrick John Geer
Description, Distribution, And Abundance Of The Blue Crab, Callinectes Sapidus (Rathbun), Spawning Stock Of The Lower Chesapeake Bay, Patrick John Geer
OES Theses and Dissertations
The lower Chesapeake Bay spawning stock of the blue crab, Callinectes sapidus, (Rathbun), is examined for seven years (1986 - 1992) in an attempt to better understand stock behavior. Three methods of post-stratification are used to describe the distribution and movement of the population over time. The three methods, density strata, geographic zones, and depth strata, did well in explaining movements of the population, indicating a trend of increased concentration of blue crabs near the eastern Bay late in the spawning season - October. The data suggest a bimodal period of spawning and a trimodal period of abundance. The …
Age And Growth Of Larval And Juvenile Atlantic Croaker, Micropogonias Undulatus, From The Middle Atlantic Bight And Estuarine Waters Of Virginia, Stephen W. Nixon
Age And Growth Of Larval And Juvenile Atlantic Croaker, Micropogonias Undulatus, From The Middle Atlantic Bight And Estuarine Waters Of Virginia, Stephen W. Nixon
Biological Sciences Theses & Dissertations
Sagittal otoliths were used to determine the age and growth of 605 larval and juvenile Atlantic croaker, Micropogonias undulatus, collected in the Middle Atlantic Bight (MAB) and estuarine waters of Virginia. A Laird-Gompertz model (r2 = 0.95) was used to describe the growth of croaker up to 65 mm standard length (SL) and 142 days (t): S1(t) = 2.657 Exp {4.656 [1-Exp (-0.008lt)]}; SL(t) = standard length at day t. Generally, croaker collected inshore were larger and older than those collected offshore, indicating estuarine immigration from offshore spawning grounds. Back-calculated hatch-dates indicated spawning over an 8- month period …
The Role Played By Semisubmersible Exploratory Drilling Platforms As A Vector In Marine Biological Introductions, Sean S. Bercaw
The Role Played By Semisubmersible Exploratory Drilling Platforms As A Vector In Marine Biological Introductions, Sean S. Bercaw
Theses and Major Papers
Through discussion of Semisubmersible Exploratory Drilling Platforms and their role as vectors in marine biological introductions, this paper establishes a base of knowledge for future referral. Included in this project are details of semisubmersibles, their unique characteristics and operations, historical movements, past introductions, future operations, and continuing potential for invasions. The significance of semisubmersibles as biological vectors is further addressed. Three criteria will be used to assess the significance of the role of semisubmersibles in the introduction of alien species: first, what is the rate of SEDP movements over time; second, how are SEDP movements unique, and what role does …
Conflicts In Use: The Impacts Of The Oil And Gas Industry On The Herring Fishery In The North Sea, Cornelia Ann Pasche
Conflicts In Use: The Impacts Of The Oil And Gas Industry On The Herring Fishery In The North Sea, Cornelia Ann Pasche
Theses and Major Papers
The interaction of the herring (Clupea harengus) with the oil and gas industry in the North Sea is reviewed. The population crash of the herring in the early 1970's and the subsequent closing of that important fishery between 1977 and 1983 has drawn considerable attention to the influences, both biotic and abiotic, affecting the recruitment to the North Sea stock. Current accepted theory points to a change in oceanic current and the subsequent decrease in salinity in the North Sea region, resulting in a change in plankton availability for larval herring as the cause of the recruitment failure during the …
Linking Management And Markets: The Northwest Atlantic Sea Herring Industry And The Case For "Regional" Quotas, Peter Jessup Moore
Linking Management And Markets: The Northwest Atlantic Sea Herring Industry And The Case For "Regional" Quotas, Peter Jessup Moore
Theses and Major Papers
This review and characterization of the U.S. Atlantic sea herring fishery and industry analyzes opportunities for and constraints to developing the herring resource more fully. Chapter 1 describes the herring resource, the existing fishery, and reviews current research into the international transboundary migrations of the Atlantic sea herring. Chapters 2 and 3 describe the development of the herring fishery management plan in the context of the global herring market and the management complications that arise from the transboundary migrations of the stocks. Examples of successful linkages between fisheries management and market development are described in Chapter 4 to illustrate the …
Reproductive Biology Of The Bowfin, Amia Calva Linnaeus, From The Green Bottom Wildlife Management Area, Cabell County, West Virginia, Katie Lee Mcginn Daniels
Reproductive Biology Of The Bowfin, Amia Calva Linnaeus, From The Green Bottom Wildlife Management Area, Cabell County, West Virginia, Katie Lee Mcginn Daniels
Theses, Dissertations and Capstones
The bowfin, Amia calva Linnaeus, is the only extant species of the family Amiidae. The Green Bottom Wildlife Management Area (GBWMA) is the home of the only known reproducing bowfin population in the state of West Virginia. The GBWMA (38°35' 35" N, 82°14' 55" W) is located along the Ohio River 26 km northeast of Huntington, West Virginia. The area (ca. 364 ha) contains a valuable wetland habitat (ca. 57 ha) in the southwestern portion of the state. A study of the reproductive biology of the bowfin became important when the u.s. Army Corps of Engineers proposed a habitat modification …
Aspects Of The Ecology Of The Wood Turtle, Clemmys Insculpta (Leconte), In West Virginia, Allan J. Niederberger
Aspects Of The Ecology Of The Wood Turtle, Clemmys Insculpta (Leconte), In West Virginia, Allan J. Niederberger
Theses, Dissertations and Capstones
An ecological study of the wood turtle, Clemmys insculpta (LeConte), was conducted in West Virginia from May 1991 to March 1993. Population structure at the primary study area (WV #1) was estimated to be 46% juvenile (H-8 yrs. old), 26% female and 28% male. Total population estimate for WV #1 was 337 wood turtles, with an aquatic density of 1,980 turtles per Hectare of river and a terrestrial density of 22.5 turtles per ha of terrestrial habitat. Growth measurements and estimates indicate rapid initial growth tapering off at year 8 and gradually declining through year 16. Males grow slightly faster …
