Multi-Year Environmental Trends Of Shrimp Black Gill (Hyalophysa Lynni) Prevalence In Texas Gulf Coast Shrimp Populations, Jillian L. Swinford, Joel Anderson
Multi-Year Environmental Trends Of Shrimp Black Gill (Hyalophysa Lynni) Prevalence In Texas Gulf Coast Shrimp Populations, Jillian L. Swinford, Joel Anderson
Gulf and Caribbean Research
Shrimp Black Gill, caused by the apostome ciliate Hyalophysa lynni, is an emerging disease impacting penaeid shrimp populations along the southeast Atlantic Coast and the Gulf of Mexico (GOM). Changing annual environmental conditions may drive infection levels of this parasitic ciliate in these populations, which comprise one of the largest fisheries in the United States. Hyalophysa lynni is established on the Texas Gulf Coast, and prevalence of this parasite has a strong seasonal and spatial trend, likely linked with high temperature and a wide range of estuarine salinities. Texas Parks and Wildlife Department monitored shrimp black gill in 2 …
Effects Of Closure Of The Mississippi River Gulf Outlet On Saltwater Intrusion And Bottom Water Hypoxia In Lake Pontchartrain, Michael A. Poirrier
Effects Of Closure Of The Mississippi River Gulf Outlet On Saltwater Intrusion And Bottom Water Hypoxia In Lake Pontchartrain, Michael A. Poirrier
Gulf and Caribbean Research
The goal of this study was to determine if Mississippi River Gulf Outlet closure by hurricane flood protection projects stopped saltwater intrusion, salinity stratification, and associated low bottom water dissolved oxygen in Lake Pontchartrain.
Benthic Nutrient Flux In A Small Estuary In Northwestern Florida (Usa), Guy T. Didonato, Emile M. Lores, Michael C. Murrell, Lisa M. Smith, Jane M. Caffrey
Benthic Nutrient Flux In A Small Estuary In Northwestern Florida (Usa), Guy T. Didonato, Emile M. Lores, Michael C. Murrell, Lisa M. Smith, Jane M. Caffrey
Gulf and Caribbean Research
Benthic nutrient fluxes of ammonium (NH4+), nitrite/nitrate (NO2- + NO3-), phosphate (PO4-3), and dissolved silica (DSi) were measured in Escambia Bay, an estuary within the larger Pensacola Bay system of northwestern Florida (USA). Our study occurred during a severe drought which reduced riverine inputs to Escambia Bay. Laboratory incubations of field-collected cores were conducted on 8 dates between June and October 2000 to estimate nutrient flux, and cores were collected from locations exhibiting a range of sediment organic matter content. NH4+ flux ranged from – 48.1 to …
Utilization Of Saltmarsh Shorelines By Newly Settled Sciaenids In A Texas Estuary, Bert W. Geary, Jay R. Rooker, James W. Webb
Utilization Of Saltmarsh Shorelines By Newly Settled Sciaenids In A Texas Estuary, Bert W. Geary, Jay R. Rooker, James W. Webb
Gulf and Caribbean Research
Post-settlement patterns of habitat use along saltmarsh shorelines of Galveston Bay, Texas were examined for three sciaenids; spotted seatrout (Cynoscion nebulosus), red drum (Sciaenops ocellatus), and Atlantic croaker (Micropogonias undulatus). Collections were made summer through fall of 1997 and 1998 using a 1.5-m beam trawl hand-towed along the outside edge of salt marshes. Sciaenids were collected from tidal pass, bay, and remote tidal creek areas to assess large-scale (bay-wide) patterns of distribution and abundance. Cynoscion nebulosus were smaller and most numerous at bay stations, with densities peaking in June. Conversely, S. ocellatus were collected …
Growth And Production Of The Dwarf Surf Clam Mulinia Lateralis (Say 1822) In A Georgia Estuary, Randal L. Walker, Kenneth R. Tenore
Growth And Production Of The Dwarf Surf Clam Mulinia Lateralis (Say 1822) In A Georgia Estuary, Randal L. Walker, Kenneth R. Tenore
Gulf and Caribbean Research
The bivalve Mulinia lateralis is a dominant member of estuarine benthos, but its presence and abundance in Georgia estuarine waters is sporadic over time. Recruitment and production was monitored from 1977 through 1981 at three inner and one outer more saline ( > 18 ppt) areas of Wassaw Sound. Until the winter of 1981, Mulinia lateralis was absent or at very low densities. Significant settlement occurred in January 1981 when densities in the outer sound reached as high as 63,000 individuals • m-2). The clam was more abundant in sandy mud (x̄ = 10,161 • m-2) than …
Classification Of Mississippi Sound As To Estuary Hydrological Type, Charles K. Eleuterius
Classification Of Mississippi Sound As To Estuary Hydrological Type, Charles K. Eleuterius
Gulf and Caribbean Research
Mississippi Sound is classified as to estuary hydrological type by the method of Pritchard (1955). Differences in salinity between surface and near-bottom water were calculated from 2,401 pairs of observations made at 90 stations from 4 April 1973 to 12 April 1977. Frequency distribution tables, constructed by tallying the vertical salinity differences into three classes corresponding to three of Pritchard's estuary types (A, stratified; B, partially mixed; D, well mixed) were used to assess salinity structure of the water column. The greatest variation as to type occurred from January through June. From July through December, the water column becomes predominately …
