Factors Affecting Survival and Growth of Juvenile Freshwater Mussels Cultured in Recirculating Aquaculture Systems
(North American Journal of Aquaculture, 2005)
Abstract.—Seasonal differences in glochidial maturity, substrate, and diet were studied to determine how these factors affect the survival and growth of juvenile freshwater mussels. Comparisons were made between juveniles ...
Spatial Trends in the Texture, Moisture Content, and pH of a Virginia Coastal Plain Soil
(American Society of Agricultural and Biological Engineers, 1997)
Soil texture, moisture content, and pH data from an agricultural field area of 48 _ 32 m in a Suffolk sandy loam soil in the Virginia Coastal Plain was examined for spatial trends. Trend surface analysis of sand, silt, and ...
A model for assessing the likelihood of self-sustaining populations resulting from commercial production of triploid Suminoe oysters (Crassostrea ariakensis) in Chesapeake Bay
(National Marine Fisheries Service Scientific Publication Office, 2003-10)
Culture of a non-native species, such as the Suminoe oyster (Crassostrea ariakensis), could offset the harvest of the declining native eastern oyster (Crassostrea virginica) fishery in Chesapeake Bay. Because of possible ...
Evaluating methods for estimating rare events with zero-heavy data: a simulation model estimating sea turtle bycatch in the pelagic longline fishery
(National Marine Fisheries Service Scientific Publication Office, 2012-07)
Estimating rare events from zero-heavy data (data with many zero values) is a common challenge in fisheries science and ecology. For example, loggerhead sea turtles (Caretta caretta) and leatherback sea turtles (Dermochelys ...
Effects of a simulated fishing moratorium on the stock assessment of red porgy (Pagrus pagrus)
(National Marine Fisheries Service Scientific Publication Office, 2006-10)
Much of the information available on the population status of a harvested fish species is obtained from landings data. When fishing restrictions are in place, fishery-dependent data are reduced and assessments rely more ...
Abundance of horseshoe crabs (Limulus polyphemus) in the Delaware Bay area
(National Marine Fisheries Service Scientific Publication Office, 2003-10)
Discusses a study on horseshoe crabs in the vicinity of Delaware Bay. Abundance of horseshoe crabs in the area; Factor that influenced horseshoe crab catchability; Mean abundance estimate for all crabs.
Potential causes of mortality for horseshoe crabs (Limulus polyphemus) during the biomedical bleeding process
(National Marine Fisheries Service Scientific Publication Office, 2006-04)
Biomedical companies catch and bleed horseshoe crabs for the production of Limulus amebocyte lysate (LAL), a product used for protecting public health (Berkson and Shuster, 1999). LAL is a clotting agent, derived solely ...
Effects of blood extraction on horseshoe crabs (Limulus polyphemus)
(National Marine Fisheries Service Scientific Publication Office, 2003-04)
Climate characteristics of the Big Levels region, Augusta County, Virginia
(Virginia Natural History Society, 1999)
Effects of forest harvesting best management practices on surface water quality in the Virginia coastal plain
(American Society of Agricultural and Biological Engineers, 2000)
Three small watersheds located in Westmoreland County, Virginia, were monitored to evaluate the impact of forest clearcutting on surface water quality and to evaluate the effectiveness of forestry best management practices ...
