Environmental Change In The Coastal Environment: Challenges For The Selection And Propagation Of Filter Feeding Species In Aquaculture, Stock Enhancement And Environmental Rehabilitation, Roger L. Mann
VIMS Articles
Selection of species for aquaculture, fishery stock enhancement and environmental rehabilitation or restoration in the coastal zone requires consideration of the fact that species have evolved over geological time whereas changes in the coastal environment have occurred predominantly over recent historical time, often with the largest changes occurring within the past decades of human activity. The evolutionary issue is particularly noted with filter feeding molluscs, where extant species supporting both major natural fisheries and aquaculture have ancient lineages and evolved in environments that may have differed considerably from the locally turbid, nutrient enriched, disturbed (through watershed change and local activity) …
Linking Watershed Loading And Basin-Level Carrying Capacity Models To Evaluate The Effects Of Land Use On Primary Production And Shellfish Aquaculture, Mark Luckenbach, Harry V. Wang
Linking Watershed Loading And Basin-Level Carrying Capacity Models To Evaluate The Effects Of Land Use On Primary Production And Shellfish Aquaculture, Mark Luckenbach, Harry V. Wang
VIMS Articles
Aquaculture production of hard clams, Mercenaria mercenaria, in the lower Chesapeake Bay, Virginia, U.S.A., has increased dramatically within the last decade. In recent years concern has been raised that some growing areas may be approaching the exploitation carrying capacity for clam production. Preliminary calculations indicate that large-scale intensive clam aquaculture may be controlling nutrient and phytoplankton dynamics in this system. To date, carrying capacity models have not been applied to this system, but we are in the process of building models for that purpose. Moreover changing land use in the watersheds surrounding the clam-producing areas raises the need for an …
