  • CHALLENGES FACING VIRGINIA SHELLFISH AQUACULTURE

    Water Quality – impacts on hatchery production and grow-out Climate change – rising sea levels, temperature effects, faunal changes Harmful Algal Blooms (HAB) – increased frequency Vibrio concerns Coastal Growth – conversion of rural to urban Regulations – zoning ordinances; inconsistent use of residential areas Changing demographics – the age of the NIMBY Access – working waterfronts being converted to other uses
