Marine Fisheries - Toxic Chemical Contamination

Marine Fisheries

Toxic Chemical Contamination

Habitats Affected: Water column, shell bottom, SAV, soft bottom, ocean hard bottom

Common sources: herbicides, pesticides, and other toxic chemicals from agriculture, golf courses, urban development, marinas, fuels, automobile transportation, boating activity, and industrial emissions

Impacts

  • Heavy metals, petroleum products, and other toxins can kill sensitive shellfish larvae, or lower reproductive success and growth, impacting shell bottom habitat.
  • Toxins can accumulate in soft bottom, resulting in mortality or poor recruitment of benthic invertebrates or bio-accumulate in the tissue of top predators.
  • SAV can be intentionally or unintentionally killed by spraying for aquatic nuisance plant control. See Introduced and Nuisance species for related information.
