Prey Community

Prey community is an indicator in the Southern Coastal Systems in the Florida Bay sub-region. The prey community structure is simply the percentage of the fish prey base that are classified as freshwater species. This is based on the finding that prey are more abundant and have higher biomass when a significant component of all prey base fishes are freshwater species. Simply stated; prey productivity is greater at lower salinity and the presence of freshwater species is representative of that increased production.

How is it measured?

Prey community is an indicator in the Southern Coastal Systems in the Florida Bay sub-region. Fishes at primary foraging locations of wading birds nesting in Florida Bay have been quantified since 1990 at six mangrove locations in the Taylor Slough and C-111 drainage basins north of Florida Bay. The target is to have at least 40% of all prey fish be classified as freshwater with a percentage of higher than 5% indicating a positive response to restoration efforts.
