Pollution and benthic fish
From Coastal Wiki
Organochlorine compounds
Chronic PCB contamination might affect the breading success of benthic fishes. The starry flounder population in the San Fransisco Bay displayed reduced breading success in the 1980's. Although the San Francisco bay had a relatively low PCB content, the eggs of the flounders displayed elevated PCB levels. The breading success of species in Europe might also have been affected by relatively low levels of PCBs. [1]
Benthic fish have been shown to be vulnerable to high concentrations of PAHs [2]
