Description

Polynuclear aromatic hydrocarbons (PAHs) derived from fossil fuels are found throughout the world’s waters. In particular, estuaries, the primary natal habitat for many marine species, are sinks for these compounds.

 

Chronic Exposure to Polynuclear Aromatic Hydrocarbons in Natal Habitats Leads to Decreased Equilibrium Size, Growth, and Stability of Pink Salmon Populations] Integrated Environmental Assessment and Management, 2007; Vol. 3(3):329-341

Newswise — Polynuclear aromatic hydrocarbons (PAHs) derived from fossil fuels are found throughout the world’s waters. In particular, estuaries, the primary natal habitat for many marine species, are sinks for these compounds.

Excessive amounts can adversely affect salmon populations. However, such effects may be masked by immigration of fish from unaffected areas.

In a new study published in Integrated Environmental Assessment and Management (IEAM), PAH contamination was simulated for a single pink salmon population in an Alaskan watershed. This salmon population has been monitored almost continuously for 70 years, since 1934. The size of the salmon diminished as their natal habitat became increasingly contaminated, indicating increased vulnerability to extinction.

According to the study’s author Ron Heintz, of the Alaska Fisheries Science Center and National Oceanic and Atmospheric Administration Fisheries, managers should view salmon populations in decline with a great deal of concern, especially populations exposed to PAHs and other contaminants during sensitive life stages. Management actions in such cases would be prudent given that once significant population declines have been detected in a population it may be too late to prevent further declines.
