Dolphins, mercury and human health

Dolphins, mercury and human health

Dolphins play a role in our health, warning us of dangerous levels of mercury in the fish and shellfish we eat.

A study from Gregory D. Bossart, John S. Reif and Adam M. Schaefer at Georgia Aquarium, Colorado State University and Harbor Branch Oceanographic Institute reveals dolphins are "canaries in the coal mine" when it comes to detecting our oceans' problems.

Protect yourself from Mercury
- Eat 8 or more ounces of seafood per week for overall health.
- If you are pregnant, eat at least 8 ounces and up to 12 ounces of seafood per week.
- Choose lower-mercury fish and shellfish including shrimp, pollock, salmon, canned light tuna, tilapia, catfish and cod.
- If you are pregnant or breastfeeding, avoid eating shark, swordfish, king mackerel, and tilefish from the Gulf of Mexico, and limit consumption of white (albacore) tuna to 6 ounces a week.
- Check your state's fish consumption advisories to learn which sources of local seafood may be unsafe.

Ecoclimax is defined by Odum (1969) as the culmination state after a succession in a stabilized ecosystem in which maximum biomass (or high information content) and symbiotic function among organisms is kept per unit of available energy flow.
