Background

Marine invertebrates, such as lobsters and corals, are crucial to the health of marine ecosystems. Marine invertebrates often lack some of the more sophisticated cellular repair mechanisms that vertebrate species like whales have. Many of these species are experiencing unprecedented and alarming population changes and declines. More importantly many are important species for commercial fisheries. Therefore it is possible that environmental contaminants may be playing a role in their population changes.

For example, high levels of chromium (Cr), iron (Fe), manganese (Mn), nickel (Ni) and lead (Pb) were found in lobster (Panulirus gracilis) tissues from the discharge area of the submarine sewage outfall in Mazatlan Bay (SE Gulf of California) (1). Specifically the levels of lead (Pb) found in muscle tissue. High levels of metals in commercially important species pose a major health concern for humans worldwide.

Experimental Studies

We are currently developing the protocols to culture lobster cells and marine corals. We hope to begin testing toxicants in these cells soon.
