Northern Tilefish

Tilefish

Lopholatilus chamaeleonticeps

Size: to 42" and 50 lbs.

Habitat
Deep waters around offshore canyons

These strange deep-sea fishes are found in the walls of the offshore canyons, far below the range of scuba divers, although they are caught by deep-sea fishermen. Their population is extremely cyclical, with large die-offs from excessively warm water, and this precludes any long-term commercial fishery.

PCBs

Poly-chlorinated biphenols (PCBs) and heavy metals ( Pb, Cu, Ni, Cd, Zn, Ag, and Hg ) have become an issue of concern with artificial reef development, as popular reef building materials ( e.g., ex-Navy vessels ) may contain quantities of these toxic materials that may potentially be transferred through the food chain. This transference, or bioaccumulation, may have unforseen effects on the marine environment and, ultimately, human health through consumption of contaminated finfish and shellfish harvested from these reefs. However, thousands of ships have met their demise without the environmental cleansing and preparation that artificial reefs require, perhaps posing a potentially greater health risk to consumers and divers.
