ISLAMORADA, Fla. (AP) - Traffic stops throughout the Florida Keys have turned up caches of shark meat, sailfish and whole lobsters.
      
Police, immigration officers and federal drug agents have set up checkpoints this weekend along U.S. 1, the island chain's main artery.
      
Florida Fish and Wildlife Conservation Commission agents say two trucks stopped at one checkpoint contained more than 300 pounds of shark meat, two sailfish and $5,000 worth of lobster.

Monroe County Sheriff's Sgt. Alberto Ramirez says radiographic imaging was used to help search vehicles for hidden compartments containing contraband.
      
The sheriff's office says a drug-sniffing dog at one checkpoint has found crack cocaine, cocaine, marijuana and prescription narcotics.
