Dozens of baby shark carcasses were discovered scattered in sand near Mobile this weekend… Some with fishing nets still around them. Biologists with the Dauphin Island Sea Lab collected 57 Bull Sharks, which they will autopsy and then use for research. The Alabama Marine Resources Division is also investigating. Officials collected pieces of a gill net left behind. One of the nets requires a license and is supposed to be monitored when in the water. Officials say 57 is only a small portion out of Mobile Bay. They add the area will be patrolled more closely.
