The Senate voted 46-0 on Monday night for the moratorium.
Legislation initially called for a ban. Animal rights organizations, including the Humane Society and the Save the Rays coalition, say the contests are inhumane and harmful to the environment.
But some opponents of a permanent ban say the rays have been identified as damaging to the Chesapeake Bay’s oyster and blue crab populations. As a compromise, the legislation was changed to have a moratorium in place until July 2018. The Maryland Department of Natural Resources will complete a study by the end of the year.
The bill now goes to the House of Delegates.
