Extends the authority of the department of environmental conservation to manage blueback herring

This bill extends the Department of Environmental Conservation's authority to manage blueback herring populations until December 31, 2029. It achieves this by amending the state's environmental conservation law to update the expiration date for the department's existing management powers. The change applies directly to the department and allows it to continue regulating aspects of the fish's habitat and population without needing new legislation during the extended period. The act takes effect immediately upon passage.
