(a) If the Regional Administrator determines that the harvest quota for any coral bed will be reached prior to the end of the fishing year, NMFS shall publish a notice to that effect in the Federal Register and shall use other means to notify permit holders. Any such notice must indicate the reason for the closure, the bed being closed, and the effective date of the closure.

(b) A closure is also effective for a permit holder upon the permit holder's actual harvest of the applicable quota.
