2.3 Reduction in total removals from prohibition in catch of red snapper
Methodology is similar to determining effectiveness of seasonal closure with exception
that reductions are applied to landings and discards in numbers for the sectors.
STEP 1 - Determine landings in numbers for red snapper during 2001-2006 using
information from SEDAR 15 (2008).
STEP 2 – Determine average landings in lbs from logbook and average sampled landings
from Headboat and MRFSS in numbers for 2001-2006.
