Red Snapper Management Measures - SAFMC.net

determined by applying a 40% release mortality rate for red snapper (SEDAR 15 2008).
Effectiveness of closure was determined by comparing the magnitude of dead discards to
actual landings. Effectiveness of a closure for red snapper could be increased by closing
co-occurring species.
STEP 1 - Determine landings of red snapper during 2001-2006
Table 36. Landings of red snapper during 2001-2006 from headboat.

STEP 3 – Identify trips that target co-occurring species.
Identify trips that caught of co-occurring species during a seasonal closure.
STEP 4 - Determine incidental catch.
