Annual landings of recreational species are estimated based on the results of recreational intercept surveys (catch data) and telephone surveys (effort data).
ACL is 5,050 lbs.
ACL was exceeded by 9.7 % or 488 lbs.
Wrasse landings peaked in 2008 and have declined steadily since then.
This decline occurred at a time at a time when effort was thought to have increased. It is not clear if increasing effort has led to the observed decline in the stock biomass.
The SSC made recommendations for further analysis of wrasse data.
Note: data incomplete for 2012.
ACL is based on average of 2010 and 2011 landings data
ACL was exceeded by 33% because of 2010 landings
Landings in 2011 were at the ACL level
Number of trips track landings
Number of fishers reporting varied over the years
There was no evidence from the number of fishing trips and number of fishers reporting in 2000 – 2011 that there have been any significant changes in reporting by fishers.
It is clear that there was a peak in reported landings in 2006 of approximately 240,000 lbs and a subsequent fairly rapid decline, apparently reaching the ACL by 2011.
ACL of 51,849 lbs was based on average landings of from 2000-2005 (OFL) and with 15 % reduction.
The ACL was exceeded by almost 5,000 lbs or 9.6%
Landings declined from 2009 to 2011 but remained above the ACL level
The number of fishers reporting varied only slightly between 2000 and 2010, but increased dramatically, by about 90%, in 2011.
The number of trips with reports of grouper increased from 2000 to 2004 and declined slowly after that except for 2009.
Based on expanded landings data, the ACL of 145,916 lbs was exceeded by 156,072 lbs or 107%.
It was exceeded in both 2010 and 2011.
Because of lack of staff at the Puerto Rico Fisheries Lab in 2010, the expansion factor 2009 was used in 2010 (Fig. 7). The expansion factor for 2011 was based on surveys conducted in 2011 of fishers and their catch.
Estimated landings or expanded landings are obtained by dividing landings by the expansion factor.
For example, if the reported landings in 2006 and 2011 were 100,000 lbs in both years, but the expansion factor was 0.5 in 2006 and 0.8 in 2011 then the expanded landings in 2006 would be 100,000/0.5 = 200,000 lbs and in 2011 would be 100,000/0.8 = 125,000 lbs.
There were fewer trips with reported Snapper Unit 2 after 2002.
However, the number of trips increased between 2009 and 2011.
The number of fishers reporting (unexpanded) almost doubled between 2009 and 2010 and then declined in 2011.
The CPUE remained steady
