SSC Report to the CFMC on its November 12,2014 meeting

December 9, 2014St. Thomas, USVI

ACL Overages

• Puerto Rico Recreational– No overages

• Puerto Rico Commercial• 2010 species – Parrotfishes, Conch, Snappers, Groupers

• Snapper unit 2 (Queen, Cardinal Snapper)– 170% of ACL – Does not include 2013 data– 2010 was the high year, so should drop

ACL Overages

• Puerto Rico Commercial• 2011 species • Wrasses (Hogfish, Spanish Hogfish)– 114% of ACL – Does not include 2013 data

ACL Overages

• St. Croix (full data)• Angelfish, Squirrelfish, Wrasses are over

• St. Thomas (full data)• Angelfish, Squirrelfish, Wrasses are over

ACL Overages

Based on the limited data available and that these species (Angelfishes, Squirrelfishes, Wrasses) were not on the reporting lists until July 2011 for St. Thomas/St. John and St. Croix , and that there is no scientific basis for determining otherwise, the landings overages are assumed to result from enhanced reporting. This applies to the data from 2011 to 2013.

SSC Review of SEDAR 35(Red Hind)

Puerto Rico

• The SSC accepts the general outpput of the analyses, which showed a decrease in mortality in the 1990s, but we recognize that it is difficult to determine what is the current status because that would require using absolute values for the parameters. However, given that CFMC defines overfishing as SPR 20% and given that the SEDAR chose to use more conservative values, and the probability of overfishing is less than 50% suggests that there is no strong evidence of undergoing overfishing in Puerto Rico.

St. Croix

• The low sample sizes available to estimate mean length in recent years precludes any determination of stock status or probability of overfishing

St. Thomas

• The SSC believe that due to the closures in the 1990s, fishers moved from fishing at the aggregations, where large fish were readily available, to fishing other sectors of the red hind population (other locations) where these larger individuals were not readily available.

• Therefore, this resulted in a reduction in size of fish due to change in location rather than increased in mortality.

• This could be checked by examining the data during the spawning and non-spawning periods.

Model/Approach Recommendations

• The SSC agrees with most of the comments of the CIE reviewers on how to improve the assessment, but in evaluating these comments the SSC feels that overall the approach used by the SEDAR 35 were valid. CIE recommendations to improve the analysis were incorporated into the subsequent research recommendations

Model/Approach Recommendations

• The SSC accepted the explanations from the SEDAR working group that – Surplus production models were data limited– Reliable projections were not possible given data and

viable approaches used – Age/slicing: having problems with length of data sets then

not valuable approach• Length-based method used seems to be most

appropriate given limitations of data, but it is recognize that this model has its own limitations, which are addressed in the research recommendations.

Research Recommendations

• Accept list of research recommendations, which are as follows:– Basic fish biology research (e.g., age, growth, diet,

length/age-at-maturity, fecundity)– Gear selectivity studies• Discard studies

– Continued improvement of data collection programs

2015 National SSC MeetingFebruary 23-25, Honolulu

• ABC specification for data-limited and model-resistant stocks

• Implementation of National Standard 2 in the face of uncertainties

• Evaluating existing ABC control rules: issues, challenges and solutions

• Incorporating ecological, environmental, and climate variability in stock assessment and ecosystem based fishery management

• Building habitat condition in the stock assessment process and fishery management strategies

5-Year Research Plan

• Stock Status• Assessment of the Effects of Current Federal

Management Regulations • Ecosystem Based Research: Watershed Approach,

Large Spatial & Temporal Scale Studies• Fishery Associated Human Communities• New & Alternative Sampling Techniques• Draft plan is uneven and in some areas unfocused• First step is top provide summary statements for each

area to provide target goals so that research priorities are properly focused.

Species Selection CriteriaIsland-based FMPs

• Concept of Thresholds• Are there upper and

lower thresholds (lbs,$) for inclusion and/or exclusion of species?

• Where would thresholds be applied?

• Can concept of Ecosystem Component Species be applied?

Habitat Specificity Range Economic ImportanceTarget Species Bycatch Yearly Mean LandingsEcological Value Protected/Managed Resource

Species Selection Criteria Concept of Thresholds

• St. Thomas/St.John – 101 species (or groups)• St. Croix – 99 species• Puerto Rico–Commercial – 174 species–Recreational – 226 species

• All included species need ACLs

Species Selection Criteria Concept of Thresholds

Example: Puerto Rico commercial landings• 48 “species” within 99% cumulative landings• 125 species above 99%• Those above range from 3,000 lbs to 1 lb average• But include – Nassau, goliath, yellowfin & yellowedge groupers– Rainbow parrotfish– Cubera, dog, gray, schoolmaster & mahogony snappers– Sharks and rays

• Problems with FMUs and data at family level
