Criteria for Species Inclusion in Fishery Management Plans
The report outlines criteria for species inclusion in island-based fishery management plans, covering national standards, stock management, and minimizing costs. It discusses key factors such as target stocks, ecosystem components, and economic importance. The suggested draft criteria include biology, habitat, economic significance, target species, and more. It emphasizes the need to consider vulnerability, habitat specificity, range, and economic value when determining species inclusion.

Criteria for Species Inclusion in Island- based Fishery Management Plans National Standards Draft Criteria Test Species Review Trial Application of Criteria Development of Thresholds
National Standards NS 1 requires a description of the species involved in the fishery Target stocks Non-target stocks Ecosystem component species
National Standards NS 3 a stock shall be managed as a unit throughout its range. Choice of a management unit may be organized around biological, geographic, economic, technical, social, or ecological perspectives.
National Standards NS 7 - management measures shall minimize costs and avoid unnecessary duplication Factors to be considered for inclusion within an FMP: Importance of the fishery Biological condition of the stock Management by other programs Competing interests and conflicts Economic condition of a fishery Needs of a developing fishery Costs balanced against the benefits

Draft Criteria Biology defined as question of vulnerability/productivity. Is species particularly at risk? Habitat Specificity defined as a question of vulnerability due to particular dependence on limited or vulnerable habitat during some life stage Range defined as whether species is either 1) effectively limited to local waters, 2) limited to EEZ, 3) spans both, or 4) is a HMS Economic Importance defined as total economic value, not just ex-vessel price. This would include, for example, nonconsumptive use, recreational value, targeted species, filler species and socio-cultural importance
Draft Criteria Target species vs Bycatch Landings to be used first to establish lower and upper thresholds for automatic rejection from or inclusion in an FMP, respectively. Ecological Value defined as having a unique or large ecological function relative to habitat (esp. coral reefs), or trophic/community structure, e.g., keystone species, apex predator, key forage species such that management is needed to sustain that function. Protected/Management Status defined as whether the species is fully protected or partially protected within an existing management framework within EEZ or local waters
Test Species and Data Selected species spiny lobster, dolphinfish, ballyhoo, octopus, mackerel and mullet Available data Puerto Rico Commercial Puerto Rico Recreational St. Thomas/St. John St. Croix The SSC recommends that that the 2005 east coast correction factor be re-examined by the PR DNER with the assistance of the SEFSC. 1988 2012 2000 2013 2000 2012 1999 2012

The SSC did not assess the following: Weightings among the various criteria How they would be combined (for example - mean, median) for an overall score How that score would be interpreted (scaled) for species inclusion on not
Dichotomous decision tree for automatic inclusion/exclusion of stocks based on thresholds
Thresholds Actual Thresholds were not developed Use of thresholds did not take into consideration the possibility of some species with low landings being considered as potential Ecosystem Component Species . The SSC requests that the SEFSC develop graphs of species landings (lbs and $) that could be used to see if obvious threshold break points can be identified
ACL Control Rules Discussion motivated by scalers used for setting the Management Buffer when determining ACLs: (1) 0.90 for normal species, (2) 0.85 = for species undergoing overfishing, and what to do when a species is determined it is no longer undergoing overfishing Process for overfished stocks conducted before the ORCS process developed
ACL Control Rules The SSC requests guidance on role of SSC for setting the ABCs Recommends that, given the 5-year experience working with ACLs within the US Caribbean and elsewhere in the nation concerning data-poor stocks, the process of setting ACLs be revisited from start to finish prior to developing island- specific plans Until then, the SSC recommends the CFMC keep using the current control rule under the rationale from which it was developed.
Abrir la Sierra, Bajo de Sico, Tourmaline (ABT) Closures The SSC recommends that it be allowed to review the scientific information relative to the ABT Closures prior to a final decision by the CFMC
