The Mid-Atlantic Fishery Management Council’s Ecosystem Approach to Fisheries Management (EAFM) uses ecosystem indicators within a risk assessment framework to identify high-priority issues for further development of potential management actions, as described here.
Development of conceptual models to address management questions regarding the highest priority ecosystem factors is the second step in the Council’s EAFM Guidance Document framework. These models are built to ensure that key relationships throughout the system are accounted for. Utilizing the results of the risk assessment, the Council agreed to begin piloting the development of a summer flounder conceptual model that will consider the high priority risk factors affecting summer flounder and its fisheries.
This page provides interactive views of the full draft conceptual model for summer flounder developed for the Mid-Atlantic Fishery Management Council by a working group:

| Biomass distributional shifts (North/South) | Many of the current allocation discussions have focused on reallocation scenarios that are being driven, in part, due to distribution shifts or range expansion of biomass. As the summer flounder biomass changes over time due to climate and/or stock rebuilding, consideration of biomass distribution in any allocation scheme will be needed. Current commercial summer flounder amendment considered, although not selected, stock distribution changes for potential reallocation schemes. | Y | NEFSC trawl survey and other state and multistate (i.e., NEAMAP) survey information; commercial ammendment DEIS; 2018 benchmark stock assessment | North/South |

| Compliance/mislabeling (eg. RSA) | (From http://www.asmfc.org/species/summer-flounder): “Although reported landings have equaled or only slightly exceeded commercial quotas and recreational harvest limits in recent years, there is evidence of substantial illegal harvest in the form of unreported, underreported, or misreported landings. In 2013 and 2014, two separate investigations revealed that large quantities of summer flounder were being taken illegally under the guise of quota acquired through the Council’s Research Set-Aside (RSA) program (the Council subsequently suspended the program in order to consider alternative cooperative research options). There may also be substantial non-RSA related illegal/unreported landings, although fewer details are available on the extent of unreported landings outside of the RSA program. While the exact amount of illegally harvested summer flounder is not known, the effect may have resulted in substantial overages of the fishery’s annual catch limits (ACLs).” | NA | NA | NA |
| Shoreside support businesses | See Shoreside Support Risk Element below for additional details. Availability of support infrastructure can differentially affect fishing costs, as lack of infrastructure at home ports could increase travel costs to and from available markets. | Y | Shoreside support can partially be assessed through the number of seafood merchant wholesaler, seafood product preparation and packaging, and seafood market companies and nonemployer entitites (Quarterly Census of Employment and Wages. US Department of Labor, Bureau of Labor Statistics. https://www.bls.gov/cew/home.htm; Nonemployer Statistics. U.S. Census Bureau.https://www.census.gov/programs-surveys/nonemployer-statistics.html). Nonemployer entities are businesses that have no paid employees (i.e. the owner is the workforce), while the shoreside support companies include all businesses with paid employees. Some state level data is not available due to confidentiality. Other support businesses such as gear manufacturers, welding companies, etc. are not available due to aggregation of statistics across industries. | State & County level data available between 2001 - 2017 (companies) and 2004 - 2017 (nonemployer entities). |

|---|---|---|---|---|
| Stock assessment | The assessment is the basis for setting commercial and recreational catch limits and is used to also seperate the ABC into landings and discards. Assessment results and uncertainty may not align with what is occuring on water (ie. assessment indicating low biomass or high F but on water is showing high/changing abundance). | Y | 2018 benchmark stock assessment; previous assessment reports/updates | North/South; Inshore/Offshore |
| Enforcement | Needed to help ensure various regulations and harvest/effort conrol rules (i.e. seasons, trip limits) are followed. Helps lower management uncertainty. Influenced by regulatory complexity and resources available at the state and federal level. | Y? | Law enforcement reports, citations (federal and state) | NA |
| Compliance | Need strong compliance of various regulations and reporting requirements to help ensure accurate info is collected and minimize management uncertainty. Increasing regulatory complexity, frequency of change, decreasing opportunity, perception of fairness, and lower catch limits all reduce compliance. RSA program non-compliance issues. Fishermen, both commercial and recreational, chosing not to abide by certain management measures because of perceived inequities in the management system or allocation schemes. | Y | MRIP data for non-compliance harvest; RSA review/non-compliance in NY; law enforcement reports | NA |
| Risk buffering and ABC/ACT determination | The Council’s risk policy, the SSC determination of scientific uncertainty and the Council’s implementation of management uncertainty (although typically not applied) reduce the OFL to the ABC. The uncertainty in the ABC and “buffering” may impact the Council’s control in limiting catch to the specificed limits (e.g. assessment/ABC not aligned with observations on water). The Council can insert addtional buffering and reduce the ABC to the ACT to account for management uncertainty. | Y | Stock assessment documents; Council risk policy and HCR documents; SSC meeting summaries | NA |
| Recreational data quality (landings/discards) | Recreational catch information are estimates and not a census and have some level of uncertainty - uncertainty increases as data is more refined (i.e. state, mode, season). Recreational estimates and methodolgy have changed a number of times over the last 10-15 years. Uncertainty may lead to implementation of recreational accountibility measures and reduced opportunities. Recreational discards are more uncertain and account for a high proportion of overall catch. Hook and release mortality estimates are dependent on time, season, gear and method of fishing. | Y | MRIP data; state volunteer angler data; staff/Monitoring Committee recreational documents and meeting summaries | NA |
| Commercial data quality (landings/discards) | Commercial landings are census data and assumed to be accurate/reported without error. Discards are estimated and can be uncertain - both discard amount and discard mortality. Uncertainty in estimates can lead to implementation of accountibility measures and additional restrictions. | Y | VTR data; observer data, dealer reports; assessment and data update reports | NA |

| Interactions across Mid-managed and non-Mid-managed species | Regulations for other species managed by other Councils may result in increased regulatory discards, catch restrictions, and stakeholder confusion. For example, vessels fishing in the Mid-Atlantic exemption area (defined in the groundfish regulations) may land summer flounder up to state limits, but vessels fishing in the Southern New England (SNE) Exemption Area north must abide by more stringent regulations imposed from other fisheries managed by the NEFMC (e.g., the requirement for no possession any other species than scallops on declared day-boat scallop trips in the SNE Dredge Exemption Area results in discarding summer flounder). In addition, the accountability measures for windowpane flounder, if triggered, require the use of approved selective trawl gear in certain pre-defined areas.

| Regulatory and/or allocation inequities amongst states or sectors | Management actions (e.g., commecial summer flounder amendment) to address inequities and access can lead to increased regulatory complexity (e.g. more complex allocation shares) | NA | NA | NA |
| State allocation - lack of control in intrajurisdictional effort | Through the recreational conservation equivalency process and regulatory implementation, states have limited ability to control overall effort and therefore the expected catch/harvest associated with particular management measures. States then need to make continued adjustments to regulations in out years to account for under/over harvest in prior years. | Y | MRIP data; annual Council fishery information documents, ASMFC plan reviews and Monitoring/Technical Committee reports and memos. | NA |
| State allocation - inter/intra state jurisdicational challenges; conservation equivalency/out of state harvesters | State/federal regulations and requirements add additonal compexity and confusion to process. Coastwide management systems allow for greater regulatory consistency and potentially simplicity, but likely not equitable. State-by-state allocations - both commercially and recreationally - have allowed flexibilty for states in crafting measures that work for thier fisheries and state needs. That has led to greater disparity and complexity in regulations and regulation changes. In addition, conservation equivalency - even under regional approach - has created a system for states/regions to make continual small tweaks to measures as long as overall harvest in equivelent or within a specified harvest target. State allocations, particularly on the commercial side, has also increased the permitting system by creating state specific limited access programs and potentially limited flexibility and movement. These regulatory and/or permitting differences among states also make it difficult to predict out of state participation and harvest. | Y? | There is information available (ASMFC FMP reviews, Council FID, state specific websites) to document the regulatory and/or permitting differences between state/federal and states.

| State allocation - rec data parsed out too finely to generate precise estimates | Through the recreational conservation equivalency and regional management process, states/regions utilize the MRIP data at the state/wave/mode level to evaluate and develop management measures (e.g., shore based programs, for-hire specific regulations, seasonal (i.e. daily) adjustments. These adjustments within each state and region have added to the regulatory complexity, even when measures change little year to year, and evaluaon of implications/effectiveness of measures likely difficult given MRIP coverage and uncertainty. | Y? | MRIP data and state volunteer angler surveys; new F-basd evaluation by Fay and McNamee | North/South; Sector (for-hire vs. private) |
| Interaction with other MAFMC management regulations | Overlap, or lack there of, of other fishing opportunties and seasons - both commercial and recreational.

| Protected Species (ESA listed and MMPA proteced) Interactions with bottom trawl gear. | Summer Flounder Fishery is known to interact with small cetaceans protected under the MMPA, as well as ESA listed species of sea turtles and Atlantic sturgeon (e.g., MMPA LOF Category II fishery, sea turtle TEDS). This fishery, therefore, has an impact on the continued survival of these species. Monitoring protected species bycatch in the fishery and understanding the interaction risks to protected species posed by the summer flounder fishery now and in the future is needed to help better inform protected species management decisions (e.g., implement mitigation measures to reduce interaction risks to species of marine mammals, sea turtles, or Atalntic sturgeon). | Y | NEFSC FSB observer reports; MMPA LOF (https://www.fisheries.noaa.gov/national/marine-mammal-protection/marine-mammal-protection-act-list-fisheries); Warden 2011a,b; Murray 2015; sea turtle TEDS (50 CFR 223.206; sea turtle protection area maps:https://www.greateratlantic.fisheries.noaa.gov/educational_resources/gis/data/shapefiles/Summer_Flounder_Fishery-Sea_Turtle_Protection_Area/Summer_Flounder_Fishery-Sea_Turtle_Protection_Area_MAP.jpg; | North/South; Inshore/Offshore; Gear type |
| Distributional changes (summer flounder and protected species) | Changes in the distribtion or spatial overlap of summer flounder, its fisheries and protected species may result in higher/lower encounter rates.

| Windowpane flounder specifically; NEFMC groundfish generally | Regulations for other species managed by the NEFMC may result in increased regulatory discards, catch restrictions, and stakeholder confusion. Vessels fishing in the Southern New England (SNE) Exemption Area north must abide by more stringent regulations than when in the Mid-Atlantic. For example, the groundfish regulations outline specific exemptions for fishing for other species (i.e., scallops), but allow for no possession of any other species when on these directed scallop trips. Although not intended to impact MAFMC-managed species, in actuality there are implications. In addition, the accountability measures for windowpane flounder, if triggered, require the use of approved selective trawl gear in certain pre-defined areas. This gear is designed to minimize the catch of flounder. | Y | VTR data; observer data; dealer reports; VMS data; Regulations at 50 CFR 648 | North/South |

| Regulatory complexity | Increasing amount, freqeuncy and complexity of regulations has likely impacted recreational effort and participation. These impacts likely higher in the for-hire sector. | Yes? | MRIP data; state-specific license databases; state DMV records for boat registrations. Need to somehow evaluate regulatory changes to changes in recreational (for-hire, boat, private) participation. | For-hire/private mode |
| Economic Drivers (Growth & Properity) | Recreational opportunities will depend to some extent on the underlying economic dynamics experienced. At the very least, cycles of economic expansion and contraction should affect the distribution of fishing across modes, having value implications. | Yes | GDP growth, personal income, and consumer spending (including expenditures on recreational goods and services) can be found at https://www.bea.gov/news/glance | NA |

| Regulatory and/or allocation inequities amongst states or sectors | Management actions (e.g., commecial summer flounder amendment) to address inequities and access can lead to increased regulatory complexity (e.g. more complex allocation shares) | NA | NA | NA |
| State allocation - lack of control in intrajurisdictional effort | Through the recreational conservation equivalency process and regulatory implementation, states have limited ability to control overall effort and therefore the expected catch/harvest associated with particular management measures. States then need to make continued adjustments to regulations in out years to account for under/over harvest in prior years. | Y | MRIP data; annual Council fishery information documents, ASMFC plan reviews and Monitoring/Technical Committee reports and memos. | NA |
| State allocation - inter/intra state jurisdicational challenges; conservation equivalency/out of state harvesters | State/federal regulations and requirements add additonal compexity and confusion to process. Coastwide management systems allow for greater regulatory consistency and potentially simplicity, but likely not equitable. State-by-state allocations - both commercially and recreationally - have allowed flexibilty for states in crafting measures that work for thier fisheries and state needs. That has led to greater disparity and complexity in regulations and regulation changes. In addition, conservation equivalency - even under regional approach - has created a system for states/regions to make continual small tweaks to measures as long as overall harvest in equivelent or within a specified harvest target. State allocations, particularly on the commercial side, has also increased the permitting system by creating state specific limited access programs and potentially limited flexibility and movement. These regulatory and/or permitting differences among states also make it difficult to predict out of state participation and harvest. | Y? | There is information available (ASMFC FMP reviews, Council FID, state specific websites) to document the regulatory and/or permitting differences between state/federal and states. How to quantify this information and understand impacts? | NA |
| Communication and outreach | Ability for commercial and recreational fishermen to readily obtain and comprehend regulations and timing of disseminating information when regulatory changes occur. | Maybe - info on materials available but how to quantify | NMFS, Council/ASMFC, state level outreach materials, NEFSC stock assessment outreach coordinator | NA |
| State allocation - rec data parsed out too finely to generate precise estimates | Through the recreational conservation equivalency and regional management process, states/regions utilize the MRIP data at the state/wave/mode level to evaluate and develop management measures (e.g., shore based programs, for-hire specific regulations, seasonal (i.e. daily) adjustments. These adjustments within each state and region have added to the regulatory complexity, even when measures change little year to year, and evaluaon of implications/effectiveness of measures likely difficult given MRIP coverage and uncertainty. | Y? | MRIP data and state volunteer angler surveys; new F-basd evaluation by Fay and McNamee | North/South; Sector (for-hire vs. private) |
| Interaction with other MAFMC management regulations | Overlap, or lack there of, of other fishing opportunties and seasons - both commercial and recreational. Fewer opportunties (other fisheries open and/or available) during summer flounder season(s) could impact summer flounder effort and harvest - both recreational and commercial. | Y | Evaluation of state/federal seasons for different Mid-Atlantic species | NA |

| Fishery resilience (shoreside support) | Shoreside support (marinas, dealers, distributors etc.) are necessary for recreational and commercial products to reach markets and be consumed. | Y | Shoreside support can partially be assessed through the number of seafood merchant wholesaler, seafood product preparation and packaging, and seafood market companies and nonemployer entitites (Quarterly Census of Employment and Wages. US Department of Labor, Bureau of Labor Statistics. https://www.bls.gov/cew/home.htm; Nonemployer Statistics. U.S. Census Bureau.https://www.census.gov/programs-surveys/nonemployer-statistics.html). Nonemployer entities are businesses that have no paid employees (i.e. the owner is the workforce), while the shoreside support companies include all businesses with paid employees. Some state level data is not available due to confidentiality. Other support businesses such as gear manufacturers, welding companies, etc. are not available due to aggregation of statistics across industries. | State & County level data available between 2001 - 2017 (companies) and 2004 - 2017 (nonemployer entities). |

| Protected Species (ESA listed and MMPA proteced) Interactions with bottom trawl gear. | Summer Flounder Fishery is known to interact with small cetaceans protected under the MMPA, as well as ESA listed species of sea turtles and Atlantic sturgeon (e.g., MMPA LOF Category II fishery, sea turtle TEDS). This fishery, therefore, has an impact on the continued survival of these species. Monitoring protected species bycatch in the fishery and understanding the interaction risks to protected species posed by the summer flounder fishery now and in the future is needed to help better inform protected species management decisions (e.g., implement mitigation measures to reduce interaction risks to species of marine mammals, sea turtles, or Atalntic sturgeon). | Y | NEFSC FSB observer reports; MMPA LOF (https://www.fisheries.noaa.gov/national/marine-mammal-protection/marine-mammal-protection-act-list-fisheries); Warden 2011a,b; Murray 2015; sea turtle TEDS (50 CFR 223.206; sea turtle protection area maps:https://www.greateratlantic.fisheries.noaa.gov/educational_resources/gis/data/shapefiles/Summer_Flounder_Fishery-Sea_Turtle_Protection_Area/Summer_Flounder_Fishery-Sea_Turtle_Protection_Area_MAP.jpg; | North/South; Inshore/Offshore; Gear type |
| Distributional changes (summer flounder and protected species) | Changes in the distribtion or spatial overlap of summer flounder, its fisheries and protected species may result in higher/lower encounter rates. Interaction changes may be occuring with current species or new/different species in species moving in to area or fishery moving into a new/different area. | Y | VTR data; Observer data; summer flounder EA or EIS documents; | North/South; Inshore/Offshore; Gear type |
| Communication and regulatory complexity | Fishermen unaware of regulatory requirements and changes or confused by complex regulations which may lead to fishing practices that lead to increased technical interactions (e.g., utilizing wrong mesh size or fishing in closed area/season) | NA | NA | NA |
| Windowpane flounder specifically; NEFMC groundfish generally | Regulations for other species managed by the NEFMC may result in increased regulatory discards, catch restrictions, and stakeholder confusion. Vessels fishing in the Southern New England (SNE) Exemption Area north must abide by more stringent regulations than when in the Mid-Atlantic. For example, the groundfish regulations outline specific exemptions for fishing for other species (i.e., scallops), but allow for no possession of any other species when on these directed scallop trips. Although not intended to impact MAFMC-managed species, in actuality there are implications. In addition, the accountability measures for windowpane flounder, if triggered, require the use of approved selective trawl gear in certain pre-defined areas. This gear is designed to minimize the catch of flounder. | Y | VTR data; observer data; dealer reports; VMS data; Regulations at 50 CFR 648 | North/South |
