Book Description
"Amendment 3 to the Spiny Dogfish Fishery Management Plan was developed by the Mid-Atlantic and New England Fishery Management Councils. The management measures include implementing a research set-aside program, updating essential fish habitat definitions, allowing rollover of specifications, and eliminating the seasonal allocation of the commercial quota. These administrative measures are intended to improve the implementation of the Spiny Dogfish Fishery Management Plan and provide benefits to the spiny dogfish fishery"--Cover letter.

Book Description
The United States Government Printing Office (GPO) was created in June 1860, and is an agency of the the U.S. federal government based in Washington D.C. The office prints documents produced by and for the federal government, including Congress, the Supreme Court, the Executive Office of the President and other executive departments, and independent agencies. The Coastal Zone Information Center (CZIC) collection provides access to nearly 5,000 coastal related documents that the U.S. Government Printing Office (GPO) received from the National Oceanic and Atmospheric Administration (NOAA) Central Library. The collection provides almost 30 years of data and information crucial to the understanding of U.S. coastal management and NOAA's mission to sustain healthy coasts. This is one of their documents.

Book Description
The spiny dogfish (Squalus acanthias) is a commercial shark species that was recently considered, unsuccessfully, for inclusion in trade-regulation lists due to international concern about its conservation status. The major commercial demand for the species is from Europe, where the Northeast Atlantic stock has been managed unsuccessfully because of dysfunctionalities of EU fishery governance. The demand from the EU market is primarily for adult females, with the U.S. North Atlantic stock being one of the major contributors to this market. This primarily female fishery has led to overexploitation and a drastic reduction in both adult female biomass and juvenile recruitment in the U.S. Atlantic stock, forcing the adoption of a Fishery Management Plan (FMP) under the requirements of the U.S. fishery management system. The stock is now considered rebuilt and the U.S. Atlantic spiny dogfish fishery was recently certified as sustainable. However, new management strategies are needed to maintain fishery sustainability in the long-term. The first objective of this study was to analyze the EU trade dynamic changes associated with the introduction of the FMP by employing social network analysis. Results indicate that the EU market demand favoured the development of dogfish fisheries in several countries in order to supply to the decrease in U.S. export, eventually affecting the global conservation status of the species. Moreover, the species listing for trade regulation would benefit the U.S. and will enhance the conservation of other regional stocks worldwide. The second objective of this study was to investigate on the sex ratio changes in fishery-dependent surveys conducted off Cape Cod, Massachusetts; and to evaluate these results in light of the sexual segregation occurring in the species. Results support the development of a male-only directed fishery off the northeast portion of the Cape Cod peninsula, based on season (summer and early fall) and time of the day (early morning). This fishery would likely enhance the sustainability of the local spiny dogfish populations by reducing fishing pressure on the adult female component. Finally, results suggest that sexual segregation in S. acanthias off Cape Cod corresponds to female avoidance of males, coupled with specific mating and/or feeding behavior by males.

Book Description
"The Regional Administrator (RA) of the Northeast Region of the National Marine Fisheries Service (RA) has the authority to review and approve exempted fishery requests if data show that they meet the requirements dictated by the Northeast (NE) multispecies fishery regulations (50 CFR 648.80). Representatives from the NE multispecies fleet submitted two separate exempted fishery request to the RA in December 2011, requesting that the RA consider an exempted fishery for spiny dogfish in a portion of the Gulf of Maine (GOM) and Inshore Georges Bank (GB) when fishing with gillnet, longline, and handgear (Figure 1). For an exempted fishery to be approved it must be shown, using the best available data, that the bycatch of regulated multispecies in the proposed fishery will be less than 5% of the total catch. Data from the Northeast Fisheries Observer Program (NEFOP) and at-sea monitors (ASM) were compiled and analyzed with reference to groundfish vessels using gillnet, longline, and handgear in the area requested. Upon initial review of the requested exempted fishery, it was clear that the original request would not meet the requirements for an exempted fishery. However, a large grouping of trips that were below the 5% threshold did emerge just to the east of Cape Cod, MA. Therefore, NMFS developed and considered three options, including No Action. Option 1 would allow fishing in this area from June through December for longline and gillnet gear and June through August for handgear. Option 2 analyzes an exemption for longline, gillnet, and handgear in the area year-round. Data from 2010 and 2011 show that if Option 1 is selected, it is likely that bycatch of regulated species (primarily Atlantic cod, pollock, Atlantic halibut, windowpane flounder, winter flounder, and haddock) would be below the 5% threshold for all trips that would occur under this exemption. On October 19, 2012, NMFS published a proposed rule for this action. During the public comment period, NMFS received a comment that we should consider including the portion of Cape Cod Bay south of 42° N in the exemption area. It was our initial determination that there was not enough data to exempt the area from the requirements of the NE multispecies regulations. Based on this comment, we made an additional data request to the Massachusetts Department of Marine Fisheries (MA DMF). MA DMF was able to provide some supplementary trips in the area from a historical dataset. When the area was expanded to include the portion of Cape Cod Bay west of 70° W and south of 42° 11.5' N, there were a total of 11 trips. Therefore, NMFS developed an additional alternative (Alternative 2) to create an exemption area to target spiny dogfish in this portion Cape Cod Bay. There was not sufficient data in other months of the year in this area to consider a year-round exemption. Further, there were some trips in these months that exceeded the 5% NE multispecies threshold. So a yearround option was not a viable option"--Executive summary (page 2).

Book Description
The usual approach to projecting the effectiveness of trip limits as a conservation tool is limited to consideration of observed landings of the particular species of interest. This report describes an alternative approach in which we develop a simple economic model to predict how trip limits affect fishing behavior. The principal point of departure for this model is that trip decisions are not based upon catch of the regulated species alone. Specifically, if a vessel owner can expect to earn enough revenue from the combination of the regulated species (up to the trip limit) and the component catch to cover its operating costs then the trip may be expected to occur. Conversely, if projected operating costs exceed potential revenues, the trip may no longer be profitable and would not take place. As a case study, the model was applied to trip limits proposed for the Spiny Dogfish Fishery Management Plan in 2000. Model results indicate that expected changes in the conservation benefits differ substantially when trip economics are explicitly considered.
