<p>This dataset describes the metadata associated with the winter flounder trap study</p>
<p><strong>Abstract:</strong></p>
<p>The goal of this project was to explore the feasibility of a seasonal commercial winter flounder trap fishery in Maine's inshore waters. Experimental flounder traps with two different opening designs were tested. In one design, a standard crab hoop was used. In the other trap design, a smaller (restricted) opening was used in an attempt to exclude a higher proportion of bycatch, particularly legal sized lobsters. A total of 1160 traps were hauled over 33 trips during three different seasons: early summer, early winter, and late spring. The highest catch rates of winter flounder occurred in late spring although overall catch rates were low, an average of less than half of a pound of flounder per trap. The restricted opening design reduced the bycatch of legal sized lobsters compared to the traps with the standard opening during one field season, but results from the second field season were inconclusive. While catch rates in this experiment were not high enough to justify the development of a commercial fishery at this time, results were encouraging and should be used to direct further experimental testing. Future work should focus on setting the traps in areas of higher winter flounder abundance, exploring seasonal timing of a potential fishery, testing alternative bait types and refining trap opening design.</p> Methods and Sampling: <p>METHODS<br />
<u>Gear Design and Construction</u><br />
Trap design was based on a historical design, used previously in the Gulf of Maine to target winter flounder with slight refinements to the entry design reflecting more recent advances in trap design technology and understanding of flounder behavior. Kelo Pinkham built all traps used in the experiment with assistance from fellow Boothbay fisherman, Jim Lowe. In early 2005, thirty (30) traps were constructed from lobster crates fitted with a standard crab hoop acting as one long head (entrance). The crab hoop measures 8 inches across and 2 ½ inches in height. It was hoped that this hoop would allow flatfish, crabs and some finfish to enter while excluding most lobsters.</p>
<p>&nbsp;</p>
<p>Prior research suggests that entry design is the most important variable in flounder traps. With this in mind, Pinkham decided to fit the experimental traps with a standard crab hoop, which measures 8 inches across and 2 ½ inches in height. This hoop should allow entrance of flatfish, crabs and some finfish while excluding most lobsters. These traps were tested in the first of 3 field testing components during the summer of 2005. Following the first field testing component, Pinkham also constructed and tested traps with a more restricted opening size of 1 ¾ inches (8" x 1 ¾"). During the second and third field testing components traps with both types of opening designs were tested.</p>
<p><u>Study Area</u><br />
The winter flounder traps were set in coastal areas of mid-coast Maine in Booth Bay, Linekin Bay and Sheepscot Bay as shown in Figures 1 - 3. Water depths ranged from 1 to 24 fathoms. Bottom type was varied and included mud, sand and rocky habitats.</p>
<p><u>Field Trials</u></p>
<blockquote>Field testing components occurred:<br />
• Summer 2005: 02 June 2005 - 06 August 2005<br />
• Winter 2005: 17 November 2005 - 31 December 2005<br />
• Spring 2006: 03 May 2006 - 16 June 2006

<p>Traps were baited with crushed mussels or a combination of mussels and herring in bait bags or jars and checked twice each week. For each trap hauled the date was recorded, soak time (days), location (latitude and longitude), and trap type (standard or restricted opening). Biological data collected included species identification, weight to the nearest hundredth of a kilogram and length to the nearest whole centimeter for each finfish species, and weight the nearest hundredth of a kilogram for crustaceans. In addition, environmental data was collected including water depth (fm), weather, wind speed (kt), and wave height (ft).<br />
Additionally, during the first field testing component, the sex and maturity stage of all winter flounder captured was determined. This information was not collected for the second field component since no winter flounder were captured. During the third field component this information was not collected since the traps were not fished by the project leader but by another fisherman who was not comfortable collecting this information.</p>
<p>During the first field testing component 30 traps were set. The traps were hauled during 10 trips between 02 June 2005 and 06 August 2005, with an average soak time of 8 days. All traps fished during this component were fitted with a standard crap hoop. Overall during this period, 253 hauls were made.</p>
<p>During the second field testing component 50 traps were set. The traps were hauled during 12 trips between 17 November 2005 and 31 December 2005, with an average soak duration of 4 days. Twenty-four (24) traps were fitted with the standard crab hoop opening, 25 traps had the restricted opening design. Overall during this period, 596 hauls were made. Traps with standard openings were hauled 297 times and traps with the restricted entry design were hauled 299 times.<br />
During the third field testing component 30 traps were set. The traps were hauled during 11 trips between 03 May 2006 and 16 June 2006, with an average soak duration of 4 days. Seventeen (17) traps had the standard crab hoop opening, 13 traps had the restricted opening design. The project leader recruited Herbie Burnham, a fellow mid-coast lobster fisherman, to set and haul the traps and collect data for this field component. Overall during this period, 311 hauls were made. Traps with standard openings were hauled 164 times and traps with the restricted entry design were hauled 147 times.</p>

NorthEast Consortium
The Northeast Consortium encourages and funds
cooperative research and monitoring projects in the Gulf of Maine and Georges Bank that have effective,
equal partnerships among fishermen, scientists, educators, and marine resource managers.
At the 2008 Maine Fisheremen's Forum, the Northeast Consortium organized a session on data collection and availability. Participants included several key organizations in the Gulf of Maine area, sharing what data are out there and how you can find them.
The Northeast Consortium has joined the Gulf of Maine Ocean Data Partnership. The purpose of the GoMODP is to promote and coordinate the sharing, linking, electronic dissemination, and use of data on the Gulf of Maine region.
The Northeast Consortium was created in 1999 to encourage and fund effective, equal partnerships among commercial fishermen, scientists, and other stakeholders to engage in cooperative research and monitoring projects in the Gulf of Maine and Georges Bank. The Northeast Consortium consists of four research institutions (University of New Hampshire, University of Maine, Massachusetts Institute of Technology, and Woods Hole Oceanographic Institution), which are working together to foster this initiative.
The Northeast Consortium administers nearly $5M annually from the National Oceanic and Atmospheric Administration for cooperative research on a broad range of topics including gear selectivity, fish habitat, stock assessments, and socioeconomics. The funding is appropriated to the National Marine Fisheries Service and administered by the University of New Hampshire on behalf of the Northeast Consortium. Funds are distributed through an annual open competition, which is announced via a Request for Proposals (RFP). All projects must involve partnership between commercial fishermen and scientists.
The Northeast Consortium seeks to fund projects that will be conducted in a responsible manner. Cooperative research projects should be designed to minimize any negative impacts to ecosystems or marine organisms, and be consistent with accepted ethical research practices, including the use of animals and human subjects in research, scrutiny of research protocols by an institutional board of review, etc.

<p><strong>ANALYSIS</strong></p>
<p><br />
<u>Fish Length Frequency Distributions</u><br />
Fish species captured in the traps included winter flounder, longhorn sculpin, Atlantic cod and shorthorn sculpin. Total length measurements to the nearest whole centimeter were collected for winter flounder, longhorn sculpin, and shorthorn sculpin; fork length was collected for the cod. Twenty-six (26) winter flounder in total were captured over the duration of the project ranging in size from 15 to 42 cm. Exactly half of these winter flounder (13) were at or above the minimum legal landing size of 30.5 cm. The length frequency distribution of all winter flounder captured is shown in Appendix I. Eight (8) longhorn sculpin were captured over the duration of the project. A chart displaying their length frequency distribution is also given in Appendix I of report (see link above). Two Atlantic cod were also captured during the fall sampling period. These cod measured 27 and 30 cm. Two shorthorn sculpins were captured as well; one at 20 cm and one at 23 cm.</p>
<p><u>Lobster bycatch</u><br />
The restricted entrance trap design appeared to capture fewer lobsters than the control trap design although average catch per trap was fairly low for both designs (Table 11). No legal sized lobsters were captured at all in the traps with the restricted opening design in 446 traps hauled.</p>
