Species counts from control and gear manipulation trials to reduce bycatch of juvenile fish. Dataset Description: <p>The Maine Department of Marine Resources, in collaboration with three fishermen, tested five gear manipulations in floating near-shore pound nets to evaluate their effectivness in reducing the incidental take of juvenile American shad (<em>Alosa sapidissima</em>), blueback herring (<em>A. aestivalis</em>), and alewife (<em>A. pseudoharengus</em>), while maintaining the catch quanitity and quality of the target species.</p>
<p>Sampling hauls generally alternated between gear manipulation and control trials on a 3-day rotation. During each trip, a portion of the total catch was sampled for species composition. Length was recorded for a sub-sample of each species.</p>

Enterline, Claire. Reducing juvenile alewife, blueback, and american shad bycatch in the coastal pound net and floating fish trap fisheries. Northeast Consortium Final Report 11-142.</p> Methods and Sampling: <p>Control and gear manipulation trials were performed on a 3-day rotation (except for the trials testing the 6" mesh leader). During each trip, the species and size composition of the catch were sampled.</p>
<p>The following five gear types were tested:<br />
(1) a large (8' by 8') soft mesh escape panel, knotless 2" mesh size (at Richmond Island site);<br />
(2) a small (~ 2' by 4') soft mesh escape panel, 3" mesh size (at Bailey Island site);<br />
(3) a 3' by 6' aluminum panel with 3/8" vertical bar spacing (at Bailey Island site);<br />
(4) a 3' by 6' aluminum panel with 1/2" vertical bar spacing (at Bailey Island site);<br />
(5) a large mesh lead to the trap: 6" mesh size (at Hermit Island site).</p>
<p>For catches larger than 1 tray, the catch was sub-sampled using one random tray from the catch. All fish of the sub-sample were identified to the species-level and counted. The total length of the first 100 individuals of each species were measured to the nearest millimeter. For catches of 1 tray or less, the entire catch was sampled; all fish were identified and counted, and the first 100 individuals were measured.</p>
<p>The total catch was either counted in trays or estimated by the fisherman in total pounds (the number of pounds per tray was not estimated). Notes were taken regarding apparent fish behavior in response to the bycatch reduction gear and fishing methods, as well as fishermens' comments regarding the gear manipulations.</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>The Northeast Consortium encourages and funds <strong>cooperative research</strong> and monitoring projects in the Gulf of Maine and Georges Bank that have effective, <strong>equal partnerships</strong> among fishermen, scientists, educators, and marine resource managers.</p>
<p>Priority areas for Northeast Consortium funding include selective fishing-gear research and development. The development of selective fishing gears that enhance gear selectivity, target healthy stocks, reduce bycatch and discard, reduce or eliminate technical barriers to trade, minimize harvest losses, and improve fishing practices. Studies of new and developing fishing gears and technologies aimed at reducing environmental impact is funded under Project Development.</p>

Floating Pound Net
Floating Pound Net
PI Supplied Instrument Name: Floating Pound Net PI Supplied Instrument Description:The nets used in this study were floating pound nets, using floating toggles and buoys at the surface and held taught below the surface using anchors at the corners. Instrument Name: Floating Pound Net Instrument Short Name:Floating Pound Net Instrument Description: Pound nets are passive, stationary gear used for live entrapment of fish species. The gear is composed of fiber netting. Floating pound nets use floating toggles and buoys at the surface and are held taught below the surface using anchors.
A pound net consists of: (1) a net body or crib where the entrapment takes place, (2) a least one mesh heart that helps funnel fish into the crib, and (3) a straight leader or hedging which leads fish toward the crib. Fish swimming along the shore are turned toward the crib by the hedging, guided into the heart, and into the crib where they are removed.
