<p>&quot;The temporal and special characteristics of spawning herring aggregations in coastal Gulf of Maine waters have been studied during the fall since 1998. The program has attempted to estimate the biomass of herring spawning in these waters during the fall months to establish an index of spawning stock biomass. Surveys have been conducted from Cape Ann, Massachusetts to Cutler, Maine. Each year, techniques have been refined for implementing acoustic surveys and collecting representative biological samples on fishing vessels.</p>
<p>In March 2005, the Northeast Consortium funded and facilitated an independent peer review, which concluded that acoustic surveys are an appropriate way to survey herring in this area and recommended continuation of the project. It also recommended that future surveys focus on estimating biomass using a broad-scale systematic survey approach, as well as developing an annual &quot;sentinel&quot; acoustic survey of the important spawning grounds. This project continues with additional funds from the Northeast Consortium granted in 2005. The panel's recommendations are being incorporated into the work, with surveys focused on identifying and quantifying &quot;sentinel&quot; spawning grounds.&quot; <i>extracted from: Summary of Completed Cooperative Research Projects Funded by the Northeast Consortium, September 2006</i></p>
<p><b>Sub Areas</b></p>
<p>Each survey leg was apportioned into geographical sub areas prior to data analysis in order to allow for more precise target strength calculations for individual aggregations of fish. For any given leg, the observed distribution of Atlantic herring as well as the locations and distribution of biological sample tows were used to define between two and four unique sub areas for the leg. Data from all biological sample tows conducted within a given sub area were combined before calculating a target strength. This process should reduce the variance within each sub area biomass estimate and accounted for multiple sampling of the same fish aggregations.</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.

Specified by the Principal Investigator(s)
<p>When significant aggregations of fish were detected acoustically, the midwater trawl was set to confirm species identity and to collect approximately 100 individual Atlantic herring. Tows were conducted along the transect line after passing over the fish aggregations. Tow times were generally short in duration (10 - 20 minutes); just long enough to collect the necessary samples. All herring samples were frozen at sea for further laboratory analysis.</p>
<p>Back in the laboratory, herring samples were thawed out for examination. Natural length measurements were taken to the nearest 5 mm, total weight to the nearest 0.1 g, gonad weight to the nearest 0.1 g, sex and International Commission for the Northwest Atlantic Fisheries (ICNAF) gonad development stage (Table 3). In order to account for freezing and thawing of herring samples, length measurements were corrected using Maine Department of Marine Resources' correction equation:</p>
<p>Lmm = 4.1825 + 1.0051 * [Frozen Sample Length (mm)].</p>

Midwater Trawl
Midwater Trawl
PI Supplied Instrument Name: Midwater Trawl PI Supplied Instrument Description:17 x 15 fm midwater trawl net with a 17/8" mesh codend. The net included
a trawl monitoring system which relayed real time height of headrope from the sea bottom to aid with the collection of herring samples. Instrument Name: Midwater Trawl Instrument Short Name:TrawlMid Instrument Description: A mid-water or pelagic trawl is a net towed at a chosen depth in the water column to catch schooling fish such as herring and mackerel. Midwater trawl nets have very large front openings to herd schooling fish toward the back end where they become trapped in the narrow "broiler". The sides of the deployed net are spread horizontally with two large metal foils, called "doors," positioned in front of the net. As the trawler moves forward, the doors, and therefore the net, are forced outward, keeping the net open.
This instrument designation is used when specific make and model are not known. Community Standard Description: http://vocab.nerc.ac.uk/collection/L05/current/23/
