Abstract:

The Maine-New Hampshire Inshore Trawl Survey is conducted twice a year, for five weeks at a time, always starting in New Hampshire and ending off Grand Manan. The spring surveys start the first week of May, and the fall surveys start the first week of October. Data collected by the survey include: (1) Fish and invertebrate weights and lengths, (2) Biological measures (sex, maturity, age) for selected species, (3) Icthyoplankton samples (fish eggs and larvae), ended in 2004, and (4) Oceanographic data (salinity, temperature, depth). The survey has a stratified random design with a fixed component. The inshore areas sampled are divided into four depth strata, out to approximately the 12-mile limit. Strata 1: 5-20 fathoms. Strata 2: 21-35 fathoms. Strata 3: 36-55 fathoms. Strata 4: 56+ fathoms The coast is also divided into five longitudinal regions based on oceanographic, geologic and biological features. Together, 20 separate strata exist. The total survey area is approximately 4,617 square nautical miles. A target of 115 stations is selected for sampling each survey, resulting in a sampling density of 1 station for every 40 NM2. Of those 115 stations, 20 of them are fixed stations, sampled each survey. There is 1 fixed station per stratum, either designated due to its historical importance and representative nature or chosen at random. The remaining 100 stations are chosen at random. The F/V Robert Michael, a Down East 54 out of Portland, Maine, is the primary vessel used for this survey. It is owned by Robert Tetrault and Captained by Rob Tetrault II. In addition, a virtually identical sister ship, the F/V Tara Lynn, Captained by Sam Galli, has been used by the survey as well. The survey utilizes a modified version of the shrimp net used in Maine waters. It was designed by the vessel owner and net designer Jeff Flagg to fish for a variety of near-bottom dwelling species without targeting any specific component. It has a 2-inch mesh, with a 1-inch mesh liner in the cod end. The net is outfitted with the NetMindTM trawl monitoring system manufactured by Northstar Technical. This sonar system allows continuous monitoring of net dimensions during towing to assess consistency, maintain quality control, and provide swept area for biomass calculations. To provide data to state and federal fisheries managers on a variety of managed finfish and shellfish for the inshore Gulf of Maine, along the coasts of Maine and New Hampshire. The data is used in stock assessments and other regulatory processes. Data was published in 2010 on the OBIS-USA web site and is available at http://www.usgs.gov/obis-usa Record Count 38661, Taxa Count 147 Spatial Data Organization Information - Indirect Spatial Reference: Inshore Gulf of Maine, Direct Spatial Reference: point Geodetic Model: Horizontal Datum Name: North American Datum 1983
