Alpena Staff Repair Gillnets in Preparation for Spring Sampling Season
Midwest Region, January 20, 2006
Print Friendly Version
During the month of January, Fishery Biologist Adam Kowalski mended approximately 3,600 feet of assessment gillnet.  These nets consist of 100 ft panels of 2” to 6” stretch mesh strung in 1/2” increments and are used by the Alpena FRO for the annual fishery independent lake whitefish assessment in 1836 Treaty waters.  Mending consists of inspecting every net for holes, broken floats, and broken ties.  Holes are repaired by either sewing in new twine across gaps or by replacing large holes with new sections of net.  If nets are damaged beyond repair, replacement nets are built.

Net repair is very important for collecting accurate and consistent data during our annual fisheries assessments.  Nets must be strung similarly and repaired to the same standard each year to assure consistent gear selectivity across sampling years.  Net repair and construction will continue throughout the winter until spring assessments start.
