Comments:

The R/V Lake Char was built as a replacement for the R/V Judy which has been used on Lake Superior since 1981. The primary duties of the R/V Lake Char are conducting the gill net survey work of adult and pre-recruit lake trout on Lake Superior. The vessel is designed to accommodate additional survey gear for future studies such as equipment used for trawling, trap netting, deep-water gill netting and hydroacoustic studies. The R/V Lake Char is powered with twin Caterpillar C-12 diesel engines which are rated at 454 bhp each. During the 2019 field season the crew collected 4874 fish of various species in 221,100 feet (41.9 statue miles) of gill net. The Lake Char had 390 hours of sea time.  For more information see: Michigan DNR site.

Added trawling gear and hydro acoustic equipment to help aid in our research on Lake Superior
