Summer Broodstock Collection
July - September
Summer is a transitional period for Craig Brook National Fish Hatchery. During the summer, staff can be occupied with caring for fry retained for domestic broodstock or parr production, assisting our state partners with the operation of fish traps, grounds care and maintenance projects.
For the past several summers, Craig Brook National Fish Hatchery has hosted resident volunteers. These volunteers, typically retirees, reside on station in their motor-homes from a few weeks to several months. Each group of volunteers offer unique skills and experiences; therefore they are able to assist hatchery staff with a variety of projects, from building storage buildings, developing filing systems, grounds maintenance and fish tagging.
Throughout the summer months, the Department of Marine Resources Bureau of Sea Run Fisheries and Habitat continues to transport sea run Penobscot Atlantic salmon to Craig Brook National Fish Hatchery to be used as broodstock. Although the run typically peaks in June, many fish are caught well into September.
In addition to Penobscot sea run adult broodstock, Craig Brook National Fish Hatchery rears broodstock for the six populations of endangered Atlantic salmon. These broodstock are initially obtained from each of the six rivers (Dennys, Machias, East Machias, Narraguagus, Pleasant, and Sheepscot) as wild parr. Our state partners begin collecting the parr, 100-250 per river, in late July and will continue into late September. Wild parr from each of the six rivers are housed for one year following capture in river-specific rooms in the Receiving Building. After one year, the parr are tagged and moved into the main hatchery building. These broodstock will be kept at Craig Brook National Fish Hatchery for an additional four years during which time they will be spawned at least once. For biosecurity reasons, both the Receiving Building and the broodstock rearing areas of the main hatchery building are closed to the public. However, there are broodstock viewing areas in the Visitor Center and downstairs in the main hatchery building.
Summer is the season for volunteers!
