American shad are proving to be one of the most difficult anadromous species to successful pass at technical fishways, and an early determination of passage efficiency at Milford and Howland is critical to shad restoration on this river. If adult shad use the state-of-the-art fishlift that will constructed at Milford, they can be serve as broodstock for the hatchery and/or can be passed upstream to spawn naturally. 7.1.1 Identify potential sources of American shad broodstock (500-600 adults to produce 6M fry or 1000-1200 adults for 12M fry). The privately owned Waldoboro Shad Hatchery, which has provided fry for the Kennebec River Restoration Project, was modeled after the Pennsylvania Fish and Boat Commission Hatchery that has successfully supplied shad for the Susquehanna River restoration. The Waldoboro Hatchery currently requires 500- 600 adult shad broodstock to produce up to 6 million fry. At the start of the season, DMR trucks several hundred adult broodstock to the hatchery. The fish are allowed to spawn naturally in large indoor circular tanks; no hormones are used in this process. DMR trucks additional fish to the hatchery, which are added to the spawning tanks to compensate for spawning mortality or to replace spent fish. Fertilized eggs are collected, allowed to hatch, and transferred to fry tanks. Fry are fed, marked with OTC, and released into the river when they are approximately 21days old. PRFP Page 24
Because adult shad mortality increases with increasing temperature and distance that fish must be trucked, only sources of broodstock within a 5-6 hour drive were considered. Potential sources of sufficient broodstock in the Gulf of Maine are limited (Table 7). A remnant population exists in the lower Penobscot, but DMR estimates this population to be 1000 fish at most. In addition, capturing these fish for broodstock before the removal of Veazie and Great Works dams would be nearly impossible. Runs in the other Maine rivers are either too small, are undergoing restoration, or cannot be easily captured. The nearest source 13 of 1000-1200 adults within the Gulf of Maine is the Merrimack River (Table 7). This quantity of broodstock is also available from the Connecticut River, located outside the Gulf of Maine. During the development of this operational plan, we reviewed the best available information regarding the genetic structuring of shad populations on the east coast in order to assess the potential impacts of using out-of-basin shad broodstock for the Penobscot River restoration. This analysis is presented in Appendix A. Table 7. Nearest potential sources of American shad broodstock. River system Distance Status of run Penobscot 0 mi Size unknown, not easily captured Kennebec/Androscoggin 58 mi Size unknown, ongoing restoration, not easily captured Narraguagus 72 mi 100 adults in 2008 Saco 93 mi ~1200 adults, ongoing restoration, capture at fishlift Merrimack 125 mi ~29,000 in 2008, ongoing restoration, capture at fishlift St. John 179 mi Less than 1000 in 28 of 29 years from 1974- 2002 7.1.2. Double capacity of Waldoboro American shad hatchery. The Waldoboro Shad Hatchery currently can produce up to 6 million fry per year. It would have to be expanded to produce 12 million fry per year, which could be accomplished in less than one year if funding becomes available. 7.1.3 Develop an assessment plan for evaluating the effectiveness of the American shad hatchery stocking program (per ASMFC protocols). Amendment 1 to the Interstate Fishery Management Plan for Shad and River Herring requires that states with a hatchery program must submit proposals for evaluation and provide information in the annual report of the hatchery contribution (percent wild versus hatchery fish for juveniles and adults). Most programs mark hatchery fry with OTC, which shows as a fluorescent ring on the otolith. Samples of emigrating juveniles and returning adults are sacrificed and their otoliths are 13 Distance measured from river mouth to river mouth. PRFP Page 25
