7.0 Objective: Rebuild the American shad population to self-sustaining levels in historical habitat within 50 years. 7.1 Measure: Beginning in 2010 or 2011, restore approximately 633,300 American shad (Table 2) in 41-50 years by stocking 12 million hatchery-reared fry annually for 41-45 years above Milford Dam, Howland Dam, and/or West Enfield Dam. 7.1.1 Strategy: Identify potential sources of broodstock that could provide the 1000- 1200 adults needed to produce 12 million fry. 7.1.3 Strategy: Double capacity of Waldoboro shad hatchery. 7.1.2 Strategy: Use in-basin shad as hatchery broodstock as soon as possible. 7.1.4 Strategy: Develop an assessment plan per ASMFC protocols for evaluating the effectiveness of the hatchery stocking program and compared to . 7.1.5 Strategy: Monitor adult shad returns by annual counts at Milford, West Enfield, and Howland 10 bypass and weekly biological sampling at Milford. 7.1.6 Strategy: Assess and improve if needed upstream and downstream passage at barriers (see Passage and Connectivity objectives 16.1, 17.0, 18.0 and Non-native species objective 23.0 for timetables). 7.1.7 Strategy: Conduct bi-weekly beach seine survey to assess juvenile fishes. 7.1.8 Strategy: Conduct annual boat electrofishing survey to assess changes in community structure. 7.1.9 Strategy: Cease fry stocking when at least 633,300 adult shad are passed at Milford for five years. 7.2 Measure: Restore remaining reaches by allowing returning adults to pass upstream and reproduce naturally (if passage is effective) or truck fish returning adults upstream and allow to reproduce naturally. 10 Special techniques such as video monitoring may be needed at Howland.
