Electrofishing - DMR will present on Electrofishing

Fin Clipping 2016 Hundreds of hours put in by volunteers fin clipping in 2016 and clipping took just over 3 weeks to finish Fin clipping also included DSF staff time, including 5 contracted workers. Also, thank you NOAA, USFW, and DMR for your clipping contributions.

Stocking 2016 Stocking densities increased to from 120 to 150 parr/unit. Northern Stream was increased from 45 to 60 parr/unit. 199,644 fall parr stocked in 2016 The only site stocked below the smolt trap was the habitat in downtown East Machias. 18 sites were stocked (Mainstem and 7 tributaries) Harmon and Creamer Brook were fry stocked (10,300 fish) Beaverdam Stream (4 sites) Seavey Stream (1 sites) Barrows (2 sites) Northern Stream (3 sites) Richardson Brook (1 site) Pokey Dam - Mainstem Rte. 9 Rest Stop - Mainstem Great Meadow Riffles - Mainstem (2 sites) Downtown East Machias (1 site) Finished stocking by October 28 th Some sites not stocked due to extremely low water conditions: Outlet of Love Lake, Long Lake Stream, above Second Lake, other sites on Seavey Stream

Estimated Lengths At Stock Out USFW estimation method that utilizes fish per pound at stock out to get the length of fish 2012 sig. > 2014, 15, 16 2013 sig. > all years 2014 sig. > 2015, 16 2015 NOT sig. diff. than 2016 Tukey multiple comparisons of means. Like letters indicate no significant difference between years Thank you Colby

2016 Redd Counts 12 Redds found in the East Machias River System 2 in Great Meadow (Mainstem), 4 between Rte. 9 and Bdam Landing (Mainstem) including 1 ATS seen, 3 in Beaverdam Steam below Rte. 9, 3 in Northern Stream below 19 Rd. Majority of redd count trips were walked due to low water DMR smolt to adult return rates for 2016 16 adult returns estimated from DMR s equation. Smolt population in 2014 was 1019, which gives estimated smolt to adult return rate of 1.6%. This is comparable to naturally reared production and better then smolt stocking return rates.

2017 So Far Eggs delivered to East Machias 378,289 Received 154,769 on Jan 4 th, 162,244 on Jan 20 th, and 61,276 on Jan 31 st 90% hatch predicted for early March with transfer to SIBs 10,300 unfed fry will be stocked in Creamer Brook and Harmon Brook as in previous years Between eggs picked so far and classroom eggs the estimated number on station currently is around 367,000 eggs

8 Schools Fish Friends (formerly Salmon in the Schools) Peninsula School, RMG (Machias), Wesley Elementary, Elm Street School, Ft. O Brien, Jonesport-Beals, SHEAD high school, Alexander 1,600 eggs delivered

Changes and Adaptations Rachel Gorich hired as Assistant Hatchery Manager/Fisheries Biologist Kyle has shifted into land trust (35 mile campaign)/project management Zach moved into Hatchery Manager role Tweaked screen design to help with tank cleanliness Continued research into viability of having adult broodstock at CCAR in Franklin, Maine Expansion

- 36 x44 expansion off the back of the building. Could fit up to 15 tanks. - Partial funds raised with continued fundraising occurring as we speak Facility Expansion
