Chum Marine Survival compared to SSRAA / DIPAC

NSRAA’s chum programs have struggled during the past 7 brood years, especially at Hidden Falls.

We are hoping that improved 3-yr-old returns in 2015 and early signs of success in our 4.0 production point to a turn-around.

2016 FORECAST - CHUM

Deep Inlet chum – 1,782,000 projection is about 75% of the 2015 return Hidden Falls chum – 1,433,000 projection is about 490% of the 2015 return. Let’s hope the 4.0 data and 3-year-old numbers equate to a large 4-yr-old return in 2016.

Southeast Cove chum – 165,700 projection. All fry were 4.0’s; strong 3-yr-old return.

Haines chum – 31,000 (est. 33,800 in 2015)

2016 FORECAST - CHINOOK

Hidden Falls Chinook – 5,400 projection is about 2,800 fish above 2015 return

?? Questions, Questions ??

1. What is the contribution of the Hidden Falls stock?

2. What is the contribution of the Medvejie stock at Deep Inlet? Bear Cove?

3. How do survival rates compare for the 4.0 groups vs. the regular groups so far? Is the 4.0 program working?

4. Do any Deep Inlet fish return to the Medvejie Rack?

5. How many Bear Cove released fish are intercepted in the Deep Inlet and Troll fisheries?

?? Questions, Questions ??

6. What is the age composition of the return?

7. How does the age comp compare with scale aging?

8. Do Bear Cove releases survive at the same rate as Deep Inlet releases for the Medvejie stock?

9. How many non-NSRAA fish are in the fishery?

?? QUESTIONS ??

Prior to otolith marking, we could only make educated guesses at best for many of these questions.

In most cases we could only speculate.

Otolith sampling gives us a much better grasp on what is happening with different stocks, release sites, and rearing strategies as well as insight into the makeup of the fisheries.
