Some Things We Learned Along the Way
1) Child's Glacier is 36 stories tall and 13 miles long.
2) Otolith= ear bones behind the brain used to ID hatchery of origin by analyzing growth rings marked by temperature changes or salt.
3) Upriver there is a boreal forest and downriver it is a temperate forest.
4) A slough is a body of water where water goes both directions.
5) There are 134 incubators at the Gulkana hatchery.
6) The pipeline crosses 5 water tributaries.
7) 70 million tons of sediment are deposited by the Copper River annually.
8) 60% of Sockeye commercial catch in Copper River fisheries were hatchery fish.
9) The second largest eruption on North America was Mt. Churchill.
10) The 1964 earthquake was one that happens every 400-600 years. (The delta is continually sinking and the earthquake happens relieving pressure and causing the plate to move up.
11) Deer were introduced to Cordova.
12) There are two bridges across the Copper River.
13) There is a 80% survival rate from green eggs to fry compared to 10% in the wild.
14) The pipeline is 48" in diameter.
15) Lichen= Algae + Fungi
16) Moose were transported to Cordova for subsistence purposes.
17) Miles glacier is 27 miles long.

18) 30, 000 personal use dip-net permits are issued annually.
19) Subsistence fishing takes priority over all others.
20) An average of 3 people are pulled out of the rivers in the Copper River region annually.
21) Tazlina means "Fast Water"
22) Only 500 fish annually can be caught in one fish wheel.
23) Red salmon are susceptible to IHN. ( A blood virus that will kill the fish when they are under stressful situations.)
24) Humans are immune to IHN.
25) The salmon population in the Copper River started dropping 3 years ago.
26) There are 8 tribes in the Ahtna land.
27) Most gill-net fisherman have at least 4 different nets with different depths and mesh sizes.
28) Pump stations are now being automated.
29) pipeline oil runs between 94-112 degrees Fahrenheit.
30) The pipeline is 800 miles long.
31) The pipeline is above ground so the heat from the oil doesn't thaw like crystals.
32) Otoliths form like crystals.
33) 250,000 eggs in each incubator.
34) 350 plus fisherman/woman on call for SERVS in the event of an oil spill.
35) Downriver hatcheries keep fishing feeding pens for their first year but Gulkana fishery releases fry into freshwater lakes.
