-Electronics away, in assigned seats please
-Open your notebooks to the next open right hand page and complete the WARM UP below.
WARM UP 10/6/17
1. Name at least three things you know about salmon (higher-level thinking).
-they are anadromous: can live in fresh and salt water
-females defend eggs until death after spawning
-a nest of eggs is called a 'redd'
-life cycle: born in fresh water, swim to ocean, live in ocean up to 5 yrs and mature, swim upstream to home waters, spawn, die
-carcasses provide nutrients to ecosystem
-main food source is macroinvertebrates ("bugs")
-they are endangered
-males develop a hooked jaw and teeth during spawning
-females lay 3,000-7,000 eggs in a redd
-hatcheries prevent upstream and downstream migration
-they are important in native american culture
-they are a global food source
-they are a 'keystone species' : many other organisms depend on them in their ecosystem
-females lay eggs for up to a week in one redd
-males can fertilize several different redds
-they use sense of smell and inner magnetic pull to return upstream to home waters
-hatchery fish are mainly for human consumption

Field Trip Debrief
Salmon Watch 2017 Photos
What I learned:
-the salmon we saw on the ZigZag River were Spring Chinook
-females spawn for up to a week long, laying the 3,000 to 7,000 eggs a little at a time in one redd (nest)
-Atlantic Salmon refers to the species, not the location. There are Atlantic Salmon that are farmed off the Pacific coast. The natural color of farmed salmon flesh would be grayish white because they are contained in tanks and don't eat naturally occurring food from the ocean. They are given additives in their pellets that makes their flesh the usual red color. Also, the waste under their cages kills all vegetation and causes sea lice. Don't eat farmed salmon - gross!
-the cage on the river was a temporary fish trap to separate wild and hatchery fish and prevent interbreeding
-all hatchery fish have had their adipose fin removed
