Pacific salmon depend on a healthy connected stream system Biology Diagrams Salmon Food Web -3 Procedure (Continued) Key message to share with students: A food chain only shows a single food path for an animal. A food web shows many paths. A food web demonstrates how species in an ecosystems are interconnected 6. Assign each group a stage of the salmon life cycle. One group can do both eggs and alevin. Stages include egg,
Between 1970 and 2015, seals and sea lions increased the amount of adult Chinook salmon they ate from 75 tons to 718 tons-double that of resident killer whales and six times more than the combined commercial and recreational catches. 36 Emerging science suggests that harbor seals inflict heavy tolls on juvenile salmon in Puget Sound and Hood

Salmon Food Chain Teacher's Guide Presented by the Pacific Salmon Foundation. 2 OVERVIEW: Students will watch a visually engaging presentation on the marine food chain of Pacific Salmon featuring images and videos of the different animal along the chain. We will take a look at what salmon typically eat and consider
Aquatic Trophic Productivity Model. The ATP model is a dynamic food web simulation model, linking the dynamics of river food webs to the physical and hydraulic conditions of stream habitats, the structure and composition of riparian zones, and nutrient subsidies delivered by adult salmon. A salmon has an amazing life. It is hatched from an egg, one of 3,000 his mother has laid in a freshwater stream laden with oxygen. She stays there for anywhere from six months to three years. In general, the diet of a young salmon consists of insects, minnows and plankton. Then she begins a migration to the ocean, which can be a very long journey. Once they reach the food-rich sea, salmon grow quickly, increasing their weight over a increasing production at all levels of the food chain, from bacteria and algae Effects of salmon-derived nitrogen on riparian forest growth and implications for stream productivity Ecology 82:2403-2409. 16 Hilborn et al.
