Fun Facts About Fish

| Students studying the salmon cycle |
Did you know that Pacific salmon are anadromous?
This means that the salmon breed and spend the early part of their lives in fresh water, but spend most of their time in the marine environment.
Different species and stocks of salmon spend different amounts of time in fresh water during the early part of their life cycles. For example, pink and chum salmon tend to migrate very quickly from fresh to salt water, shortly after they emerge from the gravel as fry. Sockeye and some chinook stocks tend to spend quite a bit more time in fresh water before moving to the ocean.

| Assorted Zooplankton |
Did you know that salmon fry eat microscopic organisms called 'zooplankton?'
When they first emerge as fry, having depleted the food reserves in the egg that they grow from, salmon fry must find other sources of energy and, in their early stages of life, this means chasing down small swimming or floating creatures called zooplankton.
