what is the legal size for chinock salmon

Answer:

Ok, if the Idaho Fish and Game Commission sets a season for ocean-going Chinook salmon, Chinook that are over 24" in length and missing their adipose fin are considered "adults" and must be recorded on your Salmon Permit.  Ocean-going Chinook under 24" are considered a jack salmon and you may or may not be able to harvest them based on the bag limit set for the season.

For landlocked Chinook in Lake Coeur d'Alene, you can harvest two and they must be over 20" in length.  All other waters where we have landlocked Chinook, they are considered in your trout limit - so we can harvest 6 of any size.
