Yesterday several of us were in a debate about what species of fish were coldwater fish and which were warm water fish. I our main concern issue was on the pike and musky family. After a little research on google I have found the answer. I copied this from  http://wdfw.wa.gov/outreach/fishing/warmwtr.htm

It is the the Department of Fish and Wildlife for the state of Washington Web site. I took  a little quote from there site that seems  to answer the question.

"In the past, various warmwater species were called “spiny-rays” because most of them have rigid fin rays (spines). Salmon, trout, char and whitefish, on the other hand, have only soft rays. Fisheries managers today prefer the term “warmwater” game fish for the so-called spiny-rays, and “coldwater” game fish for salmon, trout, char and whitefish.

Warmwater species in Washington now represent four families: Centrarchidae, the sunfish family; Esocidae, the pike family; Ictaluridae, the catfish family; and Percidae, the perch family. Becoming acquainted with identification and habits of these fish will open new fields of interest and opportunity for anglers. For assistance identifying these species, the Washington Department of Fish and Wildlife has a poster titled "Warmwater Fish of Washington," and color illustrations of many species can be found in the fishing regulations pamphelt"

Bass, walleye, pike, musky, catfish, panfish are warm water game fish and the cold water fish are salmon, trout, char, and white fish.

If anyone kind find any other info on the subject I would appreciate it. It is sourced form a goverment web site so it could be full of S#!T
