The Alaska Blackfish is an extremely hardy little fish of the great frozen north. It is related to the mudminnows and pikes. This interesting little fish is blotched and mottled with ornate black and brown markings. It reaches a maximum length of 12 inches. The ability of the Alaska Blackfish to survive adverse environmental conditions is legendary. They survive in small backwaters, marshes, pools, and seasonal ponds on the tundra. During the harsh arctic winter, most of these areas freeze to the bottom, but the blackfish comes back, year after year.
