Description
The Biwa Trout is a large, predatory salmonid fish endemic to Lake Biwa in Japan. It is known for its migratory behavior, moving between the lake and its inflowing rivers for spawning, and can display striking coloration during this period. Due to its significant size and specific coldwater requirements, it is not suitable for typical home aquariums.
