Juvenile. Probably Oncorhynchus mykiss.
Wild, but feed daily.
A small fish with small scales & the over-all appearance of a miniature hump-backed salmon, ca. 12 cm long. Middle fish in the second photo. This fish was caught by local fishermen using a hand-thrown net.
Cultured rainbow trout. I saw a few in the river that fed this aquaculture facility, which could have been introduced deliberately or could have escaped.
One poor guy on his last breaths.
