Escapted farmed salmon threatens wild salmon stocks across Northwest Iceland, where it has entered rivers.
Two Risso’s dolphins washed ashore in Hrútafjörður in Northwest Iceland last week. Risso dolphins are a warm-water species found a bit to the east of Ireland and Northwest Scotland. But the largest number is found further south, in warmer seas.
