Why do salmon lay their eggs in high stream-groundwater interaction zones?

		These zones are well protected from predators.
		The high flux of groundwater flowing into the stream reduces the stream’s temperature and provides the salmon with ideal condition for their eggs.
		The interaction creates oxygen-rich zones, which supports the salmon’s eggs.
		The interaction provides ideal conditions for algal growth, which the salmon offspring can feed on when they hatch.
