As these fragile young fish, known as smolts, run the gauntlet past the fish-farm cages conveniently placed on their migration routes down the sea lochs towards the open sea, they are ambushed by the unnaturally high concentrations of lice.

The young wild fish, known as smolts, which migrate from the rivers to the sea each spring, cannot cope with more than the odd louse yet now must run the gauntlet past the fish-farm cages on their migration routes.

If they survive a year of hungry scrutiny by Mount Tamalpais 'herons and osprey and raccoons, the young fish (now called smolts) one day stop fighting the current, drift downstream past the second-growth redwoods, past the tires and soccer balls and styrofoam cups, past the slumping, over-grazed hillsides of Olema, into the brackish waters of the creek's estuary at the south end of Tomales Bay.

But a new study by David Welch, Carl Schreck, and colleagues suggests that factors other than dams may also be vital to the survival of ocean-going juveniles (called smolts).

No matter how many smolts we dump in the river, the dams and other downstream factors out of our control decimates the population.

The loons would be transients stopping off for a quick fish or two maybe some of Fisheries and Wildlife's carefully-nurtured Atlantic salmon smolts . . ., as they generally settle down on lakes and ponds for breeding territory.

It is only in recent years that fisheries scientists such as Shelton have succeeded in tracking the oceanic wanderings of spring smolts – or rather, ‘post-smolts’, now that they have left the river.
