Yes, but they are still killed by predatory species by the millions. I saw a film of a school of silvery bait fish attacked by sailfish and sharks, as well as by dolphins and diving birds. In the end hardly a fish was left, silver or no.

Right, that what confuses me on the assertion of sardines being somehow less attractive to predetors.
I realize the science is "there" but I question it.
