Fish Might Stop Swimming in Schools

[WB Staff]

Modern industrial fishing technologies may threaten the practice of fish swimming in schools, a new study shows.

Life on Earth is all about strategies for survival, with every organism developing behaviors and bodies that maximize chances of staying alive and reproducing while minimizing the likelihood of being injured or eaten.

Fish are one such example. For millions of years, many species have evolved a safety-in-numbers strategy that confuses predators and ensures the survival of the maximum number of individuals as they move about in the ocean.

But now, due to modern industrial fishing practices and technologies, schooling behavior may become less common.

“The findings from our model suggest that industrial fishing can decrease the tendency of fish to form large groups,” says Ana Sofia Guerra, a graduate student researcher at the University of California, Santa Barbara and lead author of a paper in the Proceedings of the Royal Society B.

This change in behavior has implications for both the fish and their predators, including humans, researchers say.

Everybody spent all that money on A-rigs for nothing?

Changes to instincts that have been developed through Ions of Evolution generally take a very long time to erase from a species . If this researcher's premise is correct how can it be that since the invention of the automobile deer still haven't evolved to the point of recognizing moving automobiles (and roadways )as a threat and simply avoid them ?
