Counting Fish with Sound (IMAGE) University of Texas at Austin Caption A team led by marine scientists from The University of Texas Marine Science Institute and the Scripps Institution of Oceanography have discovered a way to use the incredibly loud, distinctive sounds that fish make when they gather to spawn--not to catch them but to protect them. The team developed an inexpensive yet accurate method for estimating how many fish are in a spawning aggregation, based on their mating calls. Accurate data on when and where fish spawn, as well as how many there are, would help fisheries managers design effective management practices and monitor the ongoing health of a fishery.
