[Parenting] Fish sounds, can protect fish from overfishing


During the mating season, the fish make a loud noise. In fact, the expression "noisy" is not appropriate. The sound of the fish can be heard right off the sea, and the scientists figured out how to deal with it.

Listening to the sound on the water, you can get a rough idea of ​​how many fish are below sea level. A considerable number of fish are gathered together, and if you throw a net here, you will catch a huge number of fish.

Marine scientists at the University of Texas Marine Science Institute (UTMSI) in Fort Arrasas, Dexas, and scientists at the Scripps Institution of Oceanography, University of California, San Diego, .

"Fish spawning is very short or long and sometimes very deep, so it is very difficult for us to fully comprehend it," said Brad Erisman, assistant professor at UTMSI. "Our study presented one possibility for the exciting spawning season of fish," he said in a study published in the June 13th Science Report.

A variety of different species of fish are making sounds that seem to go away, but the researchers focused especially on early Gulf. This is because it is the most abundant fish around California.

Erisman said how loud the fish was. The sound is about 192 decibels, and it is a noise that can be deaf if it is on the ground.

Fishermen use this noise to find out where the fish are gathering and overfeed the fish. A recent fishing report compared illegal fishing records with the number of fish caught. The result was a shame we should be aware of.

Timothy Lowell, senior author of the study, stressed that overfishing the fish would eventually become extinct and harm the ecosystem.

Lowell and Erisman and researchers are trying to locate and protect the fish by monitoring the sound of the fish. They said that the fish themselves are interested in breeding and living.

Data The online site, called MARES (dataMARES), provided information on the number of early populations and explained how to protect them.

The National Oceanic and Atmospheric Administration, the Walton Foundation, and the David and Lucille Packard Foundation are sponsoring the project.
