Scientists from Florida Atlantic University (FAU) determined the spawning grounds of the rock bass by recording their courtship and mating sounds. The research was published in the journal Fisheries Research.
A few months a year grouper fish (epinephelides) hundreds and thousands from the grouper family gather to mate. This makes the animals vulnerable to poaching and poaching. In a new study, scientists recorded the courtship and mating sounds of fish in three marine areas off the west coast of Puerto Rico. They focused on two species: Nassau groupers (epinephelus striatus) and blackfin groupers (epinephelus guttatus).
Underwater recorders recorded four minutes of ocean sounds every hour. The researchers found that around 500 meters from both spawning sites, courtship-related sounds were visibly emitted. They also uncovered previously unknown places where fish congregate. In the future, these areas may be closed to fishing during spawning to prevent grouper extinctions.
Previously recognized the reason for the interbreeding of ancient people.
