Overfishing can have serious consequences for marine ecosystems and fish populations. Some signs of overfishing include a decline in fish stocks, smaller average size of fish caught, an increase in the number of smaller, younger fish being caught, and a shift in the species composition of catches. Additionally, if fishing efforts are consistently targeting the same species without allowing enough time for populations to replenish, it can lead to overfishing. Monitoring catch data, conducting stock assessments, and implementing sustainable fishing practices are crucial to prevent overfishing.
