Why do fish bite some days and not others?
Why do fish bite some days and not others? Each species of fish may prefer different temperatures. Some species may not be able to tolerate certain temperatures. If the water temperature gets too hot or cold, these fish tend to shut down. If the fish aren't biting, it may be due to the water being too cold or too hot for them to behave as they normally would.
What color do fish bite the most?
This work revealed that fish trained to attack either red or green exhibited a high degree of color selectivity: red targets were chosen correctly more than 80% of the time, and green targets were chosen correctly almost 75% of the time.
