👉 Morningtide is a term used in marine biology to describe the time of day when certain species of fish or other marine organisms are at their most active and productive. The term comes from the Greek word "morning," which means "daybreak" or "morning light." In marine ecosystems, this activity can be particularly pronounced during the early hours of the morning, as the sun is just starting to rise over the horizon, providing a warm and comfortable environment for most species.
