What is "sea fish"?

Sea fish refers to any fish species that live and breed in saltwater environments such as oceans, seas, and estuaries. These fish come in various sizes and shapes, from small sardines to large tunas and sharks. They play an important role in the food chain, serving as a food source for many larger marine animals such as dolphins, seals, and whales. Some sea fish are also commercially important for human consumption, and they are caught and sold by the fishing industry worldwide. However, overfishing, climate change and pollution are among the major threats that are affecting the populations of sea fish globally.
