1. Freshwater: Freshwater fish are found in bodies of water with low salt content, such as lakes, rivers, streams, and ponds. These waters are typically found inland and are not directly connected to the ocean. Freshwater fish species include trout, bass, catfish, and perch.
2. Saltwater: Saltwater fish are found in oceans, seas, and other bodies of water with high salt content. Saltwater fish species include tuna, salmon, cod, flounder, and sharks.
3. Brackish water: Brackish water is a mixture of freshwater and saltwater, typically found where rivers meet the ocean or in coastal estuaries. This water type has a moderate salt content and supports both freshwater and saltwater fish species. Examples include striped bass, snook, and flounder.
4. Pelagic water: Pelagic fish live in the open ocean, far from land. They are usually found in the top layer of water, known as the epipelagic zone. These fish species include tuna, mackerel, swordfish, and marlin.
5. Benthic water: Benthic fish live on or near the bottom of bodies of water, such as oceans, lakes, and rivers. They may inhabit coral reefs, rocky substrates, or soft sediments. Benthic fish species include flatfish, groupers, scorpionfish, and sea urchins.
Some fish species are adaptable and can tolerate a wide range of water conditions, while others are more specialized and require specific water parameters to thrive.
