What are the sea fish?
For instance, herring and mackerel eat plankton and are often found just under the sea surface. Sole, plaice and most species of sharks and rays live on the bottom, where they hunt benthic animals such as worms, crabs and shrimp. Then you have the real predators: fish that hunt other fish, such as cod and sea -bass.
What’s the difference between saltwater fish and freshwater fish?
Freshwater fish have large, well-developed kidneys that are able to process vast quantities of water. Saltwater fish lose large quantities of internal body fluids through their gills because of osmosis. They replace lost water by consuming large quantities of saltwater.
Which is better fresh water or sea fish?
If you enjoy fish that have the flavor of the ocean, saltwater fish are the best option for you. In contrast, freshwater fish do not have a briny flavor and tend to have a milder flavor profile. If you are not a fan of the “fishy” taste of seafood, freshwater fish are the best choice.

Why can’t saltwater fish survive in freshwater?
The hypertonic cells within a saltwater fish absorb water out while keeping salt within. Of course, freshwater environments do not allow for this due to the lack of salt. The process of osmosis helps to regulate the concentration both inside and outside the body of the fish.
Is fish from the sea salty?
Water concentration inside a fish is higher than in the ocean itself because the ocean is so salty. As a result, most saltwater fish constantly lose water through their gills and skin.
