Bottom feeders are undoubtedly tasty, but one cannot confidently say they are healthy.
Lobsters, shrimp, clam, and catfish are just a few names of such fish that one would search for on the menu of any restaurant, but today, we will not be looking at this.
Instead, we will look at the healthier options, those fish considered non-bottom feeders, but first, let us understand what a non-bottom feeder is.
What fish is not a bottom feeder?
Bottom feeders, as the very name suggests, are creatures, mainly fish, that find their food from the bottom of the sea. As a result, they are known to contain high levels of harmful chemicals because of the contaminants found in the things that they eat.
It is crucial for children and expecting mothers to avoid them at all costs, as they can harm kids and babies. Some examples of bottom-feeding fish are flatfish, eels, cod, haddock, bass, grouper, carp, and bream.
Now, a non-bottom feeder is just the opposite. These fish stay away from the bottom of the sea, which means you often find them on the surface or somewhere in the middle.
That said, the following are the seven bottom feeders that do not eat from the bottom of the sea.
1. Tuna
Tuna is more of a pelagic fish, which means it feeds neither at the bottom nor close to the shore.
This is a fish that feeds somewhere in between. It is more of a predatory fish that plows through the ocean waters to find its food, which is other smaller fish.
The younger ones mainly feed on other crustacean fish, while the older tuna usually catch sardines, mackerel, and other slightly larger fish.
2. Trout
These fish feed on aquatic insects like leeches, worms, and crustaceans.
They live underwater but not at the bottom of the sea. Trout are creatures that like cool places of 10-15 degrees, which makes rivers, streams, and lakes their favorite.
You can even find them in the still waters. Some even live in ponds and feed on insects that they find there, like beetles, mayflies, dragonflies, and midges.
3. Salmon
These fish are opportunistic feeders, which is to say that they will eat almost anything they find. This can even include insects and other tiny animals found at sea.
However, they are not bottom feeders and spend most of their lives in fresh and saltwater, which means they are often victims of other predators, even humans.
Giant salmon prefer eating creatures like shrimp, squid, and even other forage fish.

4. Mahi-Mahi
Mahi-Mahi feeds on various fish, so they don’t need to remain at the bottom of the sea.
Primarily found in the Atlantic, Gulf of Mexico, and the Caribbean, their diet mainly comprises smaller ocean fish like juvenile tuna and other pelagic fish and invertebrates. Billfish, jacks, and pompano are a few other names that you can add to this list.
These fish mainly stay on the surface in the tropical and subtropical waters.
5. Angelfish
What is funny about the angelfish is that it is always hungry and on the lookout for food almost all the time.
Angelfish live at the sea’s surface and, like Salmon, are opportunistic feeders that prey on other smaller fish at sea. They are more omnivorous and, at times, feed on algae, plankton, and other small things they find in the sea.
Their favorite places are the quiet and slow-moving waters, mainly seen in the South American freshwater river basins.
6. Atlantic mackerel
These are mostly found along the North Atlantic Ocean and the Baltic Sea. They like swimming along the temperate and tropical seas and are sometimes seen along the shore.
Their favorite are the crustaceans like krill, shrimp, and copepods, creatures you won’t find at the bottom of the sea. They are also known to eat small fish, squid, and jellyfish.
Atlantic mackerel are often seen hunting in groups. They can dive to depths of up to 600 meters in search of food.
7. Turbot
These fish usually stay close to the store and are more like hunters at sea, finding and eating other smaller fish that they see around them.
Sprats and sand eels are their summer favorite, as they are abundant at this time of the year, along with some smaller mackerel.
And then, in the winter, there are the whitings and rocklings that they will catch and feed.
