This fish blog will answer the major question, “What do fish eat in the ocean?” we will also discuss the major factors that decide the diet of fish, the diet of the fish in the wild, and the diet of the fish in a controlled aquarium at your home.
What do fish eat in the ocean?
Following are the things that a fish can eat in the ocean:
- Algae
- Fungi
- Small fishes
- Reptiles
- Insects
These are the major foods of fish. The diet of the fish depends upon various factors such as the size, weight, and biology of the fish in the ocean.
What are the factors that decide the diet of the fish?
Following are the factors that decide the diet of the fish in the ocean:
Size of the fishes
The first thing is the size of the fish. Larger-size fishes have different habits of eating and small-size fishes have different habits of eating. For instance, a large shark can eat the flesh of a small fish. On the other hand, small fish like goldfish can eat shrimp and other plants in the ocean.
Type of feeder
The next factor is the type of feeder. Either the fish is a carnivore, omnivore, or herbivore. Herbivores are the fishes that eat mostly plant material as demersal fish which mainly feed on the algae of the ocean.
On the other hand, we have carnivore fish species such as sharks which only consume small fishes like goldfish, tuna, and other fishes. They don’t feed on plants because they are not able to digest them.
The last one is the omnivore and most fish fall into this category of eating. This fish can eat both the fish and the plant material. They are capable of digesting both the plants and the meat of the fish. The most common example of such fish is the Mollies which is a typical omnivore species of fish.
Level of feeder in the ocean
The next factor is the level of feeders in the ocean. Fishes are surface feeders and middle and ground feeders. The ground feeders usually eat plants and algae as that demersal fish.
The other type of feeder is the surface feeder which can consume the insects and other things that fall on the surface of the water. An example of surface feeders is Catlas which are able to feed on crustaceans.
The last type of feeder is the middle feeder which can consume a variety of smaller fish species. The most common example of middle feeders is tuna, swordfish, and sharks.
What is the diet of the fish in the wild?
The most common diet of the fish in the wild is the smaller fish. The wildest fish that is recognized so far is the shark which can tear its prey apart and can even feed on humans also. It is the deadliest predator of the ocean. If it smells blood in the water, it can run quickly and can reach its prey in no time.
The benefit of meat is more than you can imagine. The meat of smaller fish can give protein to the predators of the sea. The protein can help to build the muscles of the body and also act as an energy source for the body. The healthier the meat of the fish the stronger the predator will become.
What is the diet of the fish in the controlled environment of the aquarium?
The fish can eat a number of things in a controlled environment but the most common food of the pet fish is commercially available fish food which comes in a variety.
The first type of fish food has shrimp in it which is specifically designed for carnivorous fish species. You can give your carnivore fish species this food so it can benefit from the protein content of it. 40 to 45% of the food should be the protein in the diet of the fish.
The next type of fish food is plant-based protein. It is specifically designed for herbivorous fishes. They like to consume plant-based protein because they are not best at digesting meat protein.
The last type of fish food has both animal protein and plant protein which comes for omnivore fishes. Most of the fish present in the aquarium is the omnivores fish but it is best to recognize your fish first and then give food to it.
