1. Major Fish Feeding Types

2. 1. Predators
Feed on macroscopic animals.
Teeth for grasping and holding to seize their prey organism firmly.
Have large mouth, reduced gill rakers, large stomach and short intestine.

3. 2. Grazers
Grazing fishes take their food by bites on a
large spread of food organisms.
i.e. Butterfly fishes (Chaetodontidae) and Parrot fishes (Sparidae)

4. 3. Food strainers
Sieve water to get the food material
The gill rackers are numerous, elongated and closely set in
They filter large volume of water to obtain small sized planktonic organisms

5. 4. Food suckers
Fishes swallow their food by sucking the desired food or food containing material
e.g. sturgeon.
5. Parasitic feeding
Specialized mode of feeding and fishes are no exception to this highly evolved feeding habit
Feed on the body fluids of the host fish.
e.g. lampreys
