The document discusses different fish feeding techniques including filter feeders, scavengers, ambush feeders, gulp and suck feeders, and surface feeders. It also briefly covers common fish diseases like ich, hole in the head disease, and fungal infections.

1. Fish Feeding Technique
By Mr. “Eating Is Fun” Chapman

2. Feeding Technique
• Types:
• 1. Filter Feeders
• 2. Scavengers
• 3. Ambush Feeders
• 4. Gulp and suck
• 5. Surface feeders

3. Filter Feeders
• Filter feeders suck in water and food like
phytoplankton and zooplankton stick to
filaments, which are then digested.
• These fish usually have very large mouths
and are located on the front of their head.

5. Scavengers
• These type of fish are the clean-up crew
of the rivers/lakes.
• These fish eat anything that is organic
(dead or alive).
• Mouths are usually located on the front or
bottom of the head.

7. Ambush Feeders
• These fish hide and wait for a smaller fish
to swim by its mouth, and then they jump
out and grab the prey.
• Predators may wait days for prey to swim.
• Their mouths are located on the front or
top of their head.

9. Gulp and Suck
• These fish move around slowly, in a
stealth like mode and when they get near
prey they suck in water, which creates a
current that sucks the prey into the
predators mouth.
• Their mouths are located on the front or
top of their head.

11. Surface Feeders
• These fish feed off animals on the surface
of the water or out of the water.
• These fish usually have very developed
eyes.
• These fish mouths are located on the top
of their head.

13. Fish Diseases
• Ich – is an external parasite, looks like
little white dots all over the fish.
• Ich is the most common type of disease.

14. Fish Diseases
• Hole in the Head – caused by vitamin
deficiency or dirty water, skin breaks open
and you have a decay of tissue.

15. Fish Diseases
• Fungal Infections – see white patches
form on the fins and or body.
• Looks like pieces of cotton.
• Caused by dirty water and malnutrition.
