This document discusses demand feeders, which supply food to fish based on their appetite to prevent overfeeding and promote growth. There are two types of demand feeders: pendulum feeders, where food hangs from a rod and falls into the water when fish touch it, and submerged feeders, where food is transported on plates that fish can access by touching. Demand feeders are beneficial because they allow fish to eat according to their hunger and are cost effective and easy to use for aquaculture management.

Demand Feeders

2. INTRODUCTION
OBJECTIVE
It's the type if feeding technique according to the requirements of
fish for the necessary requirement nutriention that will enhance the
growth of the fish.
This type of feeding usually practice by all cultivators that will
prevent over feeding which can lead to many disease to fish.
To analyze the importance and objective of demand feeding.

3. Demand feeding can be of two types:
1. Pendulum feeding
2. Submerged feeding
1. Pendulum feeding:-
Where the food are hanged on the
container that attach to the rod or thread
that submerged in the water when the
fish usually touches the rod then food
usually falls on the water surface and
Fisg usually feed themselves.
2. Submerged type feeders:-
The submerged type feeder where the
food are being transported on the plate
where the fish usually touches the
plates and feed them through the plates.
As it can be easily accessible to both
younger Fish and as well as bigger fish.

4. DISCUSSION AND CONCLUSION
REFERENCE
The feeding of the fish usually being done according to the appetite of the fish. The fish
usually touches at the particular point of the surface when the fish being hungry and thus
supply food to those who are hungry.
The feeders as Fish is very important technique for the proper growth and development of
the fish and this helps to manage the aquaculture. Demand feeders are very cost effective,
easy to access and very beneficial for fish as well.
