3.  Fish feed is a major expenditure for fish
farmers.
 Good fish feed management can reduce
overall culture cost, improve fish farm
environment and ensure healthy growth of fish
stock.
 Fish feed management includes choosing the
right feed, using a correct feeding method,
calculating the feeding cost and ensuring the
cost effectiveness of fish farm.
INTRODUCTION

4. Categories of fishes based on food preference
Herbivore
• Prefers food
which are plant-
based
Carnivore
• Eats other
aquatic animals
Omnivore
• Eats both plant
and animal-
based foods
Few ornamental species are categorized as strictly carnivores or herbivores

5. Basic Food Elements Needed by Fish
 Protein provides energy and builds body tissues
 Carbohydrates source of energy
 Fats also energy foods reserved energy
 Vitamins assist in metabolic process in the body
• Oil soluble vitamins A, D, E, K
• Water soluble vitamins B, C, panthothenic acid, niacine, folic acid and others
 Minerals regulate fish activities and their physical structure

7. Feed Types
1. Vegetarian feed
Wheat bran, rice bran, weed, soy dregs, flour and peanut
cakes are suitable for freshwater fish.
2. Trash fish
Fishing by- catch or small fish is suitable for marine fish.
3. Pellet feed
There are dry and moist pellets. The former is more
popular. Pellet feed is suitable for both freshwater and
marine species.

9. How to choose right fish feed
By comparing
I. The nutritional requirement of the species
II. Availability
III. Price
IV. Storage method
V. Hygiene
VI. Environmental impacts of different feeds.

10. The Correct way of feeding
 Feeding must not be too much and too quickly. This wastes money and pollutes
fish farms.
 Observe how fish respond to feeding. Low consumption may be a sign of
disease or deteriorating water quality.
It is best to give frequent feeds in small quantities.
If using dry pellet feed, consider having an automatic feeding machine installed
to save manpower.
By Keeping farm management record helps to control Cost and select the right
feed and management approach. It helps to detect potential disease outbreaks at an
early stage.

11. Feeding Management Strategies
 Feeding is done at least twice a day
 For small fishes (live-bearers), feeding can be done based on demand (at satiation level).
 Artificial feeds such as finfish feeds, prawn feeds or combination of rice bran fish meal
(20-30 fish meal, 80-70 rice bran) commonly used as feeds.
 Broodstock given high protein foods.
 Larvae or fry given tiny live foods (infusoria, Artemia, Moina)
 Juveniles could be given commercial feeds.
 Feeding is done gradually, making sure all fish have eaten.
 Feeds must be evenly distributed to the grow-out areas.
 Avoid wastage of feeds

12. Feeding management is One of the important aspects in the breeding and culture of fishes.
Feeds must be cost-effective and efficient.
Proper management of feed gives better yield.
