89. You already have learned that the big fish in your pond will get much of their food from small plants and animals which grow in the green water.
90. To keep the water green, do not forget to put a bucket of fertilizer In the crib In your pond each week. It you are using plant compost or plant material, keep the crib tilled to the water line.
91. To make your big fish grow more quickly, you must also feed them other kinds of food. You can feed them
· tender leaves and waste of banana and cassava
· grain mill sweepings
· rice bran
· beer wastes
· cottonseed or groundnut cake
· slaughterhouse wastes
· animal wastes
· kitchen wastes
· spoiled fruit and vegetables
· left- over food
· chopped grass.
92. With your old small pond, you fed your fish only once a day. But your fish will eat better and grow faster if you feed them two or three times during the day.
93. Prepare all the food for one day's feeding at the same time and give the fish part of the food at two or three different times during the day.
94. Always try 10 feed your fish at the same times every day.
Feed the fish at the same time
95. The bigger your fish grow, the more food they will need. If your pond has 450 fish in it, feed them
· 500 to 900 grams of food every day during the first month
· 900 to 1 200 grams of food every day during the second month
· 1 200 to 1 600 grams of food every day during the third month
· 1 600 to 2 000 grams of food every day during the fourth month
· 2 000 to 2 700 grams of food every day during the fifth month
· 2 700 to 3 500 grams of food every day during the sixth month and until the time that you harvest your fish.
96. It is not easy to know exactly how much food to feed your fish. You must watch them when they eat to learn how much food they need.
97. Feed your fish in the shallow part of the pond so that you can see them eat.
98. If you see that the fish do not eat all of their food, give them a little less the next day.
99. If you see that the fish eat all of their food quickly, give them a little more the next day.
100. If you feed your fish at the same place every day, you will see whether the fish are eating well. If you give them too much, the food which is not eaten will stay on the bottom.
101. Too much uneaten food on the bottom of the pond will take the air out of the water.
102. To make it easier to see if your fish are eating well, mark several places in your pond to feed them.
103. Mark each place by making a square or a ring of light wood or bamboo. Drive a pole into the pond bottom and attach the square or ring, as shown in the drawing.
Attach the square
104. When you feed the fish, put the food inside the square or ring. You may be able to see any uneaten food on the bottom under the square or ring. If you cannot see the bottom, feel with your hands to find any uneaten food that may be there.
