Moving your baby fish

71. After about three months, there will be many baby fish of different sizes in your pond. Then you can begin to take baby fish out of your nursery pond to put into your big pond.

72. Use baby fish which are 5 centimetres or longer to put into your big pond. If there are many baby fish which are 5 centimetres or longer, choose the biggest ones to put into your big pond.

73. The easiest way to take out your baby fish is to use a seine net. If you use a seine net with a mesh size of about 1 centimetre the smaller fish will swim through and you will catch the fish of 5 centimetres or longer. But be sure to put me fully grown fish back In your nursery pond.

74. From now on, you can take baby fish out of your nursery pond each month for your own use or to sell.

75. Be careful that your nursery pond does not become too full of fish. If there are too many fish, they will not grow well and your baby fish will not be strong and healthy.

76. To keep your nursery pond from becoming too full of fish, drain all of the water out of the pond each year and collect all of the fish.

77. You can eat the big fish that were in the nursery pond. Item 144 in this booklet will tell you what to do with the baby fish.

78. Wait until the bottom of the nursery pond is dry, then clean and repair the bottom and the banks. Items 145 to 148 in this booklet will tell you how.

79. Now fill the nursery pond with water and fertilize it as you did before. When the water is green, put in the right number of fully grown female fish and male fish. Items 56 to 58 in this booklet will tell you how many fully grown fish to use.
