Growing fish all year round

96. Now that you have several fish- ponds, you can grow fish all year round.

97. If you put baby fish in different ponds at different times, you will harvest them at different times. This way, you will not harvest too many fish at the same time and you can harvest fish all year round.

Harvest fish all the year

98. If you have three ponds and a good supply of baby fish, you can stock each pond in a different month of the year and harvest each pond six months later. The diagram on the next page will show you how to harvest and stock three ponds.

99. If you need help, your extension agent or fishery officer will be able to give you good advice on when to put in the baby fish and when to harvest them.

Take advice from extension agent or fishery officer
