A nursery pond
18. With bigger ponds or more ponds, you must be sure that you have a supply of baby fish all year round.
19. If you have two or three big ponds that together have an area of more than 500 square metres (one 10 x 10 metre pond + two 15 x 15 metre ponds = 550 square metres), you should have your own nursery pond.
20. If you do not already have a nursery pond, Booklet No. 30, Items 43 to 88, will tell you how to build one, how to care for the baby fish and what to do with them.
