AMATEUE FISH CULTURE 



best method is to let the pond down as low as pos- 

 sible, and then to plant some weeds round the 

 margin ; the water is then allowed to gradually 

 fill up the pond, and as it rises weeds are planted 

 round the rising margin of the water. In ponds 

 which cannot be emptied at all, or not sufficiently 

 to carry out this plan, weeds may be planted in an 

 easy but not quite so effectual a manner. They 

 may be planted in shallow baskets containing 

 some mud from the bottom of the pond, and then 

 lowered in suitable places from a boat, or bundles 

 of the weed may be tied to stones and dropped 

 into the water in a similar manner. 



These latter methods are, of course, not so good 

 as actually planting the weeds round the advanc- 

 ing margin of the water, for success depends to a 

 certain extent upon chance. Some of the weeds 

 thus planted are, however, sure to take root and 

 grow. Plants of different kinds, of course, are 

 necessary at different depths and on different 

 kinds of bottoms, and good kinds are necessary at 

 the margin of the water as well. I give a list of 

 some suitable plants of each kind at the end of 

 this chapter. 



Similar methods are used in planting weeds in 

 rivers and streams to those used in ponds. If the
