AMATEUE FISH CULTUEE 



March, the amateur is, at the time he receives 

 the eyed ova, quite safe from frost. 



The best method to pursue is to make long 

 narrow ponds, with a current running through 

 them, and to hatch the eggs out in trays and 

 boxes suspended in these ponds. "When the 

 young fish hatch out, the trays which contained 

 the ova can be removed, and the young fish kept 

 in the boxes. Later on the young fish can be 

 released from the boxes into the ponds. I shall 

 subsequently describe how these ponds, trays, 

 and boxes should be made. 



The rearing ponds should be made, if possible, 

 at a fall in the level of the water supply, so that 

 they may be easily emptied. This is an im- 

 portant point which is frequently overlooked by 

 amateurs. There should be an outlet on a level 

 with the bottom of the pond, and if the water 

 escapes through a pipe, that pipe should incline 

 downwards. This, in a series of ponds, of course 

 necessitates the ponds being at different levels, 

 but the water is thus under much better control 

 than if the outlet is at a higher level, and the 

 ponds are easily emptied. Ponds may, however, 

 be worked successfully with the outlet in mid- 

 water, or even near the surface, though this does
