How to obtain it. 231 



very well. Another very good plan is to separate the particles by 

 decanting. To do this, a glass jar such as one sees in the window 

 of a confectioner's shop is useful. It possesses the great advantage 

 of transparency, so that an operator may see what he is doing, 

 otherwise it is very easy to pour out a quantity of the settlings 

 which should be carefully avoided. 



Having selected a jar that will hold about a gallon, put a 

 pound of grated liver into it and fill with water, then stir until 

 well mixed. Allow a moment or two for the coarser particles to 

 settle, and pour off the liquid as far as can be done without letting 

 the larger pieces go over. Then add more water to that which is 

 left in the jar, and stir again. A second lot may now be poured 

 off, and the remainder may be thrown to the yearling fish, or, if 

 desired, chopped up again until another lot can be taken out of it 

 for the fry. The liquid that has been decanted may now, with the 

 help of a funnel, be put into pint bottles, and from these fed to 

 the young fish. The process is quite easy, all that is necessary at 

 first being to pour a quantity of the liquid into each rearing box 

 at the head where the water comes in, and watch the result. In 

 the first place the liquid is thoroughly disintegrated by the in- 

 flowing current, and the minute particles of food are hurried 

 along by the current, and the fry will soon be observed to be taking 

 them. 



If the fish be well up towards the head of the box it may not 

 be necessary to feed elsewhere, but should they be very much 

 scattered through its length some of the liquid should be poured 

 in lower down. By all means take care that all the fish have a 

 chance of getting some of this food, if they have any desire for 

 it. It is a great point to get the fish well up to the head of a box 

 whenever possible, but sometimes it is not easy. If they will not 

 come to the food, the food must go to them, or the result will be 

 serious. A great deal of care is required in the early feeding, as \ 

 much depends upon it. A novice will find a good deal of practice \ 

 and skill is required, and also that there is a good field for observa- 

 tion, and that much may be learnt that way. An expert will go 

 through a large hatchery, bottle in hand, and feed the fish in a 

 large number of boxes in a comparatively short time, taking a 

 number of boxes in hand at once, and going over them several
