THE CALIFORNIAN SALMON. 
It is stated that a fish eats one-hundredth part of his 
weight daily, and this rule may give some indication of the 
quantity of food to he given. If too much is put in the 
water, hy its decay it becomes a great source of danger to 
the fish. 
THE LIBERATION OE YOUNG EISH. 
Just before the alevins lose their sacs, and while they 
require but little food, is a good time to transport them, 
especially where the distance to their destination is great. 
At this stage they are much more easily carried, than when 
they grow to a considerably larger size, and many think 
that hy being early accustomed to face danger, they are 
more likely to come successfully through the perils they 
have to encounter, than if trained to come for their food, 
and partially domesticated, without having any knowledge 
of the dangers that they must encounter when liberated in 
the open waters. Where salmon can be retained in ponds 
until they attain the smolt stage, and put on their silvery 
coat, preparatory to commencing their migration to the 
sea, and where every care is taken of them, it would, no 
doubt, be more in their favour, and a larger number would 
probably survive, than if they had been exposed to all the 
perils of the river ; but if they had to be transported to a 
distance before being liberated, the risk of loss with fish of 
the size that they would then attain to, would more than 
counterbalance the loss from their early liberation. 
THE TRANSPORT OF LIVE EISH. 
The transport of live fish to long distances has been a 
most difficult problem, until it was discovered that the
