and what is probably of more use, large establishments are being 
erected for pisciculture. This branch of industry is not new. 
The Chinese have pursued it from time immemorial, and the 
Romans bred fish, partly for amusement, and partly to supply 
their tables. There is but one method. Reservoirs are built near 
the shore, so that the waters of the high tides can sweep into 
them ; in these tanks the fish are kept, looked after, fed, and 
preserved, precisely as we do with our cattle. 
GENERAL VIEW OF THE PISCICULTURE ESTABLISHMENT AT HUNINGUE. 
There are many of these establishments upon the French 
coast, and we are slowly following the good example. As 
yet our attention is chiefly turned to salmon and trout culture. 
Already the attempts have been crowned with great success, and 
we have been enabled to increase the number of river fish 
materially ; besides stocking the rivers of New Zealand and 
Australia. This idea of preserving and watching over the hatching 
of the eggs of salmon and trout, dates back to the middle of the 
seventeenth century.
