It is only within a very recent period, that the science o£ 
fish culture has become known, so as to be o£ practical use 
for the multiplication of our food fishes, although the 
keeping and feeding of fish in artificial ponds and basins 
has long been practiced, and wealthy Eoman citizens in 
ancient times, did not consider their establishment complete 
without their fish stews, to keep up a constant supply for 
the table. According to Diodorus Siculus, fabulous returns 
were realised from Lake Moeris, in Egypt, an artificial 
fish-pond, constructed by the predecessor, of Sesostris. 
Oysters were successfully cultivated in Lake Avernus, near 
Naples, a reservoir since dried up by volcanic upheaval, 
and afterwards at Lake Eusaro, where the industry has 
been continued to the present day. The artificial care of 
eels and other fish, has been pursued successfully near 
Venice, at a lagoon about 140 miles in circumference, 
called Comacchio, where very extensive works have been 
constructed, and arrangements made, for the care of eels
