the land. Several pond configurations were observed on the
fish farms visited. Fishponds were built either as a single
pond or as a set of two, three, or four ponds sharing common
levees. The average volume of earth moved varied inversely
with the number of adjacent ponds built. Construction of a
single pond required the movement of an average of about
1,700 cubic yards per acre. Conversely, construction of two,
three, and four ponds sharing common levees averaged
1,550, 1,500, and 1,250 cubic yards per acre, respectively.
