Description
English: Troughs for Rearing Mussels

In troughs supplied with naturally clarified water flowing from near the surface of one of the ponds, the best conditions have been found for rearing several species of fresh-water mussels. As is the fortune of experimental work, success has been variable, but a single trough may produce in one season more than 2,000 young mussels one-fourth to one-half inch in length
