It may be necessary, however, to continue to apply fertilizer to the pond at short intervals. The collecting of entomostraca from reservoirs and lakes for the newly-hatched fish in the cement ponds is an important part of the work and occupies the time of many people. The peculiar bag-net required for this purpose is 25 to 30 feet long and 2.5 feet wide throughout its length, the bottom being cut off square and gathered with a string; it is made of fine cotton or calico that has been treated with extract of oak bark or other astringent solution.

The separation of the crustaceans into sizes adapted for the different sizes of the fry is accomplished by means of sieves, of which 5 sizes are used, having respectively 130 meshes, 100 meshes, 80 meshes, 60 meshes, and 20 meshes to the inch. The sieves are 10 to 15 inches in diameter, and have either wire or cloth bottoms.
