This has been tried many times, but never with any degree of success. If the daphnia pools are too far distant to make collecting practicable it is best to try to inoculate some suitable pond nearby, but there should be no fish in the pond. Daphnia, if not crowded, may be shipped quite a distance. The practical way to raise daphnia for food purposes is described in the chapter on Wholesale Breeding (page 64). A method of carrying live food which is growing in favor is to crate them (without water) in layers in a tin box. Frames about 10 x 12 inches, made of %-in. square wood, are covered on one side with thin muslin. These are floated in the water, the daphnia dropped in, spread out evenly and placed in carrying box, which, of course, needs to be airtight. The. Fig. 126. Carrying Case and Li\'e-Food Trays number of layers is only limited by the depth of the box. Daphnia may be spread to a depth of about y^-mch, but mosquito larvae may be piled to %-inch without injury. This method avoids carrying the great weight of water needed in collecting pails, and, in the experience of the writer, gets a higher percentage of the food home alive. Spread out thinly and in a cool temperature in October they have been kept alive in a moist condition on the rafts in storage for two days. The only disadvantage is the chance that the rafts may blow away while collecting. If the rafts are dried immediately after using and all daph- nia cleaned out from between the fabric and the wood, they will last several seasons. The bottom frame is usually blank, so that the slightly sagging cloth on the one above will have drainage and not stand in the shallow water bound to collect in the bottom of can. The.
