A trap was designed for providing quantitative samples of freeswimming animals in marshes and shallow ponds. The device consists of netting tied to an aluminum frame with attachments for rapidly raising the net and entrapped organisms out of the water. Collections from a series of pull—up traps, operated monthly in Everglades National Park, provide an index of fluctuations in aquatic animal populations.
