Abstract

A new technique is described for remote monitoring of aquatic invertebrate populations which was specifically designed to eliminate effects on organism behavior attendant with other surveillance systems. Specifically, the system described overcomes the necessity for surgical implantation, restrictive weight, and the generation of unnatural activity.

Activities of a wide variety of aquatic invertebrates have been monitored using this system ranging in size from crustaceans of 300–600 μ long to dragonfly naiads of 3–5 cm long.

Immature Anax sp. and Somatochlora sp. were monitored for respiratory activity in relationship to decreasing oxygen tensions. An inverse relationship was observed between respiratory frequency and amplitude of respiration.
