Tagging Methods

Telemetry is useful for monitoring rare and threatened species if they can be effectively tagged. Relatively abundant, closely related species are sometimes used as surrogates in refining tagging methods or testing the suitability of methods before transfer to rare and threatened species. A decision framework for developing a radio-tagging method of an endangered fish (Macquaria australasica; Percichthyidae) is presented based on experiences with tagging a closely related, surrogate species (Macquaria ambigua). Aquaria and field-based trials demonstrated the suitability of internally implanting a radio-tag with an externally exited antenna on the surrogate species. However, transferring this method to the endangered species under field conditions was unsuccessful in terms of mortality and/or radio-tag rejection. In this case, a surrogate species served to refine radio-tagging methods, but did not successfully indicate the suitability of these methods for a closely related species. This cautionary tale illustrates that surrogate species are not always effective and extrapolation of methods, even across closely related species, may be perilous.

Species Rarity

Radio-tracking provides an effective means of studying the spatial ecology of threatened fishes where almost inaccessible habitats and species rarity render conventional mark–recapture methods impractical. Initially, validation of an effective radio-tagging method is required; in the present study, an aquaria trial based on nine hatchery-reared, adult male Maccullochella maquariensis (Percichthyidae) was conducted. Fish resumed feeding within days of being internally implanted with a radio-tag, and tag rejection was not observed (0%, n = 9) based on a 2-month observational period. Following release into an upland stream, individual-specific movements resulted in upstream (n = 1) and downstream (n = 6) dispersal as well as fidelity to the release site (n = 2) at the completion of the study. Individuals established small home-ranges (mean length of river used by an individual per diel period ranged from 47 to 292 m) and were most active in the early morning and evening (n = 6). Complete survivorship of individuals bearing active radio-transmitters (n = 8) was recorded up until 4 months after release. However, an estimated zero or one individual was alive when the last active radio-tag expired 11 months after release (n = 8). The present study highlights the use of radio-tracking in monitoring the dispersal and survivorship of small numbers of hatchery-reared threatened fish released into natural habitats as part of species re-introduction programs.
