Movement, Home Range and Site Fidelity of the Weedy Seadragon Phyllopteryx taeniolatus (Teleostei: Syngnathidae)

Abstract

We measured for the first time movement, home range and site fidelity of the protected and endemic Australian fish weedy seadragon Phyllopteryx taeniolatus. Ninety-two individuals were identified using visual implant fluorescent elastomer and studied over a one-year period. Identified animals remained at the same site over the year within limited home ranges. These home ranges and the movement patterns recorded were independent of sex although movement to shallow sheltered waters to hatch the young was observed at the end of the breeding season for some pregnant males. The site fidelity and restricted home range of the weedy seadragon, as well as the reproduction-related movement have implications for effective management of this protected species.
