Spatial ecology of shark-like batoids in a large coastal embayment

摘要: Understanding how spatial ecology varies between life stages, and whether there is an overlap of critical areas (e.g., nursery areas, breeding sites), may provide significant benefits to conservation planning. The present work examined the space use residency shark-like batoids (families Rhynchobatidae Rhinobatidae) in a nearshore system. An array 63 acoustic receivers deployed Cleveland Bay, north Queensland, Australia, passively tracked 15 G. typus 20 Rhynchobatus spp. 2009 2011. Glaucostegus were monitored 1 766 days (mean = 333 ± 69 days) site from 198 73 25 days). Both adult male female exhibited philopatric behaviour patterns, leaving bay returning after periods about 9–12 months same where they detected previous years. Individuals with lower had larger activity spaces. for 707 231 50 350 82 24 no synchronicity bay. changed size individuals, comparison effect on study improves our understanding batoid waters useful information management these populations.
