Ontogenetic shift in spectral sensitivity of Pacific snapper Chrysophrys auratus
Electroretinogram (ERG) experiments on the sparid fish Chrysophrys auratus (Forster 1801) demonstrated an ontogenetic shift in spectral sensitivity, from long wavelengths (yellow-orange) in small (60 g) fish, to shorter wavelengths (blue) in larger (800 g) fish. Changes in spectral sensitivity are consistent with the life history of the species, since juveniles migrate from predominantly long w...
متن کاملMovements, Home Range and Site Fidelity of Snapper (Chrysophrys auratus) within a Temperate Marine Protected Area
Understanding the movement dynamics of marine fish provides valuable information that can assist with species management, particularly regarding protection within marine protected areas (MPAs). We performed an acoustic tagging study implemented within the Port Stephens-Great Lakes Marine Park on the mid-north coast of New South Wales, Australia, to assess the movement patterns, home range and d...
متن کاملDecadal Changes in the Abundance and Length of Snapper (Chrysophrys auratus) in Subtropical Marine Sanctuaries
Abundance and length of the highly-targeted snapper Chysophrys auratus were compared between sites in 'no take' areas (Sanctuary Zones: SZ), partial protected areas which are fished (Habitat Protection Zones: HPZ), and areas outside (Outside) the Solitary Islands Marine Park (SIMP), Australia. Baited Remote Underwater Video (BRUV) sampling on shallow rocky reef (15 - 25 m) was conducted annuall...
متن کاملAngling-Induced Barotrauma in Snapper Chrysophrys auratus: Are There Consequences for Reproduction?
In response to concerns regarding the potential for sub-lethal impacts of barotrauma on reproductively active Chrysophrys auratus during catch and release, 90 males and 90 females representing five reproductive stages (immature or resting--28%, developing--8%, developed--7%, ripe or spawning--23% and spent--34%) were angled from 8-70 m and macroscopically assessed (on-board and then in a labora...
