    Gerlach et al. Frontiers in Zoology (2016) 13:13 DOI 10.1186/s12983-016-0145-1 RESEARCH Open Access Fluorescence characterisation and visual ecology of pseudocheilinid wrasses Tobias Gerlach1*, Jennifer Theobald1, Nathan S. Hart2, Shaun P. Collin2 and Nico K. Michiels1 Abstract Background: Wrasses represent the second largest family of marine fishes and display a high diversity of complex colours linked to ecological functions. Recently, red autofluorescent body colouration has been reported in some of these fishes. However, little is known about the distribution of such fluorescent body patterns in wrasses or the animals’ ability to perceive such colours. Results: Against this background, we (1) investigated long-wavelength emission autofluorescence in thirteen species of pseudocheilinid wrasses and (2) characterised the spectral absorbance of visual pigments in one of the examined species, the fairy wrasse Cirrhilabrus solorensis. Spectrophotometric analysis revealed that fluorescent body colouration is widespread and diverse within this clade, with considerable variation in both fluorescent pattern and maximum emission wavelength between species. Characterisation of visual pigments in retinal photoreceptors showed a single class of rod and three spectrally distinct cone photoreceptors, suggesting possible trichromacy. Conclusion: Combining the emission characteristics of fluorescence body colouration and the spectral sensitivity data of retinal cells suggests that the visual system of C. solorensis is sensitive to pseudocheilinid fluorescence. Keywords: Red fluorescence, Photoluminescence, Microspectrophotometry, Colour vision, Labridae Background wavelength (>600 nm) part of downwelling sunlight is Wrasses (Labridae) represent the second largest marine quickly absorbed by sea water, which is most transparent fish family, containing more than 600 species within 82 to blue light of wavelengths at around 480 nm [15–17].

Abstract A checklist of shallow (to 60 m depth) reef fishes is provided for the Bird’s Head Peninsula region of West Papua, Indonesia. The area, which occupies the extreme western end of New Guinea, contains the world’s most diverse assemblage of coral reef fishes. The current checklist, which includes both historical records and recent survey results, includes 1,511 species in 451 genera and 111 families. Respective species totals for the three main coral reef areas – Raja Ampat Islands, Fakfak-Kaimana coast, and Cenderawasih Bay – are 1320, 995, and 877. In addition to its extraordinary species diversity, the region exhibits a remarkable level of endemism considering its relatively small area. A total of 26 species in 14 families are currently considered to be confined to the region. Introduction and finally a complex geologic past highlighted The region consisting of eastern Indonesia, East by shifting island arcs, oceanic plate collisions, Timor, Sabah, Philippines, Papua New Guinea, and widely fluctuating sea levels (Polhemus and the Solomon Islands is the global centre of 2007). reef fish diversity (Allen 2008).

Fisheries Occasional Publications No. 80, September 2010. ISSN: 1447 - 2058 ISBN: 1 921258 90 X Information about this guide he intention of the North Coast Fish Identification Guide is to provide a simple, Teasy to use manual to assist commercial, recreational, charter and customary fishers to identify the most commonly caught marine finfish species in the North Coast Bioregion. This guide is not intended to be a comprehensive taxonomic fish ID guide for all species. It is anticipated that this guide will assist fishers in providing a more comprehensive species level description of their catch and hence assist scientists and managers in understanding any variation in the species composition of catches over both spatial and temporal scales. Fish taxonomy is a dynamic and evolving field. Advances in molecular analytical techniques are resolving many of the relationships and inter-relationships among species, genera and families of fishes. In this guide, we have used and adopted the latest taxonomic nomenclature. Any changes to fish taxonomy will be updated and revised in subsequent editions. The North Coast Bioregion extends from the Ashburton River near Onslow to the Northern Territory border. Within this region there is a diverse range of habitats from mangrove creeks, rivers, offshore islands, coral reef systems to continental shelf and slope waters.

  • Aquarium Fish Fishery Commercial Fishing Rules in Queensland
    Aquarium fish fishery Commercial fishing rules in Queensland From 1 September 2021, the aquarium fish fishery will be managed under the Queensland marine aquarium fish fishery harvest strategy. General • The aquarium fishery is managed at a species level and risks to stocks identified through ecological risk assessments. • The following species have been identified as Tier 1 species (moderate or high level of ecological risk, or no-take recreational species) in the harvest strategy: o scalloped hammerhead shark (Sphyrna lewini) o wideband anemonefish (Amphiprion latezonatus) o great hammerhead shark (Sphyrna mokaran) o blackback anemonefish (Amphiprion melanopus) o smooth hammerhead shark (Sphyrna zygaena) o ocellaris clownfish (Amphiprion ocellaris) o wedgefish (family Rhinidae) o orange clownfish (Amphiprion percula) o giant guitarfish (family Glaucostegidae) o harlequin tuskfish (Choerodon fasciatus) o shortfin mako shark (Isurus oxyrinchus) o pineapplefish (Cleidopus gloriamaris) o longfin mako shark (Isurus paucus) o blue tang (Paracanthurus hepatus) o barramundi cod (Chromileptes altivelis) o scribbled angelfish (Chaetodontoplus duboulayi) o humphead Maori wrasse (Cheilinus undulatus o Queensland yellowtail angelfish (Chaetodontoplus undulates) meredithi) o paddletail (Lutjanus gibbus) o Queensland groper (Epinephelus lanceolatus) o potato rockcod (Epinephelus tukula) o sawfish (family Pristidae). • All other species caught within the fishery (all non-Tier 1 species) have been identified as Tier 2 species (acceptable level of ecological risk) in the harvest strategy. • No catch limits are in place for this fishery; however, all species will be monitored and harvest strategy decision rules applied depending on changes in catch rates. • Measurements of vessels used in commercial fisheries are determined by national marine safety requirements under the National Standard for Commercial Vessels – for more information, visit amsa.gov.au.

E-mail: [email protected] 3Ichthyology, Australian Museum, 1 William Street, Sydney, New South Wales 2010, Australia 4Corresponding author Abstract Cirrhilabrus shutmani, new species, is described on the basis of four specimens from Didicas Volcano, Babuyan Islands, Cagayan province, northern Philippines. The holotype and three paratypes were collected at a depth of 50–70 m, along denuded rubble slopes. The new species belong to a complex consisting of C. blatteus, C. claire, C. earlei, C. jordani, C. lanceolatus, C. roseafascia, C. rubrisquamis and C. sanguineus. Aside from similar nuptial male colouration, the nine spe- cies share the following character combination: relatively short pelvic fins (not or barely reaching anal-fin origin, except for C. claire with relatively long pelvic fins); a pair of stripes on head (in both sexes); and, dorsal and anal fins without obvious stripes or spots. It differs from the other members of its group in lacking any stripes on the upper and lower body, and in having the following live colouration details: upper part of nape dusky red; dorsal and anal fin bright red with dusky markings; pelvic fins bright red, dusky anteriorly; caudal fin bright yellow basally with distal half bright red.

  • Cirrhilabrus Greeni, a New Species of Wrasse (Pisces: Labridae) from the Timor Sea, Northern Australia
    Cirrhilabrus greeni, a new species of wrasse (Pisces: Labridae) from the Timor Sea, northern Australia GERALD R. ALLEN Department of Aquatic Zoology, Western Australian Museum, Locked Bag 49, Welshpool DC, Perth, Western Australia 6986, Australia E-mail: [email protected] MICHAEL P. HAMMER Natural Sciences, Museum and Art Gallery of the Northern Territory, PO Box 4646, Darwin, NT 0801, Australia E-mail: [email protected] Abstract A new species of labrid fish, the Sunset Fairy-wrasse,Cirrhilabrus greeni n. sp., is described from seven specimens, 39.4–47.3 mm SL, collected from the eastern Timor Sea, Northern Territory, Australia. The species is clearly distinguished by its terminal-phase male color pattern, consisting of pink to reddish hues on the upper half of the head and body and yellow on the lower half, in combination with a mainly yellow-orange dorsal fin and a scarlet- red anal fin. The caudal fin of the male is particularly distinctive, being emarginate but appearing lunate due to a clear central portion and tapering red bands along dorsal and ventral margins. Females can be distinguished from sympatric congeners by having a large black spot on the upper caudal peduncle. Sequencing of the mtDNA- barcode marker COI reveals that the new species has identical sequences to C. rubripinnis and C. aff. tonozukai from the Philippines, which have very different color patterns and tail shapes from the new species, indicating the new species has diverged recently and/or there is historic or episodic hybridization within the species complex. Key words: taxonomy, systematics, ichthyology, coral-reef fishes, Indo-Pacific Ocean, fairy wrasse, DNA barcoding.
