“…Results from this study indicate the bias of females towards smaller lengths and of males towards larger ones as already reported for other scorpaenid species such as Scorpaena maderensis Valenciennes, 1833 (see La Mesa et al 2005), Scorpaena loppei Cadenat, 1943 (see Ordines et al 2012), Pontinus kuhlii (Bowdich, 1825) (see Paiva et al 2013), Helicolenus dactylopterus (Delaroche, 1809) (see Massuti et al 2000), and also for Scorpaena notata of Balearic Islands (Ordines et al 2009). The reproductive strategy showed by several species within the scorpaenid family such as the development of a gelatinous matrix within the ovary (Muñoz 2010) imply that females have a higher energetic cost during reproduction than males and can justify the growth differences between sexes.…”

“…The reproductive strategy showed by several species within the scorpaenid family such as the development of a gelatinous matrix within the ovary (Muñoz 2010) imply that females have a higher energetic cost during reproduction than males and can justify the growth differences between sexes. Despite this length class bias, the majority of the published works showed no deviation from an overall sex ratio of 1 : 1 (Massutí et al 2000, Ordines et al 2009, 2012, Sequeira et al 2009. Curiously, for the small red scorpionfish, Scarcella et al (2011) and Muñoz et al (2005) reported a sex ratio biased in favour of males but no significant differences in length classes by sex.…”

“…However, for S. loppei there is no sequence data currently available in BOLD nor in GenBank. Furthermore, the whole group is challenging from the viewpoint of identification [46] . Considering only the temperate North East Atlantic, there are 8 additional species reported [21] not included here ( Scorpaena azorica, Scorpaena canariensis, Scorpaena elongata, Scorpaena laevis, Scorpaena maderensis, Scorpaena plumieri, Scorpaena porcus, Scorpaena stephanica ), with only 3 of them having sequence data available in BOLD (data not shown).…”

DNA Barcoding for Species Assignment: The Case of Mediterranean Marine Fishes

et al. 2014

BackgroundDNA barcoding enhances the prospects for species-level identifications globally using a standardized and authenticated DNA-based approach. Reference libraries comprising validated DNA barcodes (COI) constitute robust datasets for testing query sequences, providing considerable utility to identify marine fish and other organisms. Here we test the feasibility of using DNA barcoding to assign species to tissue samples from fish collected in the central Mediterranean Sea, a major contributor to the European marine ichthyofaunal diversity.Methodology/Principal FindingsA dataset of 1278 DNA barcodes, representing 218 marine fish species, was used to test the utility of DNA barcodes to assign species from query sequences. We tested query sequences against 1) a reference library of ranked DNA barcodes from the neighbouring North East Atlantic, and 2) the public databases BOLD and GenBank. In the first case, a reference library comprising DNA barcodes with reliability grades for 146 fish species was used as diagnostic dataset to screen 486 query DNA sequences from fish specimens collected in the central basin of the Mediterranean Sea. Of all query sequences suitable for comparisons 98% were unambiguously confirmed through complete match with reference DNA barcodes. In the second case, it was possible to assign species to 83% (BOLD-IDS) and 72% (GenBank) of the sequences from the Mediterranean. Relatively high intraspecific genetic distances were found in 7 species (2.2%–18.74%), most of them of high commercial relevance, suggesting possible cryptic species.Conclusion/SignificanceWe emphasize the discriminatory power of COI barcodes and their application to cases requiring species level resolution starting from query sequences. Results highlight the value of public reference libraries of reliability grade-annotated DNA barcodes, to identify species from different geographical origins. The ability to assign species with high precision from DNA samples of disparate quality and origin has major utility in several fields, from fisheries and conservation programs to control of fish products authenticity.

“…Native Mediterranean fish species of the Scorpanidae family exhibit several ecological similarities with P. miles, such as from being a generalist to a specialist strategy at a local level. For instance, Scorpaena maderensis Valenciennes, 1833 prefers epibenthic crustaceans [58], and Scorpaena loppei Cadenat, 1943 prefers mysids and decapods [59]. Studies regarding the feeding ecology of S. porcus, showed similar specialist feeding strategies [60][61][62][63], and in some cases, endangered seahorse species were preyed upon [64].…”

The diet of the lionfish (Pterois miles), an invasive species in the Aegean Sea, was examined by collecting stomach content data from fish collected in three study sites in the Aegean Sea (southern Crete, Kastellorizo, and Nysiros islands). Prey composition in terms of numerical abundance and frequency of occurrence was used to compare lionfish’s diet between these sites. Lionfish largely preyed upon teleosts (4% to 83% numerical abundance and 16% to 58% frequency of occurrence, depending on the site) and decapods (12% to 95% numerical abundance and 11% to 81% frequency of occurrence). The most important teleost families in lionfish’s diet were Gobiidae, Labridae, and Scorpaenidae, while decapods and especially the family Scyllaridae and the genus Plesionika were the dominant decapod prey items. The lionfish was found to be an especially successful generalist across the study sites, an opportunistic, predatory species overall, and at the same time, at a local level, it seems to be an equally successful specialist that could increase the predation mortality of already stressed prey populations and can be a serious threat to endemic, critically endangered, and/or commercially important species.
