Gerres species play significant roles in marine fishery, but its evolution has received little attention. To date, only two Gerres mitochondrial genomes were reported. In the present study, three mitogenomes of Gerres (Gerres filamentosus, Gerres erythrourus, and Gerres decacanthus) were systemically investigated.

In examinations of 12 639 specimens of 187 species of Venezuelan fishes, the authors found 10 species in three families of isopods (Gnathiids, Gnathia spp. from Diplectrum radiale*, Heteropriacanthus cruentatus*, Orthopristis ruber* and Trachinotus carolinus*; two aegids, Rocinela signata from Dasyatis guttata*, H. cruentatus*, Haemulon auro- lineatum*, H. steindachneri* and O. ruber; and Rocinela sp. from Epinephelus flavolimbatus*; five cymothoids: Anilocra haemuli from Haemulon boschmae*, H. flavolineatum* and H. steindachneri*; Anilocra cf haemuli from Heteropriacanthus cruentatus*; Haemulon bonariense*, O. ruber*, Cymothoa excisa in H. cruentatus*; Cymothoa oestrum in Chloroscombrus chrysurus, H. cruentatus* and Priacanthus arenatus; Cymothoa sp. in O. ruber; Livoneca sp. from H. cruentatus*; and Nerocila fluviatilis from H. cruentatus* and P. arenatus*).

  • Sequence Data on Four Genes Suggest Nominal Gerres Filamentosus Specimens from Nayband National Park in the Persian Gulf Represent Two Distinct Species
    Iranian Journal of Animal Biosystematics (IJAB) Vol.6, No.2, 1-11, 2010 ISSN: 1735-434X Sequence data on four genes suggest nominal Gerres filamentosus specimens from Nayband National Park in the Persian Gulf represent two distinct species a a,b,c b d Asgharian, H. , Elahi, E. * , Kalirad, A. , Hosseinzadeh Sahafi, H. aDepartment of Biotechnology, College of Science, University of Tehran, Tehran, Iran. b School of Biology, College of Science, University of Tehran, Tehran, Iran. c Center of Excellence in Biomathematics, School of Mathematics, Statistics and Computer Science, College of Science, University of Tehran, Tehran, Iran. Sequence data of a recent COI barcoding study on fish from the Nayband National Park in the Persian Gulf showed relatively high sequence divergence among nominal Gerres filamentosus specimens. The sequences grouped into two clusters, signaling the possible existence of cryptic species. The clustering pattern was corroborated by results of 16S rDNA sequencing. We investigated the hypothesis that G. filamentosus specimens represent cryptic species by inspecting sequences of Cyt b, an additional mitochondrial gene, and 28S rDNA a well-conserved nuclear marker. Based on sequence data of four genes (COI, 16S rDNA, 28S rDNA and Cyt b), we propose that nominal Gerres filamentosus specimens from Nayband National Park represent a species complex comprising two distinct but closely related species. The observation of a large deletion in the highly conserved 28S rDNA gene of a representative specimen of one of the G. filamentosus clusters was considered particularly informative. G. filamentosus occurs through vast ranges of the Indo-Pacific, from the east coast of Africa to Japan and Australia.

Piscat. 45 (4): 393–401. Background. The Lacandon mojarra, Eugerres castroaguirrei González-Acosta et Rodiles-Hernández, 2013, was described from the Grijalva–Usumacinta River basin (Mexico). According to the diagnosis E. castroaguirrei differs from the only other freshwater Gerreidae, the Mexican mojarra, Eugerres mexicanus (Steindachner, 1863) by the combination of certain morphological characters. However, a comparison of materials obtained in the Usu- macinta River, besides of type materials and other preserved specimens, yielded contradictory results. Therefore, the objective of this paper was to clearly determine if E. mexicanus and E. castroaguirrei are subjective synonyms applying morphological and molecular analyses. Materials and methods.

  • Batch Fecundity of the Japanese Silver-Biddy Gerres Equulus in the Yatsushiro Sea, Western Kyushu, Japan
    Aquaculture Sci. 56（3），409－413（2008） Batch Fecundity of the Japanese Silver-biddy Gerres equulus in the Yatsushiro Sea, Western Kyushu, Japan 1 2, ＊ 2 2 Khan M. IQBAL , Hiroshi SUZUKI , Jun OHTOMI and Yasuji MASUDA Abstract: The Japanese silver-biddy Gerres equulus (Temminck and Schlegel) is one of the most common shore fishes in the costal waters of southern Japan and commercially important for the local fishery. The batch fecundity of G. equulus was examined from the specimens collected in the Yatsushiro Sea, western Kyushu, Japan in June-September, 2001 and 2002. Batch fecundity (BF) ranged from 15,083 to 92,356. The regression correlation between BF and standard length (SL) for the early and the late spawning period was significantly different and these regressions were expressed as BF＝1.00×10－4 SL3.79 (early spawning period) and BF＝1.30×10－4 SL3.33 (late spawning period), respectively. The BF of females at age 2-10 years was higher in the early spawning period than in the late spawning period. Key words: Gerres equulus; Japanese silver-biddy; Batch fecundity; Yatsushiro Sea Fishes belonging to the family Gerreidae the histological studies suggested that the spawn- are widely distributed in the tropical and sub- ing season of G. equulus continued from June to tropical waters in many parts of the world and September (Iqbal et al. 2007). According to Iqbal typically spawn throughout the year, with one or et al (2007), female G. equulus attained sexual more spawning peak periods (Araujo and Santos maturity at a minimum size of 141 mm standard 1999; Cyrus and Blaber 1984; Sarre et al.
