This paper presents the results of a comparative study of five osteological complexes, the infraorbital bones, branchial arches, urohyal bone, interdigitation of the median fins, and the caudal fin skeleton, of some members of the fish family Tripterygiidae. Osteological characters that may prove valuable for taxonomic purposes are described, and on the basis of the material handled, their use to separate species within the family is discussed. Several formulae were developed for the distribution of the osteological complexes of the dorsal fin, dorsal and ventral caudal procurrent ray distribution, and caudal fin in the different tripterygiid species studied.

The incidence of severe consecutive repetition of lordosis-kyphosis involving three flexions was reported in a specimen of the atherinid fish Atherina boyeri Risso. The values for the angles lay between the lines passing through the sides of the vertebral column and enclosing the curvatures, and the depth of the curvatures of the angles was obtained. Also, the ratio of the vertebral column to the fish total length of deformed and normal specimens of this species was calculated. Possible causes for these anomalies are discussed. © 2017 Archives of Polish Fisheries.

Variation in the numbers of pectoral fin spines and rays, pelvic fin rays, gill rakers on the first gill arch, anal fin rays, and the number of vertebrae of Silurus triostegus Heckel were examined in specimens from 16 localities that span its entire distribution range in the Tigris, Euphrates, and Shatt al-Arab rivers in Iraq. The mean number of the six meristic traits increases toward high latitudes with maximum and minimum values in the north and south of Iraq. Based on cluster analysis and PCA, the Mesopotamian river samples were clearly separated into three distinct groups. The upper Tigris populations were isolated from those of the middle and southern populations of this river and from those of the Euphrates River. Possible reasons for such differentiation among populations are discussed, and the integration of research on this species among the countries neighboring Iraq is required. © Archives of Polish Fisheries 2017.

The first record of a single specimen of alligator gar, Atractosteus spatula (Lacepède, 1803), native to North America, is reported from the inland waters of Iraq. The specimen was caught from southern reaches of the Shatt al-Arab River at Om-al-Rasas Island, Basrah, Iraq during an ichthyologic survey in September 2016 using gillnets with mesh size of 40 mm. The capture of a sub-adult specimen, 900 mm in total length, marks the first record of a member of the family Lepisosteidae in the freshwater system of Iraq. Aquarium trade pathway is the suspected factor for the presence of this species in the Iraqi freshwater area. © 2017, Scientific Society of Szczecin. All rights reserved.

Vertebral deformities are reported in fivebeard rockling Ciliata mustela (Lotidae) collected from Masfjorden, Western Norway. Four abdominal and four caudal vertebrae were involved in the anomalies. A hyperostotic haemal spine was observed. In addition, other minor anomalies were noticed in the abnormal specimen. It is possible that either genetic and/or epigenetic factors may have been implicated in this anomaly. © 2016 Senckenberg Gesellschaft für Naturforschung and Springer-Verlag Berlin Heidelberg

Seven osteological characters of the axial skeleton are studied in the eight species of the genus Pampus. The characters include: pattern of interdigitation of the dorsal- and anal-fin pterygiophores with the neural and haemal spines of the vertebrae, structure of the vertebral column, distribution of the dorsal- and ventral- procurrent caudal-fin rays, distribution of the principal caudal-fin rays and the morphology of the caudal-fin skeleton. All these features appear to be useful in the characterization of the eight species of the genus Pampus. Formulae for the structure of the vertebral column, the dorsal- and anal-fin pterygiophores’ interdigitation with the neural and haemal spines of the vertebrae, distribution of the dorsal and ventral procurrent caudal-fin rays, and distribution of the principal caudal-fin rays were developed. Pampus nozawae was recently considered a synonym of P. argenteus. However, according to the characters used in the present study, this species is notably distinct from P. argenteus.

In the present work we describe nine saccular otolith morphometric indices (circularity, rectangularity, aspect ratio, percentage of the otolith surface occupied by the sulcus, percentage of the sulcus length occupied by the cauda length and ostium length, otolith length relative to the length of the fish, rostrum aspect ratio and percentage of the rostrum length occupied by the otolith length) of 41 species of the Tripterygiidae family collected mainly from New Zealand, Australia, Chile, South Africa, Mediterranean Sea and North America. The principal component of analysis showed that the indices that best explain the variability between species were related to sulcus and rostrum morphometry. According to cluster analysis, otolith morphometry could reflect the diversity of microenvironments for some genera such as Notoclinops and Forsterygion, while this does not happen to genera like Enneapterygius and Ruanoho. The discriminant analysis showed that the species Helcogrammoides cunninghami, Karalepis stewarti, Lepidoblennius haplodactylus, Notoclinus compressus, Ucla xenogrammus can be discriminated by using the morphometric indices. Two new indices related to the sulcus that were of great value for the discrimination of these species are described for the first time. This information will be a useful tool for palaeontological, taxonomic and trophic ecology studies. Copyright © Marine Biological Association of the United Kingdom 2015


Asymmetry analysis was carried out for three bilateral characters of two cichlid fish species, Sarotherodon melanotheron and Coptodon guineensis collected from two localities, Lake Ahémé and Porto-Novo lagoon, Republic of Bénin, West Africa. For both S. melanotheron and C. guineensis snout length (SL), eye diameter (ED) and number of scales on lateral line (LLS), bilateral asymmetry was higher in the fish specimens collected from Porto-Novo lagoon compared with that of specimens from Lake Ahémé. Bilateral asymmetry in S. melanotheron and C. guineensis increased with the fish size at all localities. The possible causes of bilateral asymmetry in the two cichlid species are discussed in relation to different pollutants in both water bodies. © 2016 Elsevier Ltd.
