Morphological and Genetic Diversity of Two Forms of Muksun Coregonus muksun (Salmonidae) of the Khatanga River Basin as a Key for Understanding the Phylogenetic Relationships between Muksun and Whitefish C. lavaretus
Journal of Ichthyology - Tập 60 - Trang 909-922 - 2021
E. A. Borovikova, Yu. V. Budin
Morphological analysis of muksun Coregonus muksun of the Khatanga River basin revealed that along with its typical high-density-rakered form, individuals of the low-density-rakered form also live in this region. Analysis of the genetic polymorphism of three marker regions of mitochondrial (ND1 and COI fragments) and nuclear (ITS1) DNA indicates the polyphyletic origin of these forms. The revealed ...... hiện toàn bộ
Unusual record of bluemouth rockfish Helicolenus dactylopterus (Osteichthyes: Scorpaenidae) in Tunis Southern Lagoon (Northern Tunisia, Central Mediterranean)
Journal of Ichthyology - Tập 56 - Trang 620-624 - 2016
K. Ounifi Ben Amor, J. Ben Souissi, C. Capapé, M. M. Ben Amor
The record of bluemouth rockfish Helicolenus dactylopterus (Delaroche, 1809) at low depth suggests that the species is prone to large vertical migrations. This capture confirms the occurrence of the species in the Tunisian waters where it is known as very rare. It confirms also the success of ecological restoration of Tunis Southern Lagoon and the possible establishment of fish populations, mainly...... hiện toàn bộ

Special traits of growth and feeding of the stone sculpin Paracottus knerii (Cottidae) in water bodies of different types
Journal of Ichthyology - Tập 50 - Trang 529-535 - 2010
Yu. P. Tolmacheva, B. E. Bogdanov
Growth and feeding of the stone sculpin Paracottus knerii (Cottidae) is investigated in Water Bodies of Different Types: Baikal (the littoral of its southern part), the Angara River, and the mountainous Sobolinoe Lake (the southern Baikal basin). The highest growth rate is characteristic of the South-Baikalian population, followed by the Angara population. The stone sculpin from Sobolinoe Lake is ...... hiện toàn bộ
First record of Klein’s sole Synapturichthys kleinii (Osteichthyes: Soleidae) off the Syrian coast (eastern Mediterranean)
Journal of Ichthyology - Tập 55 - Trang 918-921 - 2015
M. Ali, A. Saad, M. Fadel, I. Issa, C. Reynaud, C. Capapé
This paper reports the first record of Klein’s sole Synapturichthys kleinii (Risso, 1827) from the Syrian coast. This record confirms the occurrence of the species in the Levant Basin and its eastern extension range in the Mediterranean Sea. However, this single capture of S. kleinii cannot support that a sustainable population is at present substantially established in the same area.
Bycatches of the greenland shark Somniosus microcephalus (Squaliformes, Chondrichthyes) in the barents sea and the adjacent waters under bottom trawling data

Morphological and molecular genetic study of the Persian sturgeon Acipenser persicus Borodin (Acipenseridae) taxonomic status
Journal of Ichthyology - Tập 48 - Trang 891-903 - 2008
G. I. Ruban, M. V. Kholodova, V. A. Kalmykov, P. A. Sorokin
Morphological and molecular genetic analyses of the Russian sturgeon sensu Berg (1934) were accomplished using the sample of individuals collected in the southern part of the Caspian Sea. The distribution of specimens in the space of principal components calculated using 28 morphometric characters demonstrates the absence of separate clusters. Frequency distributions of six studied meristic charac...... hiện toàn bộ
Formation and reduction of provisional ventral foregut diverticulum in the embryos of Anguilliformes as the recapitulation of lungs
Journal of Ichthyology - Tập 57 - Trang 655-667 - 2017
A. M. Shadrin, V. V. Makhotin, K. A. Zhukova
We described the development and subsequent reduction of ventral foregut diverticulum in the early ontogenesis of Anguilliformes in plankton samples collected in the coastal waters of central Vietnam. The diverticulum is a provisional structure derived from the ventral-lateral area of the caudal esophagus. It develops as a protrusion from the esophagus wall and consists of one cell layer. An incre...... hiện toàn bộ
Influence of cadmium ions on some morphofunctional and immune-physiological parameters of perch (Perca fluviatilis, Perciformes, Percidae) underyearlings
Journal of Ichthyology - Tập 49 - Trang 111-118 - 2009
E. A. Zabotkina, T. B. Lapirova, E. A. Nazarova
The changes in some morphofunctional and immune-physiological parameters in perch (Perca fluviatilis) underyearlings exposed to sublethal cadmium chloride concentration have been analyzed. The fluctuations of kidney index values and stimulating effect of toxicant upon humoral factors of nonspecific immunity have been revealed. The leucocytes ratio has been changed most sharply in the peripheral bl...... hiện toàn bộ
