Isolated Fluvial Population of Dolly Varden Salvelinus malma on Bering Island (Commander Islands)
Journal of Ichthyology - Tập 61 - Trang 418-432 - 2021
A. M. Malyutina, K. V. Kuzishchin, A. V. Semenova, M. A. Gruzdeva
For the first time on Bering Island (Commander Islands), an isolated population of northern Dolly Varden Salvelinus malma has been found. It inhabits only the Vodopadnaya River, which is separated from the sea by an insuperable for migratory fish waterfall, 6 m high, and does not house any other fish species. The Dolly Varden charr of isolated population are stunted with lifespan up to 12 years; t...... hiện toàn bộ

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

Age-Related Melanism in Macroparalepis brevis (Paralepididae)
Journal of Ichthyology - Tập 63 - Trang 161-165 - 2023
A. M. Prokofiev
Age-related melanism for a dwarf species of the genus Macroparalepis, M. brevis, was described for the first time; thus, this phenomenon turns out to be a common generic character. Presumably, the trigger for coloration change is the transition to a mesobenthic lifestyle. The phylogenetic significance of age-related melanism in barracudinas (Paralepididae) is discussed, which may support a kinship...... hiện toàn bộ
Dynamics and the state of fishery resources in the Rybinsk Reservoir from 1950–2010
Journal of Ichthyology - Tập 53 - Trang 486-498 - 2013
Yu. V. Gerasimov, A. S. Strelnikov, S. Yu. Brazhnik
Data on dynamics of the main commercial fish populations in the Rybinsk Reservoir over the period of 1950–2010 have been generalized. Fishing intensity is the main factor that determines the state of fish resources. It affects not only the abundance of commercial fish but also determines changes in population characteristics, i.e., changes in age and size structure and increase in the portion of y...... 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
