Fishes of the family Melamphaidae over the seamounts of the central Atlantic ocean
摘要
The data on catches of fishes of the family Melamphaidae over seamounts of the central part of the Atlantic Ocean, mainly over the Mid-Atlantic Ridge, are presented. The material was collected during expeditions on the research vessels “Akademik Sergei Vavilov” (voyage 43, 2016), “Prof. Logachev” (voyage 39, 2018), and “Akademik Mstislav Keldysh” (voyage 87, 2021–2022). Morphometry of fish of 12 species belonging to the genera Melamphaes, Poromitra, Scopeloberyx, and Scopelogadus is given, coloration features of fixed individuals are indicated, and distribution in the World Ocean is described. For several species, catches far from previously known habitats are recorded.

A reliable finding of Pleurogrammus azonus (Hexagrammidae) off the coast of Kamchatka with notes on the permanence of its habitation in the northern part of distribution range
摘要
Pleurogrammus azonus was reliably found off the coast of Kamchatka. A morphological description of a specimen caught in Kronotsky Bay is given in comparison with representatives of the species from other parts of its distribution range. P. azonus can be encountered in the waters of the Sea of Okhotsk near Kamchatka in both spring-summer and winter periods, which implies the presence of a permanent local aggregation, strongly dependent on recruitment from more southern areas it inhabits. In catches, it is represented by fish of 24−35 cm fork length, which may exceed the closely related P. monopterygius by population size. P. azonus entered the waters off the Pacific coast of Kamchatka presumably due to migrations of individual adults from nearby areas on the Sea of Okhotsk side of the peninsula, as well as Shumshu and Paramushir islands.

Comparison of methods for studying the age of the giant grenadier Coryphaenoides pectoralis (macrouridae) by scales and otoliths
摘要
On the basis of the prepared preparations for age reading, an analysis was made and it was shown that the age of scales is significantly underestimated, compared with the technique when otolith sections are used. The results cast doubt on existing ideas about the growth of the macrurus. The question of interpreting the age of the small-eyed macrurus for all age groups remains open.

Development of Pholis crassispina (pholidae) larvae from the waters mottled gunnel of peter the great gulf, sea of japan
摘要
The article describes the larvae and provides the main meristic features of juvenile and mature Pholis crassispina specimens from the waters of Peter the Great Gulf, Sea of Japan. An original scheme for designating melanophores is proposed. The dynamics of melanophore coloration development in larvae is described. The cleithral pigment in this species is present from the preflexion stage. At the same stage, after reaching an absolute body length of 14.3 mm, a superficial melanophore row appears on the sides of the abdomen; melanophores can have a ray structure or appear as dots. After a body length reaches approximately 18.4 mm, each postanal ventral melanophore corresponds to one segmented ray of the anal fin. From this larval length, the number of segmented rays in the anal fin can be determined by counting the number of melanophores at their bases. A set of features is proposed that allows reliable identification of P. crassispina larvae at each stage of development.

Changes in age, size and growth rate of the Anadyr chum salmon Oncorhynchus keta (salmonidae) under conditions of global warming
摘要
The results of the study of annual variability in age composition, body size and growth rate of the Anadyr chum salmon Oncorhynchus keta in 2011−2023 revealed that the length and body weight of individuals of all age groups in 2016−2023 significantly decreased compared to the previous period, especially in fish aged 0.4. The proportion of fish of the younger age groups increased. Based on the calculated data, in 2012−2022, the growth rate of chum salmon decreased in the first to second years of life, and multidirectional trends were observed in the third to fourth years, with the lowest increase in the body length in 2016 and 2020. The decrease in the production characteristics of Anadyr chum salmon in the modern period occurred simultaneously with a decrease in the abundance of this salmon species throughout its entire marine range in the North Pacific and depended little on the abundance of other salmon species. The data obtained cast doubt on the leading role of the so-called density factor in determining the production characteristics of fish, which is expressed in food shortages due to an increase in the abundance of Pacific salmon. The abnormally high surface temperatures in the northeast Pacific Ocean over the past seven to eight years have had a marked negative impact on the growth of Anadyr chum salmon.

Dynamics of abundance and biological parameters of the European grayling Thymallus thymallus (salmonidae: thymallinae) of the Timan watercourse according to long-term observations
摘要
An analysis of long-term data on the relative abundance, sexual maturation, linear growth and age structure of the European grayling Thymallus thymallus (Linnaeus, 1758) living in one of the watercourses of the middle Timan in the area of bauxite mining and transportation, is presented. It is shown that in the absence of significant disturbances to habitats, the dynamics of abundance and structural and functional parameters of the grayling aggregations are determined to a greater extent by the intensity of non-commercial fishing than by climatic conditions. If the exploitation load is reduced and the quality of the aquatic environment is maintained, the grayling population in the Vym River can be expected to restore to the level characteristic of undisturbed aggregations of this fish species.

Infestation of young northern pike Esox Lucius (esocidae) with macroparasites in different reaches of the river continuum
摘要
The composition of infracommunities and quantitative characteristics of infestation of underyearlings of northern pike Esox lucius with macroparasites have been studied in the small Ild River (a second-order tributary of the Rybinsk Reservoir) from different reaches of the river continuum (from the upper reaches to the mouth). The number of parasite species, mean abundance, and prevalence were significantly higher in the lower reaches than in the upper reaches of the river. Pike samples from different reaches significantly differed in the infection variability between the individuals. The highest coefficient of variation in the number of parasites in one fish individual was observed in the sample from the upper reaches (162%), while it was significantly lower in individuals from the middle and lower reaches (89 and 57%, respectively). Among various parasites from the lower part of the river, we have recorded manipulators of host behavior, which increase the fish availability for predators. These include several trematode species (Trematoda) of the family Diplostomidae. Underyearlings from the sample from the upper reaches were most variable in size, dominated by small individuals. The specimens from the lower reaches were characterized by a minimum variability in body length. The largest (on average) individuals were recorded in the sample from the middle reaches. Parasites are presumably a significant factor influencing the pike population structure and migratory activity, which is usually considered a sedentary species.

Taste responses of carp fishes (Cyprinidae) to carboxylic acids. 1. Taste preferences
摘要
The palatability of carboxylic and some other organic acids (10− 1 M) for dace Leuciscus leuciscus, roach Rutilus rutilus, and common carp Cyprinus carpio was assessed. The conclusion about species specificity of taste preferences in fishes was confirmed. Four out of 17 carboxylic acids stimulate consumption of pellets in dace, of which formic acid has the strongest effect. A significant decrease in consumption is caused by ten acids. For roach, no palatable carboxylic acids were found; most of them (13 out of 15) have a repulsive taste. For common carp, four acids have attractive taste, one (malonic acid) has repulsive taste, and the remaining 11 acids have no effect on pellet consumption. The stimulating effect of the acids persists up to concentrations of 10−4 and 10−3 M. Among the carboxylic acids, there is not one with the same taste properties for the studied fish. No significant similarity was found between dace, roach, common carp, and other fish species in terms of palatability of carboxylic acids. A direct dependence of pellet consumption on pH of carboxylic acid solutions was observed in roach and dace, while it was absent in common carp. The dependence of the palatability of carboxylic acids on the size of their molecule is weakly expressed. Structural transformations of the acid molecule do not always lead to shifts in taste properties, and in different species, they may not coincide or be opposite. Ascorbic acid (vitamin C) has a repulsive taste for roach, indifferent for dace, and attractive for common carp, which confirms the lack of relationship between physiological needs in essential micronutrients and their palatability, shown earlier on the example of amino acids.

Lampreys (Petromyzonti) and ray-finned fishes (Actinopterygii) in the editions of the red data book of Russia of 1983–2021
摘要
The sections on lampreys and fishes in three editions of the Red Data Book of Russia (1983, 2001, and 2021) have been analyzed. Changes in species composition and the reasons that caused them are considered. The history of the formation of categories of rarity and endangerment statuses in the Russian Red Data Books and their close connection with the Red Data Book and the International Union for Conservation of Nature Red List is shown. The need for categories of conservation status (I, II, and III priorities of conservation measures) is considered. Changes in approaches to listing species in different editions are analyzed. A number of problematic issues in maintaining the Red Data Book of Russia are noted. Proposals are put forward for the formation of a list of lamprey and fish taxa to be listed in the next edition of the Red Data Book of Russian Federation and the selection of status categories for them.

On the finding of a new prickleback species for the fauna of Russia, the mosshead warbonnet Chirolophis nugator (Stichaeidae), in the intertidal zone of Bering island (Commander islands)
摘要
The article presents data on the first discovery of a new species of pricklebacks (Stichaeidae) for the fauna of Russia in the intertidal zone of Bering Island (Commander Islands), the mosshead warbonnet Chirolophis nugator (Jordan et Williams, 1895). Its specimen, with a total length of 47 mm, was most likely brought to the waters off Bering Island at the pelagic larval stage from the nearby Aleutian Islands by the westward-flowing Aleutian Current.
