AbstractThe dynamics of the Atka mackerel stock in the Olyutorsky–Navarin area in 1994–2019 is inferred from bottom-trawl surveys, fishery statistics, open-access NOAA data, and the results of simulation by the method of virtual population analysis. After the period of low stock in the mid-1990s, the abundance of the Atka mackerel group in the area...

AbstractThe distribution of fish and prawn in the bed of the lower Amur River (within 40–960 km from the mouth) is described based on the results of a beam-trawl survey (57 trawl taw at depths of 1.5–23.0 m) conducted in September and October 2003. A total of 2584 ind. of 22 fish species and 1077 ind. of one invertebrate species (the prawn Palaemon...

AbstractThe density and biomass of aggregations of the clam Mya uzenensis have been studied in four areas of the littoral zone in Taui Bay. Aggregations of this bivalve species were mosaically distributed in the form of beds from 0.5 to 5.0 m2 in size. On suitable sediments, Mya aggregations occupied 25–40% of the littoral zone area. The structure ...

AbstractThe current status of the red king crab population off western Kamchatka is considered based on data from bottom trawl surveys and fishery statistics since 2013. Some biological parameters of this crab species are provided; its commercial stock is estimated; some features of red king crab fishery and determination of total allowable catch f...

AbstractThe effect of water temperature on the timing of spawning and spat settlement of the Yesso scallop (Mizuhopecten (=Patinopecten) yessoensis Jay, 1857) in Minonosok Cove (Posyet Bay, Peter the Great Bay) has been studied based on the most complete dataset of observations for 1970–2011. The date of onset of spawning varied from May 1 to June ...

AbstractAn original method is proposed for rapidly differentiating between regional pink salmon runs with different timings of spawning and states of gonads (gonadosomatic indices, GSI). The results of differentiation obtained by the original and traditional methods are compared. The concept of spatial niches for various temporal groups of Sea of O...

AbstractAn aerial survey of Pacific salmon spawning grounds in the main watercourses that empty into the Bering Sea was conducted for the first time since 1992. The total flight time was 35 h; the approximate total length of transects was 3800 km. The number and distribution of Pacific salmon spawners in the Anadyr, Velikaya, Tumanskaya rivers and ...

AbstractThis study provides biological, fishery, and production characteristic of spawning females of a triple hybrid between the Russian sturgeon, Siberian sturgeon, and Amur sturgeon (RS × SS) × AS and other commercial hybrid sturgeon forms grown in the cages of a warm-water fish farm in Primorsky Krai, Russia. The survival rate of larvae and juv...

AbstractThe growth parameters were determined separately for the two sexes of Penaeus kerathurus, as well as for the two (northeastern and southern) substocks of the species in Tunisia. Seasonal sampling from catches of this species in the coastal and the offshore waters was carried out during the period between 2010 and 2012 for the northeastern s...

AbstractA seasonal spring-run (vernal) ecotype of the Steelhead Trout Parasalmo (Oncorhynchus) mykiss (Walbaum, 1792) has been found in western Kamchatka for the first time. Fish of this ecotype perform anadromous migration in May; however, the timing and grounds of spawning of the spring- and fall-run (hiemal) ecotypes in Kamchatka completely over...
