“…The similarity of blue antimora growth patterns in the Ross, Lazarev and Weddell seas and the waters of Kerguelen and Crozet Islands might indicate that this species forms a single population in the Southern Ocean that might be confirmed by recent molecular genetic study (Orlov, Bannikov, & Orlova, 2020). This study also showed a difference of haplotype composition between blue antimora samples from the Southern Ocean and the North Atlantic.…”

Age and growth of Antimora rostrata (Moridae, Gadiformes, Teleostei) from the Kerguelen and Crozet Islands in the southern Indian Ocean

AbstractAge and growth of blue antimora Antimora rostrata were examined for the first time in the waters of Kerguelen and Crozet Islands (southern Indian Ocean, sub-Antarctic). The longline catches were represented by fish ranging from 39 to 72 cm in total length with weights between 400 and 3310 g, aged 16– 41 years. A minimum age of 16 years was observed in a fish 39 cm long, while a maximum age of 41 years was recorded for an individual of 70 cm in length and 3310 g in weight. The age classes with the greatest numbers were represented by fish aged 34 years (9%), 28 years (9%) and 29 years (8%), which together accounted for 26% of the total catch. The blue antimora in the southern Indian Ocean shows similar growth rates to those of individual fish from the Ross, Lazarev and Weddell Seas and southeastern Greenland, which may indicate the population unity of the species within the Antarctic and sub-Antarctic waters or similar habitat conditions in these areas.

“…At the same time, considerably different age and growth characteristics of blue antimora in New Zealand waters and off the Macquarie Island may testify to existence of different populations in these areas. However, further genetic research is needed toward evaluation of population structure of blue antimora in southwestern Pacific and adjacent Southern Ocean as well as in other parts its wide range [5,42]. The growth curve for specimens of blue antimora from Macquarie Island (our data) being compared (Figure 12, Table 1) to those for the Ross Sea [9], the waters off Greenland [18], the Lazarev and Weddell Seas [16], and Kerguelen and Crozet Islands [17] revealed undeniable resemblance.…”

“…Blue antimoras from New Zealand waters [9], and our data, along with those from Flemish Cap area [19] show the slowest growth rates, while in the North Atlantic [8], this species demonstrates the fastest growth as compared to the other parts of the species' range. One of the possible reasons for the slow growth of blue antimora in the northwestern Atlantic and New Zealand waters might be its high abundance in these areas [5,7] since it is known that density factor in the population may considerably impact the growth rate of its individuals [41]. At the same time, considerably different age and growth characteristics of blue antimora in New Zealand waters and off the Macquarie Island may testify to existence of different populations in these areas.…”

“…The range of Pacific flatnose is limited by the North Pacific. The blue antimora has a circumglobal distribution, except the North Pacific Ocean (north to 10ºN), more common in temperate and cold waters, but absent from the Artic Ocean, some semienclosed seas as well as in most tropical and subtropical regions [1,2,4,5]. This benthopelagic species usually inhabits depths of 800-1800 m and can form dense concentrations in some areas.…”

Age and growth of blue antimora Antimora rostrata were examined in the waters off New Zealand and Macquarie Island (southwestern Pacific). Samples off Macquarie Island were collected from bycatch in the Patagonian toothfish longline fishery. Individuals between 20 and 44 years in age measured between 37.6–71.1 cm in total length. Bottom trawl catches from New Zealand waters consisted of smaller and younger fish (11 to 38 years), measuring 22.5–52.5 cm long. The age classes with the greatest numbers in the former area were represented by fish aged 33–34 years (25.7%). In the latter area, the most numerous age classes were 21–23 years (12.1%), 28–29 years (17.6%), and 32 years (6.6%). The blue antimora from off the Macquarie Island show similar growth rates to those of individual fish from the Ross, Lazarev and Weddell Seas, waters off the Kerguelen and Crozet Islands, and southeastern Greenland. Individuals from New Zealand waters demonstrate the slowest growth rates compared to other parts of the species’ range but are quite similar to individuals from the Flemish Cap area. Further research to identify the stock structure of this broadly distributed species is warranted to provide context to differences in growth rates observed between populations.

The first records of walleye pollock Gadus chalcogrammus Pallas, 1814 in the seas of the Siberian Arctic (the Laptev Sea, the Kara Sea, the southeastern Barents Sea), are documented. Information about the external morphology (morphometric and meristic characters), photos of sagittal otoliths and fish, and data on the sequences of the CO1 mtDNA gene are presented. The results of a comparative analysis indicate that walleye pollock caught in the Siberian Arctic do not differ in principle from North Pacific and North Atlantic individuals. Previous conclusions about the conspecificity of the walleye and Norwegian pollock Theragra finnmarchica are confirmed. New captures of walleye pollock in the Siberian Arctic allow us to formulate a hypothesis about its continuous species’ range from the coasts of Norway in the North Atlantic to the coasts of Korea, Japan, and California in the North Pacific. The few records of walleye pollock in the North Atlantic originate from the North Pacific due to the transport of early pelagic juveniles to the Arctic by currents through the Bering Strait and further active westward migrations of individuals which have switched to the bentho-pelagic mode of life.
