“…In this publication we identify every visible ring as annulus similarly to our previous research in which age estimations remained invalidated. However, our recent study [38] has demonstrated similarity of the number of rings found on otoliths and vertebrae in most cases. Consequently, we suppose that otolith and vertebrae rings are both laid annually.…”

“…Despite the number of studies dealing with age and growth of blue antimora that were recently conducted, its age determinations require further investigation in order to validate the annual deposition of rings and confirm the real age. An attempt was made to estimate the age of blue antimora congener, Pacific flatnose A. microlepis, with the use of vertebrae reading [38]. The results showed a similar number of rings on otoliths and vertebrae taken from the same fish.…”

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.

“…Afterwards, a thin transversal section (about 0.5 mm) was carried out through the core (nucleus). To further support age estimation, the first two vertebrae after the skull were sectioned (KOROSTELEV et al, 2020). Finally, the whole vertebrae, as well as the otolith and vertebrae sections, were viewed under a stereoscopic with 1.0x magnification (Leica Mz12.5) with reflected light and were then photographed (Leica Microsystems, DFC450 C).…”

On July 7th 2018 a specimen of Mediterranean dealfish (Trachipterus trachypterus Gmelin 1789) was caught in the shallow waters of Selinunte (in the South-Western coast of Sicily) by trammel net. It was a female in maturing phase and the gonadosomatic index resulted as 1.1%. The specimen measured 1638 mm in total length and weighed about 2480 g. The estimated age through growth increments in vertebra was of 41 years. The finding of the Mediterranean dealfish in the Strait of Sicily might be linked to its spawning period during which it approaches the shallow waters. The present specimen represents the first record in the Strait of Sicily.

“…A widely employed method for estimating the age of fish using otoliths, which has demonstrated success in demersal (including deep-water) species inhabiting the waters along the west coast of the USA and Canada [40], is the "break and burn" technique. This method has also proven effective in studying the age of some morid species [41][42][43][44][45][46][47][48][49].…”

Physiculus cynodon is a member of the Moridae family and possesses a ventral bioluminescent organ. Although it has been captured by commercial vessels for decades, our understanding of its biology and ecology remains fragmented. This paper provides data on the species’ spatial and vertical distributions; age and growth; size, age, sex compositions; and sex ratio in the waters around the Emperor Seamounts and the northwestern Hawaiian Ridge. This information is based on the analysis of multi-year Russian data obtained from scientific surveys and observations on commercial fishing vessels. The northernmost capture of this species has been recorded at Nintoku Seamount. Additionally, this species was regularly encountered at depths ranging from 53 to 900 m on seamounts such as Lira (Annei), Koko, Milwaukee (Yuryaku and Kammu), Colahan, and C-H of the Emperor Seamounts and Hancock, Zapadnaya, and Academician Berg of the northwestern Hawaiian Ridge. Catch rates of P. cynodon gradually decreased in a southeastern direction. Notably, the relative abundance of this species in bottom trawl catches significantly surpasses that in pelagic catches. The age of the fish in the catch varied from 9 to 37 years, and its growth is described by the VBGF equation with the following coefficients: L∞ = 858.6, k = 0.030, t0 = 3.5. While the growth patterns for males and females were similar, it is worth mentioning that males rarely survive beyond the age of 25 years.
