“…The high AIC values obtained for the linear function and t significantly overestimated L∞ values (Table 2), which represent the asymptotic length the fish, are likely attributed to the absence of small fish in the samples and a poo pronounced deceleration of growth in large mature individuals (Figure 7). Similar ov estimations of L∞ values have been observed in studies of the age of other mori [28,30,31]. The specific growth rates of the studied species between 30 and 45 years of a remain relatively constant (Figure 8).…”

“…The fishing was done using Mustad (Gjøvik, Lepidion schmidti has been poorly studied, and there are currently no publications documenting age and growth of this species. Although there are over 100 species in this family, data on age and growth have only been published for a few, including the common mora Mora moro [22,23], longfin codling Laemonema longipes [24], red cod Pseudophycis bacchus [25][26][27], blue antimora Antimora rostrata [28][29][30][31][32][33][34][35], and Pacific flatnose A. microlepis [36][37][38]. Among the nine valid species in the genus Lepidion, information on growth and age is available for the North Atlantic codling L. eques only [33].…”

“…This method has been successfully used to determine the age of other members of the Moridae family, such as Antimora spp. [30][31][32]34,35,37,38,42]. The otoliths were sectioned to the center, then heated in the flame of an alcohol burner, and polished on abrasive disks with aluminum-oxide or silicon-carbide coating with a grain size of 0.1-0.9 µm (Buehler, Lake Bluff, IL, USA).…”

This study presents the first data of growth and age of Schmidt’s cod Lepidion schmidti, a rare and poorly studied member of the Moridae family (Gadiformes, Teleostei). The research was focused on the Emperor Seamounts area with the aim of investigating the age, growth rates, and longevity of this species. The analysis involved examining annual growth increments on sagittal otoliths. Data were taken from longline catches in 2014 and 2016, resulting in the collection of 140 individuals and the use of 70 otoliths for age determination. The results revealed that Schmidt’s cod can live for up to 49 years, with a mean age of 31.5 years in the catches. The relationship between body weight and total length was described by a power function, indicating positive allometric growth. The most suitable growth model for this species was determined to be the Von Bertalanffy growth equation. These results provide valuable insights to add to the limited knowledge of growth and age in the Moridae family and emphasize the long lifespan and slow growth of Schmidt’s cod.

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.
