“…The stout beardfish P. nobilis is a bathydemersal species occurring in tropical and subtropical seas (45º N–16º S) of the western Indian Ocean (Seychelles, Madagascar, Mauritius, Reunion, Mozambique, and the Durban region), western Atlantic (Bahamas, Cuba, Leeward Islands, Saba Bank, West Indies, US Virgin Islands, and on the northern coast of South America) (Guthertz et al., 1987), and eastern Atlantic (the Azores, Madeira, the Canaries, the Great Meteor Seamount, the Cape Verde Islands, and St. Helena) (Hureau, 1990; Cervigón et al., 1992; Froese and Pauly, 2009). In the East Atlantic it has been only found to be associated with oceanic islands and seamounts (Vinnichenko, 1997, 1998; Ramos et al., 2001), and one specimen has been recently reported from an Atlantic locality near the Strait of Gibraltar (Farias et al., 2007).…”

The present study provides fisheries biology knowledge which will allow the implementation of regulatory measures contributing to the sustainability of the fisheries and the conservation of the stout beardfish Polymixia nobilis Lowe, 1838 off the Canary Islands, north eastern Atlantic Ocean. Males ranged between 16.5 and 38.4 cm fork length (FL) and females from 14.2 to 46.5 cm FL. Sex ratio by size classes provided significant differences in classes higher than 36 cm, being clearly unbalanced in favour of females. Individuals in maturing and mature stages were present during all months sampled, although a spawning peak is evident between April and June. Size at first maturity was estimated as 26 cm FL for females and 30 cm FL for males. Age was determined from annuli in whole otoliths. Age range was found to be 0-14 years for fish measuring 14.2 to 46.5 cm FL. It is a slow-growing and long-lived species. Significant differences in the growth parameters between sexes were detected. The von Bertalanffy growth parameters estimated for females (n = 213) were L ¥ = 45.92 cm LF, k = 0.16 years )1 and t 0 = )2.84 years; and for males (n = 186) L ¥ = 36.44 cm LF, k = 0.26 years )1 and t 0 = )2.16 years. Stomach analysis indicated some variations in the feeding habits with growth: individuals of small and medium sizes preyed on crustaceans and fishes, while large specimens preyed mainly on fishes.
