The bluefish, Pomatomus
saltatrix (Linnaeus, 1766), the only representative of the Pomatomidae
family, is a key fishing resource that represents a substantial part of the
landings at RESEX-Mar of Arraial do Cabo-RJ. The species
is broadly distributed throughout the continental shelf in tropical and warm
temperate waters of the Atlantic, Pacific and Indian Oceans. It forms pelagic,
large and fast moving shoals in relatively deep offshore waters, and draws
close to the coast when temperatures reach from 12¡æ to 15¡æ. Its displacement is conditioned to the
movement of shoals of small
fish such as herings; shrimp and squid, all of which are preyed upon. This work
had the main purpose of evaluating the growth of bluefish through the
distribution of length frequency (One-Way-ANOVA) and the Relationship
between Total Length¡ªTL (mm) and Total Weight¡ªTW (g)-LWR; from daily data
collections from March/2017 to March/2018. The analyzed specimens were obtained
at fish markets of Arraial do Cabo-RJ and fish landings at the Fishermen¡¯s
Harbor of Praia dos Anjos. They were randomly sampled from fragmented cohorts
of the local stock. A total of N = 2057
specimens were primary analyzed. TL values varied from 201 mm (minimum)
in February/2018 to 915 mm (maximum) in September
2017. The average TL was of 541 mm
and the average TW of 1428.5 g. The value of angular coefficient ¡°b¡± in
the potential flow was 2.6, and the value of ¡°a¡± was 9E-05, expressed by the equation W = aLb for overall, where W =
TW and L = TL. Values of W = 3E-05L2.7 were found for females and
W = 2E- 05L2.8 for males. Knowledge over their general biology is
extremely important when it comes to knowing the ecology of this species for
subsidize a future and adequate fishery management.
