ROSA, Yesica DE LA; ACERO P, Arturo  e  GARCIA-URUENA, Rocío. Notes on the reproduction, morphology and ecology of Pareques acuminatus (Teleostei: Sciaenidae), in the region of Santa Marta, Colombian Caribbean. Acta biol.Colomb. [online]. 2020, vol.25, n.3, pp.374-385.  Epub 24-Dez-2020. ISSN 0120-548X.  https://doi.org/10.15446/abc.v25n3.78602.

The highhat, Pareques acuminatus, is a carnivorous, small sized species, with distribution in the western Atlantic from North Carolina and Bermuda to Brazil. Studies on the biology and ecology of P. acuminatus are scarce and in Colombia no work has been done concerning this specie. For this reason, this study focused on knowing the biology of this sciaenid and determining ecological aspects in order to expand its knowledge in the Colombian Caribbean. Captures of the highhat were made by free diving between 2017 and 2018 and visual fish censuses were taken on the habitat where it was observed between 2017 and 2018. The morphometrics and meristics were taken, the reproductive phases identified, and the partial fecundity estimated by the gravimetric method. A total of 85 individuals were collected with a TL between 33 and 185 mm (123.7 ± 36.3 mm) with individuals between 121-142 mm (42 %) as the more frequent, followed by 143-164 mm (20 %). There were 39 females, 34 males and 12 indeterminate juvenile specimens. Females reach mature state with 118 mm TL, being an asynchronous species, with two reproductive phases (phase in development and phase capable of spawning). The estimated partial fecundity was 8744 ± 3900 oocytes, and the relative fecundity in relation to size was 64.15 ± 25.51 oocitos/mm with a diameter of 0.53 ± 0.04 mm. The highhat is a typical specie of shallow reef habitats, and was found mainly accompanied by Myripristis jacobus, Canthigaster rostrata, Haemulon steindachneri, H. flavolineatum, Stegastes partitus and Chromis multilineata between 2017 and 2018.
