Resumen

SOUSA, R. et al. Weight-length relationships of six shrimp species caught off the Madeira Archipelago, Northeastern Atlantic. Braz. J. Biol. [online]. 2019, vol.79, n.1, pp.133-138.  Epub 19-Abr-2018. ISSN 1519-6984.  http://dx.doi.org/10.1590/1519-6984.180731.

Length and weight relationships and descriptive statistics are reported for six shrimp species caught off the Madeira archipelago between 1983 and 2014 using bottom and floating traps from depths ranging from 50 to 1,300 m. The parameter b ranged between 2.36 for Plesionika ensis and 2.97 for Plesionika williamsi. All species showed a pattern of negative allometric growth. To the authors’ knowledge all weight-length relationships presented herein are recorded for the first time from the Madeira area, and in the cases of Ligur ensiferus and Plesionika ensis are the first references worldwide.

Palabras clave : carapace length; negative allometric growth; weight-length relationships; shrimps; Madeira archipelago.
