“…Barbour et al (2011) calculated a value of L ∞ = 42 cm for the lionfi sh and Potts et al (2011) of L ∞ = 45 cm; both of them off the North Carolina coast (USA). This parameter was relatively similar to that of the PNAA (L ∞ = 42.5 cm) but higher than that calculated (L ∞ = 34.9 cm) in the Cayman Islands (Edwards et al 2014). Lionfi sh from the PNAA appeared to reach their maximum length faster than fi sh from the Cayman Islands and North Carolina, with K values for fi sh from the PNAA equal to 0.88 and K values for lionfi sh from North Carolina equal 0.32 (Potts et al 2011) and 0.47 (Barbour et al 2011) and Cayman Islands equal to 0.42 (Edwards et al 2014).…”

In general, in comparison to growth rate values for other tropical fi sh (K = 0.1 to 0.3), the lionfi sh appears to reach their asymptotic maximum length faster (Edwards et al 2014).…”

“…(Barbour et al 2011). In the Cayman Islands it amounted to 3.24 (Edwards et al 2014) and in the Bahamas it was 3.29 . In general, parameter b is subject to changes because of sample size, environmental factors, and seasonality (Froese 2006).…”

“…Growth parameters calculated before of specimens from North Carolina (Barbour et al 2011, Potts et al 2011 and Cayman Islands (Edwards et al 2014) were based on readings of sagittal otoliths. The maximum size (39 cm TL) of P. volitans detected in this work is the largest ever recorded in the PNAA, and similar to that detected in a specimen from Cayo Arenas-a site located approximately 50 km to the east from the PNAA (Aguilar-Perera et al 2013).…”

Estimates of lionfi sh's growth parameters in the PNAA may have been affected since there is a lack of older and larger lionfi sh (since the recent establishment of lionfi sh in the area) which may produce a truncated growth curve.…”

Rodríguez-Cortés K.D., Aguilar-Perera A., Bonilla-Gómez J.L. 2015. Growth and mortality of red lionfi sh, Pterois volitans (Actinopterygii: Scorpaeniformes: Scorpaenidae), in the Parque Nacional Arrecife Alacranes, southern Gulf of Mexico, as determined by size-frequency analysis. Acta Ichthyol. Piscat. 45 (2): 175-179.Background. Biological invasions represent a threat to the ecological stability of the ecosystem. Two lionfi sh species, the red lionfi sh and the devil fi refi sh-both tropical marine predators native to the Indo-Pacifi c-were introduced to the Atlantic Ocean. However, only one-the red lionfi sh, Pterois volitans (Linnaeus, 1758)-has reached the level of an invasive species so far. It is crucial to learn its biology and ecology to understand trends of its invasion and impacts on native fauna, and to determine ecological changes as the invasion progresses. This study reports the growth and mortality of P. volitans in coral reefs of the Parque Nacional Arrecife Alacranes, off the northern Yucatan Peninsula, Mexico, in Southern Gulf of Mexico. . Fish total lengths were used to calculate the parameters of the von Bertalanffy growth function (VBGF) of lionfi sh based on the size-frequency analysis routine ELEFAN in the FiSAT II software. Results. A total of 776 lionfi sh (9.0 to 38.9 cm in total length, 7 to 874 g in total wet weight) were collected. The VBGF parameters estimated were L ∞ = 42 cm, K = 0.88 -1 , t 0 = -0.107 years. The total mortality instantaneous rate (Z) calculated by the total length converted catch curve was 2.06 year -1 . Conclusion.This study provides fi rst calculation of growth parameters and mortality of P. volitans in Southern Gulf of Mexico as determined by size-frequency analysis. Results contribute to the knowledge on the biology of P. volitans and to a better understanding of aspects of its biological invasion in the region.
