“…En el PNG no existe un programa de manejo dirigido para el pez león, solo se han realizado capturas con fines científicos (Cobián et al, 2016). En cambio, en el PNAX se ejecuta un programa eficiente de manejo desde el 2009 a través, de torneos de pesca y programas gubernamentales de empleo temporal (Sabido-Itzá, Medina, Navarrete, Gómez-Poot, & García-Rivas, 2016). En el PNAX el pez león ocupó el lugar 35 y fue menos abundante, lo que pudiera indicar el efecto positivo de los programas sistemáticos de remoción (Barbour, Allen, Frazer, & Sherman, 2011;De León et al, 2013).…”

“…Thus, it is probable that PNAX is a very important place for lionfi sh recruitment (Vásquez-Yeomans et al 2011). In the PNAX, there was a change in modal groups into larger size classes from 80-160 mm TL in [2009][2010][2011] (Sabido-Itzá et al 2016) to 240-280 mm in 2012-2013. This may imply that lionfi sh population is experiencing a growth trend (Côté and Maljković 2010, Pusack et al 2016).…”

“…In fact, so far the RBBC and the PNAX are under culling program for lionfi sh with the collaboration of voluntary fi shermen. Such programs are expected to foster conservation efforts of these natural protected areas (Sabido-Itzá et al 2016). In addition to continuing the culling program, it is recommended to conduct surveys to estimate lionfi sh density.…”

“…Lionfi sh represents a threat to the biodiversity and stability of the marine ecosystems due to its high voracity (Morris and Akins 2009) causing reduction in the abundance of native fi sh and invertebrates (Albins and Hixon 2008, Côté et al 2013, Ballew et al 2016. In Mexico, lionfi sh was detected in the late 2009, both in the Mexican Caribbean and southern Gulf of Mexico (Aguilar-Perera and Tuz-Sulub 2010, Sabido-Itzá et al 2012), where now it is considered as established (López-Gómez et al 2014, Sabido-Itzá et al 2016. Thus, it is imperative to know further its biology to understand the ecological effects due to its invasion in the marine ecosystem of the region.…”

Sabido-Itzá M.M., Aguilar-Perera A., Medina-Quej A. 2016. Length-weight and length-length relations, and relative condition factor of red lionfi sh, Pterois volitans (Actinopterygii: Scorpaeniformes: Scorpaenidae), from two natural protected areas in the Mexican Caribbean. Acta Ichthyol. Piscat. 46 (4): 279-285.Background. Biological invasions are often listed among the main threats to the ecosystem and are considered drivers of biodiversity loss. The Indo-Pacifi c lionfi sh, Pterois volitans (Linnaeus, 1758) (hereafter lionfi sh), invaded the Atlantic Ocean where it threatens the stability of the marine ecosystem. It would be crucial to know its biological characteristics to understand how environmental parameters could affect its growth. It is also important to continue the earlier efforts of management and control. In this study, we described the L-W and L-L relations and the relative condition factor of lionfi sh in two natural protected areas in the southern coast of Quintana Roo, Mexico. . The relative condition factor was calculated through the relative weight. Results. A total of 817 lionfi sh were caught in the frames of this study. In this number, there were 449 individuals from the RBBC (282.1 ± 62.1 mm TL) and 368 from the PNAX (249.2 ± 77.6 mm TL). The L-W relation for lionfi sh from the RBBC was W = 0.0041 TL 3.258 and that for the PNAX was W = 0.0049 TL 3.191 . There was a signifi cant difference between these relations (ANCOVA, F = 3.91; P = 0.0481). The growth type was positive allometric. The L-L relation was signifi cant. The relative condition factor differed between areas only in 2013, but a high value was determined in 2012. Conclusions. The L-W relations were different between locations (RBBC and PNAX) but no between years. The relative condition factor showed high values (>100) for both locations which may imply that lionfi sh is in good shape, in the studied location, due to environmental factors providing good food supply and because of the lack of predators. These results may be useful as a baseline to document the population dynamics of lionfi sh in the region.

Distribution and abundance of the lionfish Pterois volitans (Scorpaeniformes: Scorpaenidae) and associated native species in Parque Marino Cayos de San Felipe, Cuba. The first lionfish sighting at the National Park "Cayos de San Felipe" was in 2009 and could be a threat to its marine ecosystem diversity and their capacity to generate services. To analyze the incidence of the lionfish invasion in the area, an annual sampling was conducted between 2013 and 2015. Lionfish abundance and size was investigated on mangroves through visual census on ten transects of 30x2 m/station, and on coral reefs (15 and 25 m deep) with stereo video on six transects of 50x2 m/station. Additionally, incidence of potential native competitors and predators on coral reefs were also estimated. Over the three years, the average density of lionfish varied between 0.0-1.3 indiv./100 m 2 per sample stations and it was not significantly different among habitats (mangroves with 0.6 indiv./100 m 2 , reefs at 15 m -0.4 indiv./100 m 2 and reef at 25 m with 0.3 indiv./100 m 2 ). Lionfish's density was equal to or lower than competitors' density, and was equal to or higher than predator's density in both depths. While lionfish density on mangroves and on reefs at 25 m remained temporally stable, it decreased on reefs at 15 m. Temporary increase in the competitor's density was observed and the predator´s density did not change during the monitored time. Lionfish size varied between 5 and 39 cm; the average fish size from mangroves (12.6 cm) was consistently lower than from reefs (25.2 cm) and showed no variations among years. Lionfish size in reefs was higher than competitor's size and lower than that of predator. Results showed that in the park: 1) mangroves represent lionfish nursery areas; 2) incidence of reef lionfish was not as high as in other areas of Cuba and the Caribbean; and 3) lionfish abundance in reefs tended to decrease over the years, without the intervention of extractive activities or high abundance of large size native groupers. In this sense, recommendations are made to continue monitoring and to investigate lionfish effects and factors that are regulating its incidence in the park. Rev. Biol. Trop. 65 (1): 117-125.
