First Study of Invasive Lionfish (Pterois sp.) Population Dynamics in Martinique, Lesser Antilles Using Photo-Identification Method

“…According to some preliminary studies, the female may release up to 30,000 eggs every four days (Maréchal and Trégarot 2015). The high growth rate of this species (on average 0.45 mm/day for the male and 0.08 mm/day for the female) reinforces the invasive nature of lionfish (Trégarot et al 2017). This rapid growth is directly correlated with the rate of predation (Trégarot et al 2017).…”

“…Since the beginning of the lionfish invasion, control strategies and studies of this species have been set up. For several studies, the capture-mark-recapture method has been used, with the placement of tags on the individuals (Jud and Layman 2012;Trégarot et al 2017). This technique was very invasive, involving the capture of individuals in nets and their manipulation.…”

“…Divers are also more exposed to the risk of being stung by lionfish fin spines. In addition, an impossibility of identification of the fish was observed because of a possible loss of tags or biofilm installed on the tags making the numbers and/or colors indistinguishable (Trégarot et al 2017).…”

Biodiversity policy and subnational implementation in the remote regions of France

“…With the exception of Lagabrielle’s ( 2007 ) work on the planning of biodiversity conservation in Reunion, research with this focus and geographical scope is scarce if non-existent. Some policy reports have been produced, for instance, in the framework of the BEST Initiative and IFRECOR 4 (Trégarot & Failler, 2021 ; Trégarot et al, 2015 ), while a few articles discuss the policy responses to climate change (Magnan & Duvat, 2018 ; Ribalaygua et al, 2019 ). However, most of this research precedes important policy changes that have occurred in France and Reunion in the last few years.…”
