“…In conclusion, the first stock assessment study of lionfish by the UVC method in Turkish marine waters revealed that there is a high density and biomass of lionfish in the region, which is negatively affecting regional native biodiversity as confirmed by other studies (Hixon et al, 2016;Sabido-Itzá and García-Rivas, 2019). The density and biomass of lionfish found in this study for the Mediterranean were much higher than that for the Atlantic and Pacific Oceans, which might be due to the high availability of small fishes and decrease of top predators as a result of overexploitation in the Mediterranean.…”

Underwater visual census (UVC) is a commonly used approach for assessing fish density and biomass. Iskenderun Bay, comprising the Samandağ coast in Turkey, is the most important introduction pathway of alien species in the northeastern Mediterranean. In this study, the density, abundance, distribution and interaction of invasive lionfish or devil firefish Pterois miles were assessed using the UVC method on the Samandağ coast. The total transect area monitored on the Samandağ coast was 4.500 m2. Species richness, Shannon’s diversity index and rate of biomass were 25, 1.81 and 73.5 m2, respectively. Reduced diversity was observed with increasing depths. The sandy seafloor was a limiting factor for lionfish distribution. There was a significant positive correlation between lionfish total density and both the Shannon diversity index (r = 0.99, P<0.001) and Shannon evenness index (r = 0.99, P<0.05). A high number of significant positive correlations (P<0.05) were detected between the occurrence of lionfish and the occurrence of both the native species and other alien species. The first stock assessment study of lionfish by the UVC method in Turkish marine waters revealed that native species are under very high pressure from lionfish species, especially Chromis, Sparids and Wrasses, indicating negative effects of lionfish on regional native biodiversity.

“…No obstante, se ha documentado que la aplicación de este método puede subestimar la abundancia real dado que no considera la naturaleza críptica de la especie, además de las condiciones físicas del arrecife (Kulbicki et al 2012. Por tal motivo, actualmente se utilizan censos dirigidos hacia la búsqueda específica del pez león con la finalidad de obtener resultados más precisos (Anderson et al 2017, Hackerott et al 2017, Sabido-Itzá & García-Rivas 2019.…”

The visual census of band transect (CVB) is one of the most used monitoring protocol on reefs, however this study confirms that its application fail in the detection and estimation of abundance of invasive lionfish. CVB vs Lionfish Search Census (CBP) was compared on Mexican Caribbean reefs. Differences in abundance of lionfish were found between CVB and CBP. Bias among both methods was significantly correlated to the cryptic behavior of inactivity and depth of the site. Finally, the use of different lionfish sampling methods and the application of CBP for monitoring reefs in the region are discussed.
