Abstract
This work shows an update of the sightings and reports of tiger shrimp Penaeus monodon on the Mexican coast of the Gulf of Mexico recorded from 2012 to 2019 and reports the smallest specimen found in the western Atlantic. The results show an increase of almost 300% in sightings and reports since the first report. The zone with most sightings and reports was the coast of Campeche and Yucatán. The wide range of size and distribution of the captured specimens, including the smallest specimen found in the western Atlantic and the presence of females at an advanced stage of gonadal maturity, indicates that P. monodon has established itself in the area. The possible negative effects of such establishment make necessary the proposal of measures based on scientific evidence.

The Asian tiger shrimp, Penaeus monodon Fabricius, 1798, is a penaeid widely distributed throughout most of the Indo-West Pacific region, its fishing grounds are mostly located in tropical countries, in Indonesia, Malaysia and the Philippines (Motoh 1981) and it is an invasive species in the Eastern Mediterranean (Khafage et al 2019) and West Africa (Clotilde-Ba et al 1997)
Summary
The Asian tiger shrimp, Penaeus monodon Fabricius, 1798, is a penaeid widely distributed throughout most of the Indo-West Pacific region, its fishing grounds are mostly located in tropical countries, in Indonesia, Malaysia and the Philippines (Motoh 1981) and it is an invasive species in the Eastern Mediterranean (Khafage et al 2019) and West Africa (Clotilde-Ba et al 1997). In the western Atlantic, it has been detected since the end of the 1980s, when Fausto-Filho (1987) first recorded the species in the littoral zone of Maranhão, Brazil. Later it was registered in 1988 in the Carolinas, Georgia, and Florida, USA (Fuller et al 2014), Venezuela (Altuve et al 2008), Colombia (Gómez-Lemos & Hernando-Campos 2008), Puerto Rico (Knott et al 2021), Cuba (Giménez et al 2014), Costa Rica (Alfaro-Montoya et al 2015) and Guatemala (Avalos 2015). This work provides updated information on reported sightings of P. monodon on the Mexican coast of the Gulf of Mexico and reports the smallest specimen found in the western Atlantic
