ORDINOLA-ZAPATA, Alberto et al. Introduced and potentially invasive fish in the departments of the North Coast of Peru. A systematic review. Figempa [online]. 2025, vol.19, n.1, e7318.  Epub 24-Jan-2025. ISSN 2602-8484.  https://doi.org/10.29166/revfig.v19i1.7318.

Introduced fish can threaten aquatic biodiversity. Peru is a megadiverse country; its northern coast (Tumbes, Piura, Lambayeque, and La Libertad) exhibits greater fish diversity than its central and southern regions. In this area, introduced species exist; however, no research has been found that consolidates data on them. The aim of this research was to prepare a systematic review of introduced and potentially invasive fish in the northern coast of Peru. Following the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) from 2020, 2,665 documents were obtained from Scopus, WoS, ScienceDirect, SciELO, PubMed, and Google Scholar. After removing duplicate documents and applying inclusion and exclusion criteria, six documents were selected. Eight additional documents were obtained from other sources. A total of 12 introduced species were reported: common carp (Cyprinus carpio), gambusia (Gambusia affinis), guppy (Poecilia reticulata), swordtail (Xiphophorus hellerii), tilapia (Coptodon rendalli), blue tilapia (Oreochromis aureus), Mozambique tilapia (Oreochromis mossambicus), Nile tilapia (Oreochromis niloticus), wami tilapia (Oreochromis urolepis), cobia (Rachycentron canadum), rainbow trout (Oncorhynchus mykiss), and hypostomus (Hypostomus sp.). Of these, five species were cichlids and three were poeciliids; eleven species were found in freshwater, five in mangroves, and two in the sea. Tumbes recorded the highest number of waterbodies with introduced species, Piura recorded the highest number of species (eight), while Lambayeque reported only one species in a waterbody. Seven species (common carp, gambusia, guppy, tilapias - blue, Mozambique, and Nile - and rainbow trout) have a high invasive potential, as they are among the 100 worst invasive species in Europe or worldwide. The evaluated documents have only reported the presence of introduced species without delving into their impact on ecosystems; therefore, further research in this direction would be advisable.
