Resumen: "A systematic checklist is presented for the marine
estuarine fishes of Chiapas, Mexico, including notes on their
zoogeography and conservation status. The checklist includes
379 species, two classes, 30 orders, 91 families, and 207 genera.
Actinopterygii is themost diverse class (323 species, 181 genera,
72 families, and 23 orders), while Chondrichthyes (56 species,
26 genera, 19 families, and seven orders) is the least diverse class.
Perciformes is the richest order (175 species, 98 genera, and 32
families), including seven families representing 32.2% of the
total fish diversity reported here: Sciaenidae (25 species),
Carangidae (21), Gobiidae (20), Haemulidae (14),
Epinephelidae (11), Dactyloscopidae (10), and Gerreidae (10).
Based on a taxonomical review of specimens in fish collections
and literature-verified records, the list is composed of marinestenohaline
(46.7%), marine-euryhaline (48.8%), primary freshwater
(1%), secondary freshwater (2.6%), and diadromous
(0.2%) species. The ichthyofauna showed greater zoogeographic
affinity to theMexican (81.5%) and Panamic (80.5%) provinces,
while 48 species are circumtropical, four amphipacific, five
amphiamerican, and one exotic (Oreochromis niloticus). Based
on the IUCN Red List, 259 species are of BLeast Concern^, 18
are BNear Threatened^, 11 are BVulnerable^, two are BCritically
Endangered^ (Pristis pectinata and P. pristis), and one is
BEndangered^ (Rhincodon typus)"
