“…Molecular evidence also brings new perspectives at the alpha taxonomy level. While recent taxonomic check lists estimate that the number of valid ariid species range from 125 to 136 ([ 15 , 21 ]; plus five more recent additions [ 42 - 44 ]), there are 53 species designated as inquirendae in the family (i.e., uncertain validity), the greatest number within the order Siluriformes [ 3 , 39 ]. The major difficulties in undertaking a comprehensive taxonomic study of the Ariidae are the overall similarity in external morphology, the widespread distribution of the group coupled with the high degree of species endemism, and the poor representation of species diversity in museums [see also [ 21 ]].…”

Background: Ariids or sea catfishes are one of the two otophysan fish families (out of about 67 families in four orders) that inhabit mainly marine and brackish waters (although some species occur strictly in fresh waters). The group includes over 150 species placed in ~29 genera and two subfamilies (Galeichthyinae and Ariinae). Despite their global distribution, ariids are largely restricted to the continental shelves due in part to their specialized reproductive behavior (i.e., oral incubation). Thus, among marine fishes, ariids offer an excellent opportunity for inferring historical biogeographic scenarios. Phylogenetic hypotheses available for ariids have focused on restricted geographic areas and comprehensive phylogenies are still missing. This study inferred phylogenetic hypotheses for 123 ariid species in 28 genera from different biogeographic provinces using both mitochondrial and nuclear sequences (up to ~4 kb).

“…Ninety‐one fish species from 27 families have been recorded in the Usumacinta River Basin, with the family Cichlidae the most prevalent group (26 species; Rodiles‐Hernández 2005). A new catfish family (Lacantunidae) discovered in the Lacantun River (Rodiles‐Hernández, Hendrickson, Lundberg & Humphries 2005), a new ariid species, Potamarius usumacintae Betancur‐R & Willink (Betancur‐R & Willink 2007) and a new cichlid species (Schmitter‐Soto 2007) might be indicators of the richness of the local aquatic fauna.…”

Subsistence fishing was surveyed in the communities of Nueva Esperanza and Loma Bonita of the Lacandon Forest in the Usumacinta River Basin of Chiapas, Mexico from March to August 2005. Thirty fish species, four turtles and two crustaceans were harvested. The most prevalent species in terms of biomass extracted were the pantano cichlid, Herichthys pearsei (Hubbs), grass carp, Ctenopharyngodon idella (Valenciennes), northern checkmark cichlid, Vieja intermedia (Gu¨nther), bigmouth sleeper, Gobiomorus dormitor Lacepe`de, machaca, Brycon guatemalensis Regan, and blue catfish, Ictalurus furcatus (Lesueur). Ten fishing gears were employed in four habitat types. Fishing patterns, fishing gears employed, species harvested, biomass extracted and catch rates differed between localities. The uniqueness of local fisheries should be considered in further studies and management policies for conservation of fish populations.

“…While smaller varieties of catfish, namely in the Cathorops genus, are found in most time periods, only during the Preclassic period does a larger species of catfish appear. Based on several large otoliths found in Middle Preclassic phases, the fish is comparable in terms of size and shape with large sea catfish (Ariopsis felis), but may in fact be the large Usumacinta catfish (Potamarius usumacintae; [67]).…”

“…Some of the snook (Centropomus sp.) bones and large catfish (Ariidae) remains may have been marine imports from the coast, but both fish are found in the Pasión river today [40,67]. There are also no stingray spines, which are ubiquitous at other Classic period sites in the lowlands, including nearby sites like Altar de Sacrificios [92] and Aguateca [90].…”

The Maya Preclassic to Classic transition observed through faunal trends from Ceibal, Guatemala

et al. 2020

It is well known that the development of the ancient Maya civilization had significant and long-lasting impacts on the environment. This study assesses a large collection of faunal remains (>35,000 specimens) recovered over a span of several kilometers in and around the archaeological site of Ceibal, Guatemala, in order to determine whether the composition of animal resources was continuous throughout the site's history between 1000 BC and AD 1200, or whether there were any changes that could be attributed to sociopolitical or environmental causes. Results show a steep uniform decline in the number of freshwater mollusks across the site that occurred during the Preclassic to Classic transition, when large region-wide political changes, including the development of more complex and centralized political organization, took place throughout the Maya region. Evidence of species introductions (e.g., turkeys from central Mexico and possibly the Dermatemys river turtle from the Isthmus of Tehuantepec) and variations in resource exchange (e.g. marine shells) over time indicate that Ceibal was one of likely many communities involved in long-distance animal exchange networks. The results of the faunal analysis at Ceibal show how the ancient Maya had a complex and ever-changing relationship with the local wildlife, with outcomes that can still be observed in the environment today.
