Invasive cichlids (Teleostei: Cichliformes) in the Amacuzac River, Mexico: Implications for the behavioral ecology of the native Mexican mojarra Amphilophus istlanus

Water Biology and Security, 2023
The introduction of species is a leading cause of biodiversity loss and habitat alteration. Several species have invaded Mexican freshwater ecosystems, adversely affecting native fishes.

The effects of temperature, body weight and hypoxia on the oxygen consumption of the Mexican mojarra, Cichlasoma urophthalmus (Günther)

Aquaculture Research, 1986
. The oxygen consumption rate of the Mexican cichlid, Cichlasoma urophthalmus Gunther, was determined using closed-circuit respirometry at 20,25,30 and 36°C over a weight range of l·91–116g. Oxygen consumption rates ranged from 31 to 4500mg/kg/h and were slightly higher than for other cichlid species reported.

Determination of morphometric parameters in the Mexican mojarra, Cichlasoma urophthalmus (Günther), for the design and construction of box graders

Aquaculture Research, 1990
Abstract. The morphometric relationships, standard length-weight, standard length-width and weight-width for Cichlasoma urophthalmus (Gunther) in the weight range 0.78-262g were: log10 weight =−4.35 + 2.95 × (log10 standard length); log10 width =−0.73 + 0 99 × (log10 Standard length) and log10 width = 0.74 + 0.33 × (log10, weight). Two box graders were

Evaluation of Larval Growth and Survival in Mexican Mojarra, Cichlasoma urophthalmus, and Bay Snook, Petenia splendida, Under Different Initial Stocking Densities

Journal of the World Aquaculture Society, 2009
Abstract Two experiments were conducted to evaluate the initial stocking density in larvae of Bay snook, Petenia splendida, and Mexican mojarra, Cichlasoma urophthalmus, using a recirculation system. Five initial stocking densities (0.5, 1, 5, 10, and 20 larvae/L) were evaluated by triplicate for 45 d.

Morphological and molecular evidence for a new rhabdochonid species, Rhabdochona (Nematoda: Rhabdochonidae), parasitizing Eugerres mexicanus (Perciformes: Gerreidae), from the Lacantún River in the Biosphere Reserve of Montes Azules, Chiapas, Mexico

Revista Mexicana de Biodiversidad, 2021
A new nematode species, Rhabdochona juliacarabiasae sp. n. is described from specimens recovered from the intestine of the freshwater Mexican mojarra, Eugerres mexicanus (Steindachner) (Gerreidae) captured in the Lacantún River, Chiapas, Mexico ...

Climate change linked to functional homogenization of a subtropical estuarine system. [PDF]

Ecol Evol, 2022
Distribution shifts in fish species, which have been linked to increasing temperatures, have led to subsequent increases in fish species diversity. In our study, increasing species diversity led to increased functional richness but decreased functional dispersion.

Eugerres castroaguirrei González-Acosta et Rodiles-Hernández, 2013 is a junior synonym of Eugerres mexicanus (Steindachner, 1863) (Actinopterygii: Perciformes: Gerreidae) [PDF]

Acta Ichthyologica et Piscatoria, 2015
Background. The Lacandon mojarra, Eugerres castroaguirrei González-Acosta et Rodiles-Hernández, 2013, was described from the Grijalva–Usumacinta River basin (Mexico). According to the diagnosis E. castroaguirrei differs from the only other freshwater

Ingestion Rate, Prey Selectivity, and Growth of Larval Vieja zonata (Teleostei: Cichlidae) Co-Fed Rotifers with Cladocerans. [PDF]

Aquac Nutr
The study of fish larval nutrition is important as dietary requirements change significantly with growth. Vieja zonata is a cichlid species that is endemic to Mexico. In this study, we investigated the ingestion rate, prey selectivity, and growth of V. zonata larvae that were fed on prey cultured with and without probiotics.
