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.

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.

Microbiota attached to and encapsulated by granulomas dissected from tilapia spleen: A case report

Aquaculture, Fish and Fisheries, Volume 3, Issue 1, Page 96-101, February 2023., 2023
Graphical Abstract Abstract Granulomatous diseases are caused mainly by bacterial infections that the fish immune system cannot eliminate; consequently, pathogens are encapsulated, forming a complex structure where immune cells participate in containing the damage.

The North American Freshwater Migratory Fish Database (NAFMFD): Characterizing the migratory life histories of freshwater fishes of Canada, the United States and Mexico

Journal of Biogeography, Volume 49, Issue 6, Page 1193-1203, June 2022., 2022
Abstract Aim Migratory freshwater fishes are those that must access discrete habitats to complete their life cycles. Freshwater fish migrations occur around the world and provide numerous ecosystem services for humans and natural systems; however, many migratory species are in decline globally.

Uranium in the surrounding of San Marcos-Sacramento River environment (Chihuahua, Mexico). [PDF]

ScientificWorldJournal, 2012
The main interest of this study is to assess whether uranium deposits located in the San Marcos outcrops (NW of Chihuahua City, Mexico) could be considered as a source of U‐isotopes in its surrounding environment. Uranium activity concentrations were determined in biota, ground, and surface water by either alpha or liquid scintillation spectrometries ...

Community dynamics of estuarine forage fishes are associated with a latitudinal basal resource regime

Ecosphere, Volume 13, Issue 5, May 2022., 2022
Abstract Forage fishes are an important component of marine, estuarine, and aquatic food webs that facilitate the transfer of energy and nutrients from primary producers to upper trophic levels. Previous studies of forage fishes have focused primarily on pelagic planktivorous species in pelagic environments.

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.

Episodic disturbances drive nutrient dynamics along freshwater‐to‐estuary gradients in a subtropical wetland

Ecosphere, Volume 9, Issue 6, June 2018., 2018
Abstract Wetlands are biogeochemically active ecosystems where primary production and respiration interact with physico‐chemical conditions to influence nutrient availability across spatio‐temporal scales. The effect of episodic disturbances on water quality dynamics within wetlands is relatively unknown, especially in large oligotrophic wetlands such ...
