Bioaccumulation of PCBs and PBDEs in Fish from a Tropical Lake Chapala, Mexico [PDF]

open access: yesToxics, 2021
Lake Chapala is the largest natural freshwater reservoir in Mexico and the third largest lake in Latin America. Lakes are often considered the final deposit of polluting materials; they can be concentrated in the organisms that inhabit them, the water ...

Loss of gut microbial diversity in the cultured, agastric fish, Mexican pike silverside (Chirostoma estor: Atherinopsidae) [PDF]

open access: yesPeerJ, 2022
Teleost fish are the most diverse group of extant vertebrates and have varied digestive anatomical structures and strategies, suggesting they also possess an array of different host-microbiota interactions.

Evaluation of the Optimal Protein Required in Granulated Microdiets for Rockfish (Sebastes schlegeli) Larvae. [PDF]

open access: yesAquac Nutr, 2022
Protein is an essential nutrient that supports fish growth, and the inadequacy in formulating their diets with an optimum protein level can deteriorate their growth performance. The protein requirement in granulated microdiets was estimated for rockfish (Sebastes schlegeli) larvae.

Genome-wide species delimitation analyses of a silverside fish species complex in central Mexico indicate taxonomic over-splitting [PDF]

open access: yesBMC Ecology and Evolution, 2022
Background Delimiting species across a speciation continuum is a complex task, as the process of species origin is not generally instantaneous. The use of genome-wide data provides unprecedented resolution to address convoluted species delimitation cases,

Dietary prebiotics and synbiotics modulate gut microbiota and improve growth performance of Mexican pike silverside Chirostoma estor [PDF]

open access: yesPeerJ
Aquaculture is the fastest-growing food production sector worldwide and is vital for a sustainable animal protein supply. However, optimizing fish performance in captivity remains a major challenge, requiring functional diets that support a healthy ...

Phylogeography of the Mesa Silverside fish Chirostoma jordani (Woolman, 1894) throughout the Mexican Plateau [PDF]

open access: yesPeerJ
Background Understanding the processes that influence distribution of organisms is a major goal in evolutionary biology. Speciation in freshwater fishes is mainly associated with the “island-like” model of evolution, in which the formation of land ...

Diversification of substrate specificities in teleostei Fads2: characterization of Δ4 and Δ6Δ5 desaturases of Chirostoma estor[S]

open access: yesJournal of Lipid Research, 2014
Currently existing data show that the capability for long-chain PUFA (LC-PUFA) biosynthesis in teleost fish is more diverse than in other vertebrates.

High levels of docosahexaenoic acid are present in eight New World silversides (Pisces: Atherinopsidae) [PDF]

open access: yesNeotropical Ichthyology, 2020
Docosahexaenoic acid (DHA) is the most critical and least available omega-3 fatty acid in the Western human diet. Currently, the source of omega-3 long chain polyunsaturated fatty acids (LC-PUFA) is mainly dependent on wild fisheries, making this ...
