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 ...

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 ...

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.

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.

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,

Photoperiod-driven gene regulation in the brain of Chirostoma estor: endocrine, metabolic, and epigenetic insights [PDF]

open access: yesFrontiers in Endocrinology
IntroductionAquatic light environments are increasingly altered by human activity, yet the endocrine and molecular mechanisms enabling fish to cope with extreme photoperiods remain poorly understood.

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 ...

Enzymatic fish protein hydrolysates in finfish aquaculture: a review

open access: yesReviews in Aquaculture, Volume 13, Issue 1, Page 406-430, January 2021., 2021
Abstract In intensive farming systems, fish are held at high densities, which may increase stress, leading to susceptibility to diseases that result in economic losses. Therefore, effective feeding practices incorporating health‐promoting compounds such as proteins, hydrolysates and bioactive peptides that can stimulate the defence mechanisms of fish ...

Weighted fuzzy inference system for water quality management of Chirostoma estor estor culture

open access: yesAquaculture Reports, 2020
The increase in overfishing and pollution in Pátzcuaro Lake, Michoacán, México, has generated a severe problem in the endemic species that live there; especially the Chirostoma estor estor that has been threatened.
