Mexican Freshwater Fish: Identifying Conservation Priorities and High‐Risk Areas for Fisheries Under Climate Change

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 5, May 2026.
ABSTRACT Freshwater fish are essential components of aquatic ecosystems, providing key ecological functions and supporting livelihoods. Climate change poses a significant threat to freshwater biodiversity; consequently, both its conservation and the food security it sustains may be at risk.

Intraspecific karyotypic variation in the silverside fish Chirostoma humboldtianum (Atheriniformes: Atherinopsidae)

open access: yesHidrobiológica, 2016
Within its genus, Chirostoma humboldtianum is one of the species with the widest distribution, inhabiting lake and pond environments along the Lerma-Santiago basin in the Mexican Plateau. Although the species is of great ichthyological, economic, and cultural relevance, factors related to human activity such as habitat loss, pollution, overfishing, and

The Abrupt and Persistent Decline in Recruitment Success in Northeast Arctic Cod: A Review of Probable Causes

open access: yesFish and Fisheries, Volume 27, Issue 3, Page 643-659, May 2026.
ABSTRACT Most of the previously large cod stocks in the North Atlantic are depleted to very low levels. A notable exception has been the Northeast Arctic cod inhabiting the Barents Sea. This cod stock reached a record high level around 2013, but since then has declined sharply, with older fish being fished out and few new recruits entering the stock ...

Can larvae of a marine fish adapt to ocean acidification? Evaluating the evolutionary potential of California Grunion (Leuresthes tenuis)

open access: yesEvolutionary Applications, Volume 12, Issue 3, Page 560-571, March 2019., 2019
Abstract Ocean acidification can reduce the growth and survival of marine species during their larval stages. However, if populations have the genetic capacity to adapt and increase their tolerance of low pH and high pCO2 levels, this may offset the harmful effects of ocean acidification.

Comparing Aquatic Environmental DNA Collection Methods Across a Diel Cycle in a Lotic System

open access: yesEnvironmental DNA, Volume 8, Issue 2, March/April 2026.
Water samples were collected over 25 h from the Tangipahoa River, Louisiana, using active and passive environmental DNA methods to detect fish assemblages. Active sampling involved collecting water samples at hourly intervals for 25 h, whereas passive sampling deployed a stationary filter for 25 h.

Changes in Fish Communities of Lake Ontario Coastal Wetlands before and after Remedial Action Plans

open access: yesInternational Scholarly Research Notices, Volume 2011, Issue 1, 2011., 2011
We conducted a change‐detection analysis to determine if improvements in the habitat quality of coastal wetlands could be attributed to Remedial Action Plans (RAPs) of Lake Ontario. We used a 5‐km buffer relative to each recent site to “resample” an existing database of spawning/nursery habitat from the early 1980s to derive a “historic” species list ...

The Use of Chloride, Citric and Ascorbic Acid Dip and Packaged Film to Extend the Shelf Life of Pejerrey (Odonthested bonaerensis) during Storage at Different Temperatures [PDF]

open access: yes, 2014
The objective of this study was to analyze the effect of chloride, citric and ascorbic acid dip treatments in conjunction with two types of packaging films (with high and low gas permeability) on microbial growth in samples of pejerrey fillets ...
