Persisting at the Edge of Ecological Collapse: The Impact of Urbanization on Fish and Amphibian Communities From Lake Xochimilco

Environmental DNA, Volume 7, Issue 4, July–August 2025.
ABSTRACT Freshwater ecosystems are globally threatened by habitat loss, pollution, and invasive species, all of which are particularly acute in urban areas. To assess the impacts of urbanization on freshwater biodiversity—specifically the effects of alien species on native primary aquatic vertebrates—we investigated the World Heritage Site, Lake ...

Evaluating Environmental Predictors of Fish Community Composition in a Semi‐Arid River System Using a Model‐Based Approach

Ecology of Freshwater Fish, Volume 34, Issue 3, July 2025.
ABSTRACT Understanding how the environment shapes species distribution and affects biodiversity patterns is important in ecology and conservation. Environmental stressors like climate change and anthropogenic impacts may lead to a significant decline in aquatic biodiversity.

Analysis of morphometric and meristic characteristics of three cichlid species in central Iraq: farmed and wild

Oceanological and Hydrobiological Studies
This study is designed to assess morphological dissimilarities between aquaculture and feral groups of three cichlid fish species, Coptodon zillii (Gervais, 1848), Oreochromis aureus (Steindachner, 1864), and Oreochromis niloticus (Linnaeus, 1758). Feral

Effects of Size Grading and Different Stocking Size Compositions on Growth Performance of Hybrid Tilapia (Oreochromis niloticus♀ X Oreochromis aureus♂) Juvenile

Turkish Journal of Agriculture: Food Science and Technology, 2020
In aquaculture, size grading application is made in order to protect against the disadvantages caused by the length difference between fish. Via this activity, large and small individuals separate each other during the feeding period.

Importance of Minerals and Their Bioavailability in Boosting Aquaculture: A Systematic Review

Aquaculture, Fish and Fisheries, Volume 5, Issue 3, June 2025.
ABSTRACT Fish like other terrestrial animals, have specific requirements for individual minerals that support the growth and maintenance of normal fish health and other biological functions among different cultured fish species. These minerals can be either macro or micro minerals that are supplied to the fish body through diets or absorbed from their ...

Comparative transcriptome analysis reveals potential regulatory mechanisms in response to changes in physiological functions in Oreochromis aureus under salinity stress

Aquaculture Reports
Oreochromis aureus is an economically valuable fish species, but its domestication in saline environments remains unexplored, with limited reports on how salinity stress affects its physiological functions and acclimation-related mechanisms.
