Broodstock Selection Strategies to Control Blackspot Blotches Inheritance in Hybrid Red Tilapia (Oreochromis spp) for Sustainable Fingerling Production

Aquaculture, Fish and Fisheries, Volume 5, Issue 5, October 2025.
ABSTRACT Red tilapia is an increasingly important aquaculture species due to its rapid growth and high consumer preference. However, variation in pigmentation, particularly blotched phenotypes, reduces market value and uniformity of fingerlings. This study assessed the effects of broodstock pigmentation phenotype on progeny survival, growth performance,

Fish Allergenicity Ladder and Parvalbumin Epitopes for Predicting Clinical Cross‐Reactivity and Reintroduction in Chinese Population

Allergy, Volume 80, Issue 10, Page 2810-2823, October 2025.
Clinical history including self‐reported history and oral food challenge outcome, and sIgE sensitization profile of 200 subjects with suspected fish allergy was analyzed to construct a 3‐step fish allergenicity ladder. The allergenicity ladder was positively linked to the relative parvalbumin content of fish muscle but not to differences in the IgE ...

Larger Fish Have Larger Brains With More Neurons Across but Not Within Cohorts Raised in Different Growth Conditions

Journal of Comparative Neurology, Volume 533, Issue 9, September 2025.
Teles et al. propose a model of brain evolution that explains how come fish with larger bodies have larger brains with more neurons across cohorts raised in different growth conditions, while individuals within a cohort do not, mimicking the different findings across and within species, respectively.

Environmental DNA Reveals the Fish Community Structure Exhibited Instability and Trend of Miniaturization in the Xijiang River Basin of the Guizhou

Ecology and Evolution, Volume 15, Issue 9, September 2025.
Monitoring of fish communities is of great significance for the management and sustainability of river ecosystems. Environmental DNA (eDNA) metabarcoding technology has been demonstrated to be a highly sensitive biomonitoring tool. Nevertheless, it has seldom been tested in mountainous rivers within the geographically complex Karst region.
