Metabolism response mechanism in the gill of Oreochromis mossambicus under salinity, alkalinity and saline-alkalinity stresses

open access: yesEcotoxicology and Environmental Safety, 2023
Saline-alkalinity is one of the important ecological parameter that has an impact function on the physiological metabolism, osmoregulation, survival, growth, development and distribution of teleost fish.

Stressor‐ and Tissue‐Specific Regulation of the Corticotropin‐Releasing Factor System Across Epithelial Tissues in Rainbow Trout

open access: yesThe FASEB Journal, Volume 40, Issue 17, 15 September 2026.
The gill and intestinal corticotropin‐releasing factor (CRF) systems in rainbow trout are differentially regulated by immune, osmotic, and nutritional stressors. Seawater transfer suppressed gill CRF system transcription and induced time‐dependent changes in the middle intestine. An immune challenge (vaccination) altered only intestinal CRF expression.

Reticuloendothelial system of defense in Oreochromis mossambicus (Peters) [PDF]

open access: yes, 2003
The reticuloendothelial system (RES) was studied in vivo in Oreochromis mossambicus by injecting colloidal carbon particles. Histological and cytological examination of the organs from 2 hours to day 10 after injection revealed that the major organs ...

Male urine signals social rank in the Mozambique tilapia (Oreochromis mossambicus) [PDF]

open access: yes, 2007
Background The urine of freshwater fish species investigated so far acts as a vehicle for reproductive pheromones affecting the behaviour and physiology of the opposite sex. However, the role of urinary pheromones in intra-sexual competition has received

FishChip: Development of a High‐Throughput qPCR Assay for Freshwater Fish eDNA Quantification and Its Comparison With Droplet Digital PCR

open access: yesMolecular Ecology Resources, Volume 26, Issue 6, August 2026.
ABSTRACT Quantitative monitoring of fish using environmental DNA (eDNA) typically relies on quantitative real‐time PCR (qPCR) and droplet digital PCR (ddPCR), yet both methods are constrained in throughput, making it difficult to meet the demands of basin‐scale surveys.

Fish welfare in a changing world: New developments and current challenges

open access: yesJournal of Fish Biology, Volume 109, Issue 2, Page 650-692, August 2026.
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...
