Impacts of Salmonid Fish Production on River Water Quality: A Critical Appraisal of the Evidence

open access: yesReviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT Rivers are recognised as providing valuable goods and services to society, and as hotspots of global biodiversity. Fish farming is an economically important activity associated with river systems; however, the effects of this industry on river health are not entirely understood. Studies evaluating interactions between freshwater fish farms and

Early Nutritional Programing: Unlocking the Potential of Fish for Sustainable Aquaculture

open access: yesAquaculture Nutrition, Volume 2026, Issue 1, 2026.
Nutritional programing, which explores the link between early nutritional conditions and their long‐term effects on animals, is a developing field within fish biology. Suboptimal nutritional status during early life is strongly associated with a higher risk of metabolic consequences later in life, including permanent growth retardation, impaired neural

Effects of flow regime on the young stages of Salmonid fishes. Conclusions based on results for 1977-1981 [PDF]

open access: yes, 1981
Rivers in Teesdale and its fish population have been monitored for several years. This report briefly describes the life cycle of British salmonid fishes and indicates the main ways in which this life cycle is influenced by discharge and related effects.

Investigation and characterization of the 16S rRNA gene in the Salmo trutta fario and Salmo trutta caspius

open access: yesEgyptian Academic Journal of Biological Sciences, B. Zoology, 2013
16S rRNA gene in the salmo trutta fario and Salmo trutta caspius has been polymerized, characterized and compared with within and between of salmonids species. The full lengths of 16S rRNA gene in species of salmons were sequenced approximately 1.7 kb and deposited in GenBank. We designed one pair of primer for amplification of 16S rRNA gene in species

Acid precipitation and its effects on aquatic systems in the English Lake District [PDF]

open access: yes, 1983
There is no evidence of an increase in the acidity (lower pH or alkalinity) of water-bodies in the Lake District over the last 50 years. Brown trout occur in acid streams and upland tarns where pH is 4.5-5.2 throughout the year.
