Zootechnical Brown Trout (Salmo trutta L. 1758) Ovarian Fluid Fails to Upregulate the Swimming Performances of Native Mediterranean Brown Trout (Salmo cettii Rafinesque, 1810) Sperm in the Biferno River

open access: yesFishes, 2023
In external fertilizer fish, ovarian fluid (OF) seems to play a key role in fertilization success, improving spermatozoa swimming performance. These OF/sperm interaction mechanisms are frequently species-specific and/or population-specific and could ...

A hierarchical model to estimate the abundance and biomass of salmonids by using removal sampling and biometric data from multiple locations [PDF]

open access: yes, 2010
We present a Bayesian hierarchical model to estimate the abundance and the biomass of brown trout (Salmo trutta fario) by using removal sampling and biometric data collected at several stream sections.

The use of prevalence as a measure of lice burden: a case study of Lepeophtheirus salmonis on Scottish Atlantic salmon, Salmo salar L., farms [PDF]

open access: yes, 2009
This study investigates the benefits of using prevalence as a summary measure of sea lice infestation on farmed Atlantic salmon, Salmo salar L. Aspects such as sampling effort, the relationship between abundance and prevalence arising from the negative ...

Field and laboratory approaches to assess "estrogen disruption" in the brown trout "Salmo trutta" [PDF]

open access: yes, 2008
In recent years, the annual catches of brown trout and other native fish species have been declining in Switzerland about 60%. One hypothesis was that the reduced catch is linked to estrogen-active chemicals entering the aquatic environment via waste ...
