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 ...
