Determination of semen quality of the rainbow trout, Oncorhynchus mykiss, by sperm motility, seminal plasma parameters, and spermatozoal metabolism
TL;DR: The relationships between semen fertilization capacity and sperm motility, seminal plasma composition and sperm metabolism in the rainbow trout, Oncorhynchus mykiss, is investigated to find out biomarkers for semen quality.

Effect of bisphenol A on maturation and quality of semen and eggs in the brown trout, Salmo trutta f. fario
TL;DR: The tested BPA concentrations affected the percentage of ovulated females and the time point of ovulation, and no effect was observed on the quality of eggs.

Sperm metabolism of the telost fishes Chalcalburnus chalcoides and Oncorhynchus mykiss and its relation to motility and viability.
TL;DR: In this paper, the influence of metabolic inhibitors, substrates, coenzymes, and oxygen concentrations on spermatozoal parameters during motility and during immotile incubation was studied, the respiration rate was characterized, representative metabolite levels were measured, and the results were compared with Oncorhynchus mykiss (Salmonidae).

The effect of 4-nonylphenol on semen quality, viability of gametes, fertilization success, and embryo and larvae survival in rainbow trout (Oncorhynchus mykiss).
TL;DR: In vivo and in vitro effects of environmental relevant concentrations of 4-nonylphenol on the reproduction of rainbow trout and the development of embryos and larvae at the end of yolk sac stage was affected, while sperm density, sperm motility and sperm fertility were not affected.

Effect of 17β-estradiol on gamete quality and maturation in two salmonid species
TL;DR: In rainbow trout and grayling also the sperm motility pattern was affected by 17beta-estradiol exposure, and the egg viability changed in a similar way as in the control indicating that egg overripening processes were not influenced by 17 beta-ESTradiol.
