Fertilizing ability of short-term preserved spermatozoa Abant trout (Salmo trutta abanticus T, 1954)

Fertilizing ability of short-term preserved spermatozoa Abant trout (Salmo trutta abanticus

The objective of this experiment was to evaluate spermatological parameters and fertilizing ability of short term stored semen in different extenders from endemic Abant trout (Salmo trutta abanticus T,1954). Semen was collected from 30 adult males by the hand stripping method without anesthesia. Having determined the main spermatological properties (volume, motility, movement duration, concentr...

Morphological differences in the skin of marble trout Salmo marmoratus and of brown trout Salmo trutta.

Despite being genetically very closely related, the marble trout Salmo marmoratus and the brown trout Salmo trutta exhibit marked phenotypic differences, particularly with regard to skin pigmentation. Histological analysis of skin from the head and gill cover of differently aged individuals of the two species was carried out in order to characterize differences in skin structure. The basic stru...

Short-term genetic changes: evaluating effective population size estimates in a comprehensively described brown trout (Salmo trutta) population.

The effective population size (N(e)) is notoriously difficult to accurately estimate in wild populations as it is influenced by a number of parameters that are difficult to delineate in natural systems. The different methods that are used to estimate N(e) are affected variously by different processes at the population level, such as the life-history characteristics of the organism, gene flow, a...
