Comparison of three staining techniques for the morphometric study of rainbow trout (Oncorhynchus mykiss) spermatozoa.
This study was designed to compare the performance of the kits Diff-Quick, Hemacolor and Spermac for staining the spermatozoa of rainbow trout. Automated sperm morphology analysis (ASMA) was performed using two image analysis programs to determine the sperm measurements: head size (length, width, area and perimeter), shape (ellipticity, rugosity, elongation and regularity) and tail length. Diff...
متن کاملMorphometric and biochemical characteristics of ventricular hypertrophy in male rainbow trout (Oncorhynchus mykiss).
We examined the morphometric and biochemical effects of ventricular hypertrophy in male rainbow trout (Oncorhynchus mykiss) during sexual maturation. Our investigation focused on characterizing the growth of ventricular layers, on cardiomyocyte dimensions (length, cross-sectional area and cell volume) and on the activities of enzymes involved in intermediary metabolism. Relative ventricle mass ...
متن کاملEffect of prebiotic of Behsam on growth, feeding efficiency and and body composition of rainbow trout (Oncorhynchus mykiss) juvenile
To investigate the effect of dietary supplementation of Cell wall of Saccharomyces cerevisiae on growth performance and carcass composition of rainbow trout juvenile, an experiment was carried out on 600 pieces of Oncorhynchus mykiss with averaged mean weight 18±2 g for 45 days. This experiment conducted in a completely random design with four treatments which contain triplicates. Three levels ...
