Scanning Electron Microscopy of the Rainbow Trout (Salmo gairdneri Richardson) Spermatozoon
The scanning electron microscope was used to determine the morphology of the rainbow trout (Salmo gairdneri Richardson) spermatozoon. The spermatozoon is approximately 32 μm long and consists of a head, mitochondrial collar, and flagellum. The head is elongated and somewhat flattened. It has an antero posterior length of 3.1 μm and a maximum diameter of 1.6 to 2.2 μm. Mean antero-posterior length of the mitochondrial collar is 0.8 μm The collar encircles the flagellum but is separated from it. The flagellum ranges in length from 26 to31 μm and is divided into a principal piece and end piece. Cytoplasmic vesicles commonly are found in the anterior region of the flagellum
