Abstract
Summary: The nuclei of spermatozoa from several species of trout, herring, sturgeon and salmon consist of nucleoprotamines only. The ratio of phosphorus to arginine almost reaches 1:1 in nucleoprotamine of trout, salmon and herring. Some of the phosphoric acid residues in nucleo-sturine are neutralized by other basic amino acids. The nucleic acid of the nuclei is exclusively of the desoxyribose type. Ribonucleic acid occurs in cytoplasm of the sperm only. The molecular weight of nucleoprotamine is about 1.3 × 106. One single nucleus of a certain trout species (Saibling) consists of 4.5 × 106 nucleoprotamine molecules as roughly calculated. Eggs of a trout species have been artificially fertilized, and from those eggs young fish could be raised which behaved and looked normally.
