Process for increasing the biological resistance of fishes at the early growth stages

摘要

The invention refers to pisciculture, in particular to a process for increasing the biological resistance of fishes at the early growth stages.Summary of the invention consists in treating the fecundated fish spawn with a biologically active substance, in the capacity of which it is used the aqueous solution of furostanol glycoside in the concentration of 4…5 mg/L, with the general formula:wherein: Glc is glucose;Gal is galactose.The result of the invention consists in increasing the spawn resistance, in a more synchronic development of the embryos and in a 5…8% increase of the resistant three-day larvae hatch.
