Parent Navodon septentrionalis reproduction maturing promoting bait and preparation method thereof

Abstract

The invention discloses parent Navodon septentrionalis reproduction maturing promoting bait and a preparation method thereof. The parent Navodon septentrionalis reproduction maturing promoting bait comprises the following components in percentage: 8 to 13 percent of clam worm, 8 to 13 percent of oyster meat, 8 to 13 percent of mussel meat, 25 to 35 percent of artificial compound feed powder, 0.2 to 0.4 percent of vitamin C, 0.1 to 0.2 percent of vitamin E, 0.6 to 0.8 percent of immune polysaccharide, 0.2 to 0.4 percent of Coptis chinensis, Scutellaria baicalensis and golden cypress powder or rheum officinale Coptis chinensis, Scutellaria baicalensis and golden cypress powder, 0.2 to 0.4 percent of spirulina powder, 0.2 to 0.4 percent of lecithin, 8 to 13 percent of Trachypenaeus curvirostris, 8 to 13 percent of leftovers from pectinid cylinder processing and 5 to 10 percent of residual internal organs from urechis unicinctus processing. The bait can satisfy the nutrient demands of parent fish, improve the developmental rate of sexual gland of parent fish, promote the synchronous development of sexual gland, improve egg laying amount and ovum quality of parent fish and lay a good foundation for the scale seedling breeding of Navodon septentrionalis.

Description
