The invention provides an artificial
seedling raising method for an outdoor ecological pond of Cromileptes altivelis with a
high survival rate. The artificial
seedling raising method comprises the following steps of step (1), preparation of a
seedling raising pond; step (2), treatment of newly-hatched fish fries before entering the pond; step (3), slowly putting the newly-hatched fish fries, the density is 10000 to 10500 / m3, the fish fries is 10 to 30 days old, feeding copepodid larvae, and adding 0.02 to 0.04mg / L mixed bait of
betaine and memhaden
meal; and feeding frozen
shrimp meat paste and compound feed during 30 days old to the end of seedling raising; step (4),
water quality regulation; performing seedling raising for 6 to 10 days, and adjusting the pond
water depth to be 2.0 to 2.3m; performing seedling raising for 11 to 20 days, replacing 4 to 10% of filtered
seawater every day and adjusting the
salinity to be 28 to 32; and performing seedling raising for 21 days until the endof the seedling raising, and adjusting the
salinity to be 27 to 30; and step (5), performing seedling emergence. According to the artificial seedling raising method for the outdoor ecological pond ofthe Cromileptes altivelis with the
high survival rate provided by the invention, the
survival rate and the growth quality of the fish fries are greatly improved, and an important basis is provided for the artificial breeding of the high-quality and high-efficiency Cromileptes altivelis in the later period.
