The invention discloses a method for cultivating
epinephelus septemfasciatus
offspring seeds, which comprises the steps of: culturing the
offspring seeds under the conditions that the
salinity is 28+ / -2, the
water temperature is 19+ / -2 DEG C, the pH value is 8+ / -0.3 and the dissolved
oxygen is more than 6mg / l, controlling the
seedling distributing density to be 8000-15000 / M<3>; before newly hatched larvae enter a
pool, putting a composite bacterium (
photosynthetic bacterium and nitrobacterium) according to the concentration of 2ppm, adding 0.5ppm of composite bacterium and 1ppm of
shrimp feedevery day after 5 days, adding 1ppm of composite bacterium and 1ppm of
shrimp feed every day after 25 days, and stopping adding the composite bacterium and the
shrimp feed after 50 days; illuminatingthe newly hatched larvae at 2000-4000lx until the newly hatched larvae grow to the 10th day, illuminating the
epinephelus septemfasciatus growing from the 11th day to the 30th day at 1000-3000lx and illuminating the
epinephelus septemfasciatus growing from the 31st day to the 60th day at 500-1000lx; after the newly hatched larvae enter the
pool, sucking and removing pollutants at the bottom of the
pool at the beginning of the 30th day; feeding the newly hatched larvae growing from the 4th day to the 7th day SS (Som
Somatostatin) type wheel animalcule and hardly developing before the wheel animalcule is fed to the larvae, wherein
larva feed comprises the SS small wheel animalcule and common wheel animalcule; and feeding the common wheel animalcule in the newly hatched larvae growing from the 6th day to the 20th day, and developing newly hatched larvae through
chlorella pyrenoidosa. The invention has the advantages of reasonable operation process and stable result, and is suitable for culturing cold temperate epinephelus septemfasciatus seeds.
