Benefits of technology

This new technology allows creating high-quality crops through controlled rearing techniques called genetic engineering or molecular biology methods. These improvements improve crop yields while reducing their chances of being lost during harvest due to factors like worm infestation (frostiness) or stress conditions such as water temperature changes.

Problems solved by technology

The technical problem addressed by this patented technology relates to improving the efficiency at which crops produce new types of seeds called gold rolls (or buckles). This requires researching how well these seals have developed over their lifespan during production on different species without causing harmful effects like reproductive failure due to lack of nutrients needed for optimal growth.

Embodiment 1

[0040] On May 8, 2015, 5 million healthy money fish with a body length of about 0.6 cm were placed in a 5-acre earth pond in the breeding base of Zhuhai Yucheng Fish Fry Farming Co., Ltd. Measured by 10,000 fish fry, 20 g of rotifers were fed every day, three times in the morning (8, 9, 10 o’clock) and afternoon (2, 3, 4 o’clock), and fed continuously for 7 days; from the 8th day, the feed The composition is 3g copepods plus 27g rotifers, and then add 3g copepods every day until the copepods are completely fed. The fed rotifers and copepods use gentian grass powder 30mg, yeast 30mg, and trypsin preparation 12mg, Bok cinnamon powder 18mg, aluminum silicate 108mg, sodium bicarbonate 180mg, lactic acid bacteria preparation 120mg soak for 10 minutes; when the body length is about 1.5cm, the feed composition is 6g powdered seawater fish feed mixed with 54g copepods, increase every 3 days 6g powdered seawater fish feed, until the powdered seawater fish feed is completely fed, add th...

Embodiment 2

[0042] On December 27, 2015, 1 million healthy yellowfin bream splashes with a body length of 0.6 to 0.7 cm were placed in a 3-acre earth pond at the breeding base of Zhuhai Yucheng Fry Breeding Co., Ltd. Measured by 10,000 fish fry, feed 25 g of rotifers per day, three times in the morning (8, 9, 10 o’clock) and three times in the afternoon (2, 3, 4 o’clock), and feed continuously for 7 days; from the 8th day, the feed The composition is 4g copepods plus 36g rotifers, and then add 4g copepods every day until the copepods are completely fed. The fed rotifers and copepods use gentian grass powder 40mg, yeast 40mg, pancreatin preparation 16mg, Bok cinnamon powder 24mg, aluminum silicate 144mg, sodium bicarbonate 240mg, lactic acid bacteria preparation 160mg soak for 10 minutes; when the body length is about 1.5cm, the feed composition is 8g powdered seawater fish feed mixed with 72g copepods, every 3 days Add 8g of powdered seawater fish feed until the powdered seawater fish fee...

Embodiment 3

[0044]On March 8, 2015, 5 million healthy basket fish with a body length of about 0.4cm were placed in a 5-acre earth pond at the breeding base of Zhuhai Yucheng Fish Fry Farming Co., Ltd. Measured by 10,000 fish fry, feed 20 g of rotifers per day, three times in the morning (8, 9, 10 o'clock) and three times in the afternoon (2, 3, 4 o'clock), and feed them continuously for 7 days; from the 8th day, the feed The composition is 3g copepods plus 27g rotifers, and then add 3g copepods every day until the copepods are completely fed. The fed rotifers and copepods use gentian grass powder 36mg, yeast 36mg, and pancreatic enzyme preparation 24mg, Bok cinnamon powder 24mg, aluminum silicate 120mg, sodium bicarbonate 240mg, lactic acid bacteria preparation 180mg, soak for 10 minutes; when the body length is about 1.5cm, the feed composition is 6g powdered seawater fish feed mixed with 54g copepods, increasing every 3 days 6g of powdered seawater fish feed, until the powdered seawater...

Abstract

The invention relates to a breeding method for increasing survival rate of fish larvae. The method specifically comprises the following steps: (S1) putting the fish larvae into a soil pond, then, carrying out feeding for 3 times separately in the morning and afternoon according to the daily feeding amount of 18g to 22g of rotifers per ten-thousands of fish larvae, and carrying out feeding at the interval of 1 hour for 7 continuous days; (S2) from the eighth day, increasing 10% to 15% of Copepoda every day so as to gradually replace the rotifers until the rotifers are completely replaced, and carrying out feeding according to the daily feeding amount of 30g to 50g of the Copepoda per ten-thousands of the fish larvae at the feeding times and time interval in the step (S1); (S3) after the body length of each fish fry is greater than 1.5cm, increasing 10% to 15% of powdery seawater fish feed every 3 days so as to gradually replace the Copepoda until the Copepoda is completely replaced, and carrying out feeding according to the daily feeding amount of 50g to 80g of the powdery seawater fish feed per ten-thousands of the fish fries at the feeding times and time interval in the step (S1); and (S4) after the body length of each fish fry is greater than 2.5cm, increasing 10% to 15% of zero feed every day so as to gradually replace the powdery seawater fish feed until the powdery seawater fish feed is completely replaced, and carrying out feeding according to the daily feeding amount of 80g to 100g of the zero feed per ten-thousands of the fish fries at the feeding times and time interval in the step (S1).
