On the basis of the embodiment 3, in the step (2), the pH value of the seawater is adjusted to 7-8, and the salinity is 13-15 per mill, specifically, the seawater is filtered, the filtering material is prepared from tourmaline powder, graphite flakes, macroporous resin, chitosan and activated carbon, the seawater is replaced for 5-7 days after the fry is put into the pond for the first time, the seawater is replaced every 20-25 days after the seawater is replaced for the first time, the seawater depth in the fish pond is kept to be 0.8-0.9 m, the pH value is adjusted to 7-8, and the salinity is 13-15 per mill.

Comparative example 3

In addition to example 3, in the step (4), the feed for the goldfish is replaced by a commercial feed (Tongwei fish feed), specifically, cabbage leaves, bait and the commercial feed are put in, and the mass ratio of the bait to the commercial feed is 0.5: 2: 7 cabbage leaves, bait and commercial feed; 15-30 days, the feeding mass ratio is 0.5: 4: 3, cabbage leaves, bait and commercial feed; and in the period from 30 days to the fishing period, the feeding mass ratio is 0.5: 8: 5, cabbage leaves, bait and commercial feed.

Test examples

The method comprises the steps of culturing in a harbor area of a new village in Lingshui county of Hainan province, wherein the area of a fishpond is 30 square meters, culturing in each of examples 1-6 and comparative examples 1-3 by using one fishpond, testing in 9 fishponds in total, feeding at 6:30 and 7 points later every day, and counting the survival rate and weight of the seedlings of the golden drum fish after the culturing is finished, wherein the survival rate is the sum of total input amount and dead fish catching per day/total input amount is 100%, and the weight is calculated by randomly extracting 100 fish seedlings.

Before the first water change and the third water change, water samples are taken in the morning to detect the oxygen content and the ammonia nitrogen content.

The oxygen content in the water body is detected according to GB/T7489-1987 iodine content determination method for water quality dissolved oxygen.

And detecting the content of ammonia nitrogen in the water body according to GB 7479-87.

Experimental results show that the industrial artificial breeding method for the golden drum fishes effectively controls the ammonia nitrogen content of the water body and accords with the GB3838-2002 surface water environment quality standard, in the embodiment, the temperature in south China of the sea of 12 months in 2020 is lower than that in the past year when the golden drum fishes meet typhoon weather in 7-10 months by feeding at different time intervals, and the survival rate and the golden drum fish weight data show that the breeding method for the golden drum fishes effectively overcomes weather factors, improves the survival rate of the golden drum fishes, and ensures that the breeding weight of the golden drum fishes reaches more than 290g after the breeding is finished.

Comparative example 1 the Huanghe jade and tourmaline are replaced by the Huanghe jade and vesuvianite, the rotting speed of the feed which is not used up by the golden drum fish in water is accelerated, the pH value is slightly fluctuated, the oxygen content and the survival rate are reduced, and the nitrogen and ammonia content is increased; comparative example 2 adjusting the pH value of the seawater to 7-8, adjusting the salinity to 13-15 per mill, obviously reducing the oxygen content in the water, increasing the nitrogen and ammonia content, and reducing the survival rate due to the change of the water quality, wherein the water quality control parameters are obtained by a large number of experiments, and the water quality is a key factor of the breeding of the Scomber formosanus; comparative example 3 the feed of the present invention is rich in various nutrients, not only can accelerate growth of the young goldfish, but also can reduce death rate of the young goldfish.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
