Test example 1
1.1 test subjects
Examples 1 to 3 and comparative examples 1 to 5 were cultured Babylonia and tor-brevifilis.
1.2 test methods
Before fishing, cleaning the tail algae of foxes in the breeding pond, keeping a certain water level in the pond, or slightly draining a part of water to facilitate operation, pulling the petaloid fish over the pond by using a leather strip net to close the pond, scooping the petaloid fish into a water bucket by using a basin, and carrying out water operation in the whole process;
finally draining the water in the pool, and capturing the Babylonia by using a fishing net. The caught tor brevifilis and Babylonia are weighed, and the survival rate is =
(number of survivors/total number) 100%.
1.3 test results
The multi-stage ecological polyculture test conditions of the Babylonia and the tor brevifilis are shown in table 1.
TABLE 1 Multi-stage ecological polyculture test conditions of Babylonia and Pelargonium sidoides
As can be seen from Table 1, the survival rate of Babylonia in example 3 is highest and reaches 95.2%, and compared with comparative example 1, the growth of Babylonia is limited due to the reduced planting area of the Babylonia, the food intake of Babylonia is reduced and the food source is insufficient; compared with comparative example 2, the planting area of the foxtail algae is enlarged, and although the feeding requirement of the Babylonia can be met, the algae are propagated in a large amount, so that oxygen in a pool is consumed, the water quality transparency is reduced, the water quality stability is influenced, and the survival rate of the Babylonia is reduced; compared with comparative example 3, the number of the snails is increased, the food amount and the living area are unchanged, so that the food and living environment are competing between the Babylonia, and the death phenomenon of part of the Babylonia is caused; compared with comparative example 4, the food source of Babylonia is reduced and the growth of Babylonia is affected because no food which is not completely digested by the Babylonia is caused in the water body; the survival rate of the tor brevifilis reaches 90.65% in comparative example 5, which shows that the methods of planting aquatic weeds, feeding feed, regulating water quality and the like can effectively improve the survival rate of the tor brevifilis under the condition that no Babylonia exists, and then the embodiment 3, compared with comparative example 1, shows that the tor brevifilis also provided with edible Sargassum armpit, and the growth requirement of the Sargassum armpit is met by feeding the Sargassum armpit; as compared with comparative example 3, the number of the seedlings was increased, the competition for living resources was vigorous, and the survival rate of the tor brevifilis decreased.
In conclusion, the scheme of the application can effectively utilize water space resources and improve the utilization rate of feed, does not provide additional feed for the Babylonia, saves cost and can create a suitable living environment for the parapsilosis.
The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the application.
