Description
Technical Field
The invention relates to a method for breeding salt pan shrimps, in particular to a method for ecologically breeding the salt pan shrimps in a saline-alkali land pond by taking artemia as main natural bait.
Background
Artemia (Eubranchipus vernalis), also known as artemia, is a small crustacean which is distributed worldwide and resistant to high salt, and has become a high-quality biological bait for aquaculture due to the advantages of high astaxanthin content, high protein content, unsaturated fatty acid content higher than saturated fatty acid content, complete biological nutrition and the like. China is one of the countries in the world that produces Toyota insects, wherein the Bohai Bay salt pan-cultivated Toyota insects have high quality, and the mode of artificial stocking in the salt pan is mainly used.
The salt pan shrimp is also called brine shrimp, is a special product of Bohai Bay, is cultured by fully utilizing the characteristic of wide salt adaptability of the south American white prawn, is cultured in a saline-alkali land pond with the salinity of 35 per mill to 60 per mill, and ensures the natural safety of the salt pan shrimp by the unique environment. The salt pan shrimp culture mainly adopts a rough culture mode, the salt pan shrimps and the artemia coexist in the culture water area, the artemia become the main food source of the salt pan shrimps, and other auxiliary biological baits are rotifers, brine maggots, salt algae and the like, so that the wild pure natural characteristics of the salt pan shrimps are ensured. The salt pan shrimp has the following advantages: firstly, because the salinity in the culture water area is higher, other aquatic organisms are difficult to survive, and no enemies such as fishes threatening the survival of shrimps in the salt pan exist; the breeding water area is suitable for breeding the brine shrimp, and the brine shrimp with excellent quality can provide quality guarantee for the breeding of the brine shrimp; and thirdly, because of high survival salinity of the salt pan shrimps, although the growth of the shrimps is relatively slow and the yield is low, the salt pan shrimps cultured by the salt pan shrimps are long in nutrient accumulation period due to natural growth, the meat quality of the cultured salt pan shrimps is tight and tender, the taste of the salt pan shrimps is sweet, and the content of nutrient substances such as protein, astaxanthin, amino acid, EPA, DHA and the like beneficial to the health of a human body is far higher than that of the penaeus vannamei grown in other environments.
At present, the utilization mode of the saline-alkali soil is mainly to dig a pool for fish culture after transformation, the saline-alkali soil is transformed by a comprehensive fish culture technology, after fish culture for a plurality of years, the land can be transformed into the farmland as required after being completely or basically desalinated, but the mode has complex procedures and slow effect, simultaneously changes the resource characteristics and is not beneficial to the diversified development of the ecological environment. Therefore, after standardized transformation of the pond, the saline-alkali land pond resources in an idle state develop ecological breeding of the shrimps in the saline-alkali land pond with the artemia as main natural baits, and the method is an effective way for utilizing the saline-alkali land at present.
