Technical Field
The invention relates to the technical field of aquaculture, in particular to a method for three-dimensional planting and breeding of takifugu obscurus, penaeus vannamei and water spinach.
Background
Takifugu obscurus (Takifugu obscurus), commonly known as globefish, belongs to the order Fugu, sub-order Fugu, genus Takifugu. The meat food has white and frosted muscles, is delicious, fresh, tender and tasty, is rich in protein and nutrition, and is praised as the first of the three delicacies of Yangtze river. The traditional habit of eating puffer fish is existed in China from ancient times, and the puffer fish is always regarded as a treasure on a dining table, especially in Jiang Zhe. Tetrodotoxin can be extracted from globefish liver and ovary, and has high economic value and medicinal value, and wide prospect of earning foreign exchange. At present, the annual total yield of domestic fugu obscurus reaches 2.0-5.0 ten thousand tons, and the variety with the largest culture area and the highest culture yield in the fugu obscurus is the fugu obscurus. Especially in 2016 for 9 months, the office of Ministry of agriculture and the State food and drug administration jointly release the 'processing and management of conditional releasing cultivated Takifugu rubripes and cultivated Takifugu obscurus', so that the cultivated Takifugu obscurus is protected by law for safe eating and the cultivation area of the Takifugu obscurus is increasingly enlarged. However, as the culture area is gradually enlarged, the total output is improved, the price of cultured fugu obscurus is gradually increased to the cost price, the price of the commercial fish of the fugu obscurus in the next half year of 2018 is 16-18 yuan/jin, and a plurality of farmers lose the cost.
Penaeus vannamei (Penaeus vannamei), a scientific name of Litopenaeus vannamei, is a wide-temperature and wide-salinity tropical shrimp, can grow under the conditions of 18-32 ℃ and 1-40 per mill of salinity, and is an excellent desalination culture variety. The penaeus vannamei boone has the advantages of large size, quick growth, low nutritional requirement, strong disease resistance and the like, has strong adaptability to the change of water environment factors, low requirement on the protein content of feed, high meat yield of more than 65 percent, long water leaving survival time and the like, is an excellent variety for intensive high-yield cultivation, and is a shrimp seed with the highest single yield in three cultivated penaeus vannamei boone in the world at present.
Swamp cabbage, the academic name of swamp cabbage (Ipomoea aquatica Forsk), is an annual herb, can float in water, can grow in Yangtze river basin in each province for 4-10 months, and is widely cultivated as a vegetable at present. Besides being eaten by vegetables, the feed is also a better feed.
At present, the cultivation mode of the fugu obscurus mainly comprises two modes of pond cultivation and industrial cultivation, the pond cultivation mode is abundant, the fugu obscurus is generally cultivated by adopting a single variety, the fugu obscurus is used as carnivorous fish for cultivation of the single variety, the waste of feed and the outbreak of diseases are easily caused, meanwhile, the high-density high-water-changing cultivation mode of the single variety has great influence on the water area environment, and then the water source of cultivation water is polluted in reverse, so that the yield reduction of fishery and the income reduction of fishermen are caused. Therefore, in order to solve the problem of the bottleneck of pond culture of single variety of the fugu obscurus, the culture mode and the pond culture variety structure of the fugu obscurus are urgently needed to be adjusted, the low-carbon, low-pollution and high-efficiency ecological three-dimensional culture mode of the fugu obscurus is researched and developed, the fugu obscurus is mainly cultured, the culture density and the unit yield of the fugu obscurus are reduced, benthos and aquatic plants are increased, a multi-species and multi-nutrition-level pond ecosystem is established, the feed conversion rate is improved, the total bait coefficient is reduced, the waste water discharge is reduced, the aquaculture energy efficiency is improved, the purposes of energy conservation and emission reduction, green ecology, high quality and high efficiency are realized, and the win-win purpose of ecological restoration and fishery synergy is finally realized.
Disclosure of Invention
The invention aims to provide a method for three-dimensional planting and breeding of takifugu obscurus, penaeus vannamei and water spinach.
In order to realize the aim, the invention provides a method for three-dimensional breeding of takifugu obscurus, penaeus vannamei and water spinach, which comprises 8 production steps of pond preparation, takifugu obscurus stocking, litopenaeus vannamei stocking, water spinach planting, bait feeding, daily management, growth monitoring and harvesting, and comprises the following steps:
A) preparing a pond: selecting a soil pond in Jiangzhe area with a flat bottom, wherein the depth of the pond is 2m, the water level is 1.5m, the area is 2.5-5.0 mu, and the pond is preferably rectangular, 1-2 1.5kw of oxygen-increasing machines are arranged in each pond, a 60-mesh silk mesh bag is sleeved at a water inlet for filtering, and the pond is thoroughly cleaned and disinfected before use, so that wild trash fish and shrimps are thoroughly removed;
further, in the step A, in order to thoroughly remove the harmful organisms drilled in the bottom mud of the pond, adding water to submerge the bottom of the pond for soaking before the pond is used, finely dissolving 50-80 jin/mu of bleaching powder in water, spraying the supernatant into the pond for disinfection, opening an aerator during spraying and within half an hour after spraying, then turning off the aerator, standing the pond water for 3-4 days, completely draining the disinfectant water after the pond water is clear and at the bottom, adding fresh water to submerge the bottom of the pond before the pond is used for thoroughly eliminating residual chlorine at the bottom of the pond, and draining and solarizing for later use after soaking for 2 days;
B) d, breeding Fugu obscurus: selecting and stocking the overwintering fingerlings of the takifugu obscurus in the middle ten days of 4 months, wherein when the water temperature of an outer pond rises to 15-18 ℃, the fries are easier to eat due to the fact that the takifugu obscurus fingerlings with undersized specifications are not easy to be too small, the stocking specification of the fingerlings is 80-160 g/tail, the threat to the survival of the intercropped litopenaeus vannamei is caused due to the fact that the stocking density of the takifugu obscurus is too high, the carrying capacity and the breeding capacity of organisms of the whole pond are also considered, the stocking density of the takifugu obscurus fingerlings is 800 plus one fish and 1000 tail/mu, water is fed in one week before stocking, the aerator is started for 1-2 hours every day after water feeding, the aerator is started for 2 hours in advance during stocking, and when the takifugu obscurus fingerlings are stocked, the number of each fingerling is required to be fed into the pond for thoroughly removing the mixed fishes in the fingerlings;
C) stocking the south America white prawn fries: in order to timely peel and grow the stocking shrimp larvae and reduce the killing of takifugu obscurus, the stocking time of the stocking shrimp larvae is selected in the middle and last ten days of 5 months, the water temperature of a pond is above 22 ℃, the stocking penaeus vannamei is the desalted shrimp larvae, considering that takifugu obscurus fish species can absorb the shrimp larvae, the specifications of the shrimp larvae cannot be too small, the stocking density cannot be too low, the stocking specification of the shrimp larvae is 0.8-1.0cm, the salinity of the shrimp larvae is required to be desalted below 2, and the stocking density of the shrimp larvae is 1.1-2.0 ten thousand per mu;
furthermore, in the step C, considering that the released shrimp seeds can escape from the killing of the fugu donacus and adapt to the water quality environment of the culture pond as soon as possible, the shrimp seeds put into the pond can be temporarily cultured in the net periphery of the pond for 1 week in a conditional place, a water-proof net periphery is formed on the side of the pond by using a plastic film, and the area of the net periphery is 10-20m2The water depth is 0.8-1.2m, before stocking, the salinity of water body in the net enclosure is controlledThe salt or bittern is used to increase the original salinity of the shrimp seeds out of the pond, and the stocking density in the net enclosure is 0.8-1.2 ten thousand/m2And continuously inflating the inside of the net enclosure, replacing the water in the net enclosure with pond water outside the net enclosure every day by about 30 percent, removing the plastic film net enclosure after one week, and placing the shrimp seeds with thick marks into the pond downstream.
D) Planting water spinach: after the penaeus vannamei boone is released for breeding, in order to enable the penaeus vannamei boone to avoid the residual fish of takifugu obscurus and plant water spinach in time, water spinach is planted in the middle 6 months, in order to reduce the planting cost of the water spinach and simplify the operation, the water spinach is planted by adopting a suspension rope method, the suspension rope is 75 strands, the diameter of the suspension rope is 3.0mm, when the water spinach is planted, the suspension rope is pulled to be reversely unscrewed, the water spinach is directly inserted into the suspension rope at intervals of 30cm, due to the buoyancy of the water spinach, the suspension rope floats on the water surface, the sunlight irradiation area of a pond water body is reduced due to excessive water spinach area, the stability of pond water quality and the growth of the shrimps are not facilitated, the water spinach quantity can be ensured, the water spinach quality can be effectively purified, and the planting area is controlled to be 15-30% of the breeding area;
furthermore, in the step D, considering the water flow direction when the pond aerator is started, selecting to firstly pull the suspension ropes in the rectangular pond in parallel to the transverse pond stems, tying two ends of the suspension ropes to pile heads at the water surfaces of the two longitudinal pond stems of the pond, considering the permeability of the water body of the pond, distributing the area of the water spinach into small blocks, pulling a first suspension rope at the water surface position of about 3-4m away from the transverse pond stems, then pulling a suspension rope at intervals of 3m, and pulling 3 suspension ropes while pulling one transverse pond stem, so that 6 suspension ropes are pulled in each pond generally.
E) Feeding baits: after the fugu obscurus is put into the breeding, eel powder feed with 45 percent of crude protein content is fed every day from the next day (Changxing brand, produced by everlasting Quanxing nutritional additive limited company of Jiangsu province, Xieyongde, applied to the Never sea, Zhang Haiming and Xujiabo. the growth characteristics of first-age overwintering fish species of the fugu flavidus cultivated in ponds [ J ]. Zhejiang ocean academy of academic (Nature edition), 2012,31(04): 340-; after the south America white shrimps are put into the pond for 1 month, the south America white shrimps are fed with prawn pellet feed (Minghui brand feed, produced by Zhejiang Minghui feed Co., Ltd., models 9131 and 9132), in order to enable the south America white shrimps to absorb residual feed and excrement of the takifugu orientalis after eating as much as possible, the south America white shrimps are fed with the prawn pellet feed 2 hours after feeding the takifugu orientalis with feeding time of 10:00 and 16:00 every day, and the feeding is finished after half an hour of feeding.
F) Daily management: after the fugu obscurus is put into the breeding pool, timely starting an aerator, starting the aerator for 1h at noon in sunny days in 4-6 months, starting the aerator for 8-10h at night, starting the aerator for 10-12h in nights in 7-9 months, starting the aerator for 1h at noon in sunny days in 10-12 months, starting the aerator for 10-12h at night, and increasing the starting time in bad weather; changing water for 1 time every half month, wherein the water change amount is 1/3 each time; the water spinach is cut into stubbles, the water spinach grows too fast, the water spinach of each suspension rope is intertwined, the water permeability is poor, meanwhile, the pond is covered too much, the water spinach on the suspension rope grows more than 1m in an epitaxial manner, and the stubbles are required to be cut; meanwhile, tender leaves and buds can be picked and listed;
G) and (3) growth monitoring: monitoring the growth of the takifugu obscurus for 1 time per month, randomly measuring the body length and the body weight, pulling one corner of the pond by using a pull net with the mesh specification of 3.5cm multiplied by 3.5cm in order to prevent shrimps from entering the net, and randomly sampling 30 fishes in each pond; monitoring the growth of the shrimps for 1 time every two weeks, and capturing the shrimps by combining a ground cage and a material platform, wherein 30 tails of each pond are sampled every time;
