Feeding five times from 7 o' clock every day, every time interval is 2h, after feeding five days, observing the food intake of the saury larval fish, gradually increasing the proportion of fly maggot powder, and preparing for subsequent domestication and transferring of iced fresh fly maggots.
6. Domestication and feeding of fly maggots
After the hairtail larva fishes grow to 5cm, transferring the hairtail larva fishes from the cement pond into an earth pond for cultivation, placing 1 million hairtail larva fishes in each mu according to the area of 3 mu of pond mouth, the water depth of 1.5m and the water depth of 1 mu, and transferring to a 9 hairtail larva fish flow type feeding device in the picture 2 to cultivate the hairtail larva fishes when the hairtail larva fishes are cultivated to the specification of 7-8cm, and feeding the hairtail larva fishes 7:00 in the morning and 14:00 in the afternoon one time each day.
Firstly, 0.5h before feeding, opening a second discharge valve 10 (discharge pipeline valve), then opening a pump body 12 (submersible pump, 300W) which is about 5m away from a feeding area 11 to suck the middle and upper layer water in a culture pond 21 (hairtail pond) to reach the top end through the bottom of an inverted cone-shaped storage bin 13 of 80cm, and falling into the feeding area 11 which is 4m long and 2m wide and is made of a PVC floating pipe from a high position 20cm away from the water surface along a discharge pipeline 15 through a discharge gate, so that on one hand, the dissolved oxygen in the feeding area 11 is increased, and on the other hand, the fish swarm is attracted by water flow sound to respond and gather to form conditioned reflex.
Secondly, after the fish school is gradually gathered, the frozen fly maggot powder and the fairy shrimp are gradually added into a storage bin 13 to be gradually thawed and dissolved and fall into a feeding area 11 along with the water flow through four evenly distributed shunt pipes 14, then a second bait 16 (frozen 1-instar fly maggot larvae) is placed into the storage bin 13 to be gradually thawed and dissolved and fall into the feeding area 11 along with the water flow through four evenly distributed shunt pipes 14, and in the later period, the palatability of the bait is gradually improved along with the growth of the larval fish of the saury, and the second bait 16 (frozen 1-instar fly maggot larvae) is gradually changed into 2-instar fly maggot larvae and 3-instar fly maggot larvae.
Finally, after the feeding is finished, a self-priming pump 17 (the prior self-priming pump is preferred, 2kW) is started, residual bait and excrement which is located under the feeding area 11 and is attached to a sewage collection box 18 (a funnel type sewage collection device, stainless steel materials and 0.5m long 4m wide 2m) arranged at the bottom of a culture pond 21 is physically filtered through a filter screen 20 (the filter screen is preferably coiled through a 120-mesh sieve) arranged at a water outlet of the self-priming pump 17 by a recovery pipeline 19 communicated with the bottom and used for recovering sewage, the filtered pond water flows back to the culture pond 21, the continuous sewage suction is carried out for 0.1-0.2h every time, and the collected residual bait and excrement is concentrated and dried in the sun and then used as supplement of fly maggot culture bait, so that the residual bait is recycled.
The invention provides an artificial breeding system which comprises a drip-type feeding device and a running water type feeding device, wherein the drip-type feeding device is used for feeding first bait 6, the running water type feeding device is used for feeding second bait 16, and a bait feeding method for artificial breeding of the hairtail is provided based on the artificial breeding system, and the first bait 6 is dripped out by the drip-type feeding device from the hairtail with the length of 2-4cm for feeding the hairtail; when the saury grows to the specification of 7-8cm, feeding second bait 16 by using the running water type feeding device for feeding the saury; therefore, by feeding the fly maggot powder and the fly maggots according to a specific mode at different growth stages of the hairtail, the hairtail has better palatability and higher nutritional value, can promote the large-scale culture of the hairtail, and solves the problem that the existing artificial culture equipment for the hairtail cannot effectively carry out the large-scale culture of the hairtail.
It should be noted that, in recent years, the feed industry in China develops year by year, protein sources are sought from multiple aspects, and the common housefly larvae, fly maggots, which have comprehensive nutrition and crude protein content of 58.80% -63.89%, are gradually concerned. A plurality of researches show that the content of the crude protein of the fly maggot protein is close to that of the imported fish meal, and the fly maggot protein simultaneously contains a plurality of fatty acids, amino acids, vitamins and mineral substances, and has the nutrition and health care effects of promoting the growth and development of animals and resisting tissue hypoxia. Meanwhile, antiviral active substances exist in the fly maggot protein, and the addition of the fly maggot protein in the feed can improve the organism immunity of aquatic animals, reduce the use of antibiotics and ensure the product safety of the aquatic animals and the health of human beings. Meanwhile, the housefly has wide sources, low requirement on culture technology, less occupied area and capability of mass production. Therefore, the self-breeding of the fly maggots can feed the fly maggot powder and the iced fresh fly maggots in different growth stages of the hairtail according to a specific mode, has better palatability and higher nutritional value, and can promote the large-scale breeding of the hairtail.
