Description
Technical Field
The invention relates to the technical field of cultivation of cheilinus comilina, in particular to a relay type cultivation method for high-level pond cultivation and modularized circulating water cultivation of a cheilinus comilina deepwater pond.
Background
The cheilis belongs to the order of carp, the family of carp, the subfamily of cheiliaceae, commonly called as rock spots, and the cheilis is loved to inhabit in a stream with a gravel bottom, fresh water quality and turbulent water flow, and the small economic fish is mainly distributed in various provinces in the south of Yangtze river. The cheilis is a very good variety, has tender meat, delicious taste and rich nutrition, is deeply favored by consumers for a long time, gradually becomes a cool fishing object for fishermen, causes the gradual exhaustion of wild resources in the brook, and further aggravates the imbalance of supply and demand relations due to slow steps of artificial propagation culture technology research.
The current main flow cultivation mode of the cheilinus capitatus is a barrel canvas pool running water cultivation mode, the cultivation period generally needs 1.5-2 years, the period is long, the cultivation condition is uncontrollable, the cultivation success rate is low, and the problems of high construction cost, high operation cost and high labor force technical requirements exist in the emerging industrial circulating water cultivation.
Disclosure of Invention
The present invention aims to solve or at least alleviate the above-mentioned problems of the prior art.
In order to achieve the above purpose, the present invention provides the following technical solutions: a relay type cultivation method for deep water pond high-level pond cultivation and modularized circulating water cultivation of a cheilinus lucidus, comprising the following steps:
s1: clearing and sterilizing the pond: selecting a deepwater pond with sufficient ventilation and sunny power, cleaning the deepwater pond, and then adding 150-250 kg/mu of quicklime into the whole pond for splashing so as to achieve the aim of removing toxic and harmful substances;
s2: erecting a net cage: erecting a net cage with the depth larger than 3m in a deep pond, wherein the mesh size, the net cage depth and the like take the principles that fish cannot escape, materials are saved, water exchange is facilitated and the like;
s3, pond fertilizer water: one week before fish fry rearing, amino acid water-fertilizer paste and other products are used for water fertilizer, and when a large amount of rotifers and branch angles can be seen in water, the fish fry can be prepared for rearing;
s4: and (3) fish fry stocking: selecting a smooth lip fish with an average body length of 0.6 cm-0.8 cm, strong physique, no obvious focus and strong swimming power, soaking the fish with 2% -4% saline water for 1-3 minutes after the fish is soaked for disinfecting the fish, and then stocking the fish in a deep water pond;
s5: daily management: the bait is not needed to be fed because the pond is provided with enough live baits for the fries to eat 1 week before the fries leave the pond. When the water quality is changed to be thin, a proper amount of powdery feed can be fed, so that the fish fry can eat the feed on one hand, and the feed is used for fattening the water on the other hand. When the amount of live baits in the water body is observed to be small, feeding is started 3 times per day, and the feeding is respectively 8 in the morning: 00-8: 30. 10 am: 30-11:00 and 16 pm: 30-17:00, feeding powdery materials or crushed materials with the feed position being relatively fixed and the feed amount being less than 0.5mm, wherein the protein content is required to be 40-45%, feeding according to the weight percentage of the fish, the daily feeding rate is 3-5%, and monitoring the water temperature of the water body in real time;
s6: transplanting: after the water temperature is lower than 20 ℃, moving the fish in the net cage into a modularized culture pond for culture, wherein the feeding amount is 3% -4% of the total weight of the fish, and feeding for 2-3 times a day, namely 9:00-10:00, 15:30-16:30 respectively;
s7: and (3) periodically changing water: after the cultivation wastewater in the modularized cultivation pond is discharged periodically and subjected to links such as filtration, microbial degradation and ultraviolet disinfection, the clean water is conveyed back into the fish pond again, and the water can be repeatedly used.
