Abstract
The invention discloses a culture method of rainbow trout. The culture method comprises the following steps of selecting a fishpond, wherein the address is selected to be at the downstream backwater bay of an artificial reservoir drain port; planting aquatic plants, wherein the aquatic plants are planted in the pond to cover more than 50 percents of the whole fishpond area; putting in rainbow trout fry, wherein germicidal treatment is performed on young rainbow trout fry; putting in feed and performing final-period management, wherein the rainbow trout feed is put in the pond, water is changed once per one to three days in summer and changed once per three to seven days in winter, the daily feeding ration is more than three percents of the total weight of fish bodies, and feeding is performed one to three times per day. According to the culture method, the rainbow trout is cultured at the down stream of the artificial reservoir drain port, a water source which is limpid, lower in water temperature and more in dissolved oxygen and mineral substance and the rainbow trout feed which has balanced nutrients are supplied to the rainbow trout, the suitable ecological environment is created for the rainbow trout, and the high-quality rainbow trout which is tender in flesh quality, rich in nutrient, low in morbidity and high in yield is provided for rainbow trout large-scaled culturing.
Description
Technical field
The invention belongs to the technical field of the cultivation such as fish, mussel, crayfish, lobster, sponge, pearl, specifically relate to a kind of rainbow trout cultural method.
Background technology
Rainbow trout happiness inhabits limpid, water temperature is lower, dissolved oxygen is more, the waters that flow is abundant, rainbow trout life limiting temperature 0-30 DEG C, suitable life temperature is 12-18 DEG C, optimum growth temperature 16-18 DEG C, during lower than 7 DEG C or higher than 20 DEG C, anorexia, decreased growth, to ingest more than 24 DEG C stopping, later weak and dead gradually, it requires high to dissolved oxygen in water, dissolved oxygen is lethal point lower than 3 mg/litre, dead lower than occurring during 4.3 mg/litre that " floating head " starts, when dissolved oxygen is lower than 5 mg/litre, respiratory rate is accelerated, rainbow trout is made to be in good growth conditions, dissolved oxygen is preferably more than 6 mg/litre, the above Fast Growth of 9 mg/litre, the suitableeest water quality is: so little 10 mg/litre of biochemical oxygen demand (BOD), ammonia nitrogen value is lower than 0.5 mg/litre, pH value 6.5 ~ 8, existing rainbow trout cultivation mainly long extensive pond culture, water quality inferiority, yield poorly, nutritive value is not high.
Summary of the invention
In view of this; the object of the present invention is to provide a kind of rainbow trout cultural method; this rainbow trout cultural method is by cultivating rainbow trout in artificial reservoir drain port downstream; for the rainbow trout feed of rainbow trout provides limpid, water temperature is lower, dissolved oxygen is more, mineral matter is more water source and nutrient balance; creating suitable ecotope to them, is the high-quality rainbow trout that rainbow trout large-scale cultivation provides large fine and tender taste, nutritious, the incidence of disease is low, output is high.
In order to achieve the above object, a kind of rainbow trout cultural method of the present invention, it comprises the following steps:
(1) fishpond is selected: addressing is at backwater gulf place, artificial reservoir drain port downstream, and water inlet, fishpond is provided with unidirectional fishing net, and barrier net is installed at discharge outlet place;
(2) planting aquatic plants: planting aquatic plants in described pond is formed area coverage and is greater than 50% of whole fishpond area;
(3) rainbow trout fry is thrown in: before input rainbow trout fry, need the sterilization processing of carrying out rainbow trout seedling;
(4) feed and final-period management is thrown in: in pond, throw in rainbow trout feed, changed water once every 1 ~ 3 day of summer, within every 3 ~ 7 days, change water once in the winter time, daily ration of feeding exceedes 3% of fish body gross weight, bait throwing in every day 1 ~ 3 time.
Further, described fishpond area 100 ~ 300 square metres, the depth of water at 1.5 ~ 2 meters, and is communicated with artificial reservoir Channel of Downstream.
Further, in step (2), described water plants is set to lotus rhizome.
Further, in step (4), described rainbow trout feed comprises fish meal 55 ~ 65 parts, dregs of beans 5 ~ 10 parts, dish cake 8 ~ 12 parts, 3 ~ 7 parts, wheat bran, the flax dregs of rice 3 ~ 7 parts, phosphatidase 1 ~ 3 part, 2 ~ 6 parts, mineral matter, multidimensional 0.5 ~ 1.5 part, methionine 0.1 ~ 0.2 part, lysine 0.4 ~ 0.6 part, yellow mealworm 8 ~ 12 parts.
Further, in step (4), described rainbow trout feed comprises fish meal 60 parts, dregs of beans 8 parts, dish cake 10 parts, 5 parts, wheat bran, the flax dregs of rice 5 parts, phosphatidase 2 part, 4 parts, mineral matter, multidimensional 1 part, methionine 0.15 part, lysine 0.5 part, yellow mealworm 10 parts.
Beneficial effect of the present invention is:
Rainbow trout cultural method of the present invention is by cultivating rainbow trout in artificial reservoir drain port downstream; for the rainbow trout feed of rainbow trout provides limpid, water temperature is lower, dissolved oxygen is more, mineral matter is more water source and nutrient balance; creating suitable ecotope to them, is the high-quality rainbow trout that rainbow trout large-scale cultivation provides large fine and tender taste, nutritious, the incidence of disease is low, output is high.
Embodiment
