Problems solved by technology

Penaeus japonicus has the habit of submerging sand. If it is cultured without submerging sand, its survival rate will be significantly reduced. Therefore, the culture of Penaeus japonicus all needs to be covered with a 15-20cm thick sand layer in the culture pond. The high density of breeding will lead to a large amount of feeding, which will lead to more residual bait and more shrimp feces. In addition, the death of algae and the precipitation of suspended solids in the breeding pond will eventually cause the sand layer to be quickly accumulated by dirt. , In a culture environment with weak light, these dirt will quickly rot and smell, further blackening the sand layer, making it impossible for Penaeus japonicus to inhabit, and at the same time inducing the occurrence of shrimp diseases, making the growth rate of Penaeus japonicus slow down, and the culture Phenomenon of decreased survival rate

Embodiment 1

[0039] Effect of embodiment 1 different photoperiods on the growth of Penaeus japonicus

[0040] The body length of Penaeus japonicus used in the selection experiment was (1.930±0.217) cm, and the initial weight was (0.064±0.020) g. Four different light groups were set up in the experiment: total darkness (D), full light (L), light:dark=10L:14D and light:dark=14L:10D, and all treatment groups were set in 3 parallels. During the experiment period, fresh Artemia japonicum was fed to the prawns. The daily feeding amount was 10-15% of the body weight of the prawns. The feeding was carried out at 8:00 and 17:00 every day, and the ratio of feeding in the morning: evening 3:7, and then weigh the weight of Penaeus japonicus after 2 months of breeding, and calculate the specific weight gain rate and survival rate.

[0041] The experimental results are shown in Table 1. With the prolongation of the light time, the survival rate (S), specific growth rate (SGR) and molting rate (MF) of Pen...

Embodiment 2

[0045] Effect of different drugs on the growth of Penaeus japonicus in embodiment 2 bait

[0046] 1. Effects of different drugs on the growth of Penaeus japonicus

[0047] The body length of Penaeus japonicus used in the selection experiment was (2.48±0.28) cm, and the initial weight was (0.23±0.08) g. The experiment set up 4 different drug feeding groups (fluoxetine, paroxetine, sertraline and fluvoxamine are neuroleptic drugs) and a control group, in which the control group was sanded, and the drug feeding group was not sanded. ; The dosage of the drug feeding group was 15 mg / kg, and all treatment groups were set in 3 parallel. In this experiment, the drug and bait were mixed evenly to make granules, and then fed with a layer of film on the surface of the granules. This treatment method can effectively prevent the loss of drugs in the bait. During the experiment, the daily feeding amount was 5% of the body weight of the prawns, which were fed at 8:00 and 22:00 every day, a...

Embodiment 3

[0058] Embodiment 3 uses fluoxetine to the cultivation of Japanese prawns

[0059] The method of using fluoxetine to cultivate Penaeus japonicus adopted in this example, its specific implementation process is as follows:

[0060] 1. Workshop treatment: Spread multi-layer black plastic cloth or sunshade nets on the roof and workshop windows to prevent light from entering the workshop. Use an illuminance meter to measure that the light in the workshop during the day does not exceed 20lx; install lighting devices in the workshop to prepare During the breeding period, it is used to feed shrimp seedlings, and pay attention to opening windows for ventilation at night.

[0061] 2. Breeding pool preparation: the breeding pool is of brick and cement structure, with a circular bottom surface and an area of ​​25m 2 , the depth of the pool is 1.2m, and the bottom of the pool is in the shape of a pot bottom. Use 40ppm chlorine dioxide to sterilize the breeding pool before use.

Abstract

The invention provides a method for breeding marsupenaeus japonicas by fluoxetine. The method includes workshop treatment, preparation of a culture pond, spreading of young marsupenaeus japonica, dividing, feeding, water changing and capture. The method has the advantages that according to living habits of the marsupenaeus japonicas, a certain amount of the fluoxetine is added into baits to inhibit the habit of submerging in sand, so that sand is not laid during breeding of the marsupenaeus japonicas, manpower and material resources wasted in sand laying can be saved, and shrimp diseases induced by sand laying can be reduced; through scientific and reasonable spreading density, bait feeding amount and daily management, growth of the marsupenaeus japonicas is accelerated, and the survival rate and weight gain rate in cultivation are increased; the success rate of industrialized breeding of the marsupenaeus japonicas can be ensured, a novel breeding mode under artificial conditions is provided, and the method is beneficial to large-scale breeding and promotion and has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of prawn cultivation, in particular to a method for cultivating prawns by using fluoxetine. Background technique [0002] Japanese prawns (Marsupenaeus japonicas) belong to the order Decapod, Shrimpidae, and the genus Penaeus spp. There are also distributions along the coast. Penaeus japonicus has the characteristics of rapid growth, strong disease resistance, long survival time in dry dew, and high survival rate in long-distance transportation. Because of its high economic value and high market price, it is an important economic product in coastal areas of my country. types of prawns. [0003] In recent years, due to the increasing demand for Penaeus japonicus in the market, pond culture can no longer meet the increase in daily demand. Therefore, the industrial culture of Penaeus japonicus has gradually emerged and achieved good economic benefits. Penaeus japonicus has the habit of submerging sand. If it ...
