Method for improving shrimp seed transportation survival rate

Abstract

The invention discloses a method for improving the shrimp seed transportation survival rate. The method comprises the following steps of S1, shrimp seed selection, S2, shrimp seed catching, S3, shrimpseed desalination, S4, shrimp seed packaging and S5, transportation temperature control. The invention discloses relates to the technical field of aquatic product culture. According to the method forimproving the shrimp seed transportation survival rate, all-round optimization of the procedures of shrimp seed selection, catching, packaging and the like can be achieved, the shrimp seed survival rate in the transportation process is increased, and the purpose that shrimp seed can adapt to the transportation environment in advance through freshwater desalination treatment on the shrimp seed iswell achieved; according to the method, the shrimp seeds are soaked and cultured for a period of time by adopting Huolisu, so that the resistance of the shrimp seeds is improved, the survival rate ofthe shrimp seeds in the transportation process is greatly improved, long-distance transportation is realized, the situation that a large number of young prawns die in the long-distance transportationprocess is well avoided, and economic losses are prevented from being brought to shrimp seeds culture personnel.

Description

technical field [0001] The invention relates to the technical field of aquatic product cultivation, in particular to a method for improving the survival rate of shrimp fry transportation. Background technique [0002] The stocking of shrimp seedlings is generally 50,000-100,000 shrimp seedlings per mu, with a size of 1.5 cm or more. The time should be in June-July. In December, stocking precautions: Shrimp seed stocking should be carried out on cloudy or rainy days. If it is sunny, it should be carried out in the morning and evening, so as to avoid direct sunlight and affect the survival rate of stocking. Shrimp seedlings are required to be released at one time, and they can be used to raise flowering silver carp fingerlings. Each mu of shrimp ponds can be used to grow flowering silver carp fingerlings, with a specification of about 30 fish / kg. There are 200 tails per mu, and silver carp species must be stocked after 10-15 days of shrimp seedlings to ensure the demand for b...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a method for improving the survival rate of shrimp seedlings during transportation, which solves the problem that the existing shrimp seedlings have a low survival rate during transportation, cannot realize long-distance transportation, and cannot achieve The seedling selection, catching and packaging processes are all-round optimized to improve the survival rate of shrimp seedlings during transportation. It is impossible to achieve the purpose of making shrimp seedlings adapt to the transportation environment in advance by using fresh water desalination treatment for shrimp seedlings. It is impossible to soak and cultivate shrimp seedlings with vigor for a period of time to improve the resistance of shrimp seedlings, and it is impossible to avoid the occurrence of a large number of deaths of shrimp seedlings during long-distance transportation, which will bring economic losses to shrimp seedling farmers.
