Embodiment 1

[0024] S1. Selection of shrimp seedlings: first select seedlings with bright color, strong body, uniform size and thickness, strong vitality and good physique, and remove shrimp seedlings with poor physical fitness, broken limbs or residual limbs. The metamorphosis rate of pond larvae reaches 90%;

[0025] S2. Shrimp seedlings start to catch: stop eating 2 days before the shrimp seedlings start to catch, and put 7g of vitality feeding agent into the whole breeding pond for soaking to improve the anti-stress ability and survival rate of the shrimp seedlings. After soaking, start to catch. The water temperature is stable at 15°C when the shrimp seedlings are caught, and the shrimp seedlings are caught lightly, so as to avoid injury to the shrimp seedlings caused by excessive operation. If the temperature is too low, it is not easy to catch shrimps quickly, so as to prevent injuries caused by rapid operation. The parts by weight include: 4 parts of bifidobacterium, 4 parts of lac...

Embodiment 2

[0030] S1. Selection of shrimp seedlings: first select seedlings with bright color, strong body, uniform size and thickness, strong vitality and good physique, and remove shrimp seedlings with poor physical fitness, broken limbs or residual limbs. The metamorphosis rate of pond larvae reaches 85%;

[0031] S2. Start catching of shrimp seedlings: Stop eating 1 day before the catching of shrimp seedlings, and put 5g of vitality feeding agent into the whole rearing pond for soaking, so as to improve the anti-stress ability and survival rate of shrimp seedlings, start catching after soaking, The water temperature is stable at 10°C when the shrimp seedlings are caught, and the shrimp seedlings are caught lightly, so as to avoid injury to the shrimp seedlings caused by excessive operation. If the temperature is too low, it is not easy to catch shrimps quickly, so as to prevent injuries caused by too rapid operation. The parts by weight include: 3 parts of bifidobacterium, 3 parts of...

Embodiment 3

[0036] S1. Selection of shrimp seedlings: first select seedlings with bright color, strong body, uniform size and thickness, strong vitality and good physique, and remove shrimp seedlings with poor physical fitness, broken limbs or residual limbs. The metamorphosis rate of pond larvae reaches 88%;

[0037] S2. Start catching of shrimp seedlings: Stop eating 3 days before catching shrimp larvae, and put 10g of vitality feeding agent into the whole rearing pond for soaking to improve the anti-stress ability and survival rate of shrimp larvae. Start catching after soaking. The water temperature is stable at 20°C when the shrimp seedlings are caught, and the shrimp seedlings are caught lightly, so as to avoid injury to the shrimp seedlings caused by excessive operation. If the temperature is too low, it is not easy to catch shrimps quickly, so as to prevent injuries caused by too rapid operation. The parts by weight include: 5 parts of bifidobacterium, 5 parts of lactobacillus, 50...

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...
