Measured according to the method given in SC/T 1102.

6.2.3 Appearance

Observe with the naked eye under natural light.

6.2.4 Specification pass rate

The body length of the seedlings was measured according to the method given in SC/T 1102, and the proportion of seedlings with a body length >= 0.8 cm was calculated.

For example, if the number of samples is >=30 each time, and three random samples are taken, the arithmetic mean of the three results is taken.

6.2.5 Rate of abnormal body color, mortality rate, and disability rate

Live animal observation and statistics were performed, with each sample size >= 100 tails, and three random samplings were conducted. The arithmetic mean of the three results was then taken.

6.2.6 Epidemics

Same as 6.1.5.

7.1 Broodstock Shrimp

7.1.1 Batching

Wild-caught broodstock shrimp from the same source and caught at the same time are considered to be from the same inspection batch. Cultured shrimp from the same culture pond are considered to be from the same inspection batch.

Inspection and approval.

7.1.2 Sampling Method

Random samples were taken from the same batch of broodstock shrimp, with each sample consisting of 10 to 30 shrimp.

7.1.3 Judgment Rules

If the disease test fails, the batch of broodstock shrimp is deemed unqualified and should not be retested; if other tests fail, samples should be taken again for retesting.

The results of the re-inspection shall prevail.

7.2 Seedlings

7.2.1 Batching

Each seedling pond is considered an inspection batch, and each batch is inspected before sale.

7.2.2 Sampling Method

Three random samples were taken from different locations within the seedling bed and combined together as a reserve sample. The number of reserve samples should not be less than the number of samples taken.

100 times.

7.2.3 Judgment Rules

If the disease test fails, the batch of seedlings is deemed unqualified and should not be retested; if other tests fail, samples should be taken again for retesting.

The results of the re-inspection shall prevail.

9.1 Broodstock Shrimp

9.1.1 Animals should be caught and transported immediately to minimize the temporary holding time before transportation. During transportation, they should be protected from sun and rain.

9.1.2 The transport water should ideally be 14°C~18°C, salinity 25~30, and dissolved oxygen >5mg/L.

9.1.3 Plastic bags, canvas buckets, live water boats, and live shrimp transport vehicles can be used for transportation.

a) Transport using oxygenated plastic bags. Add 10L of seawater to the bag, place 3-5 broodstock shrimp inside, fill with oxygen to 15L-20L, and tie the bag tightly.

b) Transport using canvas buckets, live water boats, and live shrimp transport vehicles. During transport, maintain aeration or change the water midway to ensure adequate dissolved oxygen levels in the water.

5 mg/L. The transport density of broodstock shrimp should be determined based on factors such as weather, transport time, and water body size. The transport density should be calculated per cubic meter of water.

50 to 80 fish is ideal, and the transportation time should be controlled within 18 hours.

9.2 Seedlings

9.2.1 Transport can be carried out using canvas buckets, plastic buckets, or plastic bags filled with oxygen. When the water temperature is 16°C~17°C, use a box truck to carry inflated plastic buckets for transport.

Each cubic meter of water can transport 800,000 to 1,200,000 shrimp larvae, each approximately 0.8cm to 1.2cm in length; transported using oxygenated plastic bags, each bag contains...

One-quarter water volume can transport 1400 to 1800 shrimp larvae with a body length of 0.8cm to 1.2cm per liter of water, and the transportation time should be controlled within 18 hours.

9.2.2 The temperature difference between the water used for transportation and the water used for seedling cultivation should be less than 3°C, and the salinity difference should be less than 5.

9.2.3 Transportation should be carried out in the early morning or late evening to avoid exposure to sunlight or rain.
