Each batch of fish should be randomly sampled with more than 1 in 100 fish, and the number of fish species should be more than 50. Repeat 4 times and take the half mean. 6.2 Full length measurement
Use a standard measuring tool to measure the straight length from the end of the object to the end of the tail fin. 2
6.3 Weighing
Suck away the water attached to the surface of the fish and then weigh it.
6.4 Deformity and injury rate
Meat service observation and counting.
6.5 Diseases
Test according to routine diagnostic methods for fish diseases

SC/T 1061--2002
Indicators|| During the inspection, if the quality index of fish species does not meet the requirements of Chapter 4 and Chapter 5, the batch of products shall be deemed unqualified. If any of them does not meet the requirements, double sampling shall be conducted for re-inspection. If they still do not meet the requirements, they shall be deemed unqualified. This batch of products is unqualified. SC/T 1061-2002
