SCT2002--2002
This standard revise SC/T2002-1994 "Formula feed for shrimp in China". During the revision, the preface was added in terms of format. In terms of content, the index values ​​of raw material crushing particle size, water stability (loss rate), crude protein, crude fat, and crude fiber in the physical and chemical indicators of compound feed were adjusted, the pH index was deleted, and the powder content, calcium, total phosphorus and lysine index were added. The hygiene requirements were changed to reference relevant standards. This standard was proposed by the Fisheries Bureau of the Ministry of Agriculture.
This standard is under the jurisdiction of the Marine Aquaculture Sub-Technical Committee of the National Technical Committee for Aquatic Standardization. The drafting units of this standard are: Yellow Sea Fisheries Research Institute, Chinese Academy of Fishery Sciences, National Aquatic Product Quality Inspection Center, Shandong Fisheries Technology Extension Station, and Fuzhou Haima Feed Co., Ltd.

5.4 Determination of stability in water
5.4.1 Instruments and equipment
Balance: sensitivity is 0. 01 g.
Mesh sieves (6.5 cm high, 6.5 cm in diameter, in a barrel shape) made of metal mesh with a pore size of 0.450 mm (for shrimp feed with a particle size less than 1.5 mm) and 0.850 mm (for shrimp feed with a particle size equal to and greater than 1.5 mm). Scale: accuracy 0.1 cm.
Thermometer: accuracy 0. 1 C.
Stopwatch.
Constant temperature electric oven: 105C: ±2 (.
Dryer.
5.4.2 Determination steps
Weigh three samples of compound shrimp feed, each with more than 10 grams. Take one sample (control sample) and dry it in an oven at 105C until constant weight. Perform parallel tests on the other two samples (test samples): put them in the prepared sieves respectively, and place the sieves in a container containing 5.5rm deep seawater; the seawater temperature is 25C~~28C, the salinity is 20~~30, and the seawater can also be replaced by 2.5%~2. 8% sodium chloride solution; wait for 2 h, lift the sieve from the bottom to the water surface and move it up and down three times each. When sinking, make the feed leave the bottom of the sieve, then take out the sieve. Put the feed in the sieve into a 105°C oven to dry to constant weight: take the arithmetic mean, and the relative deviation is allowed to be 4%. The stability in water is expressed by the loss rate, calculated according to formula (1). —m
