Resumo: 	Once fished, the shrimps must be cooled quickly in water cooled in order to slow down all chemical and bacteriological activities. In addition, in order to avoid blackening (mélanose) shrimps (céphalothorax and legs) it is necessary to treat those with an antioxydant product. The product currently used to inhibit this enzymatic change is the soda niétabisuifite (Na-&gt; S7 O5), until now, after being fished. the shrimps were directly soaked in a cooled water tank, containing the pesticide.  The solution of treatment was progressively prepared needs. The concentration of this one was approximately 2 to 3% of métabisulfite, that is to say 6 to 9 G of SO2 per liter for a starting product containing 320 G of SO2 approximately.  In order to preserve a good quality of the liquid of treatment it was essential to often renew it (every 400 to 500 kg) what was not always the case, the métabisulfite being often added progressively with the liking of the appointed person with the treatment of shrimps.  In order to cure this delicate problem of renewal of vat and uniformity of the treatment, the SODACAL obtained the system of treatment by sprinkling.
