Clean the squid from the skin, membranes and remove the entrails. Remove crab sticks from individual packaging. Wash and dry the cilantro for serving. Prepare salad bowls.
Boil squid and shrimp. Place a saucepan of water over medium heat and bring to a boil. Salt the water, throw in the squid and cook for 2 minutes after boiling again. Then cool the shellfish and cut into thin strips. Put the pan of water back on the fire, after boiling, add the shrimp and cook for 3 minutes. Then cool them, peel them, cut them in half.
Pickle the onion. Pour salt and sugar into boiled water, pour in vinegar. Cut the onion into half rings and pour the resulting marinade over it for 15 minutes. Then drain the marinade and squeeze the onion.
Prepare the remaining ingredients. Cut the salmon into pieces, crab sticks into circles, and the whites into strips. Pass the cheese through a large-mesh grater.
