Most of the salmon produced in the Atlantic Ocean (99%) is farmed, while the salmon produced in the Pacific Ocean is caught in the wild (over 80%).
There are many ways to eat salmon. Japanese people will cut salmon meat into sashimi or sushi, and also make salmon head into salted fish and other dishes. Europeans and the United States will make smoked salmon by hot or cold smoking, or can salmon for storage. Because raw salmon meat contains anisakis or marine parasites, salmon will not be eaten as raw fish before refrigeration is invented. Herring is an important economic fish; Its fish density and individual number are unparalleled. It can be said to be the largest fish in the world. Why can herring breed so much? The reason is that herring is good at adjusting the light, so that fish can smoothly enter various depths of water to catch food.
The dense swimming of herring is a very spectacular sight. Two or three days before the herring began to migrate, several large individuals with bright colors opened the way as pioneers, followed by dense schools of fish on the shore. Fishermen can accurately judge the arrival of large groups of fish according to the color of water on the shore, the movement of seawater, the special splash of fish fleeing and the hovering and singing of large groups of seabirds in the sky. At this time, we should immediately go fishing in the net.
The dense herring swim in the water depth of about 8 meters near the coast for 1- 12 days, and then enter the shallow water with algae to breed. The females lay eggs and the males ovulate. Herring eggs are sticky eggs, fertilized eggs stick to seaweed, and a new life begins. Because the water depth of herring spawning ground is only about l meters, because the fish are too dense, the head and back of the fish above will be exposed to the water. A large amount of semen discharged by the male fish makes the sea water white and gelatinous. Saury is a pelagic fish, inhabiting the subtropical and temperate waters of the Pacific Ocean along the coast of Asia and America19-58 N, mainly distributed in the temperate waters of the North Pacific Ocean. It is a cold-water fish, and the suitable temperature ranges for shrimp and poda are 10-24℃, 15- 18℃. The optimum temperature for feeding is 15-2 1℃.
From August to 65438+February, saury on the Pacific side of Japan swam south from Hokkaido to northeast to reach the southern waters of Japan, and from February to July, it swam north to saury near Hokkaido to Thousand Islands.
The body is rich in protein and fat, so it tastes delicious, and can be steamed, boiled, fried and roasted at a low price (the price in the Japanese origin market is between 70 and 90 yen per kilogram). According to the analysis of nutritional components of saury by Shanghai Fisheries University, the protein content of saury is 20.7%.
