The price of fish is generally between 45 yuan/500g and 48 yuan/500g, and the expensive price is more than 70 yuan per catty. According to the data, a young fish with a body length of only 15 mm can swallow the seedlings of other fish species. A fish weighing 15 kg can eat a 5 kg carp, which is equivalent to 1/3 of its body weight. Because its body is narrow and streamlined, it swims very fast. When it encounters other small fish, it will swim quickly like an arrow. When it attacks, the frightened fish has not yet understood where the enemy comes from, and it has become the food in its belly. Therefore, the fish is known as the "fish tyrant in the water". Because it specializes in preying on fish, it is beneficial and harmful to the aquaculture industry. If there are too many small fish in the water that affect the growth of large fish, it can "eliminate" these small fish, thereby purifying the fish species in the water and allowing the large fish to grow well. If there are not many small fish in the water, then the larger fish will become its prey, thereby reducing the output of fish and affecting the income of fish farmers. So some people also call the fish a harmful fish. Fortunately, most fish live in large lakes, reservoirs and rivers, and the number is not too large, so the harm caused to fish farmers is not too great. The market conditions are different, and the prices are for reference only. |
