First, publicity and marketing, no matter how good things are, it is not easy to sell the ideal price without publicity, and an exporting country like Japan has rich experience in this regard. Many characteristics of pine crab itself make the marketing of merchants have more gimmicks, which causes the market price to rise.
Second, many crabs are rare because they can be farmed artificially, so the price is relatively reasonable. However, it is difficult to simulate the special growth environment of pine crab artificially, and practitioners have no choice but to wait patiently for the annual harvest season. The scarcity of quantity and the large number of advertisements naturally make the whole pine crab market in short supply.
Third, the cost is high. When I was a child, some people caught crabs in the stream, but catching pine-leaf crabs was not so simple. The particularity of the living area increases the difficulty of fishing, which also increases the cost invisibly, and the strict regulations of the government on fishing time also reduce the fishermen's harvest, and the output is very limited.
