As crab season has arrived in Taiwan, Lai Hui-lien, a physician at the Ministry of Health and Welfare’s Keelung Hospital, is urging members of the public to show restraint. Crab meat is very rich in protein, which means it is not healthy to eat too much of it, Lai said, especially people who suffer from hypertension or cardiovascular diseases. People with gout or skin allergies should avoid crab completely, she said. Deemed to be “cold” in terms of Chinese medicine, crabs should not be eaten alongside with beer and pears, Lai said. Crab season coincides with persimmon season, but the two do not go together, as the protein in crab meat can coagulate with the tannin in persimmon and lead to indigestion, which can cause food in the intestines to ferment and lead to stomach pains and diarrhea, the doctor said.

It is not just consumers who look forward to crab season every year, the nation’s fishermen do too. Fishermen say that Taiwanese crabs fall into two categories: those born in captivity — mainly Chinese Mitten crabs — and wild crabs such as the stone crabs found off New Taipei City’s Wanli District. Wanli is one of the top four ports nationwide for crab cuisine — a distinction it shares with the city’s Yehliu and Gueihung districts and Dongao in Yilan County. However, the popularity of crabs in Wanli has led to a significant hike in prices. Local business operator Lu Feng-e said crabs and crab dishes in Wanli are now a lot more expensive than they are in Keelung, about a half-hour drive away. His advice to customers it to try to select fresh crabs by observing their “liveliness.”
Chiang Ching-shu owns the Chingshan Chinese Mitten Crab farm in New Taipei City’s Shihmen District and he said the quality of crabs bred at his farm are the result of a lot of work and top quality feed. There are seven ponds on his farm, spread across 3,000 ping (9,917.37m2) of land and filled with mountain water from Yangmingshan, he said. His crabs are fed mackerel, corn, wheat and silver-stripe round herring for 10 months, but no antibacterial medicines or growth hormones are used. The farm sends a sample of its crabs to the SGS Co and the New Taipei City Department of Agriculture for inspection before sales commence each year, Chiang said. The meat from male Chinese mitten crabs is more tender, while the females allow gourmands to enjoy both the meat and eggs, Chiang said. If consumers want to pick up the freshest crabs, they should look for bubbles in the water, and buy from local vendors, he said. The going prices are: for six crabs totaling 1kg, NT$2,000; five crabs totaling 1kg, NT2,400 and four crabs totaling 1kg,NT$2,800, Chiang said.
