I'd like to know about the types of crab available at most wet markets in HK. I've seen the green ones, brown ones and brown ones with little dark marks on them. As far as I know the green ones are mud crabs but I'm not 100% sure on that. Unfortunately none of the shopkeepers are able tell me in english what types of crabs they are either.
I usually buy the green ones, I just steam them and have them with rice or butter and bread buns. I don't buy them that frequently which is why i never thought to ask about them before. I'm just looking to get any info on them from anyone that knows.
As far as pricing does 88 per catty sound about right. Most of the shopkeepers won't let me haggle for price so I'd like to know if I am paying too much at the local wet market. Also, is it normal for them to tie up the crabs with about 4ft of soaking wet straw? I weighed the straw rope from two crabs i bought earlier and they were 22 and 25 grams. That means for every four crabs that's around 80-100grams included int he weight just from the string added to the price.
