This man fishing in the Causeway Bay Typhoon Shelter was an expert. Within a minute of dipping the lure into the water, he would be flicking out a 泥鯭. And he repeated it something like 10 times in the short time I was watching.
This one in his hand was about 5 inches long. You probably need 10 to 20 of these to make up one catty (一斤). Smaller ones he simply threw back into the water. He said in a good afternoon he could catch 200 of these, weighing more than 10 catties altogether.
I picked up the plastic bag into which he threw his catch. There were lots of them in there, and my guess was that they probably weighted about 3 catties altogether. He said there were larger fish to catch even in the shelter. Because the shelter opened into the harbour, bigger fish, such as foot-long mullet (烏頭) would come into the shelter. But he was fishing for 泥鯭 today, using a dough made of flour as bait.
He was fishing mainly for fun, not to sell them. He said he would eat some, and give most of them away to friends. I am not sure I want to eat them though, knowing where they came from, and what they eat.
