求购活鲫鱼，视大小1-4$一条不等。有的请帮帮忙，拜托了

actually barramundi or nile pearch are similar fresh water fish (basa is bit freaky though).  they can be purchased from supermarket safely

it's better to consult health professionals regarding the milk issue rather than taking a risk to consume polluted food

be careful someone may bring the carps caught at torrens river or other polluted water(since it is close to city and easy to catch).  eating those contaminated fish may cause harm to human, especially pregnant ones
