These fish are reared on farms are contaminated with hormones (HCG) and fed on waste foods. Add that to being transported from vietnam and you end up with a fish which doesn't have much taste and cheap. I'd stick with fresh sea or river fish myself.
Of course, you won't die from eating it but all depends if you're fussy what you put in your mouth....
Also known as Vietnamese river cobbler. It is perhaps okay baked or in a risotto but I really don't like it battered and fried. Tasteless mush rather than tasty translucent flakes.
