I live in Central NJ. I want to make a spicy fish pickle. My options are (1) Tuna, (2) King Fish (3) Tilapia. Unlike Kerala, my home state in India, in the US Tuna is extremely expensive. I want to know from what is my best option to buy some good quality tuna at a reasonable price in NJ-NYC region. I would not mind the grade of Tuna, as long as it is fresh.
