The answer to this question was provided by Nikolai Platoshkin, a renowned diplomat, political scientist, and leader of the "For New Socialism" movement. I recorded his commentary at the end of August, but decided to post it after I went to the store to buy fish again. Many of our compatriots will probably be interested to know that Russia currently catches around 4 million tons of fish, while in the USSR, this figure reached 12 million. It seems like there's nothing complicated about production; you just need to catch it, freeze it, and bring it to the store. Nikolai Platoshkin provided more details about the situation.
