Vivid
Splendid, Brilliant
な adjective
Alright, so it's not quite the same, but something that is fresh is also vivid and splendid. I know those are a couple things I'd associate with freshness. Try to make the connection here before moving on.
Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You didn't learn that reading with this kanji, so here's a mnemonic to help you: This vivid and splendid fresh fish is MINE! You grab the other (あざ) one that's not as vivid and splendid. This one is mine.
