Americans will consume more than 3 billion pounds of fish this year, but some of us know so little of piscine matters that we buy our seafood at the supermarket, where "catch of the day" should more accurately be referred to as "catch of the week." At Delray Seafood, the creatures are delivered to the back door daily, and fishmongers clean them so quickly that, to paraphrase Satchel Paige, they can put a knife to a snapper as you turn out the light and there'll be two clean filets on the table before the bulb goes off. Freshness is the whole game when it comes to seafood, but variety is still the spice of life, and Delray hauls in lesser-known species such as Spanish mackerel, butterfish, sea trout, and mullet -- all shining atop glittery crushed ice. Prices generally range from $4.95 a pound (flounder) to $13.95 a pound (Chilean sea bass), which is slightly higher than the supermarket, but the difference in quality is quantifiable. Delray Seafood has taken pride in its products since 1960, when Nicholas and Nellie Griek opened the shop. Their son and his family run things now and are knowledgeable enough ichthyophiles that they can help you choose wisely for dinner and perhaps also tell you what piscine and ichthyophile mean. Closed Sundays and Mondays.
