DNA in the City

By -


Two young students using simple dna testing techniques are shining the light again on the growing problem of mislabeled seafood. Everyone in the seafood business should be outraged as consumers and I am at the deception of a few bad purveyors and retailers. Not only is it wrong to mislead the consumers, but this leads to a wider range of problems. These problems range from unfair trade to species depletion from bad catch reporting.

Read the article in the NY Times.

So I want to personally thank these two intrepid sleuths.

Here are a few ways to assure you are getting the fish you pay for (without DNA testing).

  1. Know your fishmonger.
  2. Buy whole fish, not fillet.
  3. If the price is to good to be true, it probably is.
A similar article also appears in the Canadian Globe and Mail.

Fish Yields - or - How Much Does This Really Cost Me?

I often find it necessary to explain the yield (amount of usable flesh) off of various fish. By knowing what percentage of meat will be available when a whole fish is filleted one can make an accurate analysis of; A. how much whole fish must be purchased and B. what is the true fillet cost. Knowing how to correctly perform these calculations will benefit not only seafood suppliers, restaurant chefs, but also the casual cook. Below is a list of some common fish and the net yield percentages. Actual percentages may vary depending on skill of the butcher. Salmon (head-on gutted) yields 75% skin-on fillet Snapper (head-on gutted) yields 40% skin-on fillet Mahi (headed and gutted) yields 65% skin-on fillet Monkfish (tail) yields 70% skinless fillet Cod (headed and gutted) yields 60% skin-on fillet Grouper (head-on gutted) yields 35% skinless fillet Halibut (headed and gutted) yields 66% skin-on fillet Tuna (headless bullets) yields 75% untrimmed loins Sword (headless bullets) yields 80% cen...

Flounder and Sole: or A Fish By Any Other Name Would Still Taste as Sweet.

Ever wonder what the differences are between Sole and Flounder? Some customers recently asked me the question so I thought I would take a moment to shed a bit of light on the subject. Here in North America we have no true sole only flounders. When Europeans came to the Americas they called flounders soles because they looked like the fish they knew in the "old world". This has led understandably to much confusion over the years. The only true sole would be Dover Sole, Solea solea . Lemon sole is one of the names given to winter flounder, Pseudopleuronectes americanus , (also known as black back). Usually at the retail level when multiple flounder sku's are sold; flounder is the name given to the refreshed less expensive product, and sole (or lemon sole) is the name given to the more expensive fresh cut product. Fluke, Paralichthys dentatus also called summer flounder can also be sold as sole fillet. Sometimes there is a distinction ...

Sugar Toads, What? : Blowfish Tails Check

So Friday morning I am on the phone with one of the good old boy fish sellers in Maryland, and after hearing about how the Maryland DNC might be the ones "poaching" all those rock fish (wild striped bass) in ghost driftnets he finally gives me his catch list, and he just says it 'sugar toads'. So I had to look at the calendar and make sure it wasn't April 1st, because I hate to admit it but I have no idea what this is. He says "..you know theses little puffer tails". The lights go on in my head: BLOWFISH TAILS.....send me 50 lbs to sell and a couple for testing. I have to say these are one of this Fishmonger's favorite appetizing seafood specialties, and no they are not poisonous that is a different fish. I cannot wait until these jewels arrive Monday. I did a little research and it looks like they are a 'micro-trend' according to a recent article in Grubstreet declares this, who knew. So if you get the chance try some at the next chance you...
