Whether you have vowed to eat more healthfully or are just contemplating the addition of seafood to your diet this year, eventually you may find yourself staring into a refrigerated seafood case, wondering which fish is not only safe and eco-friendly but also a pleasure to eat.
No need to wonder. I have a list of wholesome winners for you. The lineup includes a hearty fish that satisfies meat lovers; one for those preferring mild, “non-fishy” fish; and a versatile, no-fuss shellfish.
The perfect seafood for meat lovers
More from Zester Daily:
First on the menu is Atlantic mackerel. In the same family as tuna, the torpedo-shaped mackerel possesses firm, oily flesh and a rich, beefy taste. According to the U.S. Department of Agriculture, no fish offers more heart-healthy omega-3 fatty acids than mackerel.
Healthful, flavorful and flexible, this fish can be braised, broiled, grilled, poached, sautéed or seared as well as pickled, salted or smoked. Its bold flavor marries with acidic ingredients such as citrus, tomatoes and vinegar and balances out more mellow foods such as lentils, potatoes and mushrooms.
When shopping for Atlantic mackerel, I look for fish sourced from Canada. Caught using purse seines rather than fishing trawlers, it possesses the highest sustainability rating by the Monterey Bay Aquarium’s Seafood Watch. Other mackerel varieties, such as Spanish and King, have elevated mercury levels, making them a less favorable choice.
A ‘gateway’ fish
I think of farmed, American channel catfish as the gateway to seafood consumption. Its subtly sweet, low-fat and pliable meat puts it on the opposite end of the flavor spectrum from mackerel. It also makes catfish an excellent choice for reluctant or picky fish eaters.
With a flattened head and eight long, whisker-like barbells dotting the region around its nose and mouth, this creature bears a strong resemblance to its namesake. Typically, though, I don’t see whole catfish, with whiskers intact, in markets. Instead, what I find are skinless catfish fillets. Iridescently white to off-white in color, they often get lumped into the broad category of “white fish.”
Virtually an all-purpose fish, catfish can be baked, braised, broiled, grilled, poached, sautéed, steamed and deep-, pan- or stir-fried. It goes well with countless ingredients, including avocados, bacon, chilies, olives, tomatoes, tomatillos and wine.
Farmed channel catfish from the U.S. is among the most sustainable seafood available today. Be sure to purchase U.S.-farmed rather than imported Asian catfish, which also goes by the names “swai” or “basa.” Although equally low in mercury, imported catfish is not as eco-friendly.
A shellfish to get you started
Maybe you prefer the colorful looks, flavor and texture of shellfish but also desire seafood low in cholesterol and mercury; high in protein, vitamins and minerals; and with moderate levels of omega-3 fatty acids. I have the bivalve for you: mussels.
Inside a mussel’s hard, oblong, green or blue-black shell rests creamy, sweet, juicy meat that tastes like lobster but lacks the high cholesterol or price tag of that crustacean. Rich in protein, vitamins B-12 and C, iron and omega-3s, this shellfish packs a powerful nutritional punch.
Yet another adaptable seafood, mussels may be baked, broiled, grilled, steamed, stewed or smoked. They partner with bold, tart, spicy or mild ingredients such as beer, garlic, mustard, lemon, tomatoes, wine, chilies, curry powder, paprika, pasta, rice and zucchini. They also pair with other seafood, including clams, shrimp, squid, John Dory, snapper and monkfish. If you’ve ever tried the Provencal seafood stew bouillabaisse or Californian cioppino, then you know how nicely mussels combine with these fish and shellfish.
Although dozens of mussel species exist, I usually find farmed blue or common mussels at markets. Grown in abundance and available year-round, farmed mussels garner the coveted “best choice” label from Seafood Watch.
More good seafood choices
Along with this nourishing trio, I would suggest adding littleneck clams, farmed rainbow trout and char to your must-try seafood list. They all possess high nutritional and sustainability ratings. Couple these rankings with ease of preparation and agreeable taste, and you’ve got three more champs to add to your dinner menus.
Fans of bolder foods should also check out Pacific sardines and trap-caught sablefish. Both receive rave environmental, nutritional and cooking reviews, and both provide ample flavor and need little, if any, seasonings to shine.
No matter which type of seafood you favor, aim to make 2015 your year of healthful, sustainable and succulent fish and shellfish.
