The term is subjective, varies by region, and many once-maligned species (like redfish) become popular as tastes or knowledge shifts, with examples including ladyfish, sturgeon, and skate wings.
 

7 Kinds of Fish You Should Never Eat

You should be cautious about eating tilapia, especially farmed varieties, due to concerns about its poor omega-6 to omega-3 ratio (promoting inflammation), potential contaminants like PCBs and dioxins from its feed, and the possible use of banned antibiotics and pesticides in some overseas farms, often linked to poor water quality and crowded conditions. While a source of protein, farmed tilapia's diet of GMOs and its overall farming practices raise health and environmental red flags compared to wild-caught fish, though wild-caught options are scarce and also carry risks, notes Global Seafoods.

Some studies also link high consumption of dark fish like salmon, mackerel, and sardines to arrhythmia, possibly from toxins like dioxins, though these are often heart-healthy choices. The key is balancing benefits (omega-3s) with risks (contaminants) by choosing low-mercury options like salmon, sardines, and trout often, and limiting high-mercury fish.

Tuna is good but should be eaten less frequently due to mercury concerns, favoring light tuna over albacore when possible.
 

Why do tuna cans say do not drain?

Tuna cans say "Do Not Drain" because the liquid inside is the fish's natural oils and juices, rich in Omega-3s, not added water or fillers; it's packed raw and cooked once to retain nutrients, so draining it would mean losing flavor and healthy fats, with instructions to mix it in instead for a moister, more nutritious product. 

Which is healthier, tuna in water or oil?

Neither tuna in water nor oil is universally healthier; tuna in water is lower in calories and fat, making it great for weight management, while tuna in oil offers richer flavor, moisture, and more Vitamin D/minerals, but you lose some omega-3s if drained. For maximum omega-3s, water-packed is often better as draining oil-packed tuna removes them, but if you need more essential fatty acids (EFAs) and don't mind extra calories, oil-packed (especially olive oil) is excellent, notes LaRuche Imports and Genova Seafood.
