Trout Fish
10.0best for marinade1 fillet : 1 fillet
Very close flavor and fat content; cooks in the same time as salmon

salmon substitute
for marinade.
Marinating salmon works fast because the muscle bands are short, around 1.5mm, so acid penetrates roughly 4mm in 30 minutes. Stay under 45 minutes total with citrus or vinegar marinades at pH 3.5 or lower, or the surface goes opaque ceviche-style and texture turns mealy on the grill. Oil-and-herb marinades can sit 2 hours since they coat rather than denature. Substitutes need similar muscle structure or marinade times must shift accordingly.

adjustment for marinade
Trout marinates at 1:1 with salmon's timing since the muscle structure is nearly identical, with 1.5mm bands. Stay under 45 minutes for acid-based marinades at pH 3.5 or lower; oil-and-herb mixtures can sit 2 hours. Penetration depth runs around 4mm in 30 minutes, same as salmon.
02
Halibut Fish
6.7best for marinade1 fillet : 1 fillet
Milder and leaner; reduce cook time slightly to avoid drying out
6.7
adjustment for marinade
Halibut marinates in 30 to 40 minutes for citrus or vinegar mixes at pH 3.5; the leaner 2 percent fat means the surface goes opaque faster than salmon. For longer 1-to-2-hour marinades, use oil-based herb blends at 2 tablespoons olive oil per teaspoon of herb to coat without curing.
03
Mahimahi Fish
6.7best for marinade1 fillet : 1 fillet
Firm and mildly sweet; holds up well on the grill like salmon
6.7
adjustment for marinade
Mahimahi marinates well at 30 to 60 minutes; its firm flesh resists acid breakdown longer than salmon. For grilling, use a tropical mix of 2 tablespoons lime juice, 1 tablespoon olive oil, and a teaspoon of garlic per fillet for 45 minutes; the muscle stays intact on hot grates.

Tofu
3.31 fillet : 1 fillet
Firm tofu works in plant-based versions; press and marinate to mimic salmon texture
3.3
adjustment for this dish
Firm tofu marinates 4 hours minimum since the curd absorbs slowly; press for 30 minutes first under 2 pounds of weight to expel water and create void space. Use a soy-sesame-ginger blend at 3 tablespoons soy, 1 teaspoon sesame oil, 1 teaspoon grated ginger per 4 ounces tofu.
05
Shrimp
10.01 lb : 1 lb
Cut into chunks; heartier, rich seafood flavor
10.0
adjustment for this dish
Shrimp marinates fast in 15 to 30 minutes; longer than that and acid at pH 3.5 begins to cure the protein into a ceviche-style opacity that toughens on the grill. Toss with 1 tablespoon oil and aromatics; pat dry before cooking so the surface sears rather than steams.
06
Tuna
10.01 lb : 1 lb
Rich fish, works fresh or canned
10.0
adjustment for this dish
Fresh tuna marinates 30 minutes for sear-rare prep; the dense muscle structure is denser than salmon so penetration is shallower at 2 to 3mm in 30 minutes. Canned tuna does not marinate; mix it with dressing-style coatings just before serving instead.
07
Mackerel Fish
10.01 fillet : 1 fillet
Oily and rich like salmon but stronger; great grilled or smoked
10.0
adjustment for this dish
Mackerel marinates 20 to 30 minutes max; its 16 percent fat carries flavor fast, and its pronounced flavor needs a shorter exposure or the marinade dominates rather than seasons. Use citrus-based mixes at pH 3 to 3.5 for the brightest result, then pat dry before grilling.
08
Herring Fish
10.01 fillet : 1 fillet
Oily and rich, especially pickled or smoked; best as canned or smoked salmon swap
10.0
adjustment for this dish
Herring marinates well in vinegar-and-sugar pickle brines for 24 hours at refrigeration; this is the classic Scandinavian pickled herring rather than a quick pre-cook marinade. For grilled herring, 20 to 30 minutes in oil and herbs is enough; the 18 percent fat absorbs flavor fast.
09
Cod Fish
6.71 fillet : 1 fillet
Leaner and flakier; add olive oil or butter to compensate for missing fat
6.7
10
Tilapia Fish
6.71 fillet : 1 fillet
Much milder and leaner; best in saucy or seasoned dishes, not standalone
6.7
11
Haddock Fish
6.71 fillet : 1 fillet
Mild and flaky; swap in for baked or poached salmon preparations
6.7

Sardine Fish
10.01 oz : 1 oz
Oily and flavorful; use canned for salads or pasta in place of canned salmon
