Short answer:
Yes silver fish (small pelagic fish such as silver cyprinid/Rastrineobola argentea) are generally more nutrient-dense than tilapia, especially in micronutrients, minerals, omega-3 fatty acids, and bioavailable nutrients. Tilapia, however, is higher in protein per serving size and is widely valued for its mild taste and affordability.

Below is the detailed breakdown.

1. Protein Content

Tilapia

• High in protein: ~20–26 g per 100 g cooked

• Lean, low-fat fish

• Good for muscle growth and general nutrition

Silver Fish

• Also contains good protein: ~15–20 g per 100 g dried

• When eaten whole, contributes additional nutritional value beyond protein

Verdict:
Tilapia tends to provide slightly more protein per serving, though both are good sources.

2. Micronutrients (Vitamins & Minerals)

Silver Fish

Because silver fish are eaten whole—including bones, organs, and skin—they provide:

• Very high calcium

• High iron

• Zinc, magnesium, and phosphorus

• Vitamins A, D, B12

• Often significantly higher micronutrient density than larger filleted fish

This whole-fish consumption makes silver fish especially good for:

• Children’s growth

• Preventing anemia

• Bone health

• Pregnant and lactating women

Tilapia

• Contains B vitamins and some minerals

• Lower mineral content because only the muscle is eaten

• Low calcium since bones are not consumed

Verdict:
Silver fish is far more micronutrient-dense than tilapia.

3. Omega-3 Fatty Acids

Tilapia

• Low omega-3 levels

• Higher omega-6:omega-3 ratio

• Not ideal compared to other fish

Silver Fish

• Small pelagic fish accumulate more EPA and DHA

• Offer better omega-3 profiles beneficial for brain and heart health

Verdict:
Silver fish provides significantly more omega-3s than tilapia.

4. Bioavailability

Silver Fish

• Eating whole fish means nutrients from bones, organs, and skin are easily absorbed

• Calcium and iron are particularly bioavailable

Tilapia

• Good digestible protein

• Lower micronutrient diversity

Verdict:
Nutrient bioavailability is higher in silver fish.

5. Environmental & Economic Considerations (Bonus)

• Silver fish: usually wild-caught, small species with lower ecological impact

• Tilapia: often farmed; sustainability varies with practice
