Sea Fish and Freshwater Fish Are Different, Here’s What to Consider Before Buying

Fish is one of the best sources of protein for the family. It can be fried, grilled, cooked in soup, or made into pepes—everything tastes good as long as the fish is fresh.

However, before buying, it’s a good idea to understand the difference between sea fish and freshwater fish. Although both are fish, their characteristics are quite different and can affect the taste and cooking results.

1. The Texture of the Flesh Is Different

Sea fish live in waters with stronger currents. Because they constantly move against the current, their muscles are more developed. That is why sea fish generally have firmer and more elastic flesh.

On the other hand, freshwater fish live in ponds, rivers, or lakes where the water is relatively calm. Their flesh tends to be softer and not as firm as sea fish.

If you want fried fish that holds its shape well and does not fall apart easily, sea fish is often a suitable choice.

2. The Taste and Aroma Are Not the Same

Fresh sea fish often has a slightly natural sweetness. Its aroma is distinctly from the sea but not overly strong if the fish is truly fresh.

Meanwhile, freshwater fish usually has a stronger fishy smell and can sometimes carry an earthy or muddy scent. For this reason, proper cleaning and soaking are important before cooking to help reduce the odor.

3. The Size and Variety Are Very Diverse

Both sea fish and freshwater fish come in a wide range of sizes, from small to large.

Sea fish are known for having many large varieties, such as tuna and snapper. However, freshwater fish also offer plenty of options, such as tilapia, gourami, and catfish, which are often family favorites.

Simply choose according to your cooking needs and your family’s preferences.

4. The Bone and Spine Structure

This is especially important when cooking for children.

Sea fish generally have a large central bone and stronger bone structures. This is influenced by their environment with stronger ocean currents.

Freshwater fish typically have smaller bones. However, some types contain many fine bones, so extra care is needed when cleaning and serving them.

So, Which One Should You Choose?

There is no superior option; it all comes down to preference and family needs.

What matters most is not only the type of fish but also its freshness. Make sure the eyes are clear, the gills are bright red, the flesh is firm, and there is no strong unpleasant odor.

In the end, fresh fish will always make any dish taste better at the family table.
