lautnusantara.com In general, fish come from either saltwater or freshwater. Both types are commonly found in traditional markets and supermarkets
Saltwater fish tend to have a stronger fishy smell compared to freshwater fish. This is because they contain higher levels of trimethylamine, a compound responsible for the characteristic fishy odor. Trimethylamine forms as a response to the high salt content in the ocean.
On the other hand, freshwater fish have a milder smell, sometimes with an earthy or muddy scent, depending on their habitat. However, the level of fishiness can vary based on the species, diet, and how they are stored after being caught.

To better understand and appreciate these protein-rich natural food sources, you should be aware of the distinctive characteristics of saltwater and freshwater fish to avoid confusion when purchasing them.
Here are five differences between freshwater fish and saltwater fish:
1. Distinct Taste
Freshwater fish tend to have a unique aroma. Their flesh is usually softer and has a lighter taste. Some freshwater fish may have an earthy or muddy scent, requiring special preparation with various spices and seasonings to eliminate any unpleasant odors.
Meanwhile, saltwater fish have firmer, chewier flesh with a more savory taste due to the higher mineral content from the ocean. They require fewer seasonings because of their naturally rich flavor. This is why fish like salmon and tuna are often eaten raw. Given these taste differences, you can choose according to your preference.

2. Bone Structure
One noticeable difference between saltwater and freshwater fish is their bone structure. Although fish bones are often avoided when eating, their structure can help distinguish between the two types.
Freshwater fish have finer, smaller bones, whereas saltwater fish—accustomed to swimming against strong currents—have larger, sturdier bones.
3. Unique Aroma
When selecting fish, it’s easy to tell the difference between freshwater and saltwater species based on their smell. Each type has a distinct aroma due to their different habitats.
Freshwater fish often have a fishy smell similar to mud, while saltwater fish have a characteristic ocean-like fishy scent. Regardless, both types should be cleaned and marinated with lemon juice or spices to reduce any unpleasant odors before consumption.
4. Nutritional Differences
As you may know, fish is a great source of healthy omega-3 fatty acids, which are beneficial for the body. Both freshwater and saltwater fish are nutritious and can be consumed regularly.
However, saltwater fish generally have higher omega-3 levels compared to freshwater fish, making them highly recommended for pregnant women and children. Nonetheless, you can still choose between the two based on your personal preference.

Price is often a major consideration for many people. In general, saltwater fish tend to be more expensive than freshwater fish. This price difference is due to factors such as higher nutritional content, the difficulty of catching them, and their breeding methods.
It’s no surprise that fish like salmon and tuna have relatively high prices compared to most freshwater fish.
