Freshwater lakes are significantly different from the world's enormous, surging oceans. Who implies the organisms that inhabit them are also unique. You're probably aware that most fish are classified as lake (freshwater) or ocean (saltwater) fish. But what are the major distinctions between the two, and what does this imply for you?
We've compiled a list of the most prevalent distinctions and described them below so you can shop for seafood with confidence the next time.
When it comes to nutritional value, freshwater and saltwater fish are nearly identical; nevertheless, freshwater fish may have a little edge. Calcium and monounsaturated and polyunsaturated fatty acids are often greater in lake fish than in ocean fish. The freshwater variations of fish that survive in both fresh and saltwater possess greater vitamin A and folate.
Saltwater fish, contrary to common assumptions, do not have a much greater sodium content than freshwater fish. Fish have an internal regulating mechanism that prevents sodium from the water from being absorbed by their flesh, even if they're grown in saltwater.
Although ocean fish do not absorb sodium from the water they live in, saltwater fish have a considerably brinier, "fishier" flavour than their freshwater counterparts. Most freshwater fish, on the other hand, lack this salt flavour, making them a gentler alternative for individuals who prefer not to taste the tastes of the sea. Freshwater fish have a wide range of flavour characteristics, but their delicate, subtle flavours work well in a variety of fish dishes, from fish tacos to crockpot stews.
Differences in Mercury Concentrations
Many people are concerned about the amount of mercury in freshwater fish, particularly when it is consumed by pregnant women, nursing mothers, or small children. Because freshwater has more mercury than seawater, it's only reasonable to think that freshwater fish do as well.
That isn't the case, as it turns out. Mercury prefers to cling to rotting plant and animal materials in waters, where it may be easily broken down by sunshine. As a result, even if there is mercury in the water, it does not stay in the fish.
