Freshwater Fishes And Saltwater Fishes

Freshwater Fish – This type of fish have gills that do not let impurities to get inside the body of the fish. Also, it helps to keep the bodily fluids of the fish inside its body itself. They usually have a milder taste and are therefore preferred by people who do not like a strong fishy taste. Freshwater fish contain more calcium, polyunsaturated acids, and monounsaturated fatty acids. These fish have a more delicate bone structure and are therefore trickier to debone. Usually, most of the freshwater fish live in rivers and lakes, and the ideal water temperature for them is 5-15 degrees Celcius. Some examples of freshwater fish are:-  Catfish, Cisco, Mooneye, Trout, and Salmon.

Saltwater Fish- This type of fish have kidneys which very well developed and can process large amounts of water. These fish lose considerable amounts of bodily fluids due to osmosis. The lost water is then replaced by consuming more saltwater. Saltwater fish have a saltier and a more fishy taste than freshwater fish. They are as healthy as their freshwater counterparts but have a lesser amount of calcium and fats than them. They have a more massive bone structure than freshwater fish; therefore, they are easier to debone. We can typically find them in seas, oceans, and mangroves. Some examples of saltwater fish are:- Eels, Butterfish, Shark, Dolphins, and Mackerel.

Pisciculture

Pisciculture or farming is the method of raising fish in tanks or ponds for food. All over the world the most common types of them for pisciculture are

Salmon and Carp farming can be done through the caging system. In this system, we place cages in the water bodies where the fishes stay. They are fed artificially and harvested until they grow to appropriate sizes and are ready to be sold in the market. The advantage of using this method for harvesting fish is that many types of fish can be harvested together in the same water body. Also, we can then use that water body for sport fishing and other water activities. The fishes have to be kept under intense supervision because infections are prevalent when a large number of them are kept together.
