Freshwater Fish & Saltwater Fish

Let’s start with fish, a definition of what it is.Then,let’s talk about how to tell if a fish is a freshwater fish or a saltwater fish. what makes a fish a fish? It lives in water. It has fins. It has gills. It is cold-blooded. To tell the difference between a freshwater fish and a saltwater is to ask the person who isn’t fishing with you, because of the fish you’re fishing for, of course, you know whether it’s a saltwater or a freshwater fish. How do I know this phenomenon?Very simple, you are fishing in the sea is salt water fish, you are fishing in rivers, small lakes, reservoirs and so on these places, that is freshwater fish.While marine waters cover more than 70 percent of the earth’s surface, freshwater covers only 1 percent. Surprisingly however, 40 percent of the 28,000 species of fish dwell in fresh waters. This is a very high proportion of species density given the small area that the bodies of freshwater actually covers.

This data indicates that there are approximately 1 species of fish for every 15 cubic kilometers of freshwater and 1 species of fish for every 100,000 cubic kilometers of marine waters.Constantly changing environments and ease of geographical separation of small bodies of water in freshwater habitat have resulted in a high degree of diversification of freshwater fish. The constantly changing environments have also forced freshwater fish to become more adaptive to their environment. In comparison, saltwater fish have been able to enjoy a relatively more stable environment in a larger ocean environment. Therefore, freshwater fish are generally more adaptable and hardier than saltwater fish.

What is the difference between Freshwater and Saltwater Fish?We can think of the following five points
• The two types live in two different environments as they are so called freshwater and saltwater.
• The number of fish species is higher in saltwater than in freshwater. However, the fish species richness in a unit freshwater volume is significantly higher than in the same volume of saltwater.
• Freshwater fishes have large and broad scales while saltwater fishes have small scales.
• Freshwater fishes have their whole bodies covered by scales while saltwater fishes sometimes cover only a portion of their body with scales.
• Freshwater fishes are adapted to conserve salt, but saltwater fishes are adapted to conserve water.
