Most marine fish spend the duration of their lives, from hatching to spawning and dying, in the salty waters of the sea to which they are adapted, just as most freshwater fish spend the duration of their lives in the freshwater of rivers and lakes to which they are adapted, this is mainly because they cannot tolerate major changes in salinity. Freshwater fishes are particularly vulnerable to habitat destruction because they reside in small bodies of water which are often very close to human activity and thus easily polluted by trash, chemicals, waste, and other agents which are harmful to freshwater habitats. A. These are known as catadromous fish. Even so, it is among the most beautiful freshwater fish you could get. The flow of the filtrate is faster in marine fish.

Although the exact time is unknown, in the 1950s the Ugandan Game and Fisheries Department covertly introduced the Nile perch into Lake Victoria, possibly to improve sport fishing and boost the fishery. Tuna swims constantly and are capable of bursts of extraordinary speed and are the most highly specialized fishes in regard to sustained, high levels of activity. One such example is the destruction of the endemic cichlid population in Lake Victoria via the introduction of the predatory Nile perch (Lates niloticus). Select one : A. E) Their food supplies some ions. C. They pump out ions via the gills. This surge in Nile perch numbers restructured the lake's ecology.

Their scales reduce water diffusion through the skin: freshwater fish that have lost too many scales will die. The following commercial foods are recommended as a staple diet for freshwater aquarium fish: Omega One Freshwater Flakes . Deforestation can change the structure and sedimentary composition of streams, which changes the functionality of the habitat for many fish species and can reduce species richness, evenness, and diversity. Salmon are born in freshwater and travel to seawater to live then move back to freshwater to spawn – This makes then a freshwater fish also. Another way to prevent getting this page in the future is to use Privacy Pass. However, freshwater fish is the group of ASAP species that the least is known about.

Both species are among the “100 of the World’s Worst Invasive Alien Species,” as determined by the IUCN Invasive Species Specialist Group based on their effect on anthropogenic activities, environmental biodiversity and their ability to act as a case study for important ecological issues. [5] Additionally, dams can cause the isolation of fish populations, and the lack of connectivity creates possible problems for inbreeding and low genetic diversity. The water temperature affects the amount of oxygen available as cold water contains more oxygen than warm water.[2]. The introduction of exotic fish species into ecosystems is a threat to many endemic populations. Freshwater Fish: Some species of fish tolerate and sometimes migrate back and forth between saline waters and fresh waters. The rainbow trout is invasive worldwide, and there are multiple efforts to remove them from their non-native ecosystems.
