Why are fish from the Mekong River located in Asia so important?
“Migrating fish are an extremely important component of the ecosystem services that the Mekong River and its tributaries provide each year,” he added. “The fishery alone in the Mekong River basin has an estimated value of over 10 billion dollars.”
Which fish migrate from river to sea?
Anadromous fish migrate from the sea up (Greek: ἀνά aná, “up” and δρόμος drómos, “course”) into fresh water to spawn, such as salmon, striped bass, and the sea lamprey. Catadromous fish migrate from fresh water down (Greek: κατά kata, “down” and δρόμος dromos, “course”) into the sea to spawn, such as eels.

Catadromous fish spend most of their lives in fresh water, then migrate to the sea to breed. This type is exemplified by eels of the genus Anguilla, numbering 16 species, the best-known of which are the North American eel (A. rostrata) and the European eel (A.

How are fish in the Mekong River being threatened?
Both fish production and species richness are now threatened by imminent construction of hydropower plants on tributaries as well as on the Mekong River itself ( 3, 9 ⇓⇓⇓ – 13 ).
How does the Se Kong River affect fish?
Beyond that, the construction of dams on the Se Kong River causes 1.3% productivity loss (∼8,200 tons/y) per TWh/y up to 88% hydropower production, and the LSS2 dam amounts to 4% of fish loss (∼25,300 tons/y) per TWh/y produced. The number of endangered species exhibits a similar trade-off with hydropower production ( Fig. 2 B ).
Where does the Tonle Sap fish migrate to?
The migration is closely connected to the seasonal flows of the river system. For most of the year, the Tonle Sap runs south for about 75 miles (120 kilometers) from the lake down to Phnom Penh, the Cambodian capital, where it joins the larger Mekong River.
