Anchovies are both marine and freshwater fish.

Anchovy is a migratory fish in rivers and seas. Anchovies usually live in seawater and migrate upriver in late spring and early summer for reproductive migration; young fish grow in rivers and lakes and generally reach a length of about 150 mm and enter the sea where they develop and grow. So anchovies are both marine and freshwater fish. Anchovies can survive in both fresh water and the sea. They are mainly found in the waters where the lower reaches of the Yangtze River meet seawater. This fish has an oblong body with a length of about 24cm. It has relatively high water temperature requirements and mainly eats plankton.

Life habits:

Shad are warm-water pelagic ocean fish that feed on plankton, mainly copepods, shrimps and diatoms. The feeding habits of each stage of life are slightly different. The larvae before landing in the sea feed on freshwater plankton; the young shad after landing in the sea feed on marine copepods and diatoms; the adult shad feed on marine copepods and diatoms. host.
