Is pike a sea fish or a river fish?

Barracuda is an offshore fish, native to South China Sea, East China Sea, Yellow Sea and Bohai Sea in China. Barracuda mainly lives in coastal areas, river estuaries or salt water. Love to live in groups and have a wide range of feeding habits, belonging to omnivorous fish with plant feed as the main source. Mainly scraping benthic diatoms and organic debris deposited on the surface of sediments, but also eating some filamentous algae, decapods, polychaetes, mollusks and shrimps.

The habits of barracuda:

1, wide salt. Barracuda can live in 35% high salinity seawater to 5% freshwater shallow seas, estuaries, salt ditches, inland saltwater lakes, freshwater lakes and ponds. No matter what the sediment is, it can not only survive in plain waters, but also grow in high-rise waters with an altitude of 1470 meters.

2. Wide temperature range. The water temperature can tolerate 0-35℃, and the optimum growth temperature is 18-28℃. Barracuda can adapt to the change of water temperature only when the temperature gradually slows down. If the temperature suddenly rises and falls in a short time, it will cause death. In addition, pike has great ecological tolerance to oxygen, and its oxygen consumption increases with the increase of individuals.

3. Eating habits. Barracuda has a wide range of feeding habits and belongs to omnivorous fish with plant-based food. Mainly scraping benthic diatoms and organic debris deposited on the surface of sediments, but also eating some filamentous algae, decapods, polychaetes, mollusks and shrimps.

4. Wandering. Barracuda is a semi-migratory fish near the shore, which has no long-distance swimming phenomenon, but can migrate in a short distance and a small range with the season, water temperature and its own development. Finfish often inhabit shallow seas or estuaries with a water depth of 1 ~ 3 meters. When the weather gets cold, they will swim to the deep sea for the winter. However, some individuals also overwinter in deep bays and shallow seas.
