My father went fishing. Do you know what kind of fish this is?

Ranidae? The goby family, goby genus? Synechogobius？ fish

What is the picture below? ? Barracuda (Synechogobius hasta) is a kind of barracuda, commonly known as wave-pushing fish, quicksand fish, ground dragon fish, sky wave fish and light fish.

It is an annual warm-temperate coastal benthic fish with strong adaptability to temperature and salinity. Its meat is tender, delicious and growing rapidly. It is distributed along the coast of China, especially Lianyungang. The piranha is commonly known as "Shaguang Fish" in Lianyungang.

I can't stand the heat and high temperature in the south and the cold and frost in the north. I only live here. The mild climate and unique geographical environment in Lianyungang make sand fish a unique species with tender meat and thin skin. Every autumn is cool, the sand fish dives into the mud to lay eggs to avoid the cold after pregnancy. Only the eggs of grass coral survived hibernation under the protection of thick oocysts and began to reproduce in late spring.
