However, in our place, the old people called the blackfish "filial fish", said the reason is very unbelievable, that is, the female blackfish in the spawning after a period of time will become blind, can not see things, so the female blackfish at this time to find food, after all, the blackfish is to eat meat to catch other fish to eat, not see very lose, so this time to find food, after all, the blackfish is to eat meat to catch other fish to eat, not see very lose. Can't see is very disadvantageous, so this time, there will be a lot of blackfish hatchlings drilled into the mouth of the female blackfish, into food to return their mother.
The reproductive ability of the blackfish is very strong, a spawning can hatch out hundreds of blackfish, but in reality, the number of blackfish in a pond is very small, and part of the reason is that the blackfish fry are eaten by their own mother. Because the blackfish from the birth of nine-tenths destined to be eaten by their own mother, so the blackfish character is also very ferocious, can survive are great. The smaller blackfish usually move around the fishponds, eating small shrimp and other creatures, while also being eaten by other larger blackfish and whitebait, these fish.
When the blackfish grow up, they go to live in the middle and deeper of the pond, and this is the time when the blackfish start to kill, and even the catfish have a hard time escaping death. The most powerful is the adult blackfish will also catch blackfish fry to eat, so although the blackfish reproduction ability is strong, but the survival of the competitive pressure is very large, all the way down to survive the nine deaths. The biggest natural enemy during the fry is their own mother, adult blackfish, catfish and other fish, adult blackfish are mainly dead in the hands of other blackfish and people.
Blackfish live in freshwater, in freshwater, basically no natural enemies! If there may only Gan fish! Or larger old blackfish!
Gan fish is known as the king of freshwater, the same size Gan fish is not necessarily the same size blackfish opponent! Small blackfish attacked by big Gan is basically no way out! Gan fish is the initiative to attack the fish species! The blackfish just hit the ambush!
The blackfish is the same kind of fish species, the blackfish territorial consciousness is very strong, adult blackfish will ambush from its territory through a variety of fish! So young blackfish that stray into the territory are a bit of a worry!
Personally believe that the blackfish natural enemy only themselves and Gan fish!
It itself!
The big blackfish eat small blackfish, from the young fish began! And still the blackfish parents do! The name is test!
Newly hatched little blackfish by both parents to supervise the growth, the big blackfish catch and bite, let the little blackfish to the mouth to eat. A group of hundreds of small blackfish, below the protection of the big blackfish ---- strong reproduction!
Don't worry, here comes the test!
When the small blackfish grow to almost two inches long, it will face the graduation exam ---- still big blackfish in the mouth to chew food, let the small blackfish to eat!
The exam is ---- small blackfish to escape when the big blackfish suddenly close their mouths, or else they will be eaten by the big blackfish! Worth this, a nest of several hundred small blackfish can basically eat all, escape out of the top dozen ----- most cruel graduation exam! Then passed from generation to generation 。。。。。
So wild blackfish are ferocious, invincible existence!
I'm glad to answer this question, I grew up in the river according to my experience, in natural waters, the same amount of body, almost invincible, but the blackfish from childhood to adulthood, the growth process of countless natural enemies, such as a variety of waterfowl, a variety of carnivorous fish, in fact, the biggest natural enemy, is the human, you see my video will know, I caught a lot of them, [teeth bared]
What else is the natural enemy, it must be The human being ah, all kinds of pickled fish, spicy fish, ugh mom do not say, drooling
