Explain above all a bit, langouste can live in smelly ditch this is problem of a false appearance only. Why to want so say?
Although we see a few drain really in environment, especially those have more withered there is crayfish to live in the channel of died fireweed, but that cannot calculate smelly ditch absolutely. Can say that channel is dirtier only at most. If say crayfish can live in smelly ditch, a few meters of that channel Li Xiaolong after pond of that clear water says house of my uncle father the thing of shrimp changes.
Before soil smell still is being done not have in that channel, we are returned often thereinto angles crayfish. The crayfish inside is not little still. Cook later, wash clothes, others raised the mucky water of the pig to also swarm into this channel later, this channel with respect to worse and worse, water blackened, crayfish also is to decrease quickly. Begin some fish are returned inside moment, to later the fish also was done not have. When the water of whole channel blackens when smell, vivid content of the neither one in channel, shrimp neither one, more never mention it fish.
So, crayfish can survive in true smelly ditch is impossible almost. Reason, alleged smelly ditch must be black smelly. If say somebody sees there is crayfish to exist really in a little smelly ditch, explain this channel is not smelly ditch certainly on one hand, the water that we see may be color only deeper just, this shrimp is really enough on the other hand tenacious, quite fierce.
Be crayfish really nevertheless tenacious? Be not actually such. Before perhaps this channel was not changing, crayfish is more, but the crayfish after soil escaped in succession perhaps died. In environment, we are not to know what crayfish produced after all, former how many does the amount have. So, we saw the reality before only, there still is crayfish to live in channel, think crayfish can survive below such environments, little imagine everything is not had basically absolutely. These shrimp that perhaps at present sees are resistance is the strongest, and those weak or died, or escaped. This surviving rate can be had pity on lowly really.
Feel in breed crayfish mortality is tall, when to basically have: It is density big. Any animal high density breed is easier really occurrence disease. 2 it is we produce an activity to cause crayfish damage. Because often catch, so crayfish gets hurt easily. Plus us a kind of objective perception, namely we can be written down in the crayfish heart of pair of death in breeding a pond, and the crayfish utterly ignorant that dies in environment. This formed tremendous contrast -- the mortality in the pond is tall, and the outside is like dead shrimp of it doesn't matter.
Actually, should do well only in breeding a pool management, the surviving rate of crayfish is higher still, be the surviving rate that can achieve 75-80% usually.
Anyhow, crayfish can survive in smelly ditch, that is extremely individual crayfish ability is possible, this must not consult as one of crayfish breed aquatics standard, if for instance, that sure meeting crayfish breeds failure.
Does everybody say?
