The network spreads the steamed crab and feeds and uses contraceptives Put the density in a suitable place to breed high or use hormone
Hubei is that a crab cultivates the large province, the crab that produces every year is not merely popular at home, still find a good sale abroad. The crab will go on the market shortly soon, but one will say that makes heart li of many persons who have a liking for crabs uneasy on the network: There is a large amount of antibiotic in the delicious steamed crab, some steamed crab is even thrown something and fed hormone articles such as contraceptive,etc.. How on earth did the crab form? Yesterday, the reporter went to the largest crab producing region of Hubei - -The roof beam sub lake of summer of river is visited.
" we do not need to throw in the bait "
In the crab cultivating area chewed in sub Hubei of roof beam of summer of river - -Organic aquatic products crab's cultivation base of 6666.667 hectares, can see on the broad lake surface, aquatic weed and boundary network that mostly floated, can not see crabs.
"Crab in 4-6 meter dark bottom, only certainly watch crabs from the surface of water. " The roof beam sub lake minister of project department of aquatic products group Cheng QingWu of Wuhan accompanying it introduces, Liang ZiHu cultivates the greatest characteristic of the crab, puts in a suitable place to breed naturally, in the water areas of area of 0.067 hectares, generally only raise the crabs about 20 pieces, the culture of so rare density, even if the lake water can be seen through to the end at one glance, in area (about 666.7 square meters) of 0.067 hectares Water areas in, very it is difficult find by 20 figure of crab.
He says, just because sub lake crab puts the roof beam in a suitable place to breed naturally, and it is relatively small to cultivate the density, the crab that the natural ecological chain guarantees to feed enough has sufficient food sources in the lake water, so does not need to throw in the artificial baits, does not just use and throw something and feed situations such as antibiotic,etc..
Using antibiotic will raise the cost
Group's Chairman of aquatic products of sub lake holds the doctrine and refutes the rumor on net in terms of economic cost with roof beam. He says, if feed crabs in a area relatively smaller pond, no matter throw in antibiotic or rotten animal's corpse in the pond, the quantity can not be numerous.
But the crab that the roof beam sub lake is cultivated, puts in the large water areas of sub lake of roof beam and puts in a suitable place to breed, only take cultivation base of 6666.667 hectares as examples, want to throw in antibiotic or rotten animal's corpse in such large water areas, how much must be thrown in then to work?
In other words, if want to throw in antibiotic in water areas of 6666.667 hectares, and it dilutes density and can play the words of function to the crab, it is much higher than the expenses which cultivate the crab to only buy the expenses of antibiotic, consider from cultivating cost view, will not throw in articles such as antibiotic,etc. in the water areas putting so by a large scale in a suitable place to breed either.
The crab of Hubei has strict standard of measurement
If the roof beam sub lake crab wants to go on the market, must pass the quality testing of the relevant department. Cheng QingWu claims, there are many check organizations of the roof beam sub lake crab, the standard is strict, " can not be problematic " .
Cheng QingWu says, the crab that Liang ZiHu exported should all enter and leave the border to quarantine in the technique center of the office to measure in Hubei, these crabs are besides measuring according to standard of export inspection and quarantine of our country, also measure at the request of crab's exporter, for example export to South Korea and demand to check something, what is exported to Japan and demanded to check, up to forty or fifty kinds detection projects of some countries, "and they come here to inspect by random samples at ordinary times, measure the project each time differently.
