Love eating fish,but worry about the tiny bones(刺)?Chinese scientists have found an answer: using gene-editing(基因编辑).They have made a new kind of crucian carp(鲫鱼) without the small bones.

This special fish,named “Zhongke No.6”,was developed by a team at the Chinese Academy of Sciences,reported Xinhua.They found that the “runx2b” gene helps make the over 80 tiny bones in carp.Using gene-editing “scissors” called CRISPR/Cas9,they cut the runx2b gene very precisely.This way,the tiny bones never grow,but the main skeleton(骨架) does,said a lead researcher,as reported by online news website Interesting Engineering.

“The carp swims and grows normally and tastes just the same,” Gui Jianfang,the head of the team,told Guangming Daily.
Zhongke No.6 also grows faster and needs less food than the usual carp.This makes it possible for more products to be made from carp,like fish balls for hot pot,said Guangming Daily.
What’s more,scientists made sure that Zhongke No.6 cannot have babies.So even if these carp get into the wild,they won’t grow in number and take over the wild fish.
