There has been various large-scale dredgers used for broad rivers, and the technique is already very mature, but producing such a dredger costs more than ten millions.

世界上已有的用于大型江河湖泊清淤的各种不同的挖泥船技术已经相当成熟，但制造这样一艘挖泥船所需成本高达上千万，而且它只能应用于作用面积极大的场合，对于水域狭窄的郊区、农村的沟渠、池塘和溪流以及堤岸死角等处的清淤就爱莫能助了。

I got up early and bathed in the pond; that was a religious exercise, and one of the best things which I did. They say that characters were engraven on the bathing tub of King Tching Thang (10)(10) to this effect:"Renew thyself completely each day; do it again, and again, and forever again."

At 3:42 am everything began to shake.It seemed as if the world was at an end!

The feature of this product is that diatom is taken as cereal or additional feed, so that stable and high yields can still be achieved even without feed or with 30 to 40 percentage of feed cut down; the outstanding social ecological economic benefits are brought by using this factory's products instead of medicines for curing disease in pond.

产品的特点是以硅藻作为主食或补食，对养殖体可免喂饲料或减喂饲料30-40％仍可稳产高产；对池塘病害不是以药物而是用本厂配套产品来进行生态治理，都具有显著的社会、生态、经济效益。

2Similar to other shrimps, artificial pond culture Penaeus monodon also had difference in growth between female and male. At early culture period, the difference between them was not distinct, but the female would grow more quickly than male after the fifty-ninth day. The body weight growth turning point of the male appeared at the 144.5 days, and at the 195. 3 days for the female.(3) By using Von Bertallanffy growth equation, the growth equations of Penaeus monodon were abtained.

养殖前期，雌、雄虾的体长、体重生长差异不明显，雄虾略高于雌虾，在59.6d后，雌虾体长生长速度高于雄虾；雄虾体重的生长拐点出现在144.5d左右，雌虾体重的生长拐点出现在195.3d左右；(3)采用von Bertallanffy生长方程，拟合出池塘养殖斑节对虾体长、体重生长方程为：。
