1987年,黑龙江省绥棱县水利科技人员,在气温较低的春季,利用棚增温保温的特点,成功地进行了孵化鲤鱼试验,缩短了鲤鱼孵化时间,做到了早分池、早放养、早培育,提高了鱼种规格,增加了鱼种产量。他们的做法是:在苗种培育池一侧选一面积为10米×7米的试验池,池上以塑料膜做棚。又将面积为8平方米的网箱放在苗种培育池内,做对照用。试验池和对照池经消毒处理后,注水75—85厘米深。从5月30日开始,两池都放入产卵巢(苫房草草帘),进行自然孵化。並定时观测水温,确保棚内水温昼夜都在27℃上下。在白天棚内水温过高时,采用注水和排水方法进行调温。据观测统计,试验池比对照池 In 1987, Suiling County, Heilongjiang Province, water conservancy scientific and technological personnel, in the spring the temperature is low, the use of shed warm insulation characteristics of the successful hatching carp test, shorten the carp hatching time, so early sub-pool, early stocking, Early breeding, raising the species specifications, an increase of fish production. Their approach is: Select a test area of ​​10 m × 7 m on the side of the seed culture pond, plastic shed to make shed. In turn an area of ​​8 square meters of cages on the breeding pool, so control purposes. After the test tank and the control tank were disinfected, the water was poured into 75-85 cm deep. From May 30 onwards, both pools are placed in the ovary (Hutulacao) for natural hatching. And regular observation of water temperature, to ensure that shed water temperature around 27 ℃ up and down. During the day shed temperature is too high, the use of water and drainage methods for temperature control. According to observation statistics, the experimental pool than the control pool
