对在养蛏池内直接施肥培养饵料的传统缢蛏池塘蓄水养殖模式进行优化,建立了以专用池塘培养缢蛏生物饵料的池塘养蛏系统,即独立供式缢蛏池塘蓄水养殖系统。经过5个月左右养殖试验,独立供饵式缢蛏池塘蓄水养殖系统缢蛏平均单产为3226.8 kg/ha,分别比传统缢蛏池塘蓄水养殖(2个对照组)提高37.37%和34.20%;生长速度分别快32.3%和38.7%,商品平均规格为16.13 g/粒,规格较整齐;养殖存活率为66.7%,与对照组差异不大;单位经济效益为5.48万元/ha,分别是对照组的270.26%和226.73%。与传统养殖模式相比,该独立养殖系统具有饵料供应充足、养殖生长速度快、经济效益高等优点,至少缩短了1个多月的养殖周期,避免了高温期对缢蛏养殖的危害。
對在養蟶池內直接施肥培養餌料的傳統縊蟶池塘蓄水養殖模式進行優化,建立瞭以專用池塘培養縊蟶生物餌料的池塘養蟶繫統,即獨立供式縊蟶池塘蓄水養殖繫統。經過5箇月左右養殖試驗,獨立供餌式縊蟶池塘蓄水養殖繫統縊蟶平均單產為3226.8 kg/ha,分彆比傳統縊蟶池塘蓄水養殖(2箇對照組)提高37.37%和34.20%;生長速度分彆快32.3%和38.7%,商品平均規格為16.13 g/粒,規格較整齊;養殖存活率為66.7%,與對照組差異不大;單位經濟效益為5.48萬元/ha,分彆是對照組的270.26%和226.73%。與傳統養殖模式相比,該獨立養殖繫統具有餌料供應充足、養殖生長速度快、經濟效益高等優點,至少縮短瞭1箇多月的養殖週期,避免瞭高溫期對縊蟶養殖的危害。

This study aimed to optimize the traditional farming model ( direct fertilization for natural live organism cultivation ) of Sinonovacula constricta, and a Sinonovacula constricta farming system was established, which applied specific ponds for natural live organisms cultivation. The results showed that after 5 months farming, the average yield of this farming system was 3 226.8kg/ha, which increased by 37.37% and 34.20% higher than that of the two control groups ( traditional farming models) . The average market size was 16.13 g per individual and very uniform, and the growth rate was faster than the two control groups by 32.3%and 38.7%, respectively. The survival rate was 66.7%, with no significant difference with the control groups. The unit economic benefit of the system was RMB 54 800/ha, which accounted for 270.26% and 226.73% of the two control groups. In conclusion, compared to the traditional farming system of Sinonovacula constricta, the optimized faming system with independent feed supply and water storage ponds possesses the advantages of more sufficient supply of natural live organisms, fast growth rate and high economic benefit. And this system can at least reduce over 1 month of the production cycle, and the damages to Sinonovacula constricta in high temperature period can be avoided.
