摘 要:为探索盐碱地池塘养殖斑节对虾的适宜放养密度,在条件、面积相同的盐碱地池塘,消毒、肥水后,斑节对虾标粗苗放养密度分别为10.5万、15万、19.5万、22.5万尾/hm^(2),养殖3个月后,以养成规格、成活率、生长速度、产量和效益等作为评价指标加以比较分析。研究结果表明,在10.5万至22.5万尾/hm^(2)放养密度范围内,随着密度增加,对虾规格逐渐变小,成活率降低,虽然产量有所提高,但因小规格对虾售价偏低,养殖利润较少。10.5万尾/hm^(2)密度条件下,对虾成活率高、规格大、售价高,利润最高;15万尾/hm^(2)密度条件下,产量较高,规格和价格在当地市场接受度高,利润略低,养殖业主也可根据当地市场情况考虑选择适宜养殖密度。In order to explore the appropriate stocking density for the cultivation of the shrimp Penaeus monodon in saline-alkali ponds with the same condition and area,after disinfection and fertilization of the water,the large fries of the shrimp were cultured under the stocking densities of 105000,150000,195000,and 225000 ind./hm^(2),respectively,the harvest size,survival rate,growth rate,yield,and profit were used as evaluation indicators for comparative analysis.The results showed that in the range of stocking density of 105000~225000 ind./hm^(2),the harvest size and the survival rate of the shrimp gradually decreased with the increase of the stocking density.Although the yield increased,the profit was less due to the lower price of small-sized shrimp.Under the stocking density of 105000 ind./hm^(2),the survival rate of the shrimp was high,the harvest size was large,the price was high,and the profit was the highest.Under the stocking density of 150000 ind./hm^(2),the yield was higher,the harvest size and price were accepted by the local market,and the profit was slightly lower.Thus the appropriate stocking density can also be decided according to the local market.
