福建漳州地区金刚虾(Penaeus monodon)养殖特性、存在问题和对策措施

    Characteristics, existing problems and countermeasures of diamond shrimp culture (Penaeus monodon) in Zhangzhou City, Fujian Province

    • 摘要: 2021年4—12月,针对福建省漳州地区金刚虾(斑节对虾)养殖情况,现场调研了68家典型养殖户和分析了265份问卷调查表。结果表明漳州地区气候温和,日照时间长,适合金刚虾养殖。漳州地区金刚虾养殖模式主要为土塘和高位池养殖,土塘养殖模式主要分布在龙海区和漳浦县,一年2~3茬,采用地下水+盐卤调配至养殖盐度3~10,养殖密度为(1.50~4.50)×105ind/hm2,存活率为73.90%,饵料系数为1.63,养殖产量为(0.38~0.98)×104 kg/hm2,利润为(1.20~12.75)×104元/hm2。高位池养殖模式主要分布在漳浦县、东山县和诏安县,一年2~3茬,养殖用水采用自然海水,盐度20~30,养殖密度为(1.50~6.00)×106ind/hm2,存活率为74.58%,饵料系数为1.84,养殖产量为(0.83~10.20)×104 kg/hm2,利润为(3.53~11.09)×105元/hm2。漳州地区金刚虾虾苗生产量逐年增加,从2017年金刚虾虾苗生产量占对虾虾苗生产总量的7.76%提升至2020年的39.41%,2021年稍有下降,为32.46%。目前漳州地区金刚虾养殖存在从业人员基础差、年龄偏大,可选养殖品种单一,高位池养殖密度盲目提高,尾水处理难度大等问题。对此,建议加强金刚虾养殖技术的培训和新型农民的培养,提高养殖户的管理水平;采用精细管理,提高养殖效益,推广"白+黑(凡纳滨对虾+斑节对虾)"健康养殖模式,促进金刚虾可持续健康发展。

       

      Abstract: From April to December in 2021,68 typical farms and 265 culture questionnaires of diamond shrimp (Penaeus monodon) were investigated in Zhangzhou City,Fujian Province.The results showed that there were mild climate,long sunshine time and long coastline in Zhangzhou,which was suitable for the shrimp culture.The mainly diamond shrimp culture mode in Zhangzhou were using soil pond and higher place pond,where were mainly distributed in Longhai District,Zhangpu County,Dongshan County and Zhao’an County,respectively.There were 2-3 times harvests a year which the stocking density,survival rate,feed coefficient,output and profit were(1.50-4.50)×105ind/hm2,73.90%,1.63,(0.38-0.98)×104 kg/hm2 and RMB(1.20-12.75)×104yuan/hm2 in 3-10 salinity mixed by groundwater and bittern in soil pond,respectively.There were 2-3 times harvests a year too,which the stocking density,survival rate,feed coefficient,output and profit were(1.50-6.00)×106ind/hm2,74.58%,1.84,(0.83-10.20)×104 kg/hm2 and RMB(3.53-11.09)×105yuan/hm2 using 20-30 salinity natural seawater in higher place pond,respectively.The production of diamond shrimp larvae was increased year by year in Zhangzhou which the increase amount were 7.76% to 39.41% from 2017 to 2020.There was a slightly decline by 32.46% in 2021.At present,the basis and age of the employees of diamond shrimp farmers were poor and old in Zhangzhou,respectively.There was a single specie for selection.The stocking density of higher place pond had been blindly increased,and the aquaculture tailwater was difficult to be treated.The fine management was employed to improve the breeding efficiency,and the "white + black(Litopenaeus vannamei + P.monodon)" healthy breeding mode was popularized for promoting the sustainable and healthy development of diamond shrimp culture.
