Description
技术领域
本发明涉及水产养殖技术领域,具体涉及一种淡水活鱼运输管理方法。
背景技术
鱼类是水生低等变温脊椎动物,容易受外界环境的干扰,活鱼运输是鱼类养殖、销售环节中重要的步骤之一,运输过程中鱼类因环境改变、活动空间较小、运输过程中碰撞摩擦等原因会出现惊恐症状,排出较多的氨与粘液污染运输水质,而活鱼运输期间又不能及时换水,水质污染对鱼体健康危害比较大,往往导致运输目的地到达时,会有大量的死鱼出现。
发明内容
为解决由于活鱼运输期间受到惊恐而出现排出较多的氨与粘液污染运输水质的问题,本发明提供一种淡水活鱼运输期间管理方法。
本发明淡水活鱼运输管理方法由以下步骤组成,
将活鱼装入运输箱,每升水容纳500-600g活鱼,活鱼运输期间,每隔一小时,调整一次水中溶解氧,水中溶解氧含量在8-10mg/L~~3-5mg/L之间来回调整。
比如,运输开始第一小时内,水中溶解氧含量调整在8-10mg/L之间,则运输开始第一至第二小时内,水中溶解氧含量调整在3-5mg/L之间,运输开始第二至第三小时之间,水中溶解氧含量依旧调整在8-10mg/L之间,运输开始第三至第四小时之间,水中溶解氧含量继续调整在3-5mg/L之间,以此类推,水中溶解氧含量每小时调整一次,第n小时调整范围在8-10mg/L之间选择,第n+1小时调整范围在3-5mg/L之间选择,n为自然数,n不包括0。
本发明通过在活鱼运输期间调整水中的溶氧量,使活鱼在运输期间维持在临界昏迷状态而又不会致死,保证活鱼的新陈代谢维持在最低水平,可避免活鱼因惊恐排出较多氨与粘液污染水质,提高活鱼运输存活率,方法简单可靠,对活鱼无任何副面影响。
具体实施方式
以下为本发明部分实施例, 本发明在实施时并不仅限于以下实施例所列举的范围,
实施例1,将活鱼装入运输箱,每升水容纳500g活鱼,活鱼运输期间,每隔一小时,调整一次水中溶解氧,水中溶解氧含量在8mg/L与3mg/L两个数值中来回调整。
比如,运输开始第一小时内,水中溶解氧含量调整在8mg/L,则运输开始第一至第二小时内,水中溶解氧含量调整在3mg/L,运输开始第二至第三小时之间,水中溶解氧含量依旧调整在8mg/L,运输开始第三至第四小时之间,水中溶解氧含量继续调整在3mg/L,以此类推,水中溶解氧含量每小时调整一次,第n小时调整至8mg/L,第n+1小时调整至3mg/L,n为自然数,n不包括0。
实施例2,将活鱼装入运输箱,每升水容纳600g活鱼,活鱼运输期间,每隔一小时,调整一次水中溶解氧,水中溶解氧含量在10mg/L与5mg/L两个数值中来回调整。
比如,运输开始第一小时内,水中溶解氧含量调整在10mg/L,则运输开始第一至第二小时内,水中溶解氧含量调整在5mg/L,运输开始第二至第三小时之间,水中溶解氧含量依旧调整在10mg/L,运输开始第三至第四小时之间,水中溶解氧含量继续调整在5mg/L,以此类推,水中溶解氧含量每小时调整一次,第n小时调整范围在10mg/L,第n+1小时调整范围在5mg/L,n为自然数,n不包括0。
实施例3,将活鱼装入运输箱,每升水容纳550g活鱼,活鱼运输期间,每隔一小时,调整一次水中溶解氧,水中溶解氧含量在9.1mg/L~~4.3mg/L两个数值中来回调整。
比如,运输开始第一小时内,水中溶解氧含量调整在9.1mg/L,则运输开始第一至第二小时内,水中溶解氧含量调整在4.3mg/L,运输开始第二至第三小时之间,水中溶解氧含量依旧调整在9.1mg/L,运输开始第三至第四小时之间,水中溶解氧含量继续调整在4.3mg/L,以此类推,水中溶解氧含量每小时调整一次,第n小时调整范围在9.1mg/L,第n+1小时调整范围在4.3mg/L,n为自然数,n不包括0。
该法由两个阶段构成:
当水中含氧量在8-10mg/L之间时,活鱼可维持正常生存状态,当水中含氧量在3-5mg/L之间时,活鱼几近昏迷,但可以在此含氧量之间安全维持1小时,继续将水中含氧量调整至8-10mg/L之间时,活鱼又会逐渐苏醒,恢复正常,反复使活鱼逐渐昏迷,逐渐苏醒,保证活鱼在运输过程中新陈代谢达到最低状态。
以下结合具体实验对本发明进行说明,
1、捞取重量在200-500g、无病害的鲫鱼100尾,捞取前一天不进行喂食,鲫鱼捞取后装入运输箱,水中含氧量在8mg/L~~3mg/L这两个数值之中来回调整,模拟运输环境,经检测,鲫鱼在72小时内,存活率可达到100%。
2、捞取重量在500g左右、无病害的鲤鱼100尾,捞取前一天不进行喂食,鲫鱼捞取后装入运输箱,水中含氧量在9mg/L~~4mg/L这两个数值之中来回调整,模拟运输环境,经检测,鲫鱼在72小时内,存活率可达到100%。
3、捞取重量在1kg-2kg、无病害的鳙鱼100尾,捞取前一天不进行喂食,鲫鱼捞取后装入运输箱,水中含氧量在10mg/L~~5mg/L这两个数值之中来回调整,模拟运输环境,经检测,鲫鱼在72小时内,存活率可达到100%。
