The transport of live fish is a crucial step to establish fish culture in captivity, and is especially challenging for species that have not been commonly cultured before, therefore transport and handling methods need to be optimized and tailored. This study describes the use of tuna tubes for small-scale transport of medium-sized pelagic fish from the Scombridae family. Tuna tubes are an array of vertical tubes that hold the fish, while fresh seawater is pumped up the tubes and through the fish mouth and gills, providing oxygen and removing wastes. In this study, 19 fish were captured using rod and line and 42 % of the captured fish were transported alive in the custom-designed tuna tubes to an on-shore holding tank: five mackerel tuna (Euthynnus affinis) and three leaping bonito (Cybiosarda elegans). Out of these, just three (15.8 % of total fish) acclimatized to the tank's condition. Based on these results, we discuss an improved design of the tuna tubes that has the potential to increase survival rates and enable a simple and low cost method of transporting of live pelagic fish.
活鱼运输是圈养鱼类养殖的关键环节，对于以前未普遍养殖的物种而言尤其具有挑战性，因此运输和处理方法需要优化和定制。本研究描述了金枪鱼管在小规模运输鲭科中型中上层鱼类中的应用。金枪鱼管是一系列垂直的管子，用于容纳鱼类，同时将新鲜海水泵入管中并通过鱼嘴和鳃，提供氧气并清除废物。在本研究中，使用钓线捕获了19条鱼，其中42%的捕获鱼通过定制设计的金枪鱼管活着运到岸上的暂养池：五条鲣（Euthynnus affinis）和三条长腰鲔（Cybiosarda elegans）。其中，只有三条（占总鱼数的15.8%）适应了池塘环境。基于这些结果，我们讨论了金枪鱼管的改进设计，该设计有可能提高存活率，并实现一种简单且低成本的活中上层鱼类运输方法。
