The wild population of South Pacific bonito , which has a wide distribution in northern Chile, is considered of importance in Chilean aquaculture. The biological feasibility of cultivation of any marine species begins with the establishment of an initial broodstock population to obtain eggs, larvae, and juveniles. In this work, 22 South Pacific bonito fishing campaigns were carried out in Pisagua, Chile, between spring in November 2011 and the summer in January 2012. At least 74 specimens were obtained of which 24 survived the capture and transport processes. Fish were stocked in a recirculating land-based aquaculture system, and at 14 months under captivity, fish began spawning. Eggs were collected, to describe some stages of development, and were placed in incubators at 20 °C and on the third-day eggs hatched. Larvae reached a total length between 1.435 and 1.7 mm, which were accurately characterized during their first morphological changes. This is the first work that describes the capture, transport, and acclimatization in captivity of a breeding population of wild Pacific bonito in Chile.
南太平洋狐鲣在智利北部分布广泛，其野生种群在智利水产养殖中具有重要意义。任何海洋物种养殖的生物学可行性都始于建立初始亲鱼种群以获取鱼卵、幼体和成鱼。在这项研究中，2011年11月春季至2012年1月夏季期间，在智利的皮萨瓜开展了22次南太平洋狐鲣捕捞活动。至少捕获了74尾样本，其中24尾在捕获和运输过程中存活下来。将鱼放养在陆基循环水养殖系统中，圈养14个月后，鱼开始产卵。收集鱼卵以描述其发育的一些阶段，并将其置于20℃的孵化器中，鱼卵在第三天孵化。幼体全长在1.435至1.7毫米之间，在其首次形态变化期间得到了准确描述。这是第一项描述智利野生太平洋狐鲣繁殖群体的捕获、运输和圈养驯化的研究。
