Abstract:
The Pacific yellowtail Seriola rivoliana belongs to the Carangidae family of fishes, along with several other species commonly cultures in Japan such as the yellowtail (Seriola quinqueradiata), Amberjack (Seriola dumerili) and striped Jack (Caranx delicatissimus). These species represent an important resource for recreational and commercial interests worldwide. Among other attributes, yellowtail is being targeted as an aquaculture species due their fast growth, excellent flesh quality and significant market opportunities internationally. In Ecuador some preliminary works have been conducted to produce the specie in captivity. To date it established a breeding population of captive Pacific yellowtail which spawn spontaneously and provide eggs on a daily basis during the spawning season. In spite of the resulting larval stages have been considered the bottleneck; the juvenile stages have been reared successfully on grown to 1 kg in 6 months. This work describes the most important considerations of rearing Pacific yellowtail larvae and juveniles in adapted shrimp production systems. In this point, the paper mentions extensively the basic rearing techniques and information of Seriola sp. biology; likewise, it identifies the specific technology requirements to commercial S. rivoliana aquaculture. In the other hand, some economic considerations are discussed to be able to operate under the reviewed culture conditions. All of this in order to provide an overall analysis about the attractive financial returns on invested capital.
