Efecto de la supersaturación de oxígeno y tiempo de transporte sobre la supervivencia de huevos de huayaipe (Seriola rivoliana)

Abstract

Fish farming is key to the sustainable production of the aquaculture industry; however, it is not always possible to carry out all cultivation phases in the same production center. Therefore, it is necessary to acquire and transport "seed" (eggs, larvae, or juveniles) of the species to be cultivated from specialized fish reproduction centers such as CENAIM. This study proposes a safe protocol for transporting eggs of longfin yellowtail (Seriola rivoliana), a species with high commercial value and great cultivation potential. Factors such as water quality, oxygen levels, and travel duration affect embryonic and larval viability. Eggs from spontaneous spawning events of Huayaipe were collected using the traditional method, and the effects of supersaturation or hyperoxygenation and transport time on development and hatching quality were evaluated. The results showed that oxygen levels of up to 400% did not improve viability, and transport lasting more than 12 hours under uncontrolled conditions negatively affected the eggs. It is concluded that maintaining oxygen saturation between 100% and 200% optimizes the process, reduces costs, and improves transport efficiency, ensuring a more sustainable and viable method. Keywords: egg transport, hatching rate, longfin yellotail (Seriola rivoliana), oxygen saturation, transport efficiency.
