Supervivencia de postlarvas de litopenaeus vannamei a dos densidades sostenidas con cuatro estrategias de alimentación durante la simulación de un transporte de 12 horas.

Abstract

The production of white shrimp Litopenaeus vannamei in Ecuador is a key sector for the economy, generating significant income and employment. This study evaluated the survival of postlarvae under two transport densities (1.5 g/L and 3.0 g/L) and four feeding strategies during a 12-hour simulated transport. The results showed that postlarvae fed with flake and with a combination of flake and yeast achieved the highest survival rates in both densities. Additionally, higher ammonium levels were observed in the higher density treatments, ranging from 2.10 mg/L to 1.67 mg/L, highlighting the importance of controlling these parameters to optimize postlarvae viability during transport. These findings suggest that the use of flake as feed, either alone or complemented with yeast, is the most effective strategy to improve postlarvae survival during shrimp transport.
