Preferential behavior of white shrimp Litopenaeus vannamei (Boone 1931) by progressive temperature–salinity simultaneous interaction

For different combinations acclimation temperature–salinity of shrimp (Litopenaeus vannamei) the preferred temperature range was from 26.1 to 31.4 °C without salinity effect.Shrimp acclimated at 10‰ and 19‰ preferred salinities higher than those to which they were acclimated. However, shrimp acclimated at 28‰ and 36 ‰ preferred lower salinities than those to which they were acclimated. This behavior was associated with the selection of a higher temperature.Behavioral studies of organisms exposed to experimental environmental gradients allowed the establishment of optimal cultivation conditions of L. vannamei.
