Abstract

A study was made to determine correlation between ingestion rate and survival of blue shrimp, Litopenaeus stylirostris check for this species in other resources , through its larval development when it was fed with different nutritional regimes. Shrimps were fed with four different concentrations of Chaetoceros calcitrans check for this species in other resources combined with Tetraselmis suecica check for this species in other resources and nauplii of Artemia franciscana check for this species in other resources . Results showed that the highest rate of ingestion and survival was obtained with a combination of 90x103 cél.·ml-1 of C. Calcitrans; 10x103 cél ·ml-1 of T. suecica and 6 nauplii·ml-1 of A. franciscana. It was found that a positive correlation between survival and ingestion rate exist in all larval stages, showing the highest correlation (r= 0,72) in transition from mysis 3 to postlarva 1. Significant correlation values were found in all cases (P<0.05).

Resumen

Se realizó un estudio para determinar la correlación que existe entre la tasa de ingestión y la supervivencia del camarón azul, Litopenaeus stylirostris check for this species in other resources , a lo largo de su desarrollo larvario al someterlo a diferentes regímenes alimentarios. Los organismos se nutrieron con cuatro diferentes concentraciones de Chaetoceros calcitrans check for this species in other resources en combinación con Tetraselmis suecica check for this species in other resources y nauplios de Artemia franciscana check for this species in other resources . Los resultados mostraron que el tratamiento en el que se observó una mayor supervivencia y tasa de ingestión fue donde se alimentó con 90x103 cél.·ml-1 de C. calcitrans en combinación con 10x103 cél.·ml-1 de T. suecica y 6 nauplios · ml-1 de A. franciscana. Se encontró que para este tratamiento existe una correlación positiva entre la supervivencia y la tasa de ingestión en todos los estadios larvarios, mostrando una mayor correlación (r =0.72) en la etapa de transición de misis 3 a postlarva 1. En todos los casos la correlación fue significativa (P<0.05).
