Effects of dietary protein level and source on the growth and survival of two genetic lines of specific-pathogen-free Pacific white shrimp, Penaeus vannamei

► This is an initial study of potential interaction between genetics and nutrition. ► Diets containing different protein sources yielded similar growth and survival. ► Two shrimp lines grew similarly regardless of dietary protein levels or sources. ► Dietary plant protein level interacted with shrimp line on survival.
