THE NUTRITIONAL RESPONSE OF TWO PENAEID SPECIES TO VARIOUS LEVELS OF SQUID MEAL IN A PREPARED FEED¹

Abstract

ABSTRACT Several pelletized feeds containing 30–35% total protein were tested on two penaeid species, Penaeus stylirostris and P. setiferus. Alginate bound test diets varied in protein composition but all diets contained about 30% sun‐dried shrimp meal. Following initial testing with diets containing up to 13% squid meal, further test diets varied in percentage of squid meal between 0 and 12.7, and in α‐soy flour between 0 and 12.4. One test diet replaced these components with 12.5% brewer's yeast. Conversion rates, survival, and growth were determined during a 3‐week period, both in the two species and in two sizes of P. stylirostris. Comparisons of the various diets between the two species suggest that the presence of 5–6% squid meal is advantageous in feeds of about 30–35% total protein.
