Effect of carbohydrate types on water quality, proximate composition and glycogen content of white shrimp juvenile Litopenaeus vannamei (Boone, 1931)

Abstract

Vannamei shrimp is one type of penaeid shrimp that has fast growth, resistance to disease and tolerance to changes in water quality. In farming vannamei shrimp, feed is an important factor because the largest production cost comes from the purchase of feed. One way to reduce feed costs is to reduce the protein component and increase the carbohydrate component in feed formulation. This study aimed to examine the effects of various types of carbohydrates on water quality, proximate composition and glycogen content of juvenile vannamei shrimp. The study was designed with a complete randomized design with four treatments and three replicates. The carbohydrate treatments consisted of A. corn flour, B. sweet potato flour, C. rice bran flour and D. wheat flour. The shrimp seed used in this study were stadia PL25 juvenile vannamei shrimp. The feed was given at a rate of 10% of shrimp body weight with a frequency of four times a day. The results showed that the type of carbohydrate in the feed had significant effect on water quality, proximate composition and vannamei shrimp glycogen levels. Carbohydrate from sweet potato flour gave the best results compared with the other treatments.
