Evaluation of Feed Grind Size on Growth of Pacific White Shrimp ( Litopenaeus vannamei )
Fisheries and Aquatic Sciences Malha Ganesh
The Pacific White Shrimp Litopenaeus vannamei is a globally important species in aquaculture contributing approximately 25.7 billion dollars annually to international fishery product trade. Native to the western coast of Latin America, this species is commercially preferred due to its fast growth rate, tolerance to high stocking density, and low susceptibility to pathogens. The objective of this study was to determine if ingredient particle grind size had an effect on the growth performance of Pacific White Shrimp. Five experimental diets were formulated using identical ingredients and composition differing only in the particle grind size, ranging from 100 to 700 microns. This study was conducted over an eight-week period in an indoor recirculating aquaculture system. Juvenile shrimp were fed four times a day and water quality parameters were monitored and maintained within optimal levels across all treatments. Shrimps were weighed in batches every two weeks to assess growth and survival. All data were analyzed using ANOVA: Single Factor test to determine if grind size had a significant influence on growth. The results indicate that particle size did not have a significant effect on mean survival, weight gain, specific growth rate, feed conversion ratio, and feed intake. Understanding the relationship between feed particle size and growth performance is essential in helping feed manufacturers, shrimp hatcheries and farmers to increase production efficiency and optimize feed usage.
