SUPPLEMENTAL EFFECTS OF MICROALGAE SPIRULINA ARTHROSPIRA PLATENSIS TO THE PLANT-BASED DIET FOR PACIFIC WHITE SHRIMP Litopenaeus vannamei

Abstract

A sixty-days feeding trial was conducted to evaluate the inclusion effect of spirulina Arthrospira platensis meal (SM) in the diet on growth and health condition of juvenile Pacific white shrimp Litopenaeus vannamei. Four isonitrogenous and iso-lipidic experimental diets were formulated to contain 0%, 0,2%, 0,4% and 0,8% SM. After 60 days, shrimp were sampled and total haemocyte counts was measured. The growth performances of shrimp were significantly affected by the dietary inclusion of SM, whereas the inclusion of SM provides a better biomass, final body weight (FBW), weight gain (WG) and feed conversion ratio (FCR) compared to the control group. Additionally, the inclusion of SM significantly enhances the total haemocytes count (THC) and lysozyme activity in shrimp compared to control group. Therefore, SM can be considered as the functional ingredients in shrimp diet to improve the growth and health condition of shrimp.

Impact of dietary administration of Arthrospira platensis free-lipid biomass on growth performance, body composition, redox status, immune responses, and some related genes of pacific whiteleg shrimp, Litopenaeus vannamei

“…There are several forms of A. platensis supplementation in the diets of shrimp L. vannamei, such as dry powder form [33], whole-liquid extract form [34], nanoparticle form [13], derivative extract form [35] and lipid-free biomass. Each form has advantages and disadvantages.…”
