High protein krill meal as a tool to optimize low cost formulas for juvenile Litopenaeus vannamei diets farmed under semi-intensive conditions

To investigate the potential of high-protein krill meal (HPK) to improve growth in low-cost diets for Pacific white shrimp (Litopenaeus vannamei), a commercial control and a 3% HPK diet were compared. To simulate a semi-intensive culture system, a total of 4,500 shrimp with a body weight (BW) of 3.0...

Description
Summary:To investigate the potential of high-protein krill meal (HPK) to improve growth in low-cost diets for Pacific white shrimp (Litopenaeus vannamei), a commercial control and a 3% HPK diet were compared. To simulate a semi-intensive culture system, a total of 4,500 shrimp with a body weight (BW) of 3.07 ± 0.01 g were stocked with 25 animals/m 2 in 20 cages in a 2.16-ha pond. After 60 days of rearing, the 3% HPK diet achieved a significantly higher yield (22,094.0 ± 130.35 g/cage) in comparison to the control diet (19,301.6 ± 272.28 g/cage) (P
