The present work looks at the effectiveness of microbound spray‐dried feed (MB‐SD) elaborated with two phycocolloids, sodium alginate (ALG) and kappa‐carrageenan (KAPACA), and no binder at all (SL). Feeding trials were carried out on larval Pacific white shrimp Litopenaeus vannamei from wild broodstock. Nauplii were stocked in 1.5‐L round‐bottomed flasks at a rate of 100 larvae/tank. Thirty thousand cells/mL (70% Chaetoceros muelleri and 30% Isochrysis galbana) were added to the artificial feed treatments as a single dose of live algae (SDLA) administered on the first day of the experiment. The MB‐SD was given at 6‐16 mg/L daily every 4 h from 0800 to 2000 hours. Water was not exchanged during the 10‐d experimental period. The MB‐SD with KAPACA gave the highest survival (61 ± 4.6%), good mean individual dry weight (104 ± 20.9 mg), and high metamorphic rate (81 ± 14%), followed by MB‐SD with ALG (56.9 ± 4.1% survival; 65 ± 10% metamorphic rate) and MB‐SD with SL (49.2 ± 6.2% survival; 76 ± 12% metamorphic rate). The latter feeds did not show a significant difference; however, they were slightly better than live food (algae plus brine shrimp Artemia sp.; 51.3 ± 7.9% survival; 52 ± 8% metamorphic rate). The MB‐SD with KAPACA provided good larval survival and growth and could be used in experimental larviculture.
