Utilising feed effectors and automated feeders for semi?intensive pacific white shrimp ( <i>Litopenaeus vannamei</i> ) production

Feed effectors have been suggested to improve the efficiency of plant-based shrimp diets by increasing attractability and palatability. This research trial aimed expand upon previous Pacific white (Litopenaeus vannamei) involving diets, feed passive acoustic monitoring (PAM) in a laboratory setting conducting outdoor semi-intensive ponds stocked at 30 shrimp/m2. A 13-week was conducted sixteen 0.1-ha equipped with PAM-integrated feeders, which allowed for demand-style feeding. Four soy-optimised consisting an ‘all-plant’ basal diet (AP) three attractant (2% krill meal (KM), 2% squid (SM), 4% fish hydrolysate (FH)), were fed period 74–75 days. Significantly more (p = 0.0131) FH respective than KM AP suggesting that addition increases intensity response cultured ponds. The same offered predetermined amounts outdoor, recirculating green water system resulted no significant differences > 0.05) between treatment means final weight or weekly growth rate.
