ABSTRACT
Penaeus monodon is the most widely agricultured species in the prawn industry Two-thirds of prawn consumed annually come from farming Since then, the aquaculture industry has been growing. but unfortunately, fishmeal, which has been the primary feed used for prawn rearing has gradually decreased in production Due to the lack of supply of fishmeal, researchers have conducted studies to find alternative feeds for the prawns.
It is essential for a feed to contain attractant properties in order for it to lure the prawn into eating the feed, thus utilizing the nutrients it contains. This study determines which feed ingredients among various sources of proteins, carbohydrates and oils exhibit the best attractant properties among other ingredients of the same type of source.
One-way Analysis of Variance (ANOVA) showed that Rice Flour exhibited the best attractability among the carbohydrate sources with mean prawn travel time of 1496.42 seconds. Among the plant oils was the soybean oil (1513s). Among the animal oils was the chicken fat (1337.83 s.) and Squid Liver Meal (272. 75 s) among dried protein sources.
