The crustacean culture is the third largest aquaculture industry with an annual production of 10.5 million tons in 2019 (FAO, 2023). Among the potential shrimp species, whiteleg shrimp (Litopenaeus vannamei) is native to the eastern Pacific Ocean and a highly desirable species for culture in many countries. Common basil (Ocimum basilicum L.) is a member of the Lamiaceae family which is cultivated commercially in many countries grows in several regions around the world and that has been extensively utilized in food as a flavoring agent (Sajjadi, 2006). Accordingly, it was necessary to throw some more light on using basil in shrimp farmed diets and study its effects on shrimp performance. Nutrition of western white leg shrimp is an area of research that has recently received considerable attention because of the influence of nutrition on growth and health as well as on cost of production. The present study was conducted to investigate the effects of basil extract, as growth promoters and feeding attractants; on growth, feed conversion, nutrient retention efficiencies, body composition, biometric measurement indices for L. vannamei.
