Abstract:The present study evaluated a polyculture system with Pacific white shrimp (Litopenaeus vannamei) and the macroalga Gracilaria birdiae and its potential to remove nutrients. The experimental design consisted of a shrimp monoculture of 100 animals/m2 (T0) and three multitrophic cultures with L. vannamei (100 animals/m2) and with G. birdiae at densities of 500 (T500), 1000 (T1000), and 2000 (T2000) g/m2. Nitrogen and phosphorus concentrations decreased at the beginning of the experiment in the treatments with ma… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
