Influence of Total Suspended Solids on the Growth of the Sea Lettuce Ulva lactuca Integrated with the Pacific White Shrimp Litopenaeus vannamei in a Biofloc System

A biofloc system is rich in nutrients, which favors the cultivation of macroalgae, but influence on performance macroalgae unknown. The objective this study was to analyze feasibility introducing Ulva lactuca into culture Litopenaeus vannamei a system. first experiment evaluated 400 mg L−1 and 30 solids concentration von Stosch medium growth. In second experiment, densities 1, 2, 3 g U. were cultivated an integrated with shrimp monoculture treatment. Both experiments had 35 days cultivation. There no significant difference growth between treatments medium. culture, density 1 showed better nutrient absorption. Shrimp not affected by conclusion, did affect it could be for nitrate uptake shrimp.
