Plankton Density in Shrimp and Tilapia Polyculture, 95-Day Experiment

Luís Otávio Brito conducted a 95-day experiment evaluating plankton densities in polyculture systems of Pacific white shrimp (Litopenaeus vannamei) and Nile tilapia (Oreochromis niloticus). The study used a randomized design with three treatments and four replicates, measuring phytoplankton densities from 78,981 to 303,260 cells per mL and zooplankton from 470 to 1,421 organisms per L. The most frequent groups identified were Bacillariophyta (phytoplankton) and Rotifera (zooplankton).

Use Cases

• Analyzing the impact of different shrimp-to-fish stocking ratios on plankton communities based on the described experimental treatments.
• Modeling phytoplankton and zooplankton population ranges in closed, non-aerated aquaculture systems based on the provided density measurements.
• Comparing plankton group frequencies, such as Bacillariophyta and Rotifera, across monoculture and polyculture conditions.

Strengths

• Experimental design is explicitly described with three treatments and four replicates each.
• Provides concrete, measured ranges for phytoplankton (78,981–303,260 cells.mL⁻¹) and zooplankton (470–1,421 org.L⁻¹) densities.
• Identifies the most frequent plankton groups (Bacillariophyta and Rotifera) from the study.
