IMTA

This repository contains data and R code accompanying the literature review Integrating plants improves aquaculture on the benefits that plants provide in integrated multi-trophic aquaculture (IMTA) systems.

The R code needed to perform the meta-analysis and plot the four figures is contained in the IMTA.R file.

Data files for each figure:

Figure 1

1. citations.csv: Web of Science citations report on "IMTA" and "IMTA AND (plant* OR seaweed* OR kelp* OR macroalga* OR alga*)".

2. findings.csv: Findings of plant-related IMTA papers categorised into positive, negative and neutral as well as primary purpose of plant integration.

3. plants.csv: Groups of plants and their co-cultured animals in IMTA systems referred to in the literature.

Figure 2

1. ammonium.csv: Reported ammonium uptake (μmol NH₄⁺ gDW^-1 h^-1) for different macroalgae with initial ammonium concentrations given in μM.

2. biofiltration.csv: Difference in biofiltration rate between macroalgae in monoculture and IMTA.

3. growth.csv: Difference in growth rate between macroalgae in monoculture and IMTA.

Figure 3

1. production.csv: Seaweed production in t and income in $ t^-1 for every country producing at least 130 t in 2017 (Reference: http://www.fao.org/3/ca5495t/ca5495t.pdf).

2. hypoxia.csv: Coastal zones of hypoxia (Reference: 10.1126/science.1156401).

3. Additional: Required area of seaweed farms to offset finfish and crustacean aquaculture (Reference: 10.1016/j.cub.2019.07.041) and change in mean sea surface temperature between present time and 2100 according to RCP8.5 (Reference: https://www.bio-oracle.org/downloads-to-email.php)

Figure 4

1. countries.csv: Seaweed production (Reference: http://www.fao.org/3/ca5495t/ca5495t.pdf) and number of papers (Web of Science) for all countries producing at least 130 t of seaweed and contributing to the scientific literature on plant-related IMTA.

2. seaweeds.csv: Seaweed production (Reference: http://www.fao.org/3/i9540en/i9540en.pdf) and number of papers (Web of Science) for all seaweeds that have a global production of at least 34×10³ t and appear in the scientific literature on plant-related IMTA.
