Mariculture
The reference point is based on harvested tonnes per coastal inhabitant (i.e. within the 25 Km
coastal strip). Yk is the 4-year moving window average for all k mariculture taxa that are currently or at
one time cultured within a country. Yearly harvested yield is based on a running mean with a 4-year
window of the harvest data. Given the very high skew in the status values per country, we set the
reference point to the 95th percentile region, with all regions above that value set to a status score
= 1.0.
STEP 1: Replace global taxa data with Yashika Fiji taxa data

STEP 2: Sustainability scores for Yashika Fiji taxa
The average global sustainability of shrimp and prawn species were averaged to estimate the
sustainability of these taxa in Fiji (shrimp_prawn_MSI_mean.csv).

STEP 3: Calculate new status and trend scores
Calculated using MAR.R script. Reference value (95th quantile) remained at 0.01472.
Status is based on 2011 data. For Fiji, trend was based on
