Persistence index of juveniles of Parapenaeus longirostris in the Portuguese continental coast
This Persistence index of juveniles of Parapenaeus longirostris in the Portuguese continental coast was calculated following Colloca et al. (2015) for project Minouw.
Using data from PT-IBTS (2002-2011), geostatistical methods were performed for each year. Density hot spots were outlined on the annual maps using Hot Spot Analysis (Getis-Ord Gi*) and persistente zone of undersized indivuduals was calculated for the overlapped years.
