Effect of oceanographic variables and space-time factors on the density of Peruvian anchovy (Engraulis ringens): An approach with GAMLSS

Key Points

• Density of Peruvian anchovy is significantly influenced by various oceanographic variables, indicating complex ecological interrelations.
• The model revealed that spatiotemporal factors play a crucial role in predicting anchovy density, highlighting their importance in fisheries management.
• Using Generalized Additive Models for Location Scale and Shape, the analysis captures the nuanced relationships between environmental factors and fish density.
• Findings underscore the need for adaptive management strategies in fisheries to account for environmental variability and climate impacts.
