Abundance patterns for three species of penaeid shrimp off northwestern Mexico are explained based on sampling-catch data obtained by the National Fisheries Institute during closed fishing seasons (1995–2006).
The bathymetry and fishing area ( 14,000 km2) were determined from a depth dataset of 45,000 points.
The catch data were obtained from a sampling network of 62 sites, with an average of 76 trawls per fishing season; the brown shrimp (Farfantepenaeus californiensis) was the most abundant species.
The relative abundance models for the three s...
