The Colorado River Damming Impact on the Shrimp Fishery in the Upper Gulf of California, Mexico.Traduzido porLuis Cejudo-Espinosa. Frontera norte [online]. 2021, vol.33, e2137.  Epub 13-Set-2021.

The objective of this work is to demonstrate the relationship among the Colorado River flows and volumes of shrimp caught in the Upper Gulf of California (AGC). A correlation analysis was applied to historical series of data about landed shrimp catch, fishing effort and flow from the Colorado River towards the gulf. Dependence, proportionality, and linear relationship indicators were obtained. The main results showed that the interannual captures were lower in periods without water input from the river and higher with the water inputs to the estuary. In addition, the results showed that the contributions of nutrients carried in the river water to the estuary could increase the Carbon fixation. This study is important because it contributes to the discussion and strengthens the fact that this river is important in the environmental and fishing dynamics in the AGC.
