Project: Spatial dynamics analysis of shrimp fishery effort in the Gulf of California |

Shrimp
fishery is an economic activity defined by the costs and benefits of capture
operations. This fishery, with the greatest economic yield at national level,
has a strong socioeconomic impact in the states of Sonora and Sinaloa, which are the states
that contribute the most to national capture. However, shrimp fisheries have a
negative effect in the ecosystem because the trawling net used to capture
shrimp is scarcely selective, and causes damage to the marine species living in
sea bottoms where shrimp is captured.
We believe
that by understanding the mechanisms that take fishermen to decide where and
when to fish will provide us with a key tool to develop a management plan
capable of generating a sustainable and low impact fishery in the ecosystem to
maintain a high yield both in quantity and in quality of the employments and
currencies it generates for the country.
We will determine the consequences that space-time
closed seasons could have in total capture, economic yield, and employment
through the use of models that explicitly consider the costs and economic
benefits that derive from fishing in alternative fishing areas, each one of
them with a specific abundance of shrimp and with different distances to the
port of discharge, as well as with variable time in capture management. In this
manner we will be able to design a sustainable management plan that preserves
the fishing activity and the jobs it generates, maintaining and raising the
economic benefits of the fishermen, and reducing harmful effects to the
ecosystem.
