The value of fisheries in the Upper Gulf of California

In April 2015, a temporary suspension of fishing with gill nets in the Upper Gulf of California came into effect, as part of the effort to protect the most endangered cetacean in the world, the vaquita marina (DOF 2015). The incidental death of vaquitas in gill nets is the main cause of the species’ population...

Tying it all together

The Gulf corvina (Cynoscion othonopterus), a large marine fish endemic to the Upper Gulf of California, whose migration to its only known spawning grounds in the Colorado River Delta, supports one of the most productive artisanal fisheries in Mexico. Gulf corvina aggregate to spawn in the shallow estuaries and channels of the Delta from late...

How much does it cost to fish?

Understanding the economic costs of fishing is important in order to evaluate the long term potential of a fishery for local communities. It also gives us an idea of how the fishery may continue to exploit a specific resource. For example, if a fishery is losing money (spending more on gear and fuel than it...

Fishing vessel movement: recording Mexico’s fishermen

Collecting spatial information on the movement of fishing vessels and the deployment of fishing gear allows scientists to better understand the geographical distribution of fishing activities. By partnering with fishermen and local communities, the Gulf of California Marine Program (GCMP) has been able to develop a system that can record the fishing activity of Mexico’s...

Trackers: What is Trackers Program?

One of the objectives of the Gulf of California Marine Program is to understand the relationship between fisheries and biodiversity in marine and nearshore ecosystems in the Gulf of California. To pursue this objective, we require establishing relationships with the communities involved, which use and understand the environment in which they work. For this purpose we created the Trackers Program, whose main objective is to collect spatio-temporal information related to fisheries that will help understand these relationships. The Trackers Program is a project composed of many research groups and communities that is supported by the Gulf of California Marine Program. The main objective is to work with the communities in an attempt to understand de health status of the most important fisheries resources and their relationship with their habitats.
