FIDES works with schools in the assessment and recovery of ancestral knowledge of mangrove people, through training workshops in schools and colleges, and cardisima events, such as drawing competitions, speech contests, murals, among other activities.
Their main activities include:. In Ecuador, mangroves, estuaries, rivers and beaches are national assets for public use, and the law decrees free passage in these areas. Dead crab found three days after repopulation. Data registration before repopulate of crabs. As a pilot project, these processes include the use of both ancestral knowledge from communities, and scientific knowledge from professionals.
The basic conditions necessary include that the site is located near a body of water and has plants used for food by crabs, such as romero Sesuvium portulacastrumstraw Cyperus rotundusranconcha Acrostichum aureum and others.
Napa works in community tourism, and promotes organizational strengthening and mangrove restoration activities in communities. There has crssum yet been an assessment of the results; however, quarterly monitoring suggests an increase in population density in the reintroduction sites and in other areas due to crab movement, or individuals seeking new breeding sites.
The disadvantage of this cardisomx method is that you cannot identify the sex ratio of crabs. Produce leaf litter and export biomass Stabilizes microclimates: The process of ecological restoration of mangrove ecosystems in the Chone River estuary first requires a series of activities to reduce the main causes of deterioration, including mangrove restoration, which allows for the recovery of optimal conditions to recuperate the productive capacity of the ecosystem and its ecological functions.
Part of a quadrant used for indirect sampling in Community Portovelo. As a women leader to the Ecuadorian people living catdisoma mangrove communities, Mrs. As additional measures, it is prohibited to catch crabs with sizes smaller than 7.
The main problems faced by these families are:. Her experience includes working with local rural communities in strengthening community organizations and economic activities, protected areas management, and mangrove ecosystem restoration. Before reintroducing crabs in their new site, temporary artificial burrows are created with a one meter depth so that the crabs can use them until they are able to make their own burrows or choose to stay in the artificial one.
A boy returning the crab to its respective burrow. For example, before the shrimp industry took over, on average shell Anadara similis and Anadara turberculosa were collected per day, which currently less than 50 shells are collected per day. It is unlikely that cradisoma policies and authorities are able to resolve all cagdisoma the issues highlighted above in the short term; however, it is important cardissoma promptly initiate actions for ecosystem restoration.
Reduce the salinity of water entering mainland Source of organic matter: In addition to their ecological role, mangrove forests fulfill many economic, cultural and social functions. Growing participation in these families allows for the following:. Due to the degradation of the mangrove ecosystem within the estuary, and continued shrimp industry activities which occupy almost the entire area that was historically mangroves and salt ponds, it is difficult to conduct a thorough restoration process; However, the FIDES Foundation and local communities implement restoration processes in certain areas through red mangrove reforestation Rhizophora mangleand recovery of mangrove species such as shell Anadara similis and Anadara tuberculosa and craxsum crab Cardisoma crassum.
It is terrestrial and live in Czrdisoma burrows which are one cafdisoma two meters deep, built in drier soils within mangrove forests and in transition areas of humid or dry forests, as long as there is a brackish water source nearby. Even so, similar to other species in mangrove forests, the survival of the mouthless crab is negatively affected by mangrove destruction and overexploitation. Several communities are situated on the banks of mangroves, and these people engage in activities dependent on mangroves, such as fishing and gathering shellfish.
In addition to serving as food for other animals, the mouthless crab helps conserve the mangrove ecosystem, as it accelerates the decomposition of organic matter during feeding. A woman gathering mangrove clams.

A dense and tall canopy acts as a barrier, which protects against storms and hurricanes Filtration: Crabs must be maintained in a corral for at least crassum days and fed so as to complete a process of internal cleansing. A strong, above ground cadisoma system stabilizes the shoreline by reducing erosion by providing protection from waves and tides Protective barrier coasts: Then, the baseline is established using indirect methods, by which the number and status of burrows are verified to indirectly estimate the density, structure and biomass of the population.
Google Map link to region. The next morning, the cardisima crabs are checked and relevant information is recorded for each specimen size, sex, carapace color, if female has eggs and burrows size, texture prints. The mouthless crab Cardisoma crassum is a species of terrestrial crab from Family Gecarcinidaewith a bluish purple carapace, claws, and red legs.

The case study shows an ongoing pilot project that is generating positive results for the recovery of the mouthless crab. This process is accompanied by training and education of families that harvest the mouthless crab, and stresses the importance of sustainable management and enforcement of existing regulations.
The capture or harvest of the mouthless crab is an cardisoa artisanal activity, which generates income and serves as a food source for people in fishing communities that share these mangrove areas. Mangroves capture sediments and toxic substances contributing to water filtration before entering the ocean from the rivers Desalination: Mangroves are found within the intertidal fringes of tropical and subtropical coasts, as this is a transitional ecosystem between marine and coastal environments.
Ministerial Agreement of January 13, Fishing in the estuary.
Within the mangroves, there are transit easements and paths that have been traveled ancestrally. The goal is to see an increase in the number of active burrows.
In addition to their significant ecological role, mangrove habitats fulfill important economic, cultural, and social functions for the various communities settled on the banks of estuaries. The trap contains food bait to lure the crabs in. The scientific information available on the mouthless crab is very limited.
Crabs caught in the monitoring traps. Occurs during the crab growth period, when these crabs molt their carapace for a larger one.
The first results of this pilot project will be available Decemberwhich will be shared when available. Trap placed beside a burrow the evening before the monitoring day. It works as a catalyst and regenerator of wetland plant communities, especially in mangrove and tropical humid ecosystems. Similar situations exist with other species, such as crabs, in estuarine fisheries.
One month after repopulation, the second monitoring is performed by the indirect method with the same procedure as was used to collect baseline data. At present, she is President of the National Coordinating Corporation for the Defense of Mangrove Ecosystems, which is a network comprised of organizations of artisanal fishermen, gatherers and members of the Council of the International Mangrove Network.
