The map of marine activities supported by seagrasses at San Simón Bay highlights the areas with higher density of activities supported by seagrasses. This map helps to visualize the social benefits linked to seagrass ecosystem which supports the delivery of goods like cuttlefish or eels.
According to fishers, seagrass meadows favors eel, cuttlefish, sardine and recreational fishing. All interviewees recognize the importance of seagrasses in the maintenance of fisheries at San Simón Bay. In general they remark the role of these biological communities as refuge, habitat, nursery and spawning areas.
In the case of eels and cuttlefish fisheries, seagrasses are consider essential to their stock and long term survival. Concerning eel fishery, these phanerogams constitute the habitat for eels and the locations where fishers have catches. Moreover there is a cultural utility of these biological communities through the use of the fishing gears “butrones” which are left preferentially in zostera marina meadows as shelter areas. Leaving those gears in other locations out of seagrass meadows would make them to be exposured to the currents, increasing the risk of being silted.
For its part, there is a total consensus about the important role of seagrasses as spawning areas for cuttlefish and the role of this ecosystem in the production of cuttlefish. Regarding evidences, gatherers of shellfish by hand pointed they watch many cuttlefish spawns on seagrasses leaves during their harvesting jobs.
Gathering of shellfish has been considered also an activity favoured by seagrasses. Since interviewees recognise they find good seafood in low density patches, although about high density meadows answers are conflicting. Some are of the opinion that there is not seafood in those consolidated patches and others point they find good bivalves in them, especially gatherers of shellfish a float.
