In the Pacific coasts of Baja California, there are large submarine
prairies formed by brown seaweed that emerge from the sea covering extensions
of several hectares or square kilometers.
Macroalgae, seaweed, and live abalone in natural environment
These submarine prairies are characteristic of warm and cold waters just
like the ones of this coastal area of the country, and are known as Highly
Productive Ecosystems because a large variety of fishing resources live here,
such as abalone Haliotis spp., wavy turban snail Megastraea undosa, and lobster Panulirus spp., together with
other algal species as Gelidium robustum.
The presence of these resources has been the economic origin and
development of the fishermen who live in this region. The importance of these
highly productive systems has motivated the study of distribution and abundance
of the different species that live in them and the environmental factors that
Flora and fauna collection in rocky reefs
The goal of this project is to evaluate in what measure availability
and exploitation of macroalgae and seaweeds have an influence in the production variety of coastal marine resources in the Pacific region of Baja California Sur, on the part of the marine
animals associated to alga and seaweed.
Microalgae and seaweeds play an important role for the animals that
grow associated to them, because they are the main source of food for mollusks
or habitat for spawning and protection of mollusks, crustaceans, and fish, or
the substrate over which an enormous variety of benthic animals are attached.
The characterization of the algal communities of these environments and
their exploitation as food and/or habitat in these ecosystems turns out to be
fundamentally important to help us understand production and the regeneration
processes of the individuals that are extracted as product of fishery
activities. On the other hand, the information obtained will contribute to
analyze the good working order of the ecosystem (macroalgae and consumers) from
a global perspective of the system.
As a result of this project we have.
- Prepared a list of flora in the western coast of the Baja California Peninsula;
- Identified the macroalga banks with higher biomass and species richness;
- Identified and described the diet for the Giant Keyhole limpet M. crenulata.
