Cryptic fish, species in preservation of reefs

The investigator in marine sciences and coastal, Juan Alfredo Zayas Alvarez, a study of the evolution of the ecosystem and diversity of cryptic fishes in artificial reefs, closed, in order to analyze community structure and their habitat selection.

The project also included the effect exerted by the depth on the variety and richness of cryptic fishes in the artificial reefs, in addition to identifying the energy flow of these species into the food chain.

Results showed that the depth is an important factor in these fish communities because at greater depths there is a greater richness of this species, said Zayas.

"We discovered that cryptic fish have no preference for any type of substrates such as rock, finger coral and shell nacre; "species such as the Scorpaenodes xyris just seek shelter where", noted. |

"We also identified that the cryptic fish community has a flow of important energy to higher trophic levels," said the graduate of the PhD in marine sciences and coastal of the Autonomous University of Baja California Sur (UABCS).

In an interview with the news agency of the National Council of science and technology, Zayas said that the majority of reef fishes have cryptic peculiarities, such as a reduced size, also can blend in with the environment at some stage in their life.

"These characteristics make it difficult to observe them and post them, hence the importance of studying these communities", said the specialist.

During the investigation, 36 modules that served were used as artificial reefs, each consisted of five boxes type Nestier with small holes, which allowed the young fish enter and take shelter.

Also, four series of nine modules, each one with a rock, concha nacar, fingers of coral and one without any substrate, were placed, as each one was divided and installed three, five and eight meters.

"These depths were selected because in the natural habitat, between one and three meters, in the area where we install the system there are many heads of coral, five meters thought it was going to be a transition zone, because eight meters only Rocky walls are", said Zayas.

"The depth creates a strong effect on the diversity and richness of species, which are an important part of the diet of other fish high in the food chain. To three meters had a wealth of nine species; five meters, 11, and eight meters, a wealth of 15 species", explained.

The specialist noted that the research can be applied in the restoration and conservation of habitats affected by overfishing and marine traffic, as well as the cultivation and marketing of fish for aquariums in a sustainable way.

"An important part of the research was to know what time of year you find more of these organisms and how many you can find, to have a better management of the population of these species. The goal was to have a control and capture natural without harming natural reefs", he stressed.
