The mugílidos, more specifically the smooth ones, are species of interest for the aquaculture, an interest that comes determined by its omnivorous profile in early stages of growth and a tendency to herbivores from the 60-70 days of development, its fast growth and its resistance to environmental variations that makes it possible to cultivate in fresh, slightly brackish or marine water.
This fact makes them excellent candidates for the diversification of the species that are currently cultivated.
For this reason, researchers from the University of Murcia (UMU) and the University of Cádiz (UCA) together with the Zaporito Integrated Maritime Professional Training Center, have carried out a project with the aim of obtaining a specific diet for this species , paying special attention to by-products of the agri-food sector.
In the framework of this study, entitled "Design and evaluation of diets for a sustainable aquaculture of mugílidos - MUGILDIET" the work of Ángeles Esteban, principal investigator of the research group Immunity System Inespecífico of Fishes Teleósteos of the University of Murcia, focuses on the well-being of the crops, their immunological state and in increasing the knowledge about this species on which there are few works in this field.
María Ángeles Esteban believes that "the mugílidos are one of the most attractive candidates for the diversification of aquaculture, so the results of this project can help any company dedicated to this field be encouraged to grow these species."
"We hope that the capture of fingerlings will stop or disappear, since captive breeding has been achieved with success rates similar to those of other cultivated marine species," says Esteban Abad, an expert in Cell Biology and Histology.
From the UCA, they affirm that "nowadays one of the limiting factors for the increase of the production of mullets is the inexistence of commercial diets adapted to the species and its nutritional requirements".
And is that as has happened before with other species of aquaculture such as sea bream or sea bass, it is essential to advance in the improvements in knowledge of nutrition.
"This step is linked to the circular economy and the valorization of by-products from other industries, which will be possible to a large extent thanks to the involvement of the University of Cádiz," the same sources confirm.
During the execution of this work, it is expected to carry out different workshops aimed at professionals of the sector as well as the general public.
In these meetings you can discuss the cultivation and nutrition of the species, the environmental importance of the sustainable use of water and natural areas by sustainable aquaculture, understood as such compatible with other activities such as salt or conservation of our coasts.
For its part, and in charge of the zootechnical evaluation of the crops, there is the Vocational Training Institute Zaporito, dependent on the Ministry of Education of the Junta de Andalucía.
In addition, the project has the involvement of Biothesan and the Andalusian Aquaculture Technology Center (CTAQUA).
This project, coordinated by Juan Miguel Mancera, professor of Zoology at the University of Cádiz, has the support of the Biodiversity Foundation of the Ministry of Agriculture and Fisheries, Food and Environment, through the Pleamar Program of the FEMP.
