GARZA-MARTINEZ, Miguel Ángel et al. Land suitability for growing tilapia (Oreochromis niloticus) with biofloc technology in the state of Durango, México. Ecosistemas y recur. agropecuarios [online]. 2021, vol.8, n.3, e3049.  Epub Oct 31, 2022. ISSN 2007-901X.  https://doi.org/10.19136/era.a8n3.3049.

Durango state has ideal environmental conditions to increase aquaculture development; however, in recent years the production of this activity has decreased and descended to the last places at the national level. One of the alternatives for a sustainable aquaculture development in the state is the application of Biofloc Technology (BFT) in production units of tilapia. The aim of this study was to determine the land suitability of the state for tilapia (Oreochromis niloticus) production with BFT. A multi-criteria evaluation was carried out by means of weighted sum with the support of a group of experts. An aptitude map for the activity was generated through Geographic Information System in which five categories of aptitude were established: very low, low, medium, high and very high. An area with high and very high aptitude of 50 182 km2 was estimated to develop the activity in the state, the regions with the highest aptitude were found in the central east and north of the state, mainly in the semi-arid zone. 39.67% of the high and very high aptitude estimated for the activity was concentrated in the municipalities with a Medium or Low Human Development Index (HDI), which represents an opportunity to increase food security in these municipalities. The results of this study will allow identifying suitable sites for implementing aquaculture projects in the state with an optimal approach in the use of water resources.

Keywords : Aquaculture management; food security; Geographic Information System; Human Development Index; water scarcity.
