The module of tomato plants developed here using a substratum
of zeolite irrigated with a controlled system coupled to Pacific white shrimp may be considered intermediate in the context of technology and space requirements, between the traditional outfield soil culture and the hydroponics greenhouse systems. From this study on the integrated shrimp–tomato culture, it is possible to recognize the following advantages: (i) the reduced water use in comparison to traditional monocultures; (ii) the elimination of chemical fertilizers (nitrogen, phosphorus and other nutrients) for tomato plants; (iii) the decrease or elimination of the impact by shrimp effluent discharges; (iv) the possibility to obtain two products that normally do not occur in outfield culture; (v) the feasibility to increase the yield of both shrimp and tomato in comparison to the traditional practices of culture in outfield soil for tomato and in coastal farms for shrimp.
