VILLALOBOS-REYES, Salvador  and  GONZALEZ-PEREZ, Enrique. Determination of relative fish plant in tomato (Licopersicum sculentum L.) production in aquaponic system. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.5, pp.983-992. ISSN 2007-0934.

In the last decade, Mexico has taken aquaponics economic importance, but information on this production system is limited. Our aquaponics system was designed to determine the relationship fish-plant suitable for the production of tomato. In tanks with 450 L of water fingerlings they were seeded with initial individual weight of 0.45 g in three densities 120, 80 and 40 fish m-3. The fish were fed daily at a rate calculated on 7% of body weight per fish. The commercial feed 46% protein was used for a month and 28% protein for two months remaining. A total of 48 tomato seedlings were transplanted into three beds growth (16 plants per bed) 10 days after the stocking. Fish survival was 100%, feed conversion factor was 1.18 and the final weight per fish was 62 g. With the 20:1 ratio was obtained plants with average stem length of 160.6 cm, greater number of fruits (9) and average yield of 2.5 kg pta-1. The nutrient concentration in water was below the permitted limits, however, the low concentration of K and the absence of Fe and B affected the development of the plant after 90 days.
