dc.description.abstractAquaponics is the combination of aquaculture and hydroponic for the production of fish and plants, where thanks to a recirculation system, nitrifying bacteria convert the metabolic residues excribed by fish in nutrients irreplaceable for plants. Comparing with conventional aquaculture and hydroponic systems, the aquaponics system generates less environmental impact and uses much less water. However, the dependence of the aquaponics system on fish flour as fishmeal is noteworthy. Thereby, in this work, the larvae of Tenebrio molitor (TM) insect have been included in different proportions (0, 25 and 50%) in an aquaponics system formed by rainbow trout (Oncorhynchus mykiss) and lettuce (Lactuca sativa), in order to determine the capacity of TM to replace fish flour. To this end, the physico-chemical properties of water (temperature, pH, electrical conductivity and concentration of nitrogen compounds) and the growth of rainbow trout and lettuce in aquaponics systems fed with different diets, have been evaluated. Regarding water parameters, although some parameters exceed the optimal level, they have not influenced both the cultivation of trout and lettuce, since the system in general has remained in balance. It should be noted that in the tanks where the TM larvae have not been included, the growth of lettuce has been greater, but when the TM larvae have increased by 25%, a significant improvement has been observed in the cultivation of trout, thus confirming the capacity of the TM larvae to replace the feed based on fish flou.; Akuaponia akuikultura eta hidroponiaren konbinaketaren bidez arrainak zein landareak ekoizteko birzirkulazio-sistema bat da, non bakterio nitrifikatzaileek arrainek iraitzitako hondakin metabolikoak landareentzat ezinbertzekoak diren mantenugai bihurtzen dituzten. Akuikultura zein hidroponia sistema konbentzionalekin alderatuta, akuaponia sistemak ingurumen-inpaktu zein uraren erabilera murritzagoa aurkezten du. Hala eta guztiz ere, akuaponia sistemak arrain-irinarekiko daukan menpekotasuna nabarmentzekoa da. Hori dela eta, lan honetan, Tenebrio molitor (TM) intsektu espeziearen larbak arrainen dietan proportzio ezberdinetan gehitu dira (% 0, % 25 eta % 50), honek arrain-irina ordezkatzeko duen gaitasuna zehazteko ortzadar-amuarrainez (Oncorhynchus mykiss) eta letxugez (Lactuca sativa) osaturiko akuaponia sistema batean. Horretarako, dieta ezberdinekin elikaturiko akuaponia sistemetan uraren propietate fisiko-kimikoak (tenperatura, pHa, eroankortasun elektrikoa, eta nitrogeno konposatuen kontzentrazioa) eta ortzadar-amuarrainen zein letxugen hazkuntza ebaluatu dira. Uraren parametroei dagokienez, nahiz eta parametro batzuk maila optimoa gainditu, ez dute amuarrainen zein letxugen hazkuntzan eragin, sistema oro har orekan mantendu baita. Aipatzekoa da TM larbak gehitu ez diren tangetan letxugen hazkuntza handiagoa izan dela, baina TM larbak % 25ean gehitu direnean amuarrainen hazkuntzan hobekuntza nabarmen bat ikusi dela, eta horrela, egiaztatu da TM espeziearen larbek arrain-irinean oinarritutako pentsua ordezkatzeko duten ahalmena.
