With the objective of evaluating the effect of feeding rainbow trout (Oncorhynchus mykiss) with earthworms (Eisenia foetida) as whole food, on the productive and economic behavior of the rearing, the present investigation was carried out, with a total of 375 fingerlings, located in the César Vallejo sector, Agallpampa district, Otuzco province, La Libertad Region. The fish were distributed in 15 rectangular pools in which they received one of the three foods: Earthworm as the only food (AL), conventional feeding based on balanced food (AB) and mixed feeding (AB+AL), the mixed feeding was estimated so that each part contributes 50% of the dry matter required by the fish; the food supply was carried out for four months, with a feeding rate (in dry matter) of 5% of the biomass weight, divided into three times a day (8:0, 11:0, and 17:0 h). ; The supply of the worms was from a previously installed earthworm (Eisenia foetida) breeding, the balanced food (AB) used was of the trade name Truchina (Purina). The water supply to each pool was carried out through a 2““ polyethylene hose, coming from a natural source and through an open circulation system, the flow was regulated taking into account the water temperature, the oxygen concentration and the existing biomass in the tank. Earthworms (E. foetida), as the only food or mixed with balanced feed, generated similar weight gains, feed conversion and growth rate in rainbow trout (Oncorhynchus mykiss) to those fed balanced feed. It is concluded that feeding trout with earthworms generates greater economic benefits, influenced by the lower price of worms compared to comercial balanced feed.
