Elaboración de balanceado artesanal con harina de Gryllus Assimilis y de Moringa Oleifera para engorda del pez Andinoacara Rivulatus

Abstract

The substitution of traditional ingredients in the fish diet for new raw materials is a strategy aimed at improving the sustainability of aquaculture. This practice aims to reduce the environmental impact of the activity and promote fish welfare, presenting itself as a responsible and environmentally friendly alternative. The present work had the objective of elaborating a fish feed with 35% protein with the use of innovative raw materials in combination such as Gryllus assimilis meal and Moringa oleifera. Two feed diets were elaborated, named treatment B (100% elaborated feed), treatment AB (commercial feed and 50-50% elaborated feed), comparing it with treatment A (100% commercial feed) with a protein percentage of 35%. Four fish (Andinoacara rivulatus) were placed in each treatment and its replicate for a total of 36 fish during a period of 10 weeks. Data on weight and length were collected weekly, and temperature and pH values were recorded in the morning and afternoon, respectively. To evaluate and contrast the results, the SPSS statistical program was used, the data were processed with a non-parametric test, the Kruskall Wallis test was applied to compare the efficiency of the treatments with a significance level of 0.05. The results showed that the organisms obtained better weight and length with the AB treatment compared to the AB treatment. This showed that a 50% substitution of the commercial feed with Gryllus assimilis and Moringa oleifera meal is effective.
