Inclusion of Elodea dense meal in ration of Clarias gariepinus

Abstract:

In aquaculture it is necessary to develop other feeding alternatives, as a consequence of the demand and high costs of nutrients. Therefore the objectives of this work were to determine the chemical composition of Elodea dense meal (HEd), and the biological response of African catfish (Clarias gariepinus) in its second stage of nursery, to include different percentages of the plant in the diet and the effect on water quality. The work was developed in the UEB "René Ramos Latour", Granma. Four rations were formulated with plant dust levels (0, 6, 12 and 18%). 240 organisms with an average weight of 1.28 ± 0.04 g were used; which were placed at a rate of 15 per replicate in each treatment, with a completely randomized design. The variables evaluated were the inci- dental and final weight, gain, consumption, height and food efficiency. A simple classification ANOVA was performed, a multiple comparison test was used. After 47 experimental days, significant differences were found (p <0.01) in the indicators studied, except for the first mentioned. The best results were obtained with inclusion 0 and 6. It was concluded that the vegetable is characterized by having a high percentage of protein and low fiber values, however its use as food decreased the biological indicators analyzed.
