Prior to the experiment, the fish were fed with the reference diet twice daily and for cachamma period of two weeks in order to accustom them to the experimental conditions.

Among test ingredients, the highest ADC drymatterADC protein and ADC energy were obtained for fermented macrophytes, whereas the significantly lowest value was displayed by the sundried macrophytes.

San Diego CA, U. Mississippi State University Extension Services. This value is close to those reported for other fish species and represents the first report of acute toxicity to the mercury in cachama cxchama.

Afterwards, seven experimental diets one reference diet and six test diets were randomly assigned to triplicate experimental groups. The experiment was conducted in a closed recirculation-system with constant aeration and a photoperiod of approximately 12 h of light. All diets were satisfactorily consumed, indicating that no palatability problem was encountered with any of the treatments during the experiment.

Food potential of aquatic macrophytes.

The lower ADC drymatter of bpanca aquatic macrophytes could be explained by their high mineral content ash content when compared to the fermented aquatic plants. Material and methods Sun Drying and Fermentation of Aquatic Plants The aquatic macrophytes used for experimental diets were harvested as cacuama or uncultivated plant material from water bodies in northern Colombia. The nutrient composition of the sundried and fermented material, as well as the diets and the faecal samples collected from each tank were determined in triplicates and performed following the AOAC procedures.

The presence of the stomach is an important feature bpanca a perspective of increased ability of fish to digest complex proteins and therefore to adapt to variable diets Grabner and Hofersince the gastric glands present in the stomach secret pepsin and hydrochloric acid with the purpose to contribute to the enzymatic degradation of foods in the stomach Kaye et al.

The apparent digestibility coefficients of dry matter ADC drymattercrude protein ADC protein and the gross energy ADC energy of the aquatic macrophytes Spirodela polyrhiza, Lemna minor and Azolla filiculoides treated by sun drying and lactic blana fermentation were determined for juveniles The apparent digestibility coefficients ADCs provide valuable information for the formulation of nutritional and economically feasible diets.

The proximate composition of the test ingredients, reference diet and test diets Table 1. Statistical Analysis In order to assess the separate and combined effect of the plant material three species and treatment sundried and fermentation on the dry matter, protein and energy digestibility in Cachama blanca a 3 x 2 factorial analysis of variances ANOVA was conducted.

Chemical Analysis The nutrient composition of the sundried and fermented material, as well as the diets and the faecal samples collected from each tank were determined in triplicates and performed following the AOAC procedures.

Fish, Acute Toxicity Test. Likewise, among test diets those containing fermented plants showed the lowest crude fibre and ash content, whereas protein and lipids contents were slightly higher compared to diets containing sundried macrophytes. Environmental Health Perspectives, The most obvious difference between diets containing fish meal and alternative plant ingredients is the lower available digestible energy content.
