Última Dynamics of some limnological characteristics in pacu (Piaractus mesopotamicus) culture tanks as function of handling BJB SIPAÚBA-TAVARES,L. H.; MORAES,M. A. G. de; BRAGA,F. M . de S.. In order to study the water quality in fish tanks, a 166-day (January to July 1992) experiment was realized using the indigenous species "pacu" (Piaractus mesopotamicus). Two different protein levels were tested in the diet (16% and 34% crude protein) and three stocking densities (0.25, 0.50 and 0.77 fish/m²). From the results, it was observed that the interactions between stocking density and experiment length affected the characteristics bicarbonate and alkalinity, as well as the interaction between stocking density and protein levels affected concentrations of free and total CO2, conductivity and pH (P < 0.05). The water temperature in tanks changed significantly during the period of study (P < 0.05),decreasing gradually from summer to winter....

Bras. Ciênc. Avic. Uğurlu,M; Akdağ,F; Teke,B; Salman,M. ABSTRACT This study was performed to investigate the effects of crude protein (CP) in diet and sex ratio on egg production, egg and hatching chick weight and hatchability traits in pheasants (Phasianus Colchicus). In this study, the treatment groups were constructed as 15% CP-5:1; 15% CP-7:1; 18% CP-5:1; 18% CP-7:1 for CP and sex (male:female) ratio respectively. The eggs were obtained from 48 weeks old pheasant. In this study, it was determined that there was positive effective on egg production, egg and hatching weight and hatchability of fertile eggs (HFE) for 18% CP. In contrast, fertility (FR) (p<0.05) and hatchability rate of total eggs (HR) (p>0.05), EPEM (p>0.05) and MPEM (p>0.05) tended to decrease with increasing CP. It was found that...
