Última Morphometrical development of tambaqui (Colossoma macropomum, Cuvier, 1818) under different photoperiods R. Bras. Zootec. Mendonça,Pedro Pierro; Vidal Junior,Manuel Vazquez; Polese,Marcelo Fanttini; Santos,Monique Virães Barbosa dos; Rezende,Fabrício Pereira; Andrade,Dalcio Ricardo de. The experiment was performed with 160 tambaqui (Colossoma macropomum) with average weight 11.01±2.08 g and total length 7.8±0.18 cm. Fishes were kept in sixteen aquariums with 56 L of water at 29.1±0.4 ºC of temperature, initial stocking density 1.97 g/L and constant aeration. The objective of this study was to assess the influence of photoperiod on fish performance. Treatments consisted of four photoperiods: T1 = 6 hours; T2 = 12 hours; T3 = 18 hours and T4 = 24 hours, with four replicates each. Fishes were fed twice a day with commercial extruded feed (28% of crude protein). The experiment was developed in closed circulation system, with volume of water renewal for each experimental unit equivalent to 40 times daily. Fish biometry was performed at the...

Cunha,Patrícia de Souza Lima; Lanna,Eduardo Arruda Teixeira; Bastos,Rafael Kopschitz Xavier; Quadros,Moisés; Rezende,Fabrício Pereira; Freitas,Leandro Monteiro de. The current study was aimed at investigating the use of different fertilizers - dicalcium phosphate, biosolid and quail feces - as a strategy for water fertilization in Daphnia sp production. It was used twenty-four 100-L tanks of asbestos cement distributed in a completely randomized split-plot design with six replicates, with plots in the three kinds of fertilizers (biosolid, dicalcium phosphate, and quail feces) and a control without fertilization (WF) and subplots at the times of assessment (days 8 and 13). It was assessed the biomass production of Daphnia sp. and the following water quality parameters: chlorophyll a, electrical conductivity, pH, dissolved oxygen, temperature, ammonia and organic nitrogen, total phosphorus and total hardness. There was... Tipo: Info:eu-repo/semantics/article Palavras-chave: Biosolids; Dicalcium phosphate; Plankton production; Quail feces.
