13. Weight and morphometric growth of different strains of tilapia (Oreochromis sp)
The objective of this study was to evaluate the morphometric growth and weight gain of strains of tilapia (Thai, Red, UFLA and Commercial) by nonlinear models. Initially, 500 male fingerlings of each strain, at 85 (Red and UFLA) and 86 (Thai and Commercial) days of age, were stocked separately in raceways with 56 m³. Twenty fish of each strain were randomly

14. Performance and isotopic composition of 13C and 15N in muscle tissue of Nile tilapia (Oreochromis niloticus) fed with different protein / Desempenho produtivo e composição isotópica de 13C e 15N no tecido muscular de tilápia do Nilo (Oreochromis niloticus) alimentada com diferentes fontes protéicas
Alternative sources of food have been studied in substitution for fishmeal in aquaculture, and it may result in a difference in incorporation of carbon and nitrogen, depending on the nutritional value and availability of the source. Two experiments were designed to quantify the participation of different protein sources in the muscle tissue in juvenile and p

15. Digestible lysine requirement of Nile tilapia fingerlings fed arginine-tolysine-balanced diets
This study was conducted to determine the digestible lysine requirements of Nile tilapia fingerlings. Fish (n = 300; average initial weight = 1.44 g) were distributed 15 300-L aquariums, in a completely randomized design with five treatments and three replicates, and fed extruded diets containing 11.3, 13.7, 16.1, 18.4 or 20.8 g/kg of digestible lysine. The

16. Performance and stress resistance of Nile tilapias fed different crude protein levels
The objective of this study was to evaluate the effect of different levels of diet crude protein on the performance and stress resistance rate (Re) of Oreochromis niloticus larvae and fingerlings. In the first experiment, 5, 15 and 25 day-old animals were submitted to 1, 5, 7, 10, 15, 20, 30 and 40 minutes of air exposure on a sieve. In the second experiment

17. AvaliaÃÃo da Piscicultura em Esgoto DomÃstico Tratado: Aspectos ZootÃcnicos, Ambientais e de Qualidade do Pescado Produzido / Evaluation of treated domestic sewage in fish: aspects of husbandry, environmental and quality of fish produced.
The use of wastewater is an alternative widespread nowadays. One way to reuse it in fish activity, considering that the effluent from Sewage Treatment Stations, are rich sources of nutrients that could be used by fish. However, some restrictions arise regarding the quality of animals for use in human diet. Thus, this research was conducted using treated sewa

19. Cultivo de cachama blanca en altas densidades y en dos sistemas cerrados
The objective of this work was to evaluate the tolerance of red-bellied pacu, Piaractus brachypomus, to high-density in closed production systems. Nine hundred fingerlings with 44.3±26 g weight were distributed in six 4.8 m³ concrete tanks. Three tanks had zero water exchange rate (SCR), and in the other three water was connected to a bioclarifier (SRA). A

20. Morphologic analysis of developmental phases and gill ontogenesis in neotropical species Poecilia vivipara (Cyprinodontiformes: Poeciliidae) exposed to different salinities
The present study evaluated and characterized the different phases of development and the cell types present in the gill epithelium of embryos, larvae, and fingerlings of guppy (Poecilia vivipara Bloch & Schneider, 1801) specimens exposed to water with salinity ranging from 0‰ to 20‰. The development of P. vivipara was classified into eight phases. The y

21. Genetic diversity of piracanjuba used in stock enhancement programs with microsatellite markers
The objective of this work was to estimate the genetic diversity of a Brycon orbignyanus lot used in stock enhancement programs, using microsatellite markers. Samples of 44 broodstocks, 70 larvae and 69 fingerlings, were analyzed with amplification of five loci described for Brycon opalinus. The number of alleles, the observed (Ho) and expected (He) heterozy

22. Levels of protein and energy in diets for fingerlings of trairão Hoplias lacerdae / Níveis de proteína e energia em dietas para alevinos de trairão Hoplias lacerdae
Through the present research work, evaluating the levels of crude protein (CP) and gross energy (GE) for fingerlings of trairão (Hoplias lacerdae) was sought. The completely randomized design with four replicates in factorial scheme 4 x 3 were utilized, namely, four levels of crude protein (35; 39; 43 and 47%) and three levels of gross energy (4100; 4300 an

24. Manejo durante o condicionamento alimentar de alevinos de trairão (Hoplias lacerdae) / Management at feed training of trairão fingerlings (Hoplias lacerdae)
The aim of the present work is to evaluate the stocking density and the transition time among the used diets in feed training process of trairão Hoplias lacerdae fingerlings. We made an experiment with full factorial delineation which had five stocking densities (4, 6, 7, 8 and 10 fish/L) and four transition time among diets (2, 3, 4 and 5 days). Trairão f
