1. Eichhornia crassipes biomass as a dietary supplement for Pterophyllum scalare (Schultze, 1823)
ABSTRACT. Current study evaluates the macrophyte biomass of water hyacinth, Eichhornia crassipes, in diet food to improve the growth and survival of angelfish, Pterophyllum scalare. The liquid (extract) and ground modes are employed. Specific growth rate, weight gain, feed intake and final body weight in basal diet and macrophyte extract biomass diets were s

2. Neobenedenia melleni (Monogenea: Capsalidae) em peixes ornamentais de recife importados para o Brasil
Resumo Neobenedenia melleni é conhecido como um parasito letal para peixes teleósteos ornamentais marinhos capturados se não tratado. Este estudo relata a ocorrência de N. melleni parasitando quatro espécies de peixes ornamentais importados para o Brazil: Arabian angelfish (Pomacanthus asfur), yellowbar angelfish (Pomacanthus maculosus), regal angelfish

3. Description of growth and body composition of freshwater angelfish (Pterophyllum scalare) by Gompertz model
ABSTRACT The objective of this study was to describe the growth of freshwater angelfish (Pterophyllum scalare) using the Gompertz model, determining the relative growth and allometric coefficients of body components in relation to body weight and protein weight. Six hundred animals were grown until 233 days of age. Data on chemical composition (water, lipid,

4. Early ontogenesis of the angelfish, Pterophyllum scalare Schultze, 1823 (Cichlidae)
This study describes the egg membrane structures of angelfish (Pterophyllum scalare), morpho-physiological changes during angelfish embryogenesis from activation to hatching under optimal conditions (28°C; pH 6.8), the developing larvae and fry, the effect of alkaline pH on the early developmental stages of the species, the relationship between food item si

6. Feeding level and frequency for freshwater angelfish
The objective of this study was to determine the optimal feeding level and feeding frequency for the culture of freshwater angelfish (Pterophyllum scalare). A randomized block design in a factorial scheme (3 × 2) with three feeding levels (30, 60 and 90 g/kg of body weight (BW)/day) and two feeding frequencies (1x and 2x/day) was set up in duplicate, repres

7. Desempenho produtivo e tolerância térmica de juvenis de acará-bandeira (Pterophyllum scalare) alimentados com diferentes fontes de lipídeos / Productive performance and thermal tolerance of juvenile freshwater angelfish (Pterophyllum scalare) fed with different lipid sources
The present study was conducted to evaluate the influence of diets with different fatty acids composition, on the productive performance, as well as cold and heat tolerance of juvenile freshwater angelfish (Pterophyllum scalare). The experiment was accomplished in three phases. During phase one, the productive performance of freshwater angelfish was evaluate

8. Crude protein, digestible energy and stocking rate of ornamental acará-bandeira (Pterophyllum scalare) / Proteína bruta, energia digestível e densidade de estocagem do ciclídeo ornamental acará-bandeira (Pterophyllum scalare)
In order to increase the knowledge on the production of angelfish ornamental cichlids (Pterophyllum scalare), two experiments were conducted at the School of Veterinary Medicine and Zootecnia of the UFT, Araguaína /TO, between october 2008 and january 2009, using 400 angelfish juveniles. Each experiment had a duration of 42 days, with fish divided into 16 a

11. Polarity of some motility-related microtubules.
We have investigated the structural polarity of microtubules from several systems in which these fibers are thought to contribute to cell motility. By using a method for displaying microtubule polarity in the electron microscope, we find that both the A and B subfibers of Tetrahymena ciliary outer doublets and the inner pair of single microtubules are all or

12. Stripe formation in juvenile Pomacanthus explained by a generalized Turing mechanism with chemotaxis
Current interest in pattern formation can be traced to a seminal paper by Turing, who demonstrated that a system of reacting and diffusing chemicals, called morphogens, can interact so as to produce stable nonuniform concentration patterns in space. Recently, a Turing model has been suggested to explain the development of pigmentation patterns on species of
