14. Tempo de residÃncia da Ãgua em um sistema experimental de aquicultura integrada com camarÃes, ostras e macroalgas. / Residence time of water in an experimental integrated aquaculture with shrimp, oysters and seaweeds.
Shrimp culture presented at a world-wide level a significant growth in recent years, mainly in tropical and subtropical regions, however, this expansion comes with diverse environment negative impacts, mainly related to the cultures effluents, which are rich in nitrogen and phosphorous, that are many times discarded in the environment without any previous tr

15. 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

16. Digestibilidade aparente e verdadeira de proteína e aminoácidos em alimentos para tilápia do Nilo / Apparent and true digestibility of protein and amino acids in foods for Nile tilapia
The objective of this work was evaluate the apparent and true digestibility of the protein and of the amino acids of some foods by the techniques the decantation and dissection for Nile tilapia (Oreochromis niloticus) of the thailand line, in growth phase. Two trials were carried out, being the first led among the months of October to December of 2007 and th

17. MananoligossacarÃdeo durante a reversÃo sexual de tilÃpia do nilo / Mannanoligosaccharide during the sexual reversion for nile tilapia
This present study aimed to evaluate the use of prebiotic mannanoligosaccharide (Bio-MosÂ) during the sexual reversion to larvae of Nile tilapia. The study was realized in the Laboratory of Aquaculture of the Western Parana State University (Unioeste). Onethousand nd eighty larvae of Nile tilapia with three days old and initial average weight of 10.9 Â 1.2

18. Estratégia alimentar e densidade de estocagem para acarádisco (Symphysodon aequifasciata) / Feeding strategy and stocking density for discus fish (Symphysodon aequifasciata)
Four diets were tested to verify the effect of beef heart as feed enhancer for discus fish, studding the growth, weight gain, survivor, consumption, water quality and economic performance variables. Is was utilized 12 aquariums, distributed in 4 treatments and 3 replications. The treatments were: T1- 100% ration (42%PB); T2- 75% ration and 25% beef heart; T3

19. 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

22. Influence of artificial magnetic fields upon the behavior of the shrimp Litopenaeus vannamei (PENAEIDAE) and fish catch using fishtraps / InfluÃncia do campo magnÃtico artificial sobre o comportamento do camarÃo Litopenaeus Vannamei (PENAEIDAE) e a captura de peixes na pesca com covos
This work focuses on the behavior of marine organisms (fishes and shrimps) when submitted to artificial magnetic fields and on the use of this behavior as a mechanism to attract or to move away these organisms to/for specific areas. Although the geomagnetic field has existed in the planet a long time before of the beginning of the life rise little is known a

23. 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

24. Dinâmica de reprodução e comportamento reprodutivo de branchoneta Dendrocephalus brasiliensis Pesata, 1921 como incremento na produção de alimento vivo para peixes ornamentais
Reproductive behavior of Dendrocephalus brasiliensis Pesta, 1921(Crustacean: Anostracan). The reproductive behavior of fresh water Anostracan has been poorly investigated in carcinology specialized literature, specifically in relation to Dendrocephlaus brasiliensis Pesta, 1921, with abundant data just about the geographical distribution of that Anostracan.
