1. Evaluation of a rapid detection method of Salmonella in comparison with the culture method and microbiological quality in fish from the Brazilian Amazon
Abstract Microbiological safety of fish is a concern of consumers, industries and regulatory agencies worldwide. Among the pathogenic microorganisms, Salmonella spp. is one of the main agents of foodborne diseases and should be absent in animal products. Rapid and accurate identification of pathogens in the supply chain is important for both quality assuranc

2. SOIL COMPACTION AND THE STABILITY OF LEVEES OF AQUACULTURE PONDS
ABSTRACT The aim of this work was to evaluate the effects of variations in soil compaction on the stability of the slope embankments of fish farms used in aquaculture. Computational modeling was performed using the RocScience Slide 6.0 program, simulating filling scenarios, fast lowering and stationary regimes for the full operation of the fish farms. The da

3. Cytoarchitecture of the superior olivary complex of three neotropical species of bats (Noctilio leporinus, Phyllostomus hastatus and Carollia perspicillata) with different foraging behavior
Resumo O entendimento da ecolocalização pelo estudo de diferentes núcleos auditivos de morcegos pode ser um elo importante na elucidação das inúmeras questões que surgem em relação ao seu comportamento de forrageamento. O complexo olivar superior (SOC) é o principal centro de processamento das pistas binaurais usadas na localização do som, já qu

4. Development and application of a flexible numerical model to evaluate the safety of room-and-pillar mines
Abstract The design of room-and-pillar mines relies on the correct estimation of the safety indicator of the underground structures formed by the excavation of drifts. Thus, the study of the geomechanical behavior is of vital importance. The mathematical models play an important role in the identification of problematic areas and allows different configurati

5. Fish habitat associations along a longitudinal gradient in a preserved coastal Atlantic stream, Brazil
ABSTRACT Habitat conditions at multiple scales are one of the major factors structuring ichthyofauna. Thus, we analyzed the fish habitat associations along the headwater-mouth gradient of a coastal Atlantic stream. We categorized the sampling sites into habitat units, so that in the middle reach these categories were statistically differentiated into riffles

6. A protocol for measuring spatial variables in soft-sediment tide pools
ABSTRACT We present a protocol for measuring spatial variables in large (>50 m2) soft-sediment tide pool. Secondarily, we present the fish capture efficiency of a sampling protocol that based on such spatial variables to calculate relative abundances. The area of the pool is estimated by summing areas of basic geometric forms; the depth, by taken representat

7. Characterization of α-actin isoforms in white and red skeletal muscle types of Leporinus macrocephalus (Characiformes, Anostomidae)
ABSTRACT Two α-actin genes of the fish Leporinus macrocephalus, referring to white and red muscle tissues, were isolated. Actin isoforms, that mainly differed by a Ser/Ala155 substitution, can have a functional significance related to actin-ATP interaction. An Ala155 residue, as observed in the α-skeletal actin from red muscle, results in a decrease in act

8. Idade, crescimento e biologia reprodutiva da Raia-viola Rhinobatos percellens (Walbaum, 1792) capturada pelo arrasto de praia em Caiçara do Norte/RN.
Caiçara do Norte (05 04S and 36 03W) is considered one of the biggest marine fish producer in the Rio Grande do Norte State where beach seine captures shrimp. Rhinobatos percellens is the third most abundant species found in the by-catch. From June 2003 to May 2011, 714 beach seine hauls were closely monitored with the objective of analyzing the population

9. Desenvolvimento de um sistema de recirculação com uso de wetlands construídas para efluentes da piscicultura / Development of a recirculating system using constructed wetlands for aquaculture effluents
Global aquaculture has been growing very fast in recent decades due to several factors, including: population growth, demand for low calorie protein and especially the reduction of natural fish stocks. Brazil has enormous potential to become a world leader in fisheries production in captivity. However, the development of aquaculture in Brazil must be conduct

10. Toxicidade da deltametrina (formulação Butox CE25) nas respostas cardio-respiratórias da tilápia-do-Nilo (Oreochromis niloticus)
Deltamethrin is a synthetic pyrethroid pesticide, type II, considered of low persistence in the environment and widely utilized in agriculture and aquaculture to control plagues and aquatic parasites respectivamently. In spite of it low toxicity in mammals, this pesticide can be extremely toxic for fish. In this study, we evaluate the effects of a sub-lethal

11. Crescimento, hematologia e metabolismo de pacu (Piaractus mesopotamicus) submetido ao exercício aeróbico e alimentado com níveis crescentes de proteínas
The composition of the diet, the metabolic adaptations and variations in the activity of the fish are the main factors responsible for seasonal changes in physiological variables. It is known that aerobic exercise can improve the fish growth due to: the enhancement of feed conversion, reduced dominance, increased protein synthesis and lipid and glucose catab

12. Efficacy of clove oil as anesthetic in handling and transportation of Nile tilapia, Oreochromis niloticus (Actinopterygii: Cichlidae) juveniles
This work evaluated the efficiency of clove oil as anaesthetic in handling and transportation of Nile tilapia, Oreochromis niloticus (Linnaeus, 1758). In the first experiment, safety concentrations of clove oil were assessed by measuring induction times to anaesthesia. The second experiment evaluated exposure times to anaesthetic. Clove oil efficiency during
