Pirarucu (Arapaima gigas) is an obligatory air-breathing fish from the Amazon basin. Previous study showed that pirarucu juveniles present a latency period in their response to moderate stress (transportation). Therefore the objective of this study was to verify the effects of a prolonged air exposure stress in lactate, glucose, cortisol, haematocrit, haemoglobin, and liver glycogen in pirarucu. Thirty-six fish were handled by netting and subjected to air exposure for 75-min. Six fish were sampled before handling and at 0, 6, 24, 48, and 96h after handling. Fish cortisol, lactate and haematocrit rose after handling, returning to previous unstressed values on the following sampling (6h after handling). Glucose increased significantly after handling and that...

Fish transport is one of the most stressful procedures in aquaculture facilities. The present work evaluated the stress response of matrinxã to transportation procedures, and the use of clove oil as an alternative to reduce the stress response to transport in matrinxã (Brycon cephalus). Clove oil solutions were tested in concentrations of 0, 1, 5 and 10 mg/L during matrinxã transportation in plastic bags, supplied with water and oxygen as the usual field procedures in Brazil. Clove oil reduced some of the physiological stress responses (plasma cortisol, glucose and ions) that we measured. The high energetic cost to matrinxã cope with the transport stress was clear by the decrease of liver glycogen after transport. Our results suggest that clove oil (5...

Stressed plants are generally more attacked by galling insects. In this study we investigated the relationship between population abundance and species richness of galling insects on the tree Alchornea castaneaefolia A. JUSS. (Euphorbiaceae), submited to stress induced by the hemiparasite Psittacanthus sp. (Loranthaceae) in the Amazon, Brazil. Branches of A. castaneaefolia attacked by the hemiparasite were more heavily infested by galling insects than non-attacked branches. The field observations partially corroborate the hypothesis that there would be an optimal level of host-plant stress for galling insect establishment.

This study examined the stress response of pirarucu juveniles in a closed system transport. Pirarucu (Arapaima gigas) is a native Amazonian fish species from the Osteoglossidae family and an obligated air breather. A short duration transport trial (6h) was undertaken comparing closed polyethylene bags filled with atmospheric air (Air group) and bags filled with pure oxygen (Oxi group). Dissolved oxygen was the only water parameter that presented a difference between fish groups, and was saturated in the oxi group as expected. There was no mortality in either group after transport. Fish feeding was observed 36 h after transport for all fish, and normal feeding consumption was observed at 72 h. In both groups physiological responses were similar. Cortisol...

The role of vitamin C on physiological responses of matrinxã (Brycon amazonicus) submitted to air exposure was analyzed. Nine hundred fish (70.15 g) were distributed in fifteen 500 l boxes (60 fish.box-1) and fed five rations (treatments): Control (no vitamin C); T100 (100 mg); T200 (200 mg); T400 (400 mg) and T800 (800 mg of vitamin C kg.ration-1). Each ration was offered to fish of three boxes during 60 days before the stress challenge that consisted of exposing fish to air for two minutes. Samplings were carried out for 5, 15, 30 and 60 minutes after the air exposure. Blood was collected for glucose, cortisol, total protein, sodium, chloride, hematocrit, hemoglobin determination, and white and red cell count. Liver was removed for hepatosomatic index...

The present work evaluated several aspects of the generalized stress response [endocrine (cortisol), metabolic (glucose), hematologic (hematocrit and hemoglobin) and cellular (HSP70)] in the Amazonian warm-water fish matrinxã (Brycon amazonicus ) subjected to an acute cold shock. This species farming has been done in South America, and growth and feed conversion rates have been interesting. However, in subtropical areas of Brazil, where the water temperature can rapidly change, high rates of matrinxã mortality have been associated with abrupt decrease in the water temperature. Thus, we subjected matrinxã to a sudden cold shock by transferring the fish directly to tanks in which the water temperature was 10ºC below the initial conditions (cold shock from...

The interspecific hybrid, Elaeis oleifera x Elaeis guineensis (OxG) is an alternative for improving the competitiveness and sustainability of the Latin American oil palm agro-industry, because of its partial resistance to some lethal diseases and also because of the high quality of its oil. A comparative characterization was conducted of the physiological and biochemical performance of seedlings of six OxG hybrids grown in hydroponics. Gas exchange, vegetative growth, protein, sugar and photosynthetic pigment content, and antioxidant system activity were determined. With the exception of gas exchange, the other variables showed significant differences between materials. The ´U1273´ and ´U1737´ materials showed greater vegetative growth with no expression...

Metabolic responses and β-carotene production by the unicellular green alga Dunaliella salina exposed to leaf extracts

Einali,Alireza; Mazang-Ghasemi,Sahar; Valizadeh,Jafar; Noorozifar,Meisam.

ABSTRACT The present work investigated the effects of aqueous extracts of eucalyptus ( Eucalyptus globulus) and elderberry ( Sambucus ebulus) leaves on β-carotene productivity in Dunaliella salina, a green microalga. Leaf extracts from eucalyptus have greater amounts of phenolics and flavonoids, as well as greater ferric reducing antioxidant potential than elderberry. The extracts of both species greatly inhibited growth of algal suspensions. However, chlorophyll and β-carotene concentration increased in cells treated with leaf extracts, and the highest values were detected in 1 % eucalyptus and 2 % elderberry extracts. Fresh weight, total sugar, and protein content significantly increased following exposure of cells to different doses of leaf extracts....

We tested the preference prediction of plant vigor hypothesis by examining the relationship between gall occurrence and leaf size. We also examined the effect of galls on leaf asymmetry, which is a measure of developmental instability. Gall occurrence did not increase with leaf size, thereby providing no support to the preference prediction. Galled leaves were significantly more asymmetric than ungalled leaves. Moreover, leaf asymmetry increased with both gall occurrence and gall size, indicating that galls boosted the stress levels in Ouratea polygyna.

The effects of seasonal change of water level in an estuary on Ludwigia octovalvis (Jacq.) P. H. Raven (Onograceae) growth

Ribeiro,Jose Pedro Nepomuceno; Matsumoto,Reginaldo Sadao; Lima,Maria Inês Salgueiro.

The Massaguaçu River estuary is an irregular estuary with sandbar breaching cycles that are irregular and happen several times each year. The species Ludwigia octovalvis is a perennial weed in several places around the world, but it is seasonal in the Massaguaçu River. In this survey we determined the relationship between the rain, estuary water level variation, and the spatial and temporal distribution of this species. In a laboratory we simulated the water level variation in water tanks in order to understand how this species responds to flooding. In the field, we determined the distribution of L. octovalvis in the higher pluviose season and in the lower pluviose season. This species is relatively common in the higher pluviose season and completely...

The behavior of 15 Girolando cows from three genetic groups (1/2, 5/8 and 3/4 HG) in feedlots was evaluated. Experimental design was completely randomized with 3 treatment (genetic groups) and 5 replicates. The animals were evaluated by the variables: food, rumination, rest, locomotion, water intake, demand and time in the shade, and other activities. Group 5/8 HG spent more time feeding (267.88 min.) than groups 3/4 HG (245.55 min.) and 1/2 HG (259.55 min.). Idle standing time was higher (204.66 min.) for 3/4 HG when compared to the other groups. There was no statistical difference for the duration of rest in the shade. Solar radiation and THI were the factors which most influenced the animals’ behavior. Results show that the genetic groups 5/8 and 3/4 HG...

In 2014, Brazil produced 474.33 thousand tons of captive-bred fish. In addition, regulatory agencies of animal ethics and welfare have recently encouraged experiments to be done using simpler vertebrates, such as fish. The aim of this article was to perform a scientometric analysis of scientific production that deals with fish welfare, in an attempt to find trends and gaps in this line of research. Our analyses showed a growing concern about fish welfare, although several questions remained inadequately covered. The most studied species was the Atlantic salmon, with Norway having the most publications on this theme. There are controversies among scientists about fish capacity for suffering and enjoyment (sentience). As regards slaughter or euthanasia,...
