The curimbata constitutes species of fish of wide distribution in the Neotropical area and high economic value. This work focused to evaluate processing yield and the chemical composition of the fillet in the male and female migratories and residents stocks of Prochilodus lineatus. The using the plotting was completely randomized by 4x2 factorial scheme, having as factors four stocks (one resident and three migratories) and two genders (male and female) with thirty replicates, considering each fish as an experimental unit. Each individual was submitted to the manual filleted and determination of the corporal composition (texts of moisture, crude protein, lipids, ashes and energy). They following parameters of yield had been evaluated (%): visceral entire fish (RPIE %); yield of boneless fillet (RFILE %) and processing yield of fillet with bone (RFILEC %). There was a significant difference (p<0.05) between the stocks and the studied samples. The biggest yield of boneless fillet were observed for the fish of the migrator stock I (45.77%). Males and females of the migrator stock I presented biggest fillet yield (46.79% and 43.93%, respectively), while the migrator III presented smaller yield (37.29% for males and 38.44% for females). The migratories stocks I, II and III presented values significantly smaller (p<0.05) of lipids level (0.98%; 2.01% and 1.97%, respectively) and an increase in the content of corporal protein in relation to the resident stock. It concluded that the male weighing 591g on average, belonging of the stock migrator I (captured in December), presented better thread yield and the stocks migratories are fish that has low fat tenor and high protein tenor.

The use of culture media produced with commercial fertilizers can represent a simple and low cost alternative for commercial orchid propagation. The aim of this study was to evaluate the in vitro growth of plantlets of Cattleya trianaei in culture medium MS reduced and and formulated with Peters® NPK 10-30-20 in different doses. 90 day-old plantlets with two leaflets were submitted to five treatments (T1 - reduced MS; T2 - Peters® 1 g L -1; T3 - Peters® 2 g L-1; T4 - Peters® 3 g L -1 and T5 - Peters® 5 g L-1) arranged in a completely randomized design with five replicates with 25 plantlets for each treatment and incubated during 180 days, with subcultures at each 60 days, when the number of roots, root length, number of leaves, shoot length and shoot fresh matter were evaluated. The simplified culture medium with fertilizer Peters® 3 g L -1 presented results statistically different as for the number of roots, number of leaves, shoot length and shoot fresh matter and it can be recommended for in vitro growth of this ornamental orchid.

Com este estudo objetivou-se avaliar o efeito do fotoperíodo sobre a composição centesimal de filés de juvenis de tilápia do Nilo. Utilizou-se um delineamento inteiramente casualizado com cinco tratamentos (0L:24E; 6L:18E; 12L:12E; 18L:6E; 24L:0E) e quatro repetições. Foram utilizados 160 alevinos de tilápia, distribuídos em 20 aquários (20L) em sistema de recirculação, temperatura controlada em 27 ºC e densidade de oito peixes por aquário. Os peixes foram alimentados duas vezes ao dia, com ração comercial extrusada contendo 40% de proteína bruta. Ao final de 75 dias, amostras do filé foram coletadas e armazenadas em freezer (-80 ºC) para posteriores análises da composição bromatológica. Não houve efeito dos diferentes fotoperíodos sobre a umidade e cinzas do filé (P>0,05). Por outro lado, os peixes sob fotoperíodo de 18L:6E apresentaram maior quantidade de proteína e retenção desta no filé, assim como menor quantidade de gordura e retenção de lipídeo (P<0,05). Portanto, pode-se concluir que o fotoperíodo pode alterar a composição corporal de alevinos de tilápia do Nilo, sendo que e o fotoperíodo de 18L:6E contribui para o aumento da concentração de proteína bruta e uma menor deposição de gordura no filé.
