Diel Variation in Abundance and Size of the South American Red Shrimp Pleoticus Muelleri (Spence Bate, 1888) (Decapoda, Solenoceridae) in the Ubatuba Region, Southeastern Brazil

Diel variation in the abundance and size of Pleoticus muelleri in the Ubatuba region was investigated during 2000. During each season of the year, sampling was conducted during the day and at night at 8 depths, from 5 to 40 m. The estimated number of shrimp was 955 individuals, 272 collected during the day and 683 at night. There was a difference in the abundance of P. muelleri between day and night (χ², p=2.33E-40). The abundance during the day and at night differed by season with the exception of the spring (χ², p=0.06). The abundance during both periods also differed by depth, except at 15 and 30 m, where it was not significant (χ², p=0.84 and 0.06, respectively). The shrimp caught at night were generally smaller than those caught during the day (Kolmogorov-Smirnov, p<0.01). Pleoticus muelleri juveniles were found primarily at night. This tendency could have influenced the lower mean size for this period. The sediment type and the bottom temperature appear to influence the behavior of this species and consequently the catch rate during the periods analyzed.

Effect of prey concentrations and feed training on production of Hoplias lacerdae juvenile

The aim of this work was to investigate the s of daily prey concentration during the first 15 days of active feeding of Hoplias lacerdae larvae, and the juvenile size on the feed training. In the first phase, the larvae received five Artemia nauplii concentrations (P). In the second phase, the juveniles from each treatment were trained to accept formulated diet. Superior growth was related to higher initial daily prey concentrations (900 and 1100 nauplii larvae-1). During feed training, the growth tendency was similar to that verified in the first phase. The lowest values of specific growth rate (SGR) were registered after the introduction of the semi-moist diet used in the feed training. However, the values of SGR recovered along the experiment and similar rates were found among the treatments. Survival, mortality and cannibalism were similar in the different treatments at the end of both phases. It can be concluded that: the prey concentration affects growth of H. lacerdae during the first 15 days of active feeding, and feed training can be initialized with juveniles of about 16 mm of total length.

Perfil hematológico de tilápias-do-nilo alimentadas com dietas contendo diferentes lipídeos e estimuladas por baixa temperatura

The goal of this paper was to determine the effects of seven diets with differents fatty acids sources in hematology of Nile tilapia before and after cold stimulus. Seven diets, with 3% of fatty acid source, were formulated: soybean oil (OS); fish oil (OP); beef tallow (SB) and mixtures of OS+OP; OS+SB; OP+SB e OS+OP+SB. Fish (112 male of Nile tilapia of 30,0 +/- 2,65g) were totally randomly distributed, with four replicates, into 28 plastic aquaria (40 L; 4 fish per aquarium). Fish were fed four times per day for 35 days. At 35th day and also after seven days cold stimulus blood was collected and the profile hematological was evaluated. Leucocytes numbers were reduced in fish fed a SB and fish oil combination diet and were highest in fish fed SB diet before cold stimulus. Plasma protein was reduced in fish fed soybean oil diets and highest in fishes fed a combination of soybean oil, fish oil and SB diets. Anything fatty acids source promotes effective changes in fish health and cold tolerance promotion. Cold don't drastically reduced fish general health status.

Resistência de porta-enxertos de cucurbitáceas a nematóides e compatibilidade da enxertia em melão

Nematodes severely attack net melon plants under protected cultivation conditions. The objective of this research was to select rootstocks with resistance to Meloidogyne incognita and M. javanica. The experiment was carried out under greenhouse conditions from October 2010 to April 2011 in Jaboticabal, Sao Paulo state, Brazil. Thirty-three cucurbitaceous genotypes were investigated as rootstocks; melons: CNPH 01-930 (Cucumis melo var. flexuosus), CNPH 01-962, 01-963 CNPH (Cucumis melo var. conomon), cvs. Gaucho Redondo, Gaucho Comprido, Redondo Amarelo, Gulfcoast, Chilton, Bonus no. 2, Fantasy; watermelons: cv. Charleston Gray, Progenie da Coreia (Citrullus lanatus); pumpkins: cvs. Mra. Ma, Ornamental, Howden, Mammoth, Kururu, Goianinha (Cucurbita moschata); gourd: Abobora de Porco, cvs. Maranhao, Brasileirinha (Lagenaria siceraria); squash: cv. Pataca Gigante (Cucurbita maxima); cucumber: cvs. Caipira, Branco Meio Comprido, Curumim (Cucumis sativus); loofah: Metro, Semente Branca, Semente Preta (Luffa cylindrica); wax gourd (Benincasa hispida); pumpkin rootstock: Hybrid cv. Keij; snake gourd (Trichosanthes cucumerins) and musk cucumber (Sicana odorifera). To evaluate the resistance, seedlings were transplanted to pots and the root inoculated with 3,000 eggs and second stage juveniles of M. incognita and M. javanica. Fifty days after the inoculation, the plants were evaluated for nematode resistance by means of the reproduction factor. The grafting compatibility between net melon cvs. Bonus no. 2 and Fantasy and the rootstocks previously characterized as resistant were evaluated by means of 60 graftings. CNPH 01-962, CNPH 01-963 and melon 'Gaucho Redondo', were considered resistant to M. incognita. Melon 'Redondo Amarelo', watermelon 'Charleston Gray', watermelon Progenie da Coreia, Trichosanthes cucumerins were considered resistant to M. javanica. Benincasa hispida was resistant to M. javanica and M. incognita. The compatibility between net melons and resistant rootstocks was higher than 98%.

Histologia do fígado de tilápia do Nilo (Oreochromis niloticus) alimentados com dietas contendo silagem biológica de pescado

This study aimed to evaluate possible histopathological liver of tilapia fed diets containing fish silage and level protein. Sample of 180 fed with tilapia fingerlings fed with diets containing three protein levels (20, 24 and 28% CP), and Proportions residue fermented silage of tilapia (1/4 and 1/2) of were analyzed during 75 days. The tissue fragments were fixed in Bouin and included in Histosec (R). After that, between 2 to 5 mu m slices were done in a rotation microtome. The methods used for tissue analysis were hematoxilin/eosin and PAS. The histological slices were examined under light microscope (Olympus BX-50). The disarray in the morphology of the liver of fish fed biological silage was influenced by high protein levels, and increased proportions of 1/2 of animal protein diets. It was observed that the variation of hepatocytes is directly related to the type of diet for fish. In fish fed diets containing 28% CP, the liver showed disruption of the structure cordon of hepatocytes, necrosis and shifting points of the core to the periphery. Elevated levels of biological fish silage cause deleterious changes in the liver. The level of protein required to maintain the health of the associated development fish is 24% crude protein.

Linguagens documentais para as bibliotecas escolares: o caso da Espanha, Portugal e Brasil

This article analyzes the specific features and processes of indexing and classification performed in school libraries to process and retrieve information from their collections. Subject languages used in Spanish, Portuguese and Brazilian Portuguese school libraries are also analyzed. To achieve this goal, the concept of school library was analyzed, its function was studied and the techniques and tools that allow the information organization were examined. Among the tools, we studied the Subject Headings Lists for children and juveniles'books and the Subject Headings List for public libraries, the Universal Decimal Classification System (paperback edition) or the classification by fields of interest and specialized thesauri like the Tesauro de la Educacion UNESCO-OIE and the TesauroEuropeo de la Educacion.
