Provedor de dados: 5
Autores: Richard, Marion; Maurice, Julien-thomas; Anginot, Aurore; Paticat, Francois; Verdegem, M. C. J.; Hussenot, Jerome.
The main objectives of this investigation were to test the effects of (i) the presence of periphyton substrates, (ii) rearing density and (iii) supplemental feeding with dry feed on the growth and production of golden mullet (Liza aurata) juveniles. Twenty-six 1 m(2)-cages were installed in a French marine pond from April till June 2008. Mullets were stocked in cages with or without substrate at a density of 0, 20,40 or 60 individuals per cage. Each treatment was carried out in triplicate. In addition, 20 fish were put in three tanks and fed ad libitum with dry feed. The results showed that (i) although mullets were seen to graze on periphyton substrates, their presence did not affect,mullet growth and production. In future studies, meshed substrates could...

A comparative study of Ligophorus uruguayense and L. saladensis (Monogenea: Ancyrocephalidae) from Mugil liza (Teleostei: Mugilidae) in southern Brazil
Provedor de dados: 5
Autores: Marchiori, Natalia C.; Pariselle, Antoine; Pereira, Joaber, Jr.; Agnese, Jean-francois; Durand, Jean-dominique; Vanhove, Maarten P. M.
Representatives of Ligophorus Euzet et Suriano, 1977 were found on the gills of Mugil liza Valenciennes caught in southern Brazil. They were identified as Ligophorus uruguayense Failla Siquier et Ostrowski de Nufiez, 2009 and Ligophorus saladensis Marcotegui et Martorelli, 2009, even though specific identification proved to be difficult due to inconsistencies in some diagnostic features reported for these two species. Therefore, a combined morphological and molecular approach was used to critically review the validity of these species, by means of phase contrast and confocal fluorescence microscopical examination of sclerotised hard parts, and assessing the genetic divergence between L. saladensis, L. uruguayense and their congeners using rDNA sequences....

Karyotype characterization of Mugil incilis Hancock, 1830 (Mugiliformes: Mugilidae), including a description of an unusual co-localization of major and minor ribosomal genes in the family
Provedor de dados: 83
Autores: Hett,Anne Kathrin; Nirchio,Mauro; Oliveira,Claudio; Siccha,Zoila Raquel; Rossi,Anna Rita; Sola,Luciana.
This study reports the description of the karyotype of Mugil incilis from Venezuela. The chromosome complement is composed of 48 acrocentric chromosomes, which uniformly decrease in size. Therefore, the homologues can not be clearly identified, with the exception of one of the largest chromosome pairs, classified as number 1, whose homologues may show a subcentromeric secondary constriction, and of chromosome pair number 24, which is considerably smaller than the others. C-banding showed heterochromatic blocks at the centromeric/pericentromeric regions of all chromosomes, which were more conspicuous on chromosomes 1, given the C-positive signals include the secondary constrictions. AgNO3 and fluorescent in situ hybridization (FISH) with 45S rDNA...

The ultrastructure of the mullet Mugil curema Valenciennes (Teleostei, Mugilidae) spermatozoa
Provedor de dados: 104
Autores: Eiras-Stofella,Daura Regina; Gremski,Waldemiro; Kuligowski,Sandra Maria.
The structure of the spermatozoon of Mugil curema Valenciennes, 1836 was studied using scanning and transmission electron microscopy. The spermatic head is rounded and formed by the nucleus containing granular chromatin, firmly packed resulting in a mass extremely electron dense. The acrossome is absent. The midpiece is characterized by the presence of two centrioles, a plasmatic canal, very few vesicles, and several mitochondria (9-10) with aproximately 0.50µm in diameter. The head and the midpiece are aproximately 1.56µm in diameter. The flagellum conforms to the 9 + 0 flagellar pattern near the transition region in its midpiece and is 9 + 2 from there on up to the distal region of the axoneme. The electron density in the A tubules 1, 2, 5 and 6 shows...

Distribuição e abundância de tainhas e paratis (Osteichthyes, Mugilidae) na Baía de Sepetiba, Rio de Janeiro, Brasil
Provedor de dados: 104
Autores: Silva,Márcio de Araújo; Araújo,Francisco Gerson de.
Variations in the físh populations of mullets were assessed aiming to detect trends in abundances during their early life cycle and relationship with environmental parameters. Fish were sampled between August 1994 and July 1997 using a beach scine and environmental parameters of water temperature, salinity and transparency were taken at each sampling. Five sites were systematically sampled, two of them in the inner Bay, and three in the outer Bay near to the sea limit. Three Mugilidae species were identified: Mugil liza Valencienes, 1836; Mugil curema Valencienes, 1836 and Mugil platanus Günter, 1880; mostly juveniles in their early life cycle, being M. liza the most abundant species. Overall all mullets were more abundant in the inner Bay, where...

Haematological characteristics of freshwater-reared and wild mullet, Mugil platanus Günther (Osteichthyes, Mugilidae)
Provedor de dados: 104
Autores: Ranzani-Paiva,Maria José T; Ishikawa,Carlos M.
Mullets, Mugilplalanus Günther, 1880. were obtained from the estua-rine area of CananÉia (São Paulo, Brazil) and from freshwater tearing tanks. For each fish the body weight, body length, gonad weight and gonad maturation stage were recorded and the allometric index (K) was calculated. Blood was collected for hematocrit (Ht), hemoglobin level (lib), total cell count (Er), and the determination of hematological indices (MCV. MCH, MCHC), as well as the differential leukocyte count (lymphocytes, monocytes, neutrophils, basophils and '"other cells"). The averages of the hematological analyses, hematological indeces, condition factor and leukocytes percentage of the specimens acclimated to fresh water were significantly higher than those of the specimens from...

Provedor de dados: 104
Autores: Ranzani-Paiva,María José Tavares; Ishikawa,Carlos Massatoshi; Campos,Benedicto do Espírito-Santo de; Eiras,Augusta Cocuzza das.
This study involved 344 Mullets, Mugil platanus Günther, 1880, captured in the estuarine region of Cananeia, São Paulo, Brazil (25º00'S, 47º55'W). The following data were recorded for each fish: total weight, total length, haemoglobin ratio (Hb), haematocrit (Ht), erythrocyte count (Er), differential leucocyte count (lymphocytes, monocytes, neutrophils, basophils and "other cells") and haematometric indices; MCV, MCH, and MCHC. The sex and stage of gonadal maturity (undifferentiated, juvenile, resting, maturing, mature, and spent) were determined by macroscopical inspection of the gonads. Parasitological inspections revealed the following infestations: Gills - Trichodinidae, Monogenea, Copepoda, and Hirudinea. Liver: cysts of Digenea. Intestine: Nematoda,...

Exogenous enzyme complex prevents intestinal soybean meal-induced enteritis in Mugil liza (Valenciennes, 1836) juvenile.
Provedor de dados: 42
Autores: RAMOS,LEONARDO R.V.; PEDROSA,VIRGÍNIA F.; MORI,AGNES; ANDRADE,CARLOS F.F. DE; ROMANO,LUIS A.; ABREU,PAULO C.; TESSER,MARCELO B.
ABSTRACT Four soybean meal-based diets containing increasing levels of an enzyme complex (E50, E100, E150 and E200 at 50, 100, 150 and 200 g ton-1, respectively) and one soybean meal-based diet without the enzyme complex (E0) were fed in triplicate to M. liza juveniles in a semi-static flow system with 20 fish per tank for 75 days. There were no differences between the treatments for animal performance parameters, but fish fed the enzyme complex treatment exhibited significantly (P&lt;0.05) higher values of calcium bone retention compared with control fish. Although there was no relationship between bacterial counts in different sections of the gastrointestinal tract or enzyme levels, filamentous bacteria were increased in E50 compared with E150. All of...

Trace metal contamination in estuarine fishes from Vitória Bay, ES, Brazil
Provedor de dados: 52
Autores: Joyeux,Jean-Christophe; Campanha Filho,Edmar Augusto; Jesus,Honério Coutinho de.
Muscular tissue from wild-caught mullet (Mugil spp.) and snook (Centropomus spp.) was analyzed by atomic absorption spectrometry to determine muscle contamination levels for cadmium, chromium, copper, lead and zinc and evaluate risks to human health associated with seafood consumption. Fishes were captured by subsistence fishermen in Vitória Bay, a Brazilian tropical estuary with numerous outfalls of untreated industrial and residential sewage. Based on the premisses that subsistence fisherman and local consumer show weak (culinary or other) preferences within the taxa studied, analyses were conducted and results are reported for genera. Snook cadmium, chromium, copper and zinc concentrations were positively correlated with size or weight. Mullet chromium...
