Marcadores de Microssatélites para estudos de conservação da Raia-viola Rhinobatos percellens (Chondrichthyes, Rhinobatidae)

A exploração pesqueira, tanto artesanal quanto industrial, se constitui na maior ameaça à biodiversidade dos elasmobrânquios. Em escala mundial, o manejo adequado destes recursos é dificultado pela escassez de informações básicas sobre a dinâmica populacional destes organismos. A captura comercial de elasmobrânquios tem alcançado números alarmantes, com a inclusão de diversas espécies nas listas de risco de extinção nacional e também internacional. A identificação e a conservação de estoques geneticamente diferenciados e adaptados ao seu habitat, representam um ponto fundamental para o setor pesqueiro, pela sua relação direta com a produtividade total e o uso sustentável dos recursos. Entre as raias marinhas, a família Rhinobatidae é representada pelos gêneros Rhinobatos, Zapteryx, Trygonorhina e Aptychotrema, sendo registrada a ocorrência da espécie Rhinobatos percellens no Oceano Atlântico adesde as Antilhas e Panamá, Venezuela, Jamaica, Brasil, Uruguai, até a Argentina. No presente trabalho foram desenvolvidos marcadores moleculares do tipo microssatélites para raiaviola, Rhinobatos percellens, para serem utilizados em estudo populacionais. Cinco locus polimórficos foram isolados utilizando um protocolo de enriquecimento. Nos experimentos, foram testados 13 pares de primers, sendo 10 isolados no presente trabalho e 3 isolados para a espécie de tubarão azul (Prionance glauca). Dos primers isolados em Rhinobatos percellens, 5 são polimórficos, 2 monomórficos e 3 apresentaram bandas muito fracas, enquanto os primers testados de tubarão azul mostraram-se monomórficos. Todos os locus estão em equilíbrio de Wardy-Weinberg, exceto o RVA9 (de R. percellens). Os locus polimórficos apresentam de 3 a 6 alelos por locus e heterozigosidade média esperada de 0.62. Considera-se que estes marcadores polimórficos...(Resumo completo, clicar acesso eletrônico abaixo)

A influência do estresse sobre a qualidade da carne

The meat quality is evaluated by consumers according to their physical characteristics, such as color, texture, juiciness, tenderness and odor. The stress during the life of the animal and at the moment before the slaughter may be responsible for changes in the transformation of muscle into meat. Such changes may lead to the appearance of DFD (Dark, Firm and Dry) and PSE (Pale, Soft and Exudative) meats, which are poorly accepted in the market – because of their unusual aspect – and inadequate to industrial processing. Factors related to the handling, loading, transport, unloading, resting period and stunning are singled out as critical, since that, in these phases the animals are subjected to adverse situations to which they are accustomed. The aim of this study is to identify the process of ante-mortem and the slaughter itself in which the animals are subjected to stressful situations, as well as the consequences of stress on meat quality

Mapeamento da ilha da Trindade, Atlântico Sul

The area chosen for this study is the island of Trinidade, which is located 1167 km off the Brazilian coast, in parallel Victory at 20 ° 30'S and 29 º 19'W, being the most easterly point of our continent. The isolation of oceanic island of Trinidade leaves no noticeable that she is part of a large submarine volcanic chain oriented east-west lineament known as Vitória- Trindade. Along with the island of Martin Vaz, who is Federal Territory is administered by the Navy of Brazil. Both correspond to Source alkaline volcanic islands. The area of the island of Trinidad has approximately 10 km2. Geologically consisting ankaratritic spills, spills tannbuschiticos, volcanic tuff spills analcite-ankaratrite, phonolite spills, spills nefelinite, pyroclastics, spills grazinite, tinguaitos, olivine-analcitito, calcarenite dunes and wind according to Almeida (1961). The island has its base on the ocean floor, at 5,800 m depth. It is the only place still recognizes preserved volcanic necks and plugs, as well as remnants of a volcano in Brazil. Magmatism occurred here a sodium alkali-silica subsaturated where his wrist was last 50,000 years according to Almeida (1961). It is a place with restricted access due to their distance from the coast, his contribution and hard to be an exclusive area of the Navy. On the island with peaks occur up to 620 meters high, and its rugged mountainous terrain and difficult access to very specific points, as the peak of Desire, peak Fazendinha, Monument and other points on the island. Because of its location far from the coast, its small infrastructure, difficulty of landing and restricted access by sea, the island of Trinidad offers no possibility of tourism, being a military outpost, and scientific basis of great importance, which conduct research in area of marine biology, oceanography, geology and others

Cádmio, chumbo, cromo, mercúrio e níquel nos rios do estado de São Paulo e em peixes do Rio Sorocaba (São Paulo, Brasil)

To verify the levels of concentration of some heavy metals in fishes from Sorocaba river (São Paulo, Brazil) and evaluate if this contamination offers health risks to the fishermen, 63 samples of fishes collected from four points along the river were studied for cadmium, lead, chromium, nickel and mercury, with emphasis in this last, since it is the most toxic and most probable as a fish contaminant. Analyzing muscle samples by cold vapor atomic absorption spectrometry it was shown that the fishes are not contaminated. None of the five metals studied were present in prohibitive level and the fishes could be judged secure for human consume. It was also analyzed data from four years of cadmium, lead, chromium, nickel and mercury monitoring made by CETESB, from 1997 to 2000, in water from the main rivers of the State of São Paulo. The study pointed out that the majority of the monitored rivers still present contamination by those metals in a level that requires an improvement of the pollution control actions.

Characterization of the commercial fish production landed at Manaus, Amazonas State, Brazil

The present work aims to update a series of information about the regional fishing production, by presenting and characterizing the contribution of the different sub-systems of the Amazon basin to the catch landed at the main fishing market of Manaus, Brazil, from 1994 to 1996. Collectors specifically hired for this function registered key information on the fisheries. Thirty nine types or groups of fish were found in the fishing production landed. Jaraqui (Semaprochilodus spp.), curimatã (Prochilodus nigricans), pacu (Myleinae), matrinchã (Brycon cephalus), sardine (Triportheus spp.), aracu (Anostomidae) and tambaqui (Colossoma macropomum) were the most important items during three consecutive years. In 1994 these items summed up 91.6% of the total production; in 1995 and 1996 these values were, respectively, 85.3% and 86.4% of the total production. Tambaqui landed decreased remarkably during the period 1976-1996. There was a strong seasonal component in the production of the main species; jaraqui and matrinchã were mostly landed between April and June, while curimatã, pacu, and sardine were mostly landed during the dry season. Other important items showed a strong inter-annual variation in their production. The fishing production landed came mostly from the sub-system of the Purus River (around 30% of the total production). The subsystem of the Medium-Solimões contributed with an average of 15% and the sub-systems of the Madeira, Lower-Solimões, Upper-Amazon and Juruá, together contributed with 11.5% of the total production landed. Finally, the remaining sub-systems contributed with only 7.6% of the production.
