1. Genetic variability of tambaqui broodstocks in the Brazilian state of Pará
ABSTRACT The present study evaluated the genetic variability of the broodstocks of tambaqui hatcheries in the Brazilian state of Pará. Samples were obtained from the caudal fin of 110 broodstocks from one hatchery in each of four municipalities (Santarém, Peixe-Boi, Breu-Branco, and Ulianópolis), representing all the individuals of each hatchery stock.

2. The effect of structural enrichment in hatchery tanks on the morphology of two neotropical fish species
Reared fish differ from wild fish in several aspects, including morphology, because they are adapted to captive conditions that are totally different from natural conditions. To minimize the influence of the hatchery environment on the morphology of fish, the use of environmental enrichment through the incorporation of natural designs in captivity, has been

3. Genetic variation of wild and hatchery populations of the catla Indian major carp (Catla catla Hamilton 1822: Cypriniformes, Cyprinidae) revealed by RAPD markers
Genetic variation is a key component for improving a stock through selective breeding programs. Randomly amplified polymorphic DNA (RAPD) markers were used to assess genetic variation in three wild population of the catla carp (Catla catla Hamilton 1822) in the Halda, Jamuna and Padma rivers and one hatchery population in Bangladesh. Five decamer random prim

4. Análise comparativa da variação genética entre os estoques cultivado e natural de Prochilodus argenteus : implicações para o repovoamento de rios
Introduction of hatchery fish in river has been the major using strategy for river fishery rehabilitation, working to attenuate river damage in short time. But there are effective risks about their efficiency and results, concerning the pool gene preservation and illness proliferation, beyond others ecologies and economics aspects. At São Francisco river, d

5. Restriction site heteroplasmy in the mitochondrial DNA of Brycon opalinus (Cuvier, 1819) (Characiformes, Characidae, Bryconiae)
Homoplasmy is a feature usually found in the mtDNA of higher animal taxa. On the other hand, the presence of two classes of mtDNA in the same cell or organism is rare and may appear in length or site variation. Data from mtDNA RFLP analysis of Brycon opalinus populations (Cuvier, 1819; Characiformes, Characidae, Bryconinae) revealed site heteroplasmy from en

6. Mitochondrial DNA variation in wild populations of Leporinus elongatus from the Paraná River basin
Leporinus elongatus, a fish species widely distributed throughout the Paraná River basin in South America, is an important fishery resource and a valuable species in aquaculture programs. Despite its great economic importance, several wild populations have been suffering a drastic reduction. The comprehension of its population structure represents an import

7. Diversidade genetica do DNA mitocondrial em populações cultivadas e selvagens da Pirapitinga-do-Sul, Brycon opalinus (Cuvier, 1819) (Characiforme, Characidae, Bryconiae), na Bacia do Paraíba do Sul
.RFLP (Restriction Fragment Length Polymorphism) analysis of mitochondrial DNA was carried out to investigate the population genetic structure and its potential as a tool to identify and manage the cultured and wild populations of Pirapitinga-do-sul ? Brycon opalinus (Cuvier, 1819) (Characiforme, Characidae, Bryconiae) in the Paraíba do sul watershed. DNA s

8. Avaliação da sanificação da casca de ovos comerciais por agentes quimicos
Considering the high level of contamination on the egg shell and its high level of use on an industrial scale, eggs have become an important health risk to the consumer and a source of economic loss to the producer and the industrial sector. The objective of this work was to increase the efficiency of cleaning and sanitation using chlorinated compounds (sodi

9. Admixture analysis of stocked brown trout populations using mapped microsatellite DNA markers: indigenous trout persist in introgressed populations
Admixture between wild and captive populations is an increasing concern in conservation biology. Understanding the extent of admixture and the processes involved requires identification of admixed and non-admixed individuals. This can be achieved by statistical methods employing Bayesian clustering, but resolution is low if genetic differentiation is weak. H
