| Abstract Oryza sativa, the common cultivated rice, is one of the most important crops for human consumption, but production is increasingly threatened by abiotic stresses. Although many efforts have resulted in breeding rice cultivars that are relatively tolerant to their local environments, climate changes and population increase are expected to soon call for new, fast generation of stress tolerant rice germplasm, and current within-species rice diversity might not be enough to overcome such needs. The Oryza genus contains other 23 wild species, with only Oryza glaberrima being also domesticated. Rice domestication was performed with a narrow genetic diversity, and the other Oryza species are a virtually untapped genetic resource for rice stress tolerance... |

| The aim of this work was to verify by means of adaptability and stability analyses which genotype of Plinia sp. (jabuticaba tree) is more adapted to orchard conditions, based on the measures of stem growth and primary shoots. During a three-year period, the initial growth of jabuticaba tree genotypes from the native fruit collection of the Experimental Station of the Universidade Tecnológica Federal do Paraná - Câmpus Dois Vizinhos was evaluated. These genotypes included seedlings from forest fragments of the southwestern region of Paraná State and some from Minas Gerais State, Brazil. Analysis of variance (ANOVA) was performed, in a 29 x 3 factorial design, with three replicates in each treatment. Phenotypic adaptability and genotypic stability were... |

| La domesticación de hongos silvestres comestibles, particularmente de Morchella es actualmente una necesidad, generada por su demanda en los mercados nacionales e internacionales. Sin embargo, no se tiene establecido un procedimiento para su producción comercial y el 100% de la producción comercializada proviene de recolecta del bosque, ocasionando la degradación del recurso. Por tanto, para contribuir a la solución de esta situación se realizó la presente investigación, la cual integra dos etapas, una de reflexión teórica y la otra de estudios experimentales. En la primera, se efectuó un trabajo de análisis, identificando el papel del enfoque de Agroecosistemas y una propuesta conceptual de la domesticación para el caso de los hongos silvestres... |

| Domestication of Haliotis tuberculata has only recently begun. During the process, we expect that behavioural and physiological traits may evolve to become more adapted to their captive environment. These modifications may result from intentional selection of production traits or unconscious and unintentional selection due to conditions experienced in the farm environment. To study this process at the earliest stage, the progeny of 3 different broodstocks obtained from wild parents, selected farmed abalone and randomly sampled farmed abalone, were studied. After rearing for 16 mo in separate tanks, offspring from the 3 progenies were placed together in sea cages at the same density. After 3 yr, behavioural traits were studied, and the immune status after a... |

| The objective of this study was to test, using a field experiment, the effect of genotypic diversity on productivity of farmed populations (Ancud and Chaica, Chile) of the domesticated red alga Agarophyton chilense (formerly known as Gracilaria chilensis), a species considered as economically important in Chile. Monoclonal and polyclonal (4 and 8 genotypes) subplots were outplanted into the mid intertidal in Metri Bay (Puerto Montt, Chile) during summer, a season in which A. chilense face higher temperatures (>18°C) and low nitrogen availability (<4.00 μmol). Ancud farm genotypes show higher growth rates in the monoclonal rather than the two polyclonal subplots. A similar tendency, yet not significant, was discernible in Chaica. In addition, whatever... |

| La Mixteca Baja Poblana es una región con altos índices de marginación y pobreza extrema. En ella existe una especie conocida como “cuatomate” cuya importancia reside en ser una alternativa para el desarrollo económico y social. Aunque se han desarrollado algunos trabajos sobre la especie, pocos contemplan la importancia del conocimiento campesino en su proceso de manejo, conservación y domesticación, para explicar su permanencia e importancia hasta nuestros días. También son poco conocidos aspectos importantes del cultivo tales como su reproducción, manejo y conservación.

| The shrimp farming industry in the western Indian Ocean started with Aqualma’s project in 1989, and now several companies farm shrimp in the Mozambique Channel. Despite the remoteness of these projects and their high investment and operating costs, they compete in the global marketplace by efficiently producing high value quality products. To address sustainability and biosecurity issues, Aqualma developed domesticated specific pathogenfree (SPF) broodstock of Penaeus monodon from western Indian Ocean stocks, which have been its exclusive source of post-larvae since 2003. Specific molecular diagnostic tools have been developed for each endemic pathogen detected since 1996, and these are used for routine surveillance of Aqualma’s shrimp stocks along with... |

| Identifying genes and pathways involved in domestication is critical to understand how species change in response to human-induced selection pressures, such as increased temperatures. Given the profound influence of temperature on fish metabolism and organismal performance, a comparison of how temperature affects wild and domestic strains of snapper is an important question to address. We experimentally manipulated temperature conditions for F1-hatchery and wild Australasian snapper (Chrysophrys auratus) for 18 days to mimic seasonal extremes and measured differences in growth, white muscle RNA transcription and hematological parameters. Over 2.2 Gb paired-end reads were assembled de novo for a total set of 33,017 transcripts (N50 = 2,804). We found... |

| Commercially selective breeding of Atlantic salmon (Salmo salar) primarily for rapid growth may compromise cardiorespiratory robustness and its related phenotypes. Therefore, a suite of respiratory indices was used to evaluate aerobic capacity and hypoxia tolerance to test the hypothesis that exercise training can improve the athletic robustness in both domesticated and wild strains of Atlantic salmon, but with the domesticated strain having a less cardiorespiratory plasticity and a lower athletic robustness than the wild strain. We also tested a second hypothesis that a constant acceleration screening protocol should segregate fish according to athletic robustness based on their swimming ability. These hypotheses were tested with parr from Bolaks... |

| How may fish domestication participate in sustainable development of aquaculture? The development of fish farming currently compensates for the stagnation of fishery catches while the market demand continues to increase. The development of fish farming relies on an active diversification of farmed fish species. A diversification based on the farming of native species could reduce the environmental impact of fish culture and could better fit to needs of local markets. Such development could also favour a more integrated local economy. In this context, the building of a generic approach for multi-species domestication is required to optimise the use of the technical and financial means available for fish culture diversification. |

| Underlying consequences of domestication and artificial selection still remain largely unexplored in most aquacultured species. For species with a two phase life cycle, including the Pacific oyster Crassostrea gigas, most genetic studies have focused on the post-metamorphosis juvenile and adult stages, but relatively few considered the larval stage. To assess the consequence of hatchery practices on larval characters, especially growth, we performed a phenotypic study on larval progenies derived from crosses between Pacific oysters from natural beds and farmed Pacific oysters selected for desirable production traits such as rapid growth, for over seven generations. A set of three microsatellite loci was used to compare the genetic variability between the... |

| Because captivity constitutes a drastic environmental change, domestication is expected to induce a rapid genetic selection for behavioural traits. In this study, we searched for genetic differences in behaviour among brown trout juveniles from two strains differing for their domestication history, i.e. an almost pure native wild Mediterranean population (W) and an Atlantic domesticated strain (D). In order to assess pure genetic differences among strains, males from the two origins were mated with Mediterranean females to produce two experimental crosses (WW and WD). The swimming activity characteristics of individual WW and WD juveniles were compared before and after the application of a stress (light switched off suddenly, followed by a 5-min period of... |

| The development of fish and shellfish farming is facing several challenges linked to the infancy of the industry: i.e. domestication, genetic improvement of disease resistance, genetic improvement of feed efficiency to fish meal and fish oil substitution by vegetal products, development of adapted vaccines, supply of fry or spat at high quality and high robustness, adaptation to environmental change, production of healthy, high quality consumer products and limitation of environmental impact of the activity and escapees. Over recent years, the EU and individual countries have supported the development of genomic tools for some aquaculture species (e.g. rainbow trout, sea bass, sea bream, turbot pacific oyster, Atlantic salmon). New perspectives arise... |
