Effect of Photoperiod Manipulation on Spawning Time and Performance of Turbot (Scophthalmus maximus)

Temperature and photoperiod are known as the main stimuli of seasonal reproduction in fish. Turbot (Scophthalmus maximus) is a spring spawning teleost fish species with a promising aquaculture potential and high market value. This study was conducted to assess the effect of photoperiod manipulation on spawning time and spawning performance of turbot. A total of 28 mature turbots from the Black Sea population were subjected to manipulated photoperiod (a photoperiod regime that fish would naturally receive three months later) and natural photoperiod for almost a year. While the fish exposed to natural photoperiod spawned in May, the fish exposed to manipulated photoperiod spawned almost three months earlier compared to the natural photoperiod group. Reproductive and hatchery performance of the manipulated photoperiod and natural photoperiod groups were similar. It can be emphasized that photoperiod play an important role in accelerating maturation and spawning. The findings of this study could be implemented in the turbot aquaculture industry to advance production.

TUTELA ANTECIPADA ANTECEDENTE, PRODUÇÃO ANTECIPADA DE PROVAS E PANDEMIA: UM DIÁLOGO NECESSÁRIO

The text deals about the procedural institutes for the anticipated production of evidence and for the previous anticipated sentence, as foreseen in the Code of Civil Procedure, in the critical context of the Covid-19 pandemic. Based on practical examples in comparison with the theoretical analysis, it is emphasized that the stabilization of early guardianship adequately and conveniently shelters emergency and transitory situations. Likewise, the advance production of evidence proves to be an important instrument for the reconstruction of facts related to the impacts of the pandemic on legal relations, allowing interested parties to resolve disputes by self-composing methods or, through prior knowledge of the facts, better evaluate your chances of success in future demand, avoiding judicialization as appropriate. To achieve the desired goals, the inductive and deductive methods are applied, without prejudice to, at times, adopting dialectical discourse. The research is applied, qualitative, legal-exploratory and bibliographic.

Produktionsplanung unter Berücksichtigung des Energiebezugs*/Production planning with energy supply restrictions

Der Energiebedarf einer Fabrik wird – neben den Energieverbräuchen der eingesetzten Produktionsressourcen – wesentlich von der zeitlich vorauslaufenden Planung beeinflusst. Mithilfe eines Energiebezugsplans sowie einer energieorientierten Produktionsplanung kann die kostengünstige Abstimmung von Energieangebot und -nachfrage einer Fabrik umgesetzt werden. Dabei gilt es, die Planungssysteme einer Fabrik zu befähigen, sich an die Bedingungen des Energiemarktes beziehungsweise der Erzeugung flexibel anzupassen.   The energy demand of a factory is determined by the specific energy consumption of the resources used as well as by advance production planning. An energy supply plan in combination with an energy-oriented production planning process aims for a cost-efficient adjustment of the energy demand and supply. The specific goal is to enable flexibility within the fatory’s planning systems in order to adapt the production processes to the volatile energy market and to the conditions of energy generation.

Unidades de Conservação no Pantanal do município de Aquidauana-MS: uma análise da evolução do uso da terra e cobertura vegetal e suas implicações / Conservation Units in Pantanal in the municipality (...)

Diante do avanço da produção econômica no Brasil e os consequentes impactos sobre os recursos naturais, a criação do Sistema Nacional de Unidades de Conservação – SNUC, Lei 9.985/2000, determina importantes normatizações e incentivo às medidas de conservação de áreas naturais dos diferentes ecossistemas brasileiros, na busca da difícil compatibilização do desenvolvimento econômico com a proteção à natureza. No estado de Mato Grosso do Sul, município de Aquidauana, as medidas de proteção ambiental são essenciais em virtude das características peculiares do ecossistema Pantanal. Com o objetivo de levantar informações acerca das condições ambientais das Unidades de Conservação no Município de Aquidauana-MS, o estudo propõe uma análise preliminar da evolução do uso da terra e cobertura vegetal das Unidades de Conservação que abrangem a área do Pantanal, referente ao período de 1987 a 2012. Os procedimentos metodológicos adotados consistiram no levantamento bibliográfico, cartográfico, iconográfico e da legislação existente, bem como análise da legislação. Os resultados indicam considerável preocupação em relação ao avanço da pecuária e consequente perda da vegetação nativa, implicando na necessidade urgente de monitoramento e gestão ambiental para medidas de conservação do Pantanal. Palavras-Chave: Pantanal; Unidades de Conservação; Gestão ambiental AbstractAs a result of the economical advance production in Brazil and the consequent impacts on natural resources, the creation of the Conservation Units National System – SNUC, Law 9.985/2000, determinates important regulations and incentive to the conservation rules for natural areas in the different Brazilian ecosystem, seeking to have the difficult compatibility between economical development and the nature protection. In the state of Mato Grosso do Sul, municipality of Aquidauana, the environmental protection measures are essential due to the singular characteristics of the Pantanal ecosystem. Aiming to collect information about the environmental conditions of the Conservation Units in the municipality of Aquidauana-MS, the study proposes a preliminary analysis of the evolution of the land use and vegetal coverage in the Conservation Units that include the wetlands of Pantanal, referring to the periods from 1987 to 2012. The methodological procedures adopted consisted of literature, cartographical and iconographical survey as well as the existing legislation study. The results indicate considerable concern about the cattle breeding rise and eventual loss of the native vegetation, implying the urgent necessity of monitoring and environmental management for Pantanal conservation measures.
