    The brown bullhead (Ictalurus nebulosus) has been settled in Europe at the end of Century XIX from North America. In Hungary it has been brought in 1902. The naturalization of this species was successful because the brown bullhead found adequate conditions for its life and reproduction in Hungary. But it was unsuccessful because lost its excellent growth.
    In inland water habitats-and that’s why also fishponds-extraordinarily multiplied, but because of its slight growth this species is undesirable for the native farmers. The brown bullhead is concurrent for domestic fish species, on the other hand its weight not more than 150-200 g. Occasionally it was exterminated, but multiplied again and again.
    In 1999 we placed out black bullhead offspring in a pool of a new intensive fish farm, in order to breed at least 300-350 g weight for the customers. The accidental trial was surprisingly successful. Consequently, the black bullhead prefers the artificial food, and produces excellent growth parameters and specific feed-live weight conversation ratio.
    On the 20th of September 1999 there was placed 23 300 pieces of brown bullhead offspring, with 28 g average weight and 625 kg gross weight. When we sold them on the 22nd of February 2000, the gross weight was 3387 and the live weight gain was 2735 kg. The gross weight of the feed was 3041,8 kg, and the feed-live weight conversation ratio was 1,11 kg/kg.
    Because of this successful trial the managers of the farm wanted to start systematic experiments to work out the details of the intensive farming of brown bullhead. We undertook to help to find the right place of the species in the Hungarian fish processing because of the increasing native and foreign demand.

  • Education and language teaching in the light of recent social and economic needs

    This paper attempts to describe several general educational potentials that are assumed to facilitate adequate pedagogical response to the recent economic and social paradigm shifts that have resulted in marked changes in the requirements for the labour force on the global job market.
    The article describes the most powerful pedagogical trends of the 20th century, selectively concentrating on the assessment of their contribution to and share in the preparation of the inevitably forthcoming paradigm shift in education.
    Topic related issues of language teaching in an academic setting are then discussed, focusing particularily on English for Specific Purposes, followed by a more thorough analysis of the major types of ESP syllabi. This analysis attempts to identify those properties that empower ESP teaching to give a more sophisticated answer (as compared to general language teaching) to issues raised by the appearance of new trends and needs in the
    global job market. 
    The paper offers conclusions for consideration as to the responsibility of language teachers and strategy makers in higher education, acting in an intercultural environment.

    Ethology, the research field of animal behaviour, during the past half century developed into an independent science and became more important in recent years as the farming industry has turned toward quality production. Farm animals respond for every environmental factor. Essential to know the answers to avoid unpleasant economic consequences. Based on the shepherds’ experience, this science has merged with modern technology, constantly expanding and searching new methods. According to the literature the article summarizes the observation methods in cattle grazing. This paper introduces the beginnings and shows the future trends. Finally we share personal experiences as the Hungarian Grey cattle grazing behaviour at conditions of Hortobágy, Hungary.
