| This paper discusses the conditions of birth and growth of business networks in the veterinary drugs sector based on Brazilian examples examined by the authors. The beginnings of business networks are approached from two paradigms, one advocating the idea that the birth and growth of networks depend on some variables’ historical processes which define social networks, such as trust, cooperation and commitment, and another postulating that these attributes are not necessary for the formation of networks, it being sufficient to have only consistent economic expectations and a proper agreement.

| The objective of the present study was to investigate the influence of the establishment of dominance relationships and social stress on plasma cortisol and metabolite levels in Nile tilapia (Oreochromis niloticus). During the 30-day experiment, the fish weighing 236 ± 29 g were kept in individual aquaria, except for two pairings lasting 6 h each. Blood samples were taken from the animals before and after pairing. Display, approach, attack, rebuff, chase flight, and coloration were carried out on days 16 and 30. Activities and behaviors characteristic of the establishment of dominance relationships were described. It was possible to classify all experimental fish (N = 30) as dominant or subordinate. No differences were detected between dominant (N = 15)... |
