These studies of halieutic ecology produced at the request of Electricité de France by the French Institute of Research for Exploitation of the Sea in the Normand Breton Gulf must constitute one of the elements making it possible to come to a conclusion or not on the feasibility of the tidal power plant construction project; these studies have three parts: The first part discusses halieutic zooplankton. In the first place, the main species that constitute the exploitable living resources are considered, observed from the first stages of their life, in the egg or at different larval stages preceding the juvenile state. Also of interest are certain holoplanktonic groups. The whole of these observations establishes the status of zooplanktonic populations...

In 1972, France underwent an oyster (Crassostrea angulata) crisis and urgently needed to diversify its aquaculture. Thus, Asari clam (Ruditapes philippinarum) was introduced at that time for aquaculture purpose, concomitantly with the introduction of Pacific oyster (Crassostrea gigas). All Asari clam adults and spat originated from the same area (Puget Sound, WA, USA). After a promising start and the implementation of a national Research &amp; Development program, Asari clam culture rapidly faced a series of concomitant handicaps: firstly, in spite the fact that cultural practices were optimized and locking points addressed, leasing ground availability was limited during the 1980s’ due to certain reluctance from oyster farmers to share their leases and/or...

Provedor de dados: 42
Autores: Peixer,Janice; Giacomini,Henrique C.; Petrere Jr,Miguel.
The Emas waterfall in Mogi-Guaçu River is regionally recognized as an important fishing spot and touristic place. The first reports of the professional and sport fishing there date back from the 30's, which is the same period when the tourism took place. The present paper provides an environmental valuation of this place and an assessment of the differences among the major groups of people using the area. During 2006 we interviewed 33 professional fishers, 107 sport fishers, 45 tourists and 103 excursionists in order to estimate the Willingness to Pay (WTP) for each category and to analyze the influence of socioeconomic factors by means of logistic regressions and ANCOVAs. The WTP of professional fisher was significantly influenced by age and education,...
