  Citation × Citation Citation Abstract Copy Title: Sea Turtles of Bahia Magdalena, Baja California Sur, Mexico: Demand and Supply of an Endangered Species Author: Garcia-Martinez, S., Nichols, W.J. Year: 2001 Sea turtles have historically been a primary resource for many of the coastal inhabitants of Bahia Magdalena, Baja California Sur, Mexico. Despite their endangered status and the implementation in 1990 of Mexican laws prohibiting the harvest of sea turtles, the demand for and the supply of these animals has persisted to some degree. To determine the current demand for sea turtles 122 surveys and 56 interviews were conducted (June 12th-30th, 1999) throughout the Bahia Magdalena region. Through a generalized least squares (GLS) analysis it was estimated that 35.7% of the variation in demand was explained by six independent variables. The GLS model shows that the family size, special occasions of consumption such as birthdays, and the decline in sea turtle populations positively affect the demand function. The person's occupation, monthly income, and the 1990 ban on sea turtle harvest negatively affect this demand. Ninety-four surveys and seventy interviews conducted in the region (July 24th-August 1st, 1999) were used to describe a supply function. The GLS estimation indicates that 27.8% of the variation in the supply of sea turtles in the bay is influenced by nine variables. Age, level of education, fishing practices, number of dependents, availability of sea turtles, and culture significantly affect the supply of sea turtles in the Bahia Magdalena region.

  Citation × Citation Citation Abstract Copy Title: Important Factors Influencing Rule Compliance in Fisheries Lessons from Danish Fisheries Author: Mathiesen, Christoph, Nielsen, Jesper Raakjaer Year: 2001 This paper presents the results of a research project, which has focused on Danish fishers’ acceptance of imposed fisheries regulations and their respect for the management system. The analytical framework developed by Raakjær Nielsen (1998) and Raakjær Nielsen and Vedsmand (1999) has been used. The research has focused on three Danish fisheries: the cod fishery in the Baltic Sea, the demersal and Nephrops fishery in Kattegat and the fishery for non-human consumption species in the North Sea. The research is based on interviews with 56 fishers and a mail survey covering all vessels in the three selected fisheries. The following factors are concluded to have a major impact on rule compliance in fisheries: 1) the economic gains to be obtained; 2) the risk of being detected and the severity of the sanction; 3) the compatibility between the content of the regulation and the fishing patterns and practise; 4) regulation leads towards stock conservation; 5) norms, in particular the behaviour of other fishers and the moral of the individual fisher. In addition there are some indication, that co-management is important for rule compliance.
