Mussel farms threatened
The Thermaic Gulf ‘s marine environment is host to a large number and variety of human activities (tourism, fishing, ports and sports, among others). Although it is difficult to estimate the sum of the gulf’s economic benefits, according to a survey by Thessaloniki University’s Biology and Civil Engineering departments, these activities provide an income for at least 150,000 families. A typical example of how pollution affects local communities directly are the mussel farms in the gulf that employ hundreds of people in three prefectures. In the prefecture of Thessaloniki alone, there are 60 official and 250 more unofficial mussel farms, but for the past two months there has been a ban on the sale of mussels from the western end of the gulf. This year there was a considerable reduction in the shrimp catch in the gulf. Although many are saying this is a passing phase, several fishermen are attributing it to pollution. The Protection and Development Department was set up to act as an umbrella organization for all related authorities that are now divided among five ministries, four prefectures, eight business firms, organizations and associations, three research foundations, the regional government, and also two universities. From early July, the oceanographic research ship Aktaion has been taking samples at 50 specific points from Epanomi headland to the mouth of the Aliakmonas, analyzing 10 different physical, chemical and biological parameters to form a picture of the existing situation in the gulf and to propose solutions, according to the department’s director. According to sources, a series of measures to deal with the problem are under consideration for industrial, social, tourism and cultural development throughout the Thermaic Gulf and an information campaign is to be launched, beginning with schools.
