  1. Aqua Case Musselculture area-Chalastra Thessaloniki Exercise Find the appropriate distance between mussel socks based on the mussel condition index Sofia Galinou-Mitsoudi, OuraniaGiannakou, AmaliaMoriki

  2. The farmers of Chalastra hang the suspended socksdensely, leaving <40 cm betweenthem. • This operation exhausts the carring capacity of the mussel farm area producing underfed mussels. • Musselquality declines • The futuresustainability of the mussel activity in Chalastra is questionable. The subject

  3. To findthe most appropriatedistancebetweensocks for theChalastraenvironment. • To help farmers understand why they have to change their practices. Questions to answer: • In a mussel culture area, is the expression “more effort, more production" true? • How do we find the best distance between socks (e.g. 50, 60 or 90 cm)? • Which simple condition index is representative? The challenge

  4. To understand the connection between production quality and farming practices. • To identify mussel quality in terms of condition index, using different distances between socks. • To understand the temporal variability of the mussel condition index for production quality. • To estimate the benefits of different practices on yields and production costs. Learning goals

  5. GRAPH: Temporal variability of Hellenic mussel production and its benefit • MAP: Water drainage area and human activities • MAP: The extent of the mussel culture activity in Chalastra • MAP: The hydrodynamism of the area • MAP: Levels of chl-a in the mussel culture area of Chalastra In addition to the case the following information is supplied

  9. The currents in mussel culture area of Chalasta for NW prevailing winds ATEITH, 2007

  10. Levels of chl-a in the musselculture area of Chalastra SoHelMe, 2005 with modification
