Risk Factors Affecting the Profitability of the Mediterranean Mussel (Mytilus galloprovincialisLamarck 1819) Farming in Greece

The Recruitment of the Endangered Fan MusselPinna nobilis(Linnaeus, 1758) on the Ropes of a Mediterranean Mussel Long Line Farm

“…Aquaculture of M. galloprovincialis has a set timeline which is as follows (Fig. 4): May-July spat collectors obtain spats which are then put into small hanging nets; once large enough, between August and October, the spat are then resuspended in larger nets at least at once prior to start harvesting early summer (Theodorou et al 2011(Theodorou et al , 2014. The significant date is the second renetting of the spats as it has been determined that early spat recruitment of P. nobilis takes place within the last week of August and the first week of September and can also be collected using a range of existing bivalve spat collection techniques (Cabanellas-Reboredo et al 2009b).…”

“…Therefore, prolonged air exposure during mussel handling justifies the application of short re-immersion periods (particularly in higher depths when water temperature is high). For bigger productions scales the farms should also assess the possibility of using faster grading methods or ideally invest in using a 'French type' grading machine (Theodorou et al, 2014;, which can grade up to 3000 kg h -1 and accordingly reduce handling time.…”

Evolution Through Innovation in Aquaculture: A Critical Review of the Greek Mariculture Industry

“…Limited space availability leads to marginal profitability and traditionally lower banking support compared to finfish. Happily, as the sector is less exposed to debt, it showed higher resistance to the economic crisis and has continued to export mussels (Theodorou, Tzovenis, Adams, et al 2014;). Nevertheless, restructuring is urgently needed to improve profitability.…”
