Economic assessment of Palmaria cultivation:<br />
at sea & in tanks<br />
Best yields of Palmaria after cultivation at sea obtained by settling spores on<br />
nets (3 x 1.3 m, with 10-cm mesh) and harvesting the nets after 5-6 months in<br />
the sea. Yield per net is 25-30 kg of wet Palmaria.<br />
Assuming that standard refrigerated container used as a hatchery, only 48 nets<br />
could be seeded and maintained prior to deployment, so total annual production<br />
of wet Palmaria would be 1.2-1.4 tonnes. At current prices, value of crop would<br />
be €3,000-5,000.<br />
Capital costs to install and equip container as a hatchery: €40,000<br />
Annual costs for consumables, electricity and labour: €90,000<br />
Unless yields can be greatly improved, cultivating Palmaria at sea will not<br />
provide basis for a viable business.<br />
Tank cultivation of Palmaria:<br />
Depreciation on equipment plus electricity for farm with 80x1-m 2 tanks: c.<br />
€8,000 per year.<br />
At 50 kg/tank, total yield of wet Palmaria would be 4 tonnes, worth €10,000<br />
(€14,000 if sold dry), so small margin available to pay for limited labour required.
