The Maine Technology Institute (MTI), USA has awarded
grants and loans totaling US$1.66 million to 27 Maine companies.
The cash, which ranges from $1,116 to nearly $500,000, will

One of the aquaculture beneficiaries is Maine Coast Sea Vegetables, Franklin which received $19,842 to help develop
seeded nets and ropes for seaweed
aquaculture.
The USA has halted imports of salmon from Marine Harvest's Chilean farms due to contamination.

violet.
