The secretary to the foreign investment board in Solomon Islands says six fishing projects approved last year were mostly Australian.
Derek Aihari says all the new projects want to get involved in fish exports.
He says the other fishing application approved in 2004 was from Malaysia.
Mr Aihari says while the newly approved applications for fishing are being implemented, he says local businesses will benefit.
"With the tuna fishing companies certainly they will help. But a lot of them transit their tuna products and export tuna straight away. But others supply our local fishing processing company, Solomon Taiyo and at times it'll help our smaller ones transport fish overseas. It will help our economy."
