Clean Seas Tuna is at the mercy of its banks or the willingness of investors to pump more funds into its pioneering plans to commercialise the farming of southern bluefin tuna, after posting an interim loss of $9.3 million.

Clean Seas managing director Clifford Ashby said the group would look to raise money from investors in the June quarter to provide crucial funding, as it continues its attempt to become the first company in the world to spawn and grow commercial quantities of southern bluefin tuna.
