Oh i have a "Degree in Enviro Science" thats just fantastic. I for one, am not interested in what you do or don"t have. Here's a "Couple of Quick Figures" then you can come to your own conclusions. 2010 NTH NSW 8 Week Period Clarence River 262 Tonne, 2012 only a 160 Tonne not a good season they reckon. Anyway lets say 1 fully Roed Mullet carries between 1.5 to about 4.5 million eggs average weight about 1.2 kg. Out of 262 Tonne 40% Females thats approx 176 Billion Eggs. I must say thats really good sustainable figures. Oh and Mr Degree, i suppose your part of the Enviroment Study for the Super Trawler.
