Sager01 and Bmilligan I posted on page 8 can you tell if my math is off?
The first fish farm I saw was when I was about 13 years old in Double Bay. The people that ran Double Bay at that time privately owned it. They raised the Chinook not Atlantic salmon to release so they could build the sports fishing around there. Right then and there, I wanted to be a fish farmer when I grew up. I started off my collage career at Sheldon Jackson Collage and my major was going to be Aquaculture. Funny we all grow up and end up doing something else. I for one would love to see fish farms supplying the world with fish so that the "commercial fleet" would not over fish our wild salmon. Is the water heating up and are the polar caps melting? Is that a cycle that has happened hundreds of times in the earths history? Most likely YES. Can we the human race stop it? Not so sure. I think the only ice age we were around for as a race was the last one and we think an asteroid caused it. Have we destroyed spawning habitat from logging & the Damming of major rivers? YES. Has the government opened up fishing in areas that should not have been opened up? YES. Has return predictions been wrong in the past so different fisheries were open when they shouldn’t be. YES. Who loves Gill-netters? Are the fish farms trying to follow the rules the Government set for them? Most likely YES.
THE BOTTOM LINE IS MISMANAGEMENT.
I realized this in the last report by the government about how the farms have been trying to comply with the government limit of 3 lice per fish before slice is used. In the report they stated in area 3.3 they tested 4 farms in the second quarter (spring to summer) showing the farms to have .0661 female lice per fish. But when we are talking about the pure numbers of salmon in a pen (I.E. 500,000) .0661 lice per fish is still way too many. 500,000(fish per pen) X .0661(female lice per fish) = 33,050(total female lice) X 100 to 500 (eggs per egg sack) = 3,305,000 to 16,525,000 X 6(sea lice have 6 egg sacks) = 19,830,000 to 99,150,000 (sea lice production per net pen)
That’s just one net pen there are reports that most farms have 3 net pens per site
3 X 9,915,000 = 59,490,000 to 3 X 99,150,000 = 297,450,000 lice per site production
27 sites in area 3.3 per their report = 27 X 59,490,000 = 1,606,230,000 to 8,031,150,000 Sea lice hatching in area 3.3.
Here is the report in pdf format please see pages 49- 51 & 106 if you don’t want to read the whole thing, But it’s a good read.

typical practice for fish farms
The eggs are hatched in the fall and then held in freshwater hatcheries and freshwater lake sites for 12 to 18 months. Then they are then transferred to marine sites from November through May. In saltwater, the salmon will continue to grow for another 18 to 24 months until they are ready for harvest and processing.
Tells me farmed salmon are good size when they are placed in with the sea lice and just about the right size to eat the pink salmon smolt. I wonder if they have scales yet?
e gads
Heres and Idea if you dont want to move on land why not decommision some large container ships and put the fish farms in a few of them. Bottom line there has to be a way to do it and not hurt our wild salmon. Create seperation
Closed containment is the way of the future. AgriMarine Industries is doing it right now. Evolve or become extinct the choice is yours.
