Hope animal feeders are looking for better sources of feed oil.

"Fishmeal is also widely used as a food source for variety of purposes such as poultry, pigs, cattle and sheep. They can be of great importance in enhancing the quality of poultry and others by fattening them. fishmeal also fulfills all the protein requirements"

bob thanks for that youtube link in the ocean acidification thread.

however, your last link here doesn't address the fact that aquaculture generally exists is open water where the antibiotics are free to swim around and enjoy the currents.

obviously more is used in land based farming, but it's disposal isn't as readily distributed in the ocean.  same with pets.... sure they are given antibiotics.  but they are probably thrown in the garbage to  be in a landfill or they are flushed down the toilet.... and I think peoples antibiotics are more likely to end up in the ocean than the ones prescribed for pets.

What the last link clearly outlines is that there are individuals (in this case economics professors) who are critical of salmon farming, but have no idea about it.  Like I said before....If someone is going to be highly critical of something so strongly then take the time to learn something about it.  The professor in this case shows so much ignorance - making assumptions which are not even reality of the industry (at least here that is).

Land-based farming disposal isn't as readily distributed in the ocean?  If it ends up in ground run-off into tributaries or big rivers like the Fraser why couldn't it can eventually find it's way to larger water bodies - like the ocean?  What about all those farms between Chilliwack and Delta - could it not enter the Fraser River?  Once waste makes it's way to the Fraser River delta why couldn't it be distributed in the ocean?  According to the National Oceanic and Atmospheric Administration (NOAA), the biggest source of pollution in the ocean is land-based.  Apparently 80% of the pollution to the marine environment comes from land.

yes steven. it will eventually make it to the ocean... but it gets filtered by the ground,  processed or pollutes indiectly. 

in larger quantities yes. but not as direct

Filtered by the ground, processed or pollutes indirectly?  Hmmm.....well, if it "gets filtered by the ground" then why does NOAA suggest that 80% of the ocean pollution begins on land?  So pesticides and fertilizers are just "indirectly" making their way so that is not as bad?  We haven't even touched on storm drains or even ground water impacts.  How much precipitation falls in the Lower Mainland annually?  C'mon stop making me giggle, banx.

come on steve. I don't think i'm coming across correctly to you. I don't mean its 'filtered' in a good way. all of what i was saying is bad. terrible. just not good. and its not intended to make you giggle.

all i'm saying is its not as direct. yes it does make its way into water sources, obviously. in huge quatities. its just cows don't live in the ocean.

[shuswapsteve]

What does it really matter?  Both situations have waste that directly or indirectly (better to say non-point source pollution instead) goes into the water which ends up in the ocean.  Whether farmed salmon and cows do their business in different environments is a bit of a red herring.  Waste that comes out of the Fraser is free to swim around and enjoy the currents also.  However, it is pretty clear which activities share the bigger piece of the pollution pie as well as the main source of this pollution.

Marine harvest growing market size salmon on land.
