But then, what are the real improvements since the controversies of the Norwegian salmon industry ? Off course their blue mussels can be sustainable and even organic, but what about their salmons which main webpage is inaccessible? When inquiring on local actors in aquaculture, it’s always back to pledges for sustainability without enough real described actions stated, aside from philanthropy.<ref>“Mitigating against litter, pollution and lost or abandoned marine debris” but how and with what investments?

The 2018 report made by the Canadian Aquaculture Industry Alliance is not an independent view on the subject, but its observation are clear and sourced | The <u>2018 report made by the Canadian Aquaculture Industry Alliance</u> is not an independent view on the subject, but its observation are clear and sourced: *Good practices are described and promoted by the Alliance, but none of them seem to be mandatory. | ||
*When it comes to energy inputs, it is stated per unit of production, which does not consider the rebound-effect typical from those kind of improvements. But the oddest part is that it talks about decline while showing a rising curve. | |||
*The advantage of Canada’s coastline are their strong currents, where fish farms are placed to avoid an excess of organic deposition below, on the oceans’ bed. | |||
*Finally, the report often recognise the efficiency and beneficial ecosystemic services from shellfish farming; <u>which brings us to “Regenerative Ocean Farming”.</u><ref><small>“the use of “cleaner fish” (usually a member of the wrasse family), lice traps, the development of an eco-bath closed delivery system, and the use of full tarps for all net-pen therapeutant applications […] the trend in expenditures on energy used in production has declined on a $/tonne of production basis […] Canada’s farmed finfish feed conversion ratio is about 1.2:1. This means 1.2 kg of feed is needed to produce 1 kg of fish. This ratio has improved dramatically from previous decades, and is significantly lower than the FCRs for other sources of food protein: poultry (1.7:1 to 1.9:1), pork (2.8:1 to 2.9:1) and beef (6:1 to 9.1:1). […] Since 1990 the ratio of marine protein to produce 1kg of finfish protein has dropped from 3.8kg of fish meal and 2.8kg of fish oil to only 0.7kg of fish meal and 0.5kg of fish oil, a reduction of more than 81% and 82% respectively […] Locating marine farms strategically in areas of deeper water and strong currents, combined with mitigation measures such as site fallowing, help to minimize deposition from farms. Under federal and provincial regulations finfish farms are monitored for changes to the seabed. […] Pesticides used in farming seafood are evaluated by the Pest Management Regulatory Agency with strict environmental protection measures in place under the Pest Control Products Act. […] Recent studies reveal that farming shellfish can improve species abundance and diversity, have beneficial impacts on pelagic fish around farm sites, reduce pressure on wild stocks, and play an important role in stocking programs to replace depleted wild stocks.”</small> Canadian Aquaculture Industry Alliance, <i>The State of Farmed Seafood in Canada, 2018 Report</i>. https://naia.ca/application/files/9315/4998/1451/TheStateofFarmedSeafoodinCanada2018_Report.pdf | |||
