Why Salmon Farms have to come Out of the Water

In this report, we take a close look at semi-closed and hybrid Moreover, nowhere in the world is the use of such systems netpen systems and consider their ability to control the mandated: even in progressive Norway, where research two main impacts of the farms on wild salmon: and development has been heavily subsidized, the transmission of sea lice and effluent- operators are not obliged to contin. [...] It The best that can be hoped for from a semi-closed system is that seems that none of the innovations involving pumping seawater the ingress of lice to the farm is slowed somewhat, giving the through semi-closed systems and oxygenating it has solved the operators more time to try to meet their licence obligations for problem of water exchange for the growout of market-sized fish. [...] We imagine it must be intended for the continental shelf, if it to deliver sufficient treatments to maintain lice levels below is to be anchored; and the shelf is the home of all of the marine life the treatment threshold set by DFO for the protection of wild that we harvest and value for its role in our coastal ecosystems. [...] All that is required is to demonstrate that the would not ‘free up’ sufficient capital to support investment in prototype is capable of improvement in louse control, escapes the order of the hundreds of millions of dollars that these same and/or pollution in order to convert the licence. [...] LIQUID Without far more information, it is impossible to say whether the pumps on SEAWATER EFFLUENT INTAKES the system were inadequate to the clean water needs of the farmed salmon; OUTFLOWS or whether those pumps were in fact drawing contaminated water due to the proximity of the intakes to both the liquid effluent and the mound of rotting fish, SOLID WASTE OUTFLOW fish feed and feces that built.
