Haulena is a well known Canadian marine mammal skilled who heads the Vancouver Aquarium's animal well being program. He says the ocean lions goal the farms as a result of they're crammed with 1000's of grownup Atlantic salmon. Nevertheless, he's fast so as to add that the simple feeding floor can flip lethal if an animal will get tangled within the enclosure's quite a few nets.
"We have had animals drown in nets and sea pens earlier than," stated Haulena. "I believe the problem is actually about exclusion and being cautious with the gear to ensure sea lions cannot get trapped contained in the farms."

Lewis has lengthy opposed fish farming and is looking on the federal authorities to take away all amenities in Clayoquot Sound.

In line with the affiliation, the sector is the province's primary seafood export and is "designated a vital service by federal and provincial governments." The trade additionally says it generates "$1.2 billion in financial exercise" and if unable to function then "greater than 4,700 jobs in danger in communities" like Courtenay, Comox, Port Alberni and Tofino."
"We merely would not have sufficient fish within the ocean and we won't proceed to reap wild salmon, or wild fish of any quantity in the way in which now we have to fulfill inhabitants demand," stated Kingzett. "We're additionally looking for financial alternatives in areas of Vancouver Island which were depressed due to the declines in jobs for our useful resource extraction sectors, sothis is a sector that is essential."
