Mussel Farms to clean up Salmon farms act.

Here is an interesting rebuttal by the Newfoundland Aquaculture Industry Association (NAIA) in the Indy to a previous negative OP/Ed piece on Aquaculture. He makes some really interesting and strong points for increasing aquaculture.

I'm glad someone did a rebutal of the letter to the editor by Lloyd C. Rees as it was ill informed and espoused what Mr Harry Tucker talked about as the Victim Mentality of NL'ians.
It is attitudes like Lloyd C. Rees espoused in his letter to the editor that makes NL the most scenic Ghetto in canada and will continue to be with attitudes his.

‘Fish farming
is anything but stupidity’


Dear editor,
I am writing in response to a letter
published in the Dec. 1 edition of The
Independent by Lloyd C. Rees headlined,
Cooke Aquaculture proposal
ultimate in stupidity. Mr. Rees is
incorrect in stating that Norway and
the United States are turning away
from aquaculture. Norwegian aquaculture
continues to grow and is the
third largest component of the economy
of Norway. The U.S. has passed
legislation to increase fish farming at
least five fold in the next decade to
counter a huge trade deficit on fish
imports. Fish farming accounts for 40
per cent of global fish production (80
per cent in China) and there are no
other sources to increase healthy fish
protein for human consumption.
Mr. Rees’ facts are confused. Cooke
Aquaculture proposes to produce
17,000 tonnes per year of salmon —
not 50,000 tonnes. He predicts this
will require 150,000 tonnes of raw
fish for feed from wild fish sources.
The reality is the fish he mentions are
not used in feeds, nor are they even
sourced in Canada. In fact, wild fisheries
have grown in all areas of
salmon and mussel farming across
Atlantic Canada, most notably the
lobster fisheries, according to two
independent studies from Atlantic
universities.
About 50 per cent of world fishmeal
is used to produce poultry and
pork and the other 50 per cent to produce
fish such as salmon. Pork and
poultry require three to four kilograms
of fish feed to make one kilogram,
whereas the ratio is about one-to-one
for fish farming — much more efficient
and environmentally sustainable
conversion of feed by most accounts.
Up to 99 per cent of the fish meal
used in fish diets comes from fisheries
certified as sustainable. According to
the United Nations, global fisheries
presently discard 40 per cent of the
fish caught at sea, so there are large
untapped sources of fish protein out
there.
Lastly, I hope that your readers can
read beyond Mr. Rees’ comments and
see that, in fact, fish farming is anything
but “stupidity” and that Premier
Danny Williams and Cooke
Aquaculture should be commended
for supporting such initiatives to revitalize
our province’s economy.

I'd be curious to know if Mussel aquaculture has ever been located in conjunction with Salmon aquaculture to help filter the water and improve or maintain water quality in and around salmon aquaculture ventures due to the water filtering properties of mussel aquaculture?

Especially when you consider the opportunities available for expanding Mussel aquaculture in our province and some of the problems currently being experienced in the bay of fundy in and around salmon aquaculture sites, causing sea lice and bottom pollution.

Here is an interesting article that highlights some of the problems and lessons learned from other Aquaculture ventures.

I'll post the whole thing because Trans continental only archives for a couple of weeks:(

Twenty years in the making

Greg Knott
The Coaster

Today, approximately 20 years after the birth of aquaculture industry in the Coast of Bays region many feel with recent large investments by outside companies, the industry has arrived and begun to mature.

“We recognize and have identified for sometime that aquaculture can provide some very meaningful employment for us as we diversify our economy here in the Coast of Bays region,” said Tracey Perry, executive director of the Coast of Bays Corporation (COBC).

Ms. Perry said the region is at a point now where it needs to begin assessing what infrastructure needs participating communities need to help the industry grow and flourish.

She explained they are currently arranging a meeting with all stakeholders including municipalities, companies involved in the industry, and representatives from both the federal and provincial governments.

“The more people that are informed about the types of issues we now need to address, the better job we’ll do at getting it done in short order.”

ISSUES

There are a number of issues Ms. Perry noted stakeholders need to examine to help the aquaculture industry.

One of those things is the availability of landfill sites suitable to accommodate the volume of feed bags used by the aquaculture sites. According to Ms. Perry, if a farm is growing three million fish, they will be consuming approximately one million dollars in feed each week.

“We have to have proper disposals sites for these feeds bags and we really need to get this in place relatively soon.”

The cost and manner of offal disposal must also be addressed to minimize the cost to growers and have no environmental impact. Offal is the discarded portion of fish after it has been processed.

Industry and the various stakeholders have to also look at the water treatment facilities located in each community.

“Where there is going to be processing for the aquaculture industry, we have to ensure we have sufficient water quality and water supply. We need to minimize sewage outfalls, and get into treated water and sewer facilities wherever aquaculture is being done as much as possible.”

They need these facilities to handle and pre-treat the harvest water and the processing water.

“Any processing facility where farm fish is being processed must have this water treatment facility. Being in a region that has traditionally processed ground-fish, this is also a new infrastructure need.”

BIO-SECURITY


A few years ago, in New Brunswick, there was an outbreak of an infectious disease among its farmed fish population that landed a huge blow to that province’s aquaculture industry.

“What they learned from that experience is that there should be more site separation. Sites should be rotated and fallowed on a regular basis. So if you use it for a year then you fallow it and give it a break for a year.”

Another big piece in bio-security is having separate in-flow and an out-flow wharfs. Ms. Perry said it is important to have one wharf dedicated to everything going out to sea, including small baby fish and feed, and one wharf dedicated to everything coming in from the sea, such as mature fish.

She said in some communities wharfs are used extensively and some communities need more room to accommodate everyone.

“They’re being used for the traditional fishery, they’re being used for aquaculture, they’re being used for ferries, and they’re also being used by recreational boaters.


CHALLENGES

For years the COBC has known about all the issues the growing aquaculture industry would face, but they could never justify the need for the construction of these wharfs and landfill sites to government until recently.

But now large scale companies such as Cooke Aquaculture and the Barry Group have arrived. Ms. Perry said the region needs extensive infrastructure improvement and now they can look toward funding agencies to help upgrade the facilities currently in the region to accommodate the growing aquaculture industry.

She credits the work done in the past done by the aquaculture pioneers in the region with helping to bring a meaningful and sustainable industry to the area for many years to come.

While the industry has come a long way since its early days, Ms. Perry said there are a number of challenges which must be met.

“These are all wonderful challenges that come with growth but it means that a significant amount of planning and prioritization will need to be done by all stakeholders in the region. Of course as we go forward we’re really going to need to do a lot of work as a region to put this infrastructure in place.”
