Economic pressures on fishing

September 9, 2015 — Stocks of wild fish cannot be protected from overfishing in the long term by the expansion of aquaculture alone. Economic driving forces such as increasing global demand for fish or improved fishing methods will lead in future to increased fishery pressure on the most popular types of edible fish. Ocean researchers from Kiel and Finland come to this conclusion in a current study, which will be published online yesterday (September 8th) in the journal “Global Change Biology”.

Economists, fisheries and evolutionary biologists from Kiel University, the GEOMAR Helmholtz Centre for Ocean Research Kiel, and the Finnish University of Helsinki working together in an interdisciplinary project have calculated how fishery and aquaculture will develop in the coming decades in regard to popular types of edible fish such as sea bass, salmon, cod and tuna. These four are among the most important fish species on the North American and European markets. Salmon and sea bass come mostly from fish farming, while cod and tuna stem from wild-capture fisheries.

Powerful typhoon kills 11,000 farmed tuna in Japan: reports

Tokyo, Japan (AFP) — July 24, 2015 — A powerful typhoon which lashed Japan last week has killed more than 11,000 farmed bluefin tuna, costing over $10 million in damage, local media said Saturday.

Typhoon Nangka made landfall in southwestern Japan on the night of July 16 and slowly moved northward before turning into a tropical depression.

Torrential rain and gusts of wind wreaked havoc in various parts of western Japan, also causing high waves and clouding sea water in the fish farm near the Pacific coastal town of Kushimoto, Kyodo News and the Asahi newspaper reported.

Aquaculture’s Explosive Growth Means Farmers Are About to Run Out of Fish Food

July 14, 2015 —  The booming $170 billion aquaculture industry could face a shortfall of fish meal and fish oil for feed as early as 2016, and demand could outpace fish meal supply by up to 16 MMT (Million Metric Tons) in 2025. The mismatch will hasten the opportunities for alternative sources of feed such as plant proteins, algae and even insects, according to Lux Research.

Fish meal and fish oil are the lifeblood of the aquaculture feed industry, and demand is growing at 8% annually. The demand for fish meal will nearly double by 2025, creating a need for over one million tons of alternative high-protein meal.

“The future of fish feed is a blend of alternatives — no single source will dominate as fish meal has,” said Sara Olson, Lux Research Analyst and lead author of the report titled, “Tightening Fish Meal Supply Creates Opportunities for Aquaculture Feed Alternatives.”

Lessons for Alaska: Oregon Shellfish Hatchery Tackles Ocean Acidification

July 13, 2015 — A recent NOAA study pegged 2040 as the date for the potential end of Alaskan shellfish hatcheries. That is, unless serious mitigation efforts are put in place to combat ocean acidification. Last week we reported on the research, done at the Alutiiq Pride Shellfish Hatchery in Seward. Now, we’ll take a look at what a hatchery on the Oregon coast is doing to deal with these harmful changes in ocean chemistry.

The Whiskey Creek Shellfish Hatchery is located in the small town of Tillamook, Oregon.

“This hatchery was started by Lee Hanson,” says Sue Cudd, who owns the hatchery now. “It was really the first shellfish hatchery that was commercial in operation. It started in 1978.”

She studied biology in school, worked for an oyster company for a while, and then came on with Lee Hanson to learn about the hatchery world. From the 1970s until 2006, there were natural ups and downs, but overall, things ran relatively smoothly.

“Then all of a sudden, in about 2006, we started seeing some pretty major problems. Then from the end of 2007 to the end of 2008, we couldn’t produce larvae anymore,” says Cudd.

For a year and a half, they tried to produce. Even when they did manage to get some larvae, they wouldn’t survive and develop. It was a financial nightmare for the business.

“We lose money really fast because the production cost is the same without having any production. So, it was tough,” says Cudd. “We got help from some customers. The oyster growers association [helped] and one of our state senators got us some community development money, so we had time to be able to try to solve this problem. Without that, I don’t know what would have happened because we just lost money so fast.”

IFFO WELCOMES AQUACULTURE STEWARDSHIP COUNCIL RESPONSIBLE FEED STANDARD CONSULTATION

July 8, 2015 — On 30th June 2015, the Aquaculture Stewardship Council (ASC) issued their draft Responsible Feed Standard for public consultation. This is a welcome opportunity to comment on the proposals which form a wide ranging and demanding standard, encompassing environmental impacts, social and welfare requirements, energy usage and other criteria. The consultation document is well written, with clear guidance on where input is required and how this should be submitted.

Although the document also covers the ingredients used to manufacture compound feed, an obvious feature of the draft standard is that the vast majority of the criteria refer to ingredients from marine sources e.g. fishmeal and fish oil. The criteria for land based ingredients, whether vegetable or animal, are very brief in comparison. This is perhaps surprising given that the marine sourced raw materials are the minority of the formulation, typically 10-15% by weight.
