#HatcheryHack by Nicole Kirchhoff: Government, farm service agents, even utility workers are not the first responders to our farms in disasters, it is our fellow farmers. We are the ones on the ground, working to keep our animals and farms alive every second of the storm and immediately after the storm passes.

The Community Hatchery Program started in 2013 after the Ontario Federation of Anglers and Hunters launched the partnership with the Ontario government. With the help of over 2,300 volunteers who give 50,203 hours annually—which translates to about C$1.25 million (US$ 888,956) in-kind—these #hatcheries have stocked over 76 million fish into Ontario lakes and rivers since 2013.  “The volunteers are tremendous and often, I would say, in most of the communities, people, anglers, people in the community are probably not really aware of the investment that people are putting into their local ecosystems,” said program coordinator, Matt Burley.

Just Published – Nitrate levels are primarily controlled by the dilution rate in RAS without denitrification technologies. Therefore, understanding the nitrate tolerance of cultured fish is critical for establishing important facility criteria, including water use requirements, realistic fish production targets, proper RAS design, and end-of-pipe water treatment strategies. The interdependency of these parameters is explained in context to post-smolt Atlantic salmon production in this recently published Hatchery International article by FI researchers John Davidson, Curtis Crouse, Christine Lepine, and Christopher Good. Star-Oddi Hatchery International   #FIResearch #waterquality #RAS #salmon  https://lnkd.in/ePiDH7yK

#Aquaculture economists agree that imposing tariffs will shift a long-established free trade partnership in North America. It will likely trigger more inflationary pricing throughout the #seafood sector’s supply chain. However, when it comes to predictions on how this will impact the fish farmer, the vision remains unclear. Read more: https://lnkd.in/gqfQndAx #fishfarming #seafoodindustry #seafoodtrade #UStariffs

An American marine eco-physiologist and associate professor of #aquaculture and fisheries at the University of Rhode Island (URI) says that raising #seaurchins is part of a viable industry. Coleen Suckling said there are many projects on urchin farming taking place both on and off the URI campus, including optimizing hatchery production. She partnered with the region’s only urchin hatchery in Maine, hosted by the University of Maine’s Center for Cooperative Aquaculture Research, where they have been working to find the right conditions for producing juveniles, called seed, for farmers.

Engineers and scientists are working to design an electric barrier to deter fish from escaping downstream of the reservoir at Rathbun Lake. After years of #research and formal studies, the team found the most effective solution to be an intermittent underwater electric current. “The fish, when they are subject to an electric current underwater, depending on the strength and the type of electric current, they’ll have different responses. But if you get it just right, they will be deterred and won’t move through the electric field that is created,” said Leigh Mitchell, electric fish barrier project manager with the Kansas City District. https://lnkd.in/g-guY7EU #walleye #fisheriesmanagement

#FeedForThought by Magida Tabbara: Feeding fish at the early stages of life is a challenging process, and it is still difficult and overlooked in terms of studies. The nutritional physiology of larvae and early juveniles has been studied. But the process offering larvae commercial feed from the moment they lose their yolk sac is still complicated, especially in the case of marine fish. #hatchery #fishhatchery #fishnutrition #fishfeed #feedingstrategies

Recirculating aquaculture systems (#RAS) are designed to maintain water quality that matches the biological requirements of #fish. However, when RAS are operated with limited water exchange, harmful compounds can accumulate in the water. Over the last 15 years, the Freshwater Institute (FI) has characterized RAS #waterquality under different operating conditions while evaluating effects on fish growth, health, and welfare. Early studies identified accumulating nitrate, dissolved copper, and potassium as compounds that could negatively affect salmonids in RAS (Davidson et al., 2009; 2011).

Oxbow Hatchery, in Baker County, Ore., is undergoing renovations and will be open again in January to the public. Owned by Idaho Power Company (IPC), it was built in 1961 after the completion of Oxbow Dam on the Snake River. It is the first of four mitigation #hatcheries constructed by IPC to help in the restoration of #salmon and #steelhead runs on the Snake and Salmon Rivers in the northwest, according to information from Idaho Fish and Game.

Proud of my latest column for Hatchery International highlighting how every hatchery needs to be prepared for bigger and badder weather events. This past years Hurricanes in Florida really highlighted for us how climate change is very real and will be impacting every one worldwide, if it hasn't impacted you already.
