As the global demand for quality seafood rises, fish farmers are recognizing the need to gain greater control over their operations. More farms are exploring ways to create smarter, more sustainable operations and land-based aquaculture is emerging as a viable way to reduce risk and maximize profitability.

Since it was built in 2012, the Aquaculture Technology Centre (ATC) Patagonia held the genetic improvement program of Aquachile – which used to be the largest salmon producing company in Chile. Last year, before Agrosuper purchased Aquachile, Danish feed company Biomar acquired 30 percent of this facility and helped turn it into one of the largest experimental stations of its kind.
Cedar Crest Trout Hatcheries lies in Hanover, Ontario, Canada, at the base of the Bruce Peninsula, in the heart of Ontario’s rainbow trout (Oncorhychus mykiss) fingerling production area. This location is perfectly placed to ship fish to Cedar Crest’s primary clients on Lake Huron. In truth, Cedar Crest is four closely placed hatcheries, making Cedar Crest the largest producer of fingerlings in the province. Between the four locations, Cedar Crest produces more than seven million fingerlings each year.
Unglamorous as it may be, mortality collection, classification and analysis are an essential job at any hatchery. Often, mort picking is seen as the bottom end of the job spectrum.
The shellfish industry in British Columbia has at least two very happy people this fall.

When Eric Pederson of Ideal Fish needed European sea bass fry for his indoor RAS installation in Connecticut, U.S., he went to Europe to get them.
Given the unique nature of each RAS facility, maintaining a catalog of Standard Operating Procedures (SOPs) specific to your site is helpful. SOPs describe how essential routine tasks at the facility should be performed to meet quality standards. Up-to-date SOPs are a useful tool for training new hires and are a guide for continuity and quality assurance between staffing changes and work shifts.
Salmonids lay their eggs in gravel redds for a reason, yet the use of rearing substrate in salmon and trout hatcheries, is not a common practice.

The Canadian Federal Court has ruled that juvenile farmed salmon in B.C., must be tested for piscine orthoreovirus (PRV) before being introduced to open net pens.
Feed is the primary external input to recirculating aquaculture systems. It is therefore essential to design the feed correctly, as in RAS, we are not only feeding the fish, but also feeding the system.
"Sustainability” and “sustainable” are popular words these days, but often misused. We understand it as producing food while sustaining natural resources and achieving it only through production systems with minimal ecological impact.
Just a few years ago, someone touting the commercial viability of raising fish exclusively on land would have raised a lot of eyebrows. Today, the general attitude toward land-based fish farms – in various forms and sizes – is optimistic, particularly for salmon.
