Rwanda’s fishless country

For Rwanda, as with other Central African countries, fortunes are to be found in aquatic life; an equitable source of food available to all regardless of status. Nevertheless, fish farming in this tiny Central African country is highly exposed to many factors, which for a long time, have hampered the production of enough fish.

Canada on a mission

Emerging science has led some conservationists to question whether hatchery production was a cost-effective restoration tactic and to sound alarms about the practice of releasing hundreds of millions of domesticated hatchery fish to mix with wild salmon.

Global tilapia research round-up

Tilapia is one of the world’s most farmed species, currently grown in more than 120 countries. It has a temperature tolerance that allows it to thrive anywhere from the Sub-Sahara to Scandinavia. The world’s top producers are China, Indonesia, Egypt, Brazil and the Philippines.


Waste characterization and recipe development for composting aquaculture sludge

Composting is an aerobic process where microorganisms are used to decompose organic matter. Typically, decomposed materials lose mass and moisture, accompanied by the transformation and release of nutrients, such as organic carbon, nitrogen, and phosphorus, into water-soluble forms and volatile gases (e.g. carbon dioxide and ammonia). » Read More...

Evaluation of a velocity assist inlet for improvement of hydrodynamics in dual-drain fish tanks

One type of fish tank used in recirculating aquaculture systems (RAS) is the Cornell-style dual-drain circular tank. Cornell-style dual-drain fish tanks have two drains: a bottom centre drain and an elevated sidewall drain. » Read More...

Assessing the toxicity of peracetic acid to early Atlantic salmon life-stages

Ubiquitous bacterial and fungal pathogens that reside in land-based recirculating aquaculture systems (RAS) and egg incubation systems can cause elevated mortality in juvenile fish populations under substandard environmental conditions. » Read More...

Hatchery 101: Climate change

Juggling environmental goals and animal welfare goals is a hard balance to strike in a hatchery. » Read More...

Hatchery 101: Energy efficiency

Optimizing your hatchery’s energy consumption can be as simple as turning off unessential electronics or as comprehensive as installing solar panels for an off-grid generator system. » Read More...

Hatchery 101: Water conservation

Water is the most important resource in a fish hatchery. Thoughtful and efficient use of this natural resource not only ensures production for many more years to come, but it safeguards the health and welfare of the fish stock. » Read More...

Hatchery 101: Waste management

In order to protect the natural resources that drive hatchery production, hatcheries must implement clear and conscious waste management protocols. » Read More...
