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.

As fisheries biologist Bob Martin tells Hatchery International, the program is a state-level agency program, but funded by a city.
A 40-minute trip in a light aircraft – or a five-hour ferry ride – separates the north side of the Comau Peninsula and Puerto Montt in Chile.

Following the first part of the series of four articles based on the use of energy in recirculating aquaculture systems (RAS), the question is whether or not we measure energy consumption and how. Is the energy consumed within the system monitored? Do we know where in the system it is mostly consumed? Which factors are affecting such consumption?
Despite its roots as the common carp, Cyprinus carpio, and all that fish means in aquaculture, the koi is not a food fish and is outside the scope of mainstream aquaculture. In recent years however, the koi has become associated with recirculating aquaculture systems (RAS). With the rise of aquaponics, the raising of fish in a RAS providing nutrients to a hydroponic system, some producers are choosing to fuel their plants with koi instead of crop fish like tilapia (Oreochromis spp.) Koi provides the aquaponic producer with many of the benefits of aquaponics while focusing their entire effort on plant production.

The reliable production of high quality offspring is paramount for successful aquaculture. This is true for both a shift from quantity to quality in established species as well as for closing the lifecycle of new candidate species. High mortality rates can occur in hatcheries if abiotic and biotic conditions are not within tightly framed optima, which is a consequence of the reproductive strategy of many teleost fish species.
