En la segunda de una serie de dos partes, Steven Summerfelt analiza varios esfuerzos para mejorar el conocimiento de los sistemas de contención cerrada y las innovaciones en la alimentación de los peces, y presenta comentarios finales exhaustivos.
El reciente Taller de Innovación Acuícola de 2017 en Vancouver reunió a numerosas partes interesadas involucradas e interesadas en el cultivo de peces, en particular los salmónidos, en la creciente industria de los sistemas de contención cerrada.
In the second of a two-part series, Steven Summerfelt discusses various efforts to improve knowledge of closed-containment systems, innovations in fish feed and presents comprehensive concluding remarks.
The recent 2017 Aquaculture Innovation Workshop in Vancouver brought together numerous stakeholders involved in and interested in fish farming – particularly salmonids – in the growing industry of closed-containment systems.
German researcher believes that floating fish feces – stemming from cork used in feed blends – would help recirculating aquaculture systems more efficiently remove suspended solids. The big question is, will feed manufacturers get on board?
Woodchip bioreactors can efficiently remove nitrate, phosphorus and total suspended solids from aquaculture wastewaters. Denitrification treatment of the relatively organic-rich aquaculture wastewater is a new and useful application to protect against water pollution.
A number of large salmon farming companies are now investing significantly to increase land-based, water recirculating aquaculture systems (RAS) in northern Europe and North America, and there is likely a need for more trained farm personnel to run and manage
A recent study evaluated the effects of a fishmeal-free diet on Atlantic salmon performance and fillet quality during successful growout to market-size in a commercial-scale, land-based, closed-containment system using water recirculation technology. Test fish performed well, with 97 percent survival
To evaluate the application of an air pressure-based transport method within a recirculating aquaculture system, the authors performed testing with harvest-size salmon at The Conservation Fund Freshwater Institute.
