Fish Farming – Bio-security for Fish Rearing: Re-circulating Aquaculture Systems

March 11, 2018 International News, National

Re-circulating Aquaculture is a technique for raising water borne animals in a closed (usually indoor) system which minimizes water consumption, provides maximum control of the livestock’s environment, and reduces the risk of exposure to parasites, disease, and predators High Density Re-circulating Aquaculture System (HDRAS) is a system in which aquatic organisms are cultured in water which is serially reconditioned and reused. Closed-system aquaculture presents a new and expanding commercial opportunity. Re-circulating aquaculture systems (RAS) are tank-based systems in which fish can be grown at high density under controlled environmental conditions. They are closed-loop facilities that retain and treat the water within the system. >click to read<09:33

The New England groundfish debacle (Part III): who or what is at fault? Nils E. Stolpe/FishNet

It took me a while to decide how to most accurately describe the situation that has been visited upon the New England fishing communities that are and since colonial times have been dependent on the groundfish fisheries.

NILS STOLPE: The New England groundfish debacle (Part IV): Is cutting back harvest really the answer?

While it’s a fact that’s hardly ever acknowledged, the assumption in fisheries management is that if the population of a stock of fish isn’t at some arbitrary level, it’s because of too much fishing. Hence the term “overfished.” Hence the mandated knee jerk reaction of the fisheries managers to not enough fish; cut back on fishing. What of other factors? They don’t count. It’s all about fishing, because fishing is all that the managers can control; it’s their Maslow’s Hammer.
