The first step is figuring out which varieties are best suited to your region, the specific conditions in which you’ll raise them, and to your personal preferences. Although crayfish will survive and grow without supplementary feeding, best growth rates are achieved with an augmented food supply. Over these years, we’ve faced an extraordinary array of challenges. The water requirements of a fish farm are quite different from that of almost any other activity. See how we do it. The table below summarizes the operational status of the majority of US-based RAS projects that I am aware of that were developed over the past 20 years.

This list almost certainly misses numerous smaller projects that also were developed during this timeframe. [6] Those that typically suffer from reductions in output over time due to accelerated fouling, which requires regular and costly maintenance and rehabilitation. These species and spiny crayfishes in general, are considered to have little aquaculture potential because of their slow growth and low meat yield. These are the yabby (Cherax destructor), which is found throughout much of New South Wales, Victoria, South Australia and Queensland; the marron (C. tenuimanus), which is native to south west Western Australia; and the redclaw (C. quadricarinatus), which is native to northern Queensland and the Northern Territory. Every year, millions of anchovies, sardines and other small fish are caught from the ocean to be fed to fish in fish farms. South Australian Department of Fisheries and NSW Fisheries.
