Abstract

It is generally acknowledged that more competitive marketing of Australian fisheries and aquaculture harvests requires closer attention to post-harvest technology. Historically, these products have been marketed in a variety of forms (e.g., for freshwater crayfish:- boiled fresh, boiled frozen, whole or tails, and live). Some of these forms present a product of actual, or perceived, poorer quality to the retailer and consumer and, thereby, obtain low prices.

Freshwater crayfish can survive out of water for extended periods and, so, can be economically transported alive to the (overseas) restaurant chef. This live product commands the very highest price for the grower. The survival and quality of the crayfish upon receival can be considerably enhanced by careful handling during harvesting and by adequate purging and packaging techniques during processing. As well as the export of live western rock lobsters (Panulirus cygnus) to Japan for several years, Western Australia is developing considerable expertise in this "value-adding" technique for overseas marketing of marron (Cherax tenuimanus) and yabbies (C. destructor-albidus).

One of the authors (WM) has recognized the need to establish a standard industry value for the weight loss of marron during live transport. The main aim of the industry experiment reported in this paper, and carried out on a commercial farm, was to estimate the weight margin that needs to be added to the stated weight of crayfish supplied, so as to allow for their weight loss during transport.
