Popis: Estimates are made of the maximal amount of chitin and astaxanthin that can potentially be retrieved from material of the South African West Coast rock lobster Jasus lalandii. Three different sources were investigated: (a) industrial waste from lobster processing factories, i.e. the cephalothorax plus legs, (b) whole lobsters, to represent material available on the beaches after mass strandings caused by red/black tides, and (c) exuvia, i.e. the entire exoskeleton that is shed during moulting (exuvia will be available regularly once industrial mariculture of J. lalandii is established). Industrial lobster waste contains 36g chitin kg−1 wet weight and 18mg astaxanthin kg−1 wet weight; whole lobsters have 43g chitin kg−1 and 13mg astaxanthin kg−1; and exuvia yield 159g chitin kg−1 and 63mg astaxanthin kg−1. The total theoretical amounts available from source (a) is 3.6 tons chitin and 1.8kg astaxanthin, from (b) 86 tons chitin and 27kg astaxanthin, whereas the amount available from (c) depends, of course, o...
