CONCLUSIONS Present management of harvesting strategies of all species is good  Splitting up of the seaweed resources should not occur to the detriment of present harvesters. Seaweed and in particular kelp needs to be treated as a separate fisheries, which its own management structure, as at present it is considered low priority given its size in relation to fisheries.  However given the secondary conversion from fodder to abalone feed and the increase in demand it has the possibility of becoming a larger fishery.
