Fishery management regulations and market conditions are primary inHuence». Discards include those fish and shellfish which have lower or no market value, are damaged during harvest, or cannot be legally sold. Other organisms such as marine mammals, birds, and turtles are accidentally caught and discarded in some fisheries. Fishery management has intensified and undergone many changes worldwide in the last ten years, Methods used include restrictions of the catch quantity, fish size, and sex, Limited entry, trip limits frequency and landing liniits!, gear restrictions, area closures, and seasonsfurther restrict the fishing industry. Often more than one method is employed simultaneously. Great interest has been shown recently in privatizing harvestrights for fish and shellfishthrough individual transferablequotas ITQs!. All of thesemanagement options strongly inHuencebycatch and discardrates by either changingfishermen's behavior or altering the type of fishing technology used. Discarding of bycatch or lower valued fish high-grading! is among the most difficult fishery management challenges, Bycatch and discards make the attainment of the conservationand economicgoal» of fishery managersand the fishing industry problematic, The California SeaGrant College,in cooperationwith the National Marine FisheriesService, sponsored a nationalworkshop to addressthis critical issue. Twenty-two people from industry, agencies,and universitieswith knowledgeof discardproblems met in SanFrancisco January 29-3 l, 1990. Participants came from the Atlantic, Gulf, and Pacific coasts as well as Hawaii and Canada. The goal of the workshop and this publication is to stimulate multidisciplinary research,discussion, and innovative fishery management techniques directed at lessening fishery hycatchand discardproblems. The hrst two days of the workshop consisted of panel presentations and discussionsfocused on likely bycatchand discardproblem consequencesunder six primary managementschemes: unregulated, seasons,quotas, mesh restrictions, limited entry, and individual transferablequotas, On the final day, small discussiongroups brainstormedabout discard problems under each managementscheme and recommendedresearch needs and ideasfor lesseningbycatch problems. The informal style of the workshop yielded useful discussion of the problemsfrom both a biologicaland socioeconomicperspective. Weorganized these proceedings into the six management schemes discussed.Abstracts of thepanel presentations are followed by a summaryof theensuing discussions, Each management section scheme endswith the summariesof the small discussiongroup ideasand recommendations.Transcripts of mostof thepanel presentations
