Le­gasea Po­ten­tial ben­e­fits from abun­dant fish­eries

Hav­ing six in­ter­na­tion­ally-renowned speak­ers fo­cused on defin­ing the econ­omy of abun­dance at the re­cent Fish­eries Sym­po­sium was a real boost for Le­gasea and pro­vided the vi­sion of more abun­dant fish­eries for all New Zealan­ders.

Around 100 at­ten­dees from var­i­ous back­grounds wel­comed the pre­sen­ta­tions from Daniel Pauly, Dr Eve­lyn Pinker­ton, Rob South­wick, Dr Glenn Sim­mons, Bruce Har­till and John Holdsworth.

Af­ter two days of dis­cus­sions at Snells Beach, the over­whelm­ing out­come was a col­lec­tive com­mit­ment to iden­ti­fy­ing the ex­ist­ing man­age­ment and pol­icy gaps and then com­mu­ni­cat­ing the need and ben­e­fits of restor­ing abun­dance and pro­duc­tiv­ity to New Zealand’s coastal wa­ters.

Pre­sen­ta­tions

Daniel Pauly is a Cana­dian-based award-win­ning ma­rine bi­ol­o­gist spe­cial­is­ing in hu­man im­pacts on global fish­eries. In 1995 he ob­served much of the his­tor­i­cal or anec­do­tal in­for­ma­tion on fish abun­dance was not used by the next gen­er­a­tion of sci­en­tists and man­agers. He called this ‘shift­ing base­line syn­drome’, where each gen­er­a­tion of sci­en­tists ac­cepts the state of de­ple­tion at the be­gin­ning of their ca­reer when eval­u­at­ing change.

His more re­cent work high­lights the risks as­so­ci­ated with the world­wide in­crease in fish­ing ef­fi­ciency and ef­fort, mask­ing the drop in catch rates, along with the de­ple­tion of top species and the ef­fects this has on the food chain. Due to the rapid in­dus­tri­al­i­sa­tion of fish­ing over the past 50 years, catch rates can no longer be con­sid­ered rep­re­sen­ta­tive of a species’ abun­dance.

Co-man­age­ment is Dr Eve­lyn Pinker­ton’s spe­cialty. Her rev­e­la­tions on how suc­cess­ful co-man­age­ment has been achieved be­tween the au­thor­i­ties and indige­nous peo­ple of Bri­tish Columbia were in­spir­ing. Suc­cess is de­pen­dent on coastal com­mu­ni­ties hav­ing di­rect con­trol of, and ac­cess to, their fish­eries and ma­rine re­sources.
