Progress Report Sustaining Fisheries and Marine Biodiversity in Bahia Samborombon: Strategic Planning Workshop Background For the past several years, the New England Aquarium (NEAq) and AquaMarina have been carrying out collaborative research with fishermen in Bahia Samborombon, Buenos Aires Province, Argentina. The goal of this research is to identify practical fishing methods and tools that can mitigate the unsustainable bycatch of the endangered Franciscana dolphin (Pontoporia blainvillei) in gillnets, while maintaining a productive fishery. The Bahia Samborombon and nearby Cabo San Antonio in northern Buenos Aires together have the highest bycatch rate of Franciscana dolphins within the species’ entire geographical range. Also, the existence of an isolated dolphin subpopulation in these two areas adds to the urgency of identifying prompt and timely conservation solutions. Drawing from this body of research into potential bycatch mitigation measures, our focus is now shifting towards helping fishermen and fisheries managers implement the most appropriate sustainable practices within this fishery. 2015 Activities During 2015, we implemented several projects intended to advance the implementation of the most promising sustainable fishing methods in the Bahia de Samborombon. The culmination was a national workshop organized to develop a multi-stakeholder strategy for achieving a sustainable fishery in the region.

AchievementsandPreliminaryResults

1. Ourcurrentbodyofresearchintopotentialtechniquesforreducingthebycatchof

Franciscana dolphins in gillnets includes changes in mesh size and gillnetting

locations; acoustic deterrents (pingers) in gillnets and their effects on dolphin

behavior;reflectiveandstiffnets;andalternativefishinggearssuchashand-lines

andfishingpots.Decisionsregardingwhichshouldbepracticallyimplementedand

the cost-benefits associated were discussed during the workshop (see below),

primarily considering those that have shown to be effective experimentally. A

complete assessment of this research will be included in the Final Workshop

Report.

2. Thefirsteversocio-economicstudyofthebay’sfisherywasconductedinOctober

2015 (Figure 1). The participants included 35 local fishermen representing 4

fishermen associations, and La Costa County authorities. Participatory

methodologies involvingbothqualitativeandquantitativeapproacheswereused

evaluate strengths,weakness, opportunities and threats of various options for

changing the status quo. Preliminary results showed that the main concern for

gillnetters involvedconflictswithlargetrawlersoperatingclosetoshore,thelack

of any law that legitimizes the artisanal gillnet fishery, overfishing, insufficient

plant that has a monopoly in the area. We are presently collecting additional

Government) inNovember2015.The“SustainableFishingPractices:Reductionof

Franciscana Dolphin Bycatch in Artisanal Fisheries” workshop involved 30

participants, including representatives of local artisanal fishermen associations,

non-governmental organizations, National and Provincial government officials

fromFisheriesandEnvironmentalAgencies,scientists,technicians,andexpertson

community-basedconservationanddevelopment(Table1;Figure2).TheFederal

Government’s Secretary of Natural Resources, and the Director of the Aquatic

ResourcesDepartmentformallyopenedtheworkshop.Theagenda(Figure4)was

designedtogetconsensusfromparticipantsaboutwhatshort-(3years)andlong-

Importantly, the national government formally recognized this workshop as the

first product of its National Action Plan for Reducing the Bycatch of Marine

Mammals,nowinfinaldraftformandlikelytoreceiveformalapprovalin2016.
