Highlights of SciCOFish Coastal
Fisheries Finfish work
SciCOFish Steering Committee meeting
Noumea, March 2015
Coastal fisheries
• Provide 50%–90% of protein
intake for coastal communities
• Very important for local incomes
(provides around 50% of coastal
households with 1st or 2nd source
of income)
Fresh finfish key to food security

SciCOFish key work areas (Finfish)
Increased capacity, better science, for more
informed management
Multiple themes:
•
In-water assessments (including habitat
surveys)
•
Creel and market surveys
– Catch, effort, CPUE, prices, value etc
•
Biological sampling and demographic
assessments
– Length and age-based indicators, genetic
population structure
•
Ciguatera
•
Development of awareness/Information
materials
•
Capacity building
In-water assessments - Highlights
Training conducted in 6 countries in
UVC and habitat survey methods
– FSM 2010 (Aquarium fish; 8 staff)
– Kiribati 2011 (Environmental Impact
Assessment; 9 staff)
– RMI 2011 (5 staff)
– Samoa 2011 (Spawning aggregations; 8 staff)
– Tuvalu 2011 (4 staff)
– Fiji 2013 (12 staff)

UVC

Costly and time consuming
Logistically difficult
Easily biased
More informative approaches for assessing
fisheries available
Creel and market surveys - Highlights
Trials and training conducted in 9 countries
– Fiji, FSM, Kiribati, Nauru, Palau, PNG, RMI, Tonga, Tuvalu
– 82 in-country staff trained
Assessment reports produced for 5 countries
– Provide much-needed baseline data for future
comparison
Finalised draft of Creel & Market survey
manual
Developed, trialled and implemented new
database
Promotes standardisation of data and comparisons
over space and time
Coming soon in 2015 - Waterproof ID cards
(300 species)!!
Creel and market surveys – Highlights (2)
Ongoing survey programs
established in 4 countries

PNG (18 people employed)
Tonga (1 person employed)
Kiribati
Nauru
Palau, RMI, Tuvalu planning to
commence programs in 2015
Trainings regularly featured in
national media
– Promotes project, reaffirms official nature &
gets people used to surveyors
Biological sampling - Highlights
Training conducted in 10 countries
– Fiji, FSM, Kiribati, Nauru, Palau, PNG, RMI, Samoa,
Tonga, Tuvalu
– 92 in-country staff trained
2 ageing workshops held in Noumea (collaboration
with IRD)
– Fiji, FSM, Kiribati, Nauru, Palau, PNG, RMI, Samoa,
Tonga, Tuvalu
Ageing protocols developed for numerous coastal
finfish species
Ages estimated for > 2500 fish
Demographic assessments completed for 7
countries
– Length & age structures, growth rates, maturity schedules,
mortality rates
Genetic population structure / connectivity
examined for 10 species (collaboration with IRD)

Other highlights
Kept SPC at the forefront of ciguatera work in the Pacific and
globally
Workshop on standardising field survey methods for ciguatera collection and
detection, Hong Kong, 2012
Assisted Tuvalu with detection of ciguatera in fish and algae surveys
Co-facilitated training workshop on sampling methods and ID of ciguatoxincausing algae, Suva, July 2013 (collaboration between UQ, USP, FAO, IFREMER; 21
participants)
Workshop on fish and shellfish poisoning held in Noumea, Nov 2014 (60+
participants)
Other highlights (2)
Trained and mentored 6 Pacific Island Young Professionals
Developed information/awareness materials
Developed collaboration with research groups in the region and
globally (IRD, USP, UQ, USC, ZMT, SPC OFP)
Work plan for 2015 and beyond
• SciCOFish project concludes in September 2015
• Priorities for 2015
– Process remaining genetic samples and otoliths
– Finalise biological and genetic assessments
– Examine potential for otolith measurements to be used as
proxies for age (cheaper, easier)
– Develop biological sampling guides for key species
– Finalise, print and distribute creel and market survey manual and
ID cards
