Why collect artisanal data?
• To quantify the contribution of artisanal fisheries to:
– Livelihoods
– Food security
– Employment
– GDP and terms of trade
– Culture
– Recreation and tourism
• To quantify the value of FADs
• For domestic and regional (WCPO) management
purposes
Need to know for better management
Scientific:
• Annual catch and effort of tuna and other pelagic fish?
• Interactions between commercial and artisanal fisheries?
• Effect of FADs on catch rates and size of pelagic fish?
Economic:
• Value of the contribution of the artisanal fishery to GDP?
• Are artisanal fishers profitable?
• What is optimum level of effort to maximise the economic benefits from the artisanal
fishery?
• Do FADs give a positive financial return?
Socioeconomic:
• What is the contribution of the artisanal fishery in terms of:
– Food security; and
– Employment and livelihoods.
• How effective are FADs in achieving their socioeconomic objectives?
• How many people benefit directly and indirectly from the artisanal fishery?
What is the artisanal tuna data collection
programme?
The main objective is to make total catch estimates for small-scale (or
artisanal & subsistence) fishing vessels that target tuna and other
pelagic species. Secondary objectives are to monitor length
frequencies and economic data for fisheries management.
Method
Catch and effort data is collected at the trip level by a combination of:
1. Logbook forms that collect catch and effort data at the trip level;
2. Fishing activity collects effort information (number of trips), which
is used to estimate logbook coverage and total catch and effort;
3. Length frequency sampling at a level of 5% (minimum) of total trips
to provide fishery management data.; and
4. Economic sampling collects fishing vessel cost data at the trip level

The Forms
Issues with the Forms
1. Fishing Event
The logbook form is set up to capture one ‘Fishing Event’.
A fishing event is a period of time in which a vessel uses one
type of fishing gear in one fishing area.
A new form should be started when a new or an additional
fishing event is started. This is important consideration in the
artisanal fishery as vessels often switch gears during the trip.
If you already have national logbook form for artisanal fisheries,
check whether it can capture ‘fishing events’.
Form issues contd.
2. Fishing Activity Form
Is a key form as it indicates the total number of trips that have been carried
out. Logbooks only indicate the catch for one trip.
It helps to gauge the logsheet coverage.
It can be difficult to implement this form, especially if you are aiming to
capture 100% of trips. Your ability to do this will depend on local conditions,
no. of boats / no. of fishery officers / budget / etc.
3. The final use of the fish
The logsheet form does not capture the final use of fish (sale, consumption,
price, etc) as this is not known at the point of unloading.
Market survey data is needed to capture this information.
(New Market Survey Manual being developed by CFP, SPC)
Form issues contd.
4. Vessel economic data
Does not collect fixed costs (or overheads) that are
incurred by SSF. The objective is to collect cost data at
the trip level to identify trends over time and the impact
that FADs have on cost per unit of effort at the trip level.
Excluding fixed costs does impact our ability to use
economics as a fishery management tool (MEY).
NEW ! Links with other data collection programmes
The same forms can be used to collect data from other vessel based fisheries.
Using the same form across different fisheries will make things easier for staff,
data management , etc.

TUF-ART DATBASE
• Based on the Industrial Fisheries Database – TUFMAN
• MS Access standalone database – not connected to TUFMAN, so can be
installed in an independent office (i.e. Coastal Fisheries)
•Data entry and basic reporting in place, further developments to take
place
Resources
