Why collect artisanal data, contd.
• To quantify the contribution of artisanal fisheries to:
– Livelihoods
– Food security
– Employment
– Culture and recreation
– Tourism
• To quantify the value of FADs (some obligations)
• For domestic and regional (WCPO) management purposes
What is the artisanal tuna data collection
programme?
The main objective of the programme is to provide total catch estimates for
small-scale or artisanal/ subsistence vessels that target tuna or pelagic species.
Method
Catch and effort data is collected at the trip level from small-scale vessels that
regularly target tuna or pelagic species.
Logbook forms are used to compile this data, at the point of unloading and
these are preferably filled in by Fishery Officers
The ‘Fishing Activity Form’ is a very important element of the programme and
is used to estimate logbook coverage or to scale up the logbook data.
Length frequency sampling at a level of 5% (minimum) of all unloaded trips is
also recommended gives management data.
We have other small-scale vessels that don’t
regularly target pelagic species
• The artisanal tuna data collection programme is most compatible with
collecting catch and effort data from vessels targeting tuna / pelagics
• It can be used to collect data from other small scale fisheries
• However, challenges arise if the fishery your are sampling are dominated by
non-pelagic species.
• These challenges are less about the data collection forms (although there
may be some issues) and more in terms of funding support, reporting and
assigning staff.

Length Frequency Sampling – Artisanal Fishery
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
Indicates the total number of trips that have been carried out. Logbooks only
indicate the catch for one trip.
Similar to the ‘Fishing Activity Form’ provided to industry. It helps to gauge the
logsheet coverage (now VMS being used).
It can be difficult to implement this form, especially if you are aiming to trap
100% of trips.. It will depend on local conditions, no. of boats / no. Of fishery
officers etc. See manual...
3. The final use of the fish
The logsheet form does not capture the final use of fish (sold etc), since this is
not known at the point of unloading. Market Survey Data can be used to
capture the amount / value of fish that pass through the Fish Market.
(New Market Survey Manual being developed by CFP, SPC)
NEW ! Links with other data collection programmes
The same forms can be used to get data from other vessel based fisheries.
Using the same form across different fisheries will make things easier for staff,
data management etc.
 Deep Bottom Snapper Fishery
The Deep Water Snapper Workshop (July ‘11) suggested that the artisanal
tuna data forms are compatible with their data collection needs. This is
particularly helpful if fishers switch gears during the trip or during the season.
 Sports Fishing Vessels
The form will met the needs of data collection from sports fishing vessels.
(Note there are older DCC sport fishing forms available which include
competition forms).
 Creel Survey
The SPC Creel Survey Manual (now in testing phase) will probably use the
artisanal tuna form to capture catch and effort data.
The questions the data can answer
• Annual Catch Estimates
• Value of the fishery or contribution to GDP
• Effect of FAD deployment programme (catch rates, economics)
• Interactions between commercial and artisanal fishery
• Length based management of fishery.
• Contribution to regional stock assessments
National Sampling Design
• Consider: How many boats you have, their distribution and
what type of questions you want your data to answer.
• Decide on where the sampling will be done and what level
of sampling is required.
• Adhere to general principles of ‘random sampling’.
• A ‘snapshot’ or low frequency survey using the ‘Creel Survey
Manual’ may be more appropriate for countries with low
number of vessels, limited resources or for outer islands with
poor access.
• The final national sampling design maybe constrained by
resources (staff, transport, funds) and access to sites.
• Good data practice
Document your national sampling design and your data
collection and management procedures.
