1 December 2015 FishSource data source¶
Meeting Notes:
Topics: Fishsource (SFP) data contribution to BBAssessment GRSF
Participants: Aureliano Gentile (FAO, Moderator), Yannis Marketakis (FORTH), Anton Ellenbroek (FAO), Raul Vilela (FAO), Susana Segurado (FishSource - SFP), Merul Patel (FishSource - SFP)
Notes
- FishSource has about 2 500 profiles (public and draft, 1892 are public at 25 Jan 2016), 1 000 for marine resources, 1 500 for fisheries
- Marine resources are classified as follows: Stock - Assessment Unit - Uncertainty
- Fisheries are defined by : Gear, flag state, management unit (organizations)
- Species are based on ASFIS classification with rare exceptions, however ASFIS is not mandatory
- 1 single common name field
- A stock is associated to one or more management units
- Gear and Vessels are based on ISSCFG, ISSCFV classifications
- Stocks are described against time (time series of catches, biomass estimates, TAC, etc.), data points are time bounded
- Sources of information are usually provided, multiple sources are allowed for a single record.
- FishSource is relying upon public data
- FishSource Scores are based on proprietary algorithms and made publicly available
- The contents are stored in a postgreSQL database, for the moment without APIs for data exposure. YM asked for an API that will expose them in a standard way (i.e. REST). The FishSource team agreed that they'll do it.
Follow-up actions
- FishSource team to sent a dump containing some profile trees (in 2-3 weeks)
- FORTH to analyze and see how to support the integration of these data, with data from FIRMS and RAM
- FAO and FORTH to define exactly the contents that are going to be fetched from FishSource, so that the FishSource team will develop the corresponding APIs
Definitions
Assessment unit
Ideally, a biological stock is examined to determine the sustainability of a resource. Species may be assessed by units that are not aligned with the biological stock structure, either because the stock structure is unknown, or for practical or political purposes. Although not an ideal situation, the results can still provide valuable information on the species’ status.
Management system
One or more management systems may have jurisdiction over a resource, and thus the responsibility to regulate the fisheries conducted upon that resource. The management system may be the product of a national management authority or a regional or even smaller-scale authority or management instrument. Alternatively, two countries may agree to jointly manage a shared stock through a bilateral agreement, or multiple countries may have management responsibilities within an agreement such as a regional fishery management organization (RFMO).
Management unit
A management system may operate at the international, national, regional, or even smaller scale. One management system may manage the same species differently in different fishing areas. A management unit can thus take a diversity of forms but can be defined as the most basic unit wherein one or more management organizations, within a defined fishing area, distinctly manage a particular resource.
Fishery
The term “fishery” can have many different meanings. Within FishSource profiles, we use it to indicate the combination of a flag country with a fishing gear operating within a management unit, upon a resource. It is the finest scale of resolution captured in FishSource profiles, as it is generally the scale at which sustainability can most fairly and practically be evaluated with FishSource’s methodology.
