A reduction in catch per unit effort (CPUE) and fishing mortality were also observed (Giussi & Wöhler, 2010a).TrendsLast updated on 02 Dec 2011 Past trends in spawning biomass show a steep decrease from a level of over one million tonnes in the early 1990s to just over 400,000 tonnes in 2004, followed by a more gradual decrease which reached a minimum of 360,000 tonnes in 2006. Catch rates have been steadily decreasing since 1990, but fishing mortality and exploitation rates have remained quite stable over the years, only recently indicating a slight decrease (Giussi & Wöhler, 2010a).",

This catch strategy was expected to maintain the spawning biomass observed in 2009 and also maintain recent catch levels (Giussi & Wöhler, 2010a).\nThe South Atlantic Fisheries Commission previously provided advice on the stock. At present, the Falklands Fisheries Department has advised that the spawning season closure be maintained (Falkland Islands Government, 2011).Reference PointsLast updated on 02 Dec 2011 A limit reference point of 500,000 tonnes for spawning biomass was defined in the most recent assessment, based on the level needed to produce recruitment above recent averages (Giussi & Wöhler, 2010a). This was previously estimated as 600,000 tonnes (Giussi et al., 2007). No management reference points are known.",

The type of a stock record is assigned after they are harvested and transformed. Whenever a stock assessment is conducted then, the record is identified as an assessment unit.

Under this light, I see that there are many stock records that should be assessment units in GRSF_Admin VRE. I will update them accordingly.

Changed the type of 130 records to Assessment Unit.
The URLs of the records that have been updated is attached.

We have found another record that is an assessment unit in FishSource but a marine resource in GRSF: http://data.d4science.org/ctlg/GRSF_Admin/0dcd3d3d-bfa0-32b1-9372-88082d721b54

Aureliano, can you please clarify if it is a similar issue as above, or if this case is different because there are two sources (FIRMS and FishSource)?

Also, we are not understanding why there is no suggested merge between the FIRMS and FS records, but instead they are both identified as sources?

WRT comment 8, the API is definitely returning the root record as an 'AssessmentUnit':

Starting that year, there was a fast increase of the catches, which reached a peak of 6 509 301 t in 1985, in correspondence of the dramatic decrease of catches of the Peruvian anchovy due to El Niño phenomenon. Since 1985, the total catch is strongly decreased totalizing 1 503 131 t in 1995, mostly from Peru. Caught with purse seines ("small pelagic purse seining").

Thank you, Yannis.
Both examples shown in note #10 above are Stocks/AssessmentUnits in FishSource, therefore should not be ManagamentUnits in GRSF.
Assigning the ticket to Aureliano.

Marina

I've reviewed #13334, and am attaching a CSV file with the key fields from all FishSource StockOrAssessmentUnit records where the type is 'AssessmentUnit'. The parent_id field will indicate whether the AssessmentUnit is nested, but based on the notes in ticket #13334, this is not actually relevant.

I hope this is what you wanted, but if not, please advise.

Thanks Merul for the list.
Attached you will find the list updated with information from the GRSF KB. More specifically, you will find 2 more columns; one indicating if the records exists in the GRSF KB and has been published in GRSF, and one indicating the type of the record in GRSF.

You'll notice that:

• There are some records that do not exist in GRSF. This is normal for records created after March 2018 (This is the last time we harvested from FishSource and constructed GRSF from scratch). For the rest of them (e.g. with ids 764, 834, etc.) although they seem to be created earlier than March 2018, they do not exist in the harvesting of that period.
• There are 51 records that appear as Marine Resources in GRSF KB. If we all agree (@aureliano.gentile@fao.org let me know what you think) we can proceed with their update in GRSF KB (i.e. make them assessment units) and update them in GRSF VREs.
