Provides information on Stocks with no nested Assessment Units, Unascertained, and all Assessment Units (whether they are top nodes or children nodes) that are not Salmon related. Draft information is not returned by this endpoint.
The response is an array of JSON objects, each summarising information about a single Fishery Profile tree.
As the number of data points can be quite large, the response doesn’t contain any quantitative data associated with the Fishery Profile tree, but this can be fetched using the DATA endpoint.
| Element | Description (Root) | Description (Child) |
|---|---|---|
| id | The internal FishSource identifier for the Stock, AssessmentUnit or Unascertained node at the root of the Fishery Profile Tree | The internal FishSource identifier for the AssessmentUnit child node in the Fishery Profile Tree |
| name | The name of the root node prefixed by the Species FAO name or first common name. This is the same as the name shown on the FishSource website. | The name of the child node prefixed by the Species FAO name or first common name. |
| type | Indicates whether the root of the Fishery Profile Tree is a Stock, AssessmentUnit or Unascertained | Indicates the Fishery Profile Tree type. For child node, the type will always shown as AssessmentUnit since Stock and Unascertained are only available for the root node. |
| node_type | Indicates the type of the Fishery Profile node level. Root type indicates that the Fishery Profile is on the top level of the Fishery Profile Tree structure. | Indicates the type of the Fishery Profile node level. Child type indicates that the Fishery Profile is on the second tier of the Fishery Profile Tree structure. |
| grsf_type | Indicates the Fishery Profile type based on the GRSF classification. There are 2 types of GRSF classification: 1. Assessment Unit Fishery Profile of type: Stock with no nested Assessment Unit OR Fishery Profile of type: AssessmentUnit will be classified in this grsf_type.2. Marine Resource Fishery Profile of type: Unascertained will be classified in this grsf_type. |

| state_of_marine_resource | An array of narrative text (XHTML) associated with the root node of the Profile Tree related to the Current Status as shown on FishSource. Each array element contains both the narrative text as well as the internal FishSource identifier for the node in the Fishery Profile Tree associated with the text, and also the date of the most recent citation in the text | An array of narrative text (XHTML) associated with the root and child node of the Profile Tree related to the Current Status as shown on FishSource. Each array element contains both the narrative text as well as the internal FishSource identifier for the node in the Fishery Profile Tree associated with the text, and also the date of the most recent citation in the text |
| scientific_advice | An array of narrative text (XHTML) associated with the root node of the Profile Tree related to the Scientific Advice as shown on FishSource. Each array element contains both the narrative text as well as the internal FishSource identifier for the node in the Fishery Profile Tree associated with the text, and also the date of the most recent citation in the text | An array of narrative text (XHTML) associated with the root and child node of the Profile Tree related to the Scientific Advice as shown on FishSource.

"text": "<p>The maturing component, assessed in autumn 2016, was estimated at 181,000 t, below B<sub>lim</sub> . Due to low recruitment, it was expected that the maturing biomass would be well below B<sub>lim</sub> by ~163,000 t for 2017. However, the 2017 survey changed this and resulted in a much higher estimate than expected (1,723,000 t). This was due to the problematic estimates of the acoustic survey in 2015 and 2016.</p>
<p>In 2018 the results and analysis of that year’s survey indicated that the stock had a greater than 5% probability of being below B<sub>lim</sub> . As such the advice given by ICES was to have no fishery (zero catch) given that the stock has declined by ~39% since the 2017 assessment . Recruitment, as seen by the survey continues to be low, but the 2018 survey may have missed some of the recruits, which would affect the fishery in 2020 .</p>
<p>Fishing mortality cannot be determined and is not relevant for the management of the stock due to capelin’s semelparity (single spawning in its lifetime) and the nature of the fishery.</p>",

In 2015 the JNRFC asked that three Harvest Control Rules be evaluated by ICES setting the setting P(SSB < 200 000 t) to 90%, 85%, and 80%, respectively. ICES found that only the current rule was precautionary, and so the Harvest Control Rule will not be evaluated again until 2021 .</p>
