1-RC form metadata

Retained Catches: 

Definition: The term Annual catches refers to highly aggregated statistics for each species estimated per fleet, gear and year for a large area (IOTC Area). 
These include: Retained and Discarded catches.

·         Retained catches: Refers to the part of the catch that is retained on board, expressed in live weight; it includes:

o    Catches of specimens of the target species, which are usually stored on the main vessel compartments and sold in the local market or other international markets.

o    Retained bycatch, which refers to the incidental catches of specimens of species that are not the target of the fishery but are of commercial value or to the catches of specimens of the target species having poor quality (e.g. undersized, spoiled, etc.).  Retained bycatch specimens are usually stored on separate compartments onboard and sold in the local markets or used for direct consumption.

 IOTC Form: Form 1RC

Structure of the form:

ReadMe: links to all code lists required for filling-up the forms.

NC: The main form to complete the retain catch

General Information:

·         Reporting Source: details about the individual reporting the information and the Institution responsible for the report.

a.       Contact name: Name of the individual reporting the information

b.      Contact e-mail address: E-mail of the individual reporting the information

c.       Contact phone: Phone number of the individual reporting the information

d.      Organization name: Name of the organization responsible for the report

e.       Organization e-mail address: E-mail of the organization responsible for the report

·         Dataset:  General information about the dataset reported.

a.       Reporting Country: The country reporting the catches (code list: FLG)

b.      Flag Country: The country for which retained catches are reported (code list: FLG)

c.       Year: The calendar year the catches were made

d.      Quarter: The standard calendar quarter of the year the catches were made

e.       Catch units: Retained catches shall be reported in live weight (metric tons)

Data:

·        Type of Fishery: The type of fishery for which the retained catches are reported (code list: FIS) 
·        IOTC Area: The IOTC Area in which the catches are taken (code list: ARE) 

·         Type of data: Type of statistics reported.

a.       Preliminary statistics: The catches were estimated by using some information from the fishery; the catches reported are likely to change in the future as more information become available.

b.      Final statistics: The catches were estimated by using the complete set of data for the fishery and year concerned; the catches reported are unlikely to change in the future.

·         Data Sources: The types of information that were used for the estimation of the catches retained on board for the fishery concerned (Code list: DSO)

·         Data Processing: The type of estimation procedure (code list: DPR)

·         Coverage: The proportion of the total catches that were monitored (sampled, in number or weight) for the fishery concerned (code list: COV).

·         Target species: Main species targeted by the fisheries. (Code list: SPC)

·        Catches by species: catches for each species retained on board in live weight by flag, type of fishery and IOTC Area. The catches of specimens for which only part/s of their bodies are retained on board shall be always reported as retained catches, in live weight. (Code list: SPC)
