IOTC Statistical Data Reporting: Form 3CE (v1)

Description

This form provides for the reporting of estimates of geo-referenced species-specific catches and efforts by fishing fleet, fishery, and space and time strata.

Click here to download a blank version of Form 3CE, or return to the list of all new versions of the IOTC statistical data reporting forms. The form allows reporting updated data for multiple fisheries simultaneously. Click here to download a blank version of Form 3CE which has been designed to report updated data for a single fishery.

Data Content

Total number and/or live weight of retained catches by species and effort by stratum, along with information on the value (%) and type of sampling coverage used for the estimations by month, year, fleet, fishery, raising status, and fishing area.

Additional Information

Effort Units Recommended By Fishery

Effort units must be consistent with the recording requirements established in Res. 15/01 complemented by numbers of fishing operations for longline fisheries and surface fisheries (IOTC-2022-SC25-R). For coastal fisheries, it is recommended that effort data be submitted in the same units as those prescribed for longline fisheries and surface fisheries characterised by the same fishing gear.

Gear group	Primary effort	Secondary effort
Gillnets (GI)	Number of fishing days	Number of fishing operations
Hooks and lines (HL)	Number of fishing days	Number of fishing operations
Longlines (LL)	Number of hooks deployed	Number of fishing operations
Other gears (OT)	Number of days at sea	Number of active gears/fishing operations
Pole-and-lines (PL)	Number of fishing days	Number of fishing operations
Purse seines (PS)	Number of fishing hours	Number of fishing operations

From a general perspective, using trips as a unit of effort is not recommended because trip duration can vary widely due to factors such as vessel size, fishing success, and technical considerations (e.g., fuel availability).

Additional units may be considered to refine and standardise the estimation of nominal fishing effort:

1. In gillnet fisheries, the surface area of the nets deployed may better reflect effort intensity by accounting for differences in net length and height;

2. In hooks and line fisheries, the number of hooks may be used as required for longline fisheries;

3. In pole-and-line fisheries, the number of day-poles used may help account for differences in the number of fishers onboard the vessels;

4. In purse seine fisheries, the numbers of successful and null fishing operations, searching time, and surface area explored may complement the information provided by fishing time and the total number of fishing sets.

Other Dimensions

The spatial and temporal resolutions, catch units, and level of extrapolation vary according to the fishery category.

Category	Temporal resolution	Spatial resolution	Catch unit	Extrapolation
Surface fisheries	Month	1° grid area	Live weight equivalent	M
Longline fisheries	Month or finer for the SC	5° grid area or finer for the SC	Numbers or live weight equivalent	M
Coastal fisheries	Year or finer	Irregular areas	Numbers or live weight equivalent	O
