2 Regional Catch Effort data
The regional_ce database holds commercial catch effort data
provided from New Zealand vessels fishing on the high seas and
furnishing non-NZ Catch Effort forms. The regional_ce database
is required to store catch, effort, landings, processing and
environment information provided to the Ministry of Fisheries by
commercial fishers or their agents. Current data sets stored are
provided from the South Pacific Regional Purse-seine Fishery and
information collected under the Convention for the Conservation of
the Antarctic Marine Living Resources (CCAMLR) to aid in the
management of the Antarctic marine resources, provided from Bottom
Longline vessels fishing for toothfish.
Of these data:
Catch data are the catch (kg of each species) recorded by the
vessel as they fish.
Effort data summarise the amount of effort that a vessel put
into catching fish, including the method that was used, position,
date, times and the species targeted where applicable. The South
Pacific Regional Purse-seine does not record target species.
Landings data summarise either the actual quantity of fish
landed at a wharf (or transferred to another vessel at sea). South
Pacific Regional Purse-seine data only.
Environment data are provided only by CCAMLR and summarise
water depth and bottom type where fishing taking place.
Information is received from CCAMLR trips electronically,
currently as Microsoft Excel spreadsheets.
Information from the South Pacific
Regional Purse-seine fishers is supplied on several forms types:
South Pacific Regional Purse-seine
Logsheet This is a Catch Effort Landing Return for the fishery.
The form consists of a header section at the top for vessel and trip
details, a number of rows to record catch and effort information,
and a landings section in the lower part of the form. Generally only
one form type is used, except for a variation of the form when
fishing in Kiribati waters. A separate form is required for each
change in Fishing permit or licence number used.
Purse-seine Activity and catch report
form - Kiribati Waters This form is very similar to the first
one in appearance, with some slight variations in the data fields
collected, e.g.Effort includes Duration (hrs) and Aerial Search
The regional_ce database is designed to store these
different data sets in a central, managed Relational Data Base
Management System (RDBMS), as well as to provide the ability to
preemptively hold data from other regional fisheries that the
Research Provider may be required to maintain in future times.
