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:

  1. 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.

  2. 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 (Y/N).

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.
