Abstract

The observation of ecosystems by Ifremer's Fisheries Information System (SIH) is based on a network of sea cruises. It aims to assess the state of stocks of the various species fished in France and Europe. It also enables the characterisation of the marine ecosystem in which the populations evolve.

23 scientific cruises take place each year at sea, enabling data to be collected for more than 30 years for the oldest. Thanks to the use of standardised fishing gear, the data acquired each year on board scientific vessels or professional fishing vessels contribute to the calculation of the index of abundance, with thousands of fish taken during timed trawls. The fish are measured and their age is assessed by measuring their otoliths (small bones located in the inner ear of the fish).

Statement

On each French coastline, the cruises at sea are governed by Ifremer's SIH (Système d'Informations Halieutiques) methodologies.

The fisheries observation cruises are conducted according to standardised observation protocols specific to each series and available online from the Archimer website, https://archimer.ifremer.fr/

Demersal resources and populations are monitored along the majority of coasts, with the exception of the Côte d'Azur and the western coast of Corsica, the latter two areas having a very narrow continental shelf.

At Ifremer, the first series of standardised observations began in the second half of the 1970s. Each cruise lasts from a few days to more than a month, depending on the objectives and the observation conditions.

The data made available on the SIH website are as follows:

15-10-1980 : Start of the data series for NURSE

03-02-1985 : Start of the data series for RESSGASC

11-01-1986 : Start of the data series for IBTS

30-09-1987 : Start of data series for EVHOE

04-10-1988 : Start of data series for CGFS

15-05-1994 : Start of the data series for MEDITS

18-09-1995 : Start of the data series for NOURSEIN

01-03-1996 : Start of the data series for PALOURDES-GM

03-10-2000 : Start of the data series for COPER

07-04-2006 : Start of the data series for LANGOLF

02-11-2007 : Start of the data series for ORHAGO

24-06-2014 : Start of the data series for BARGIP

15-09-2014 : Start of the data series for CAMANOC

08-06-2016 : Start of the data series for NOURDEM

26-06-2016 : Start of the data series for PELMED

29-06-2017 : Start of the data series for COMOR

25-09-2017 : Start of the data series for NOURMONT

31-08-2018 : Start of the data series for NOURMED

17-09-2018 : Start of the data series for NOURCANCHE

26-04-2019 : Start of the data series for PELGAS

09-09-2019 : Start of the data series for NURSE-COTIER

09-01-2020 : Start of the data series for Shrimp Stocks

The list is not exhaustive and the data are currently being integrated into the Harmonie database.

The fisheries monitoring cruises conducted by Ifremer fall into five categories:

- bottom trawling surveys with large vertical openings, intended to observe resources and communities on the plateaus and upper slopes: IBTS, CGFS, EVHOE, MEDITS

- cruises to assess large crustaceans, in particular lobster (trap sampling): CRUSTAFLAM

- cruises targeting benthic species such as scallops (dredging campaigns), clams (Hamon grab in very coastal areas) or juvenile flatfish (beam trawl in very coastal areas): NOURSOM, NOURSEINE, NOURMONT, NOURMANCHE, COMOR, COSB, COPER or shrimps (Guyana)

- cruises targeting small pelagic fish (acoustic and trawling): PELGAS and PELMED

• Sampling plan(s) :

Random, stratified

• Precision of data type :

Index of abundance of fish species and major commercial invertebrates; Fine biological data per individual; Egg and larval data of small pelagics; Radial acoustic survey

• Parameter(s) observed or measured :

Specific and size composition of catches; Individual measurements (size, sex, maturity); Collection of pieces for ageing

• Resolution of parameter(s) :

By fishing operation, continuous survey (CUPES), systematic analysis of scientific fishing catches

• Format(s) :

The available data exist in the format: csv.
