- 4.1.5.2.Fisheries data recorded by observers
4.1.5.Observer data4.1.5.1.Observer activityIn the past there was some scientific observation of deep-water fishing. These were carried out for scientific projects, aims could be be collection of biological data, including the distribution and habitat of species. Several fishing trip were observed to analyse the abundance, distribution and reproductive strategy of sikis sharks (Girard 2000). Similarly, Allain (1999) observed a number of fishing trips in 1996-97 to collect biological data and samples on several species and also analysed the discards of the deep-water fishery (Allain et al. 2003). In the 2000, sampling plan for on-board observations were developed in application of the data collection framework (Decision from the commission of 6 November 2008) and regulation (EC) N°2347/2002. Data from the application of these two regulations are fully availably in national databases and data from Allain (1999° were made available to the project. Table 4.1.5.1 Observer data available in Franch national databases
(1): data collected by Girard (2) collected by Allain, available to DEEPFISHMAN, not transferred to COST format (4) merged into data collected for Compliance with EC regulation 2347/2002 Data were available to stock assessment and, the quantities and length distribution of the discards on roundnose grenadier were included in the stock assessment in 2008 (ICES, 2008). For the other main deepwater species exploited by the French fleet the on-board observations only confirmed that discards were minor and had no impact on assessment. It was always known that this fishery did not catch significant amount of small black scabbardfish, blue ling and siki sharks, simply because small individuals of these species do not occur on the fishing grounds. The situation is more complex for orange roughy where small fish may be caught. However, due to the high value of this species, only very small individuals would be discarded. The on-boards observations also confirmed that the main species in the discards were smoothhheads, mainly Alepocephalus bairdi, which forms a high proportion of the biomass by 1000-1400 m, is discarded in large quantities. 4.1.5.2.Fisheries data recorded by observers[4.1.4.2 Fisheries data recorded by observers: please complete yes/no and cite time-series in the cells in the table below. Please append all available time-series data disaggregated by fleet ID if possible.:-] The specification on fishery data to record by observers are available on the webpage: http://www.ifremer.fr/sih/affichagePageStatique.do?page=collecte_donnees/observations_mer/documentation/documentation_obsmer.htm This documentation is in French. It includes general protocole and guidelines for all on-board observations and specific guidelines for some fisheries including deep-water fisheries. A number of tools useful to observers are also made available on the same page. The table 4.1.5.2 is filled in according to protocols from this webpage. Since 2010, data are organised under COST format (Jansen et al. 2009). data from Allain (1999) are organised under a different format and will be provided to the project with relevant metadata. Table 4.1.5.2. Data collected by on-board observed on French deep-water fishing vessels
Until 2010, the forms and database for on-board observations did not included section for VMEs, the protocole for deep-water fishery specified that this data should be reported as comment for every fishing tow or set. From 2010, the protocole requires that catch of live corals and sponges are reported together with discards species. This is in line with the NEAFC Recommendation XI: 2010, that catch of live coral over 60 kg and catch of live sponges over 800 kg should be reported by deep-water fishing vessels. Note that, in on-board observation catch of live coral and sponges of any weight will be reported while the requrement from identification of VMEs rely upon some threshold catch (to be specified in ICES advices 2010).
