Operational Units : a preliminary study

1. Introduction

During the first session of the Scientific Advisory Committee (SAC), 27 provisional management units for small pelagic and shelf demersal species where broadly defined (App. 1). Whilst making every effort in keeping the existing GFCM statistical divisions (App. 2), the creation of the proposed management units was based on a number of criteria including, inter alia, continental shelf geography (App. 3), species distribution patterns (App. 4) and oceanographic features (App. 5 and 6). National management units for coastal resources established within limits of national jurisdiction were not considered and it was suggested that islands would constitute distinct management units.

It was envisaged that this arbitrary partitioning would be revised following further in-depth studies which needed to be carried out by the different Sub-Committees of the SAC in the future. In this respect, at the 24th session, the GFCM Steering Committee agreed that a number of working groups would be set up to examine the geographic coordinates of the proposed management units.

Under the general guidance of the Chairman of the SAC and supervision of the Co- ordinator of the Sub-Committee on Statistics and Information (SCSI), this preliminary study on “Operational Units” within the “Geographical Management Units” of the Western and Central Mediterranean regions was carried out. By using existing literature and data available at the FAO headquarters together with information from Fisheries Institutions and Research Centres in the countries concerned, the study focussed on the identification of Operational Units.

2. The definition for an “Operational Unit”

During a preliminary meeting1 held at FAO headquarters (December 1999) a number of possible definitions for an “Operational Unit” were discussed. The members at this meeting eventually agreed upon a definition, which seemed to be compatible with all disciplines concerned with fisheries management:

“An Operational Unit is composed of the same category of fishing vessels, operating in the same Management Unit, practising the same type of fishing operation and targeting the same group of species”Œ

An Operational Units would be a set of localised ones connected to different ports within the Management Unit.

1 S. Coppola, P. Oliver, I. De Leiva, R. Franchesa, M. Camilleri

In trying to find a universal definition for an “Operational Unit”, the major bottleneck was confronted when dealing with artisanal fisheries. From an economic point of view artisanal fisheries are considered to be one operational unit even if different types of fishing gear are used. In order to overcome this problem, the words "practising the same type of fishing operation" were used instead of "using the same type of fishing gear". Thus, artisanal fisheries could be considered to be one type of fishing operation.

This definition was reviewed at a follow-up meeting2 held in Barcelona (January 2000) where it was finally suggested that the definition for an “Operational Unit” should read as follows:

“For the sake of managing fishing effort within a Management Unit, an Operational Unit is the group of fishing vessels practising the same type of fishing operation, targeting the same species or group of species and presenting similar economic structure. The grouping of fishing vessels should not be understand as fixed over time, but be function of the management objectives to be reached”•

The second definition needs a few grammatical amendments, nevertheless, within the framework of this study a third definition is being proposed:

“An Operational Unit is a category of fishing vessels operating in the same Management Unit, practising the same type of fishing operation and targeting the same species or group of species”Ž

3. Literature and database review

Within the context of the proposed definition for an “Operational Unit”, information related to “stock concentrations” (Table I), species distribution and population dynamics for a number of species was gathered together with data on associated fisheries. The key sources used were the POPDYN database, ASFA, FAO (GFCM) documents, the Atlas of Italian Demersal Fishery Resources (GRUND) (Ardizzone and Corsi, 1997) and the Atlas of the Fisheries of the Western and Central Mediterranean (Charbonnier and Garcia, 1985). In order to be compatible with the studies which were being carried out by the Sub-Committee on Stock Assessment (SCSA), the species chosen in this study were the same as the ones focused on by the working group of the SCSA (see Appendix 7 for species information). Tables with the relevant information were drawn up by species and preliminary identification of Operational Units and / or areas hosting particular Operational Units was carried out (Tables II -VIII)3.

2 4. Data on fishing activities in various Management Units

Following the literature and database review, it was decided that visits should be made, in the first instance, to Fisheries Institutions / Laboratories in the Management Units of the Alboran Sea and Southern and Eastern Sicily (and Malta). It was agreed that these visits would serve to obtain more detailed qualitative (and possibly quantitative) data on fishing activities in these areas which would be essential for the eventual identification of Operational Units.

4.1 Mazara del Vallo (Istituto di Ricerche sulle Risorse Marine e l’Ambiente)

4.1.1 General information The fishing grounds in the Sicilian Channel (including Tunisian waters and Libyan waters) for various species or groups of species are well known and named. The number of boats operating in different areas of this region is also known, however, the fishing effort for particular species in each fishing ground is highly variable since the abundance fluctuates in short spaces of time and there is a shift in activity from one to another.

4.1.2 Identification of Operational Units In the light of the discussions held on the concept of Operational Units and the data available for this region, it was concluded that there are four different scenarios which should be considered: a) In many cases there is not enough evidence to consider a fishing ground as being the area occupied by the population of a particular species. Furthermore, due to the lack of data, the fishing grounds and / or species abundance concentrations cannot be aggregated into distinct areas hosting a number of operational units. Hence, an operational unit in such a situation, would only be a function of the group of the vessel, type of fishing operation and species / group of species i.e. without defining a particular area within the management unit. b) A few population dynamics studies have identified species “sub-stocks” in certain management units. Thus, if discrete fractions of a species or group of species live and are exploited in separate areas, they may be associated with different Operational Units.

Examples: (i) Parapenaeus longirostris in the Central Mediterranean (Fig. 1) Three different sub-stocks belonging to the same population in three distinct fishing grounds. Identification was based on length and maturity data. (Levi D., Andreoli M.G., Giusto R.M., 1994).

Areas hosting Operational Units: 1 area in management unit 1.3k 2 areas in management unit 2.2f

Figure 1. The three fishing grounds for Parapenaeus longirostris in the Sicilian Channel (Levi et al. 1995)

4 (ii) Aristeus antennatus in the Ionian Sea (Fig. 2) Populations in the three different fishing areas in the NW Ionian Sea have different length-frequency distributions, sex ratio, mating and size at first maturity. (G. D’Onghia, A. Tursi, P. Maiorano and M. Panza, 1998).

Areas hosting Operational Units: 3 areas in management unit 2.2c c) The same approach as described in (b) could be applied more confidently when dealing with genetically defined stocks within a region.

Example: Two stocks of Engraulis encrasicolus in Adriatic waters (Fig. 3a and 3b) Allozyme electrophoresis and morphometric analyses confirmed the genetic separation of two putative stocks; one located in the north-western Adriatic and the other in the central-southern region (D.G. Bembo, G.R. Carvalho, N. Cingolani, E. Arneri, G. Giannetti and T.J. Pitcher, 1996).

Areas hosting Operational Units: 1 area in management unit 2.2a 1 area in management unit 2.2b d) A few studies have suggested that the stock of a particular species extends over a vast area, consequently occupying more than one Management Unit.

Examples: (i) Hake in the Central Mediterranean (Fig. 4) A unique stock inhabits the vast area of the central Mediterranean between Sicily and Tunisia. Age-length study carried out using otoliths (D. Levi, M.G. Andreoli, E. Arneri, G. Giannetti and P. Rizzo, 1994).

Area hosting Operational Units: 1 area spread over management units 1.3k, 2.2e and 2.2f

(ii) Mullus barbatus in Tunisian waters 1 north eastern stock and 1 southern stock (Ben Mariem et al. 1995)

Areas hosting Operational Units: 1 area spread over management units 1.3k and 2.2f 1 area spread over management unit 2.2f

4.2 Fuengirola (Centro Oceanografico de Malaga)

The preliminary approach adopted in order to identify operational units was presented at the Oceanographic Institute in Fuengirola, Malaga. Experts working at the institute were invited to submit relevant information on the distribution of targeted species, on

4.2.1 General Information Statistics related to the number of fishing vessels by tonnage (range) and by port were readily available, together with landings and Catch Per Unit Effort by species, by month and by port from 1945 to 1997 (Giráldez Navas et al. 1999).

4.2.2 Identification of Operational Units There is no conclusive information to enable the identification of areas occupied by distinct populations of small pelagic species such as Sardina pilchardus i.e. it is likely that the same population is spread over a vast area (see Abad et al. 1998). Distinct fishing areas have yet to be defined. This case is similar to that described in 4.1.2a.

However, data exist for populations of Mullus barbatus and Mullus surmuletus, which suggest that the area they occupy is determined by the type of substrate and depth contours. Hence, this gives rise to another scenario, in addition to the ones described in 4.1.2, whereby the area hosting the operational units is determined by benthic physical characteristics.

Reference: Spatial segregation of two species of Mullidae (Mullus surmuletus and Mullus barbatus) in relation to habitat. (Lombarte A., Recasens L., Gonzalez M. and Gil de Sola L., 2000)

Summary: Mullus barbatus : 50m-200m; muddy bottom, wide shelf Occupying management units 1.1d, 1.1b, 1.1a

Mullus surmuletus : 10m-50m; rough bottom, narrow shelf Occupying management units 1.1d, 1.1b, 1.1a

5. Conclusion

The study has provided the basis for the eventual identification of Operational Units, however, the definition for an operational unit may need to be revised and areas hosting the operational units for different species have yet to be clearly established.

Nevertheless, within the context of the proposed definition, a few operational units could already be identified from the literature and database review carried out in this study. For example, in the case of Merluccius merluccius in the Gulf of Lions (Management Unit 1.2e) three Operational Units seem to exist: Operational Unit 1 – 170 French trawlers + 26 Spanish trawlers Operational Unit 2 – 20 French gillnet boats Operational Unit 3 – 13 French longliners

On the other hand, in the light of the scenarios described in Section 4, it is evident that the geographical limits for an Operational Unit are highly debatable. In many cases, it will be found that an Operational Unit is confined to a particular area within a

9 Management Unit or may even be associated with two or more Management Units. It is therefore recommended that areas occupied by distinct populations of various species are clearly established before an inventory of Operational Units could be formulated.
