- Description
- Data extracted from a review paper on fisheries in Chagos._TABLE 1:_ Historical catch and effort data available for the BIOT inshore fishery, 1977 - 1990 (From Ardill, 1986; Samboo & Mauree, 1988; Kropelein,1979, and British High Commission, Mauritius, unpublished data relating to applications to fish, not necessarily the number of vessels in the zone)._TABLE 2:_ Historical details of licences issued and taken up, indicating the total effort of all vessels in the BIOT FCMZ, 1991-1997 (days in zone). A maximum of 6 licences may be utilised in any one year within the BIOT FCMZ. If a licence is not utilised within 30 days it becomes void, and a new licence may be issued to further applicants. Licences are not transferable._TABLE 3:_ Fishing locations within the Chagos Archipelago (refer to Figure 1 for location codes): reported area, and estimated sustainable yield per annum (tonnes) by depth stratum derived from a range of yields (t km-2) observed at similar locations in the Indian Ocean (Saunders, 1988; Mees, 1993)._TABLE 4:_ Dory landed catches by fishing location for the period 1991-1997. The proportion (%) of the catch derived from fishing on the banks is indicated in parentheses. Refer to Figure 1 for location codes._TABLE 5:_ Distribution of effort by location (refer to Figure 1 for location codes) for the BIOT inshore fishery, 1991-1997. The proportion (%) of the effort from fishing on the banks is indicated in parentheses._TABLE 6:_ Biological parameter estimates derived for Lethrinus mahsena caught at various locations (refer to Figure 1 for location codes) in Chagos during the period 1994-1997. Parameters indicating management concern are in bold (Source of growth parameter estimates a = Dalzell et al. 1992, Yemen; b = Bautil & Samboo, 1988, Mauritius; c = Otoliths from Chagos, Pilling, PhD thesis.)._TABLE 7: _Biological parameter estimates derived for Pristipomoides filamentosus, Aprion virescens, Variola louti and Pristipomoides multidens caught at various locations (refer to Figure 1 for location codes) in Chagos during the period 1994-1997. Parameters indicating management concern are in bold (P. filamentosus, Mees, 1993, Seychelles; A. virescens a = Van der Knapp et al. 1991, Maldives; b = Mees, 1992, Seychelles; c = Otoliths from Chagos, Pilling, PhD thesis, in prep. (note, Z may be low due to lack of small individuals in sample); V. louti, Munro & McB Williams, 1985, Papua new Guinea; P. multidens, Manooch, 1987, Australia)
