1. During 1989 an estimated total of 4,391.7mt of fish was landed on Mahe, Praslin and La Digue by 390 fishing boats, (including sport fishing boats), 81.2% of which was landed on Mahe alone. The volume of catch does not differ significantly from 1988, but the number of boats has decreased, being a decrease in the number of small boats and schooners, whilst whalers using handlines have increased. 2. The most important species groups landed (greater than 5% of the total catch) were carangues (32.0%), job (9.6%), red snapper (9.1%), capitaine (7.0%), maquereau doux (6.7%), and trap fishes (cordonier 5.6%, others 5.0%), and bonite (5.3%). 3. The variation in monthly landings was not as pronounced as in previous years. Peak landings occurred in April (430.1mt), May (446.6mt) and November (471.7mt). The lowest catch was recorded during July (263.4mt), during the period of S.E trade winds. The average catch per month was 366mt. 4. Species variation in the catch was apparent with pelagic fish (including bonite) tending to represent a greater proportion of the catch during the period of S.E Trades (May-September); and demersal fish (red snapper, vieilles, and to a lesser extent, job) being greater during the period January - May and October - December. Carangues were greater in the catch during April - June and November. Trap fishes did not show much variation but tended to be greater during January - February and August - October, capitaines peaked in the catch between July and September, whilst maquereaux were caught in the early and latter parts of the year with a distinct peak in September. Much of the variation observed, particularly the inverse relationship exhibited by pelagic and demersal fish may not represent seasonal variations in catchability of the fish, but rather changing fishing strategies during the different monsoon periods. 5. By landing site, Victoria was the single most important site accounting for 37.6% of the total. Other important sites were: Anse Royale Market (7.3%), Belombre (6.9%), and Anse Boileau (3.9%) on Mahe; Baie St. Anne/Cap Samy (4.0%) and Flying Dutchman/Grand Anse (3.5%) on Praslin, and on La Digue, La Passe (2.6%). Whalers accounted for a large part of this catch, and considering the small boats only (on foot, pirogues, outboards) the most important sites were Belombre (7.4% of small boat catch), Bougainville (6.6%), Pointe Conan (5.8%) Glacis (4.6%), La Retraite (4.5%) and Anse Aux Pins (4.2%) on Mahe, whilst on Praslin and La Digue where there are fewer whalers the rank order of importance does not change. 6. Trap fishes dominate the catch on Praslin and La Digue whilst carangue are most important on Mahe. This reflect the predominance of the small-boat fishery on Praslin and La Digue. 7. In total, the small-boat fishery accounted for 39.5% of fish landings during 1990: fishermen on foot, 0.6%; pirogues, 5.3%; outboards, 33.1%; whalers with traps, 0.5%. Fishermen on foot landed mostly octopus (72.9% of landings); pirogues landed trap fishes (43.7%) and maquereaux (21.1%); outboards landed maquereaux (32.1%), trap fishes (23.2%) and carangues (19.1%) whilst whalers with traps landed almost entirely trap fish (81.0%). Demersal fish formed only a minor part of the landings by the small boat fishery. 8. The whaler-handline fishery accounted for 46% of total landings. An average of 78 whalers operated each month during 1989 showing an increase of 13 boats since1988, whilst the catch landed was slightly less than 1988. Carangues accounted for the largest part of the landings (42.6%). Other important species were job (10.9%), red Snapper (10.0%), other carangues (9.6%), bonite (7.6%), capitaine (5.5%) and becune (5.5%). 9. An average of 16.2 schooners operated each month during 1989 and accounted for 14.2% of total landings. Although the number of boats decreased by 4.8 on average, the catch was significantly greater than during 1988. Bourgeois was the single most important species caught (19.0%) followed by job jaune (16.0%), job gris (8.9%), lascar (7.8%), vara vara (7.5%), vieille maconde (6.7%) and vieille platte (5.1%). The spanner crab, Ranina ranina accounted for 2.8% of schooner landings. The larger proportion of the catch landed by schooners during 1989 may reflect the use of electric reels on some boats, increasing their efficiency. 10. An average of 4 sport fishing boats accounted for 0.3% of total landings. Bonite (43.1%), sailfish (37.8%), wahoo (8.9%) and dorade (5.1%) were the most important species. 11. Fish purchases from the Artisanal Fishery by Seychelles Marketing Board (SMB) were equivalent to 29.8% of total landings (1308.7 mt). 67.5% was purchased through the 8 SM8 centres on Mahe and 32.5% through the 3 centres on Praslin and La Digue. Victoria was the single most important centre (50.4% of all purchases), followed by Anse La Mouche (9.2%) on Mahe. The Baie St Anne (12.1%) and La Passe (13.4%) centres on Praslin and La Digue respectively also accounted for a substantial volume of purchases. The least important centre was Cascade (0.2%), that at La Retraite already having ceased to function. The major species purchased were job (20.9%), red snappers (18.9%), vieille (14.7%), capitaines (8.8%) and carangues (8.7%). 12. S.M.B also purchased 272.6 mt of frozen fish (gutted and ungutted) from foreign longline vessels during 1989. Species purchased were all pelagic of which yellowfin was the most common (38.2%), followed by sailfish (18.8%), kingfish (5.7%) and marlin (5.5%). 13. Total exports (excluding tuna transhipped through Seychelles or through the cannery) amounted to 707 mt, 37% being fresh and 63% frozen, valued at SER 14.2 million (CIF). This represent an increase of 132.4 mt since 1988. Major destinations for the fish were Reunion (79.3%), England (10.4%), and France (2.9%). Job (25.6%), red snapper (24.1%), and maconde (19.1%) formed the most important fresh fish exports, whilst red snapper (31.0%), job (20.5%), and capitaine (20.4%) were the important frozen fish species. 14. A comparison of data collected between 1985 and 1989 follow. Data prior to 1985 are reported in the Artisanal Fisheries Statistics for 1985.
