    Spatial and temporal distribution of reef fish spawning aggregations in the Seychelles – an interview-based survey of artisanal fishers (2006)
    WIOMSA
    Details
    Publication Date: 2021-05-19
    Description: Many coral reef fish species aggregate at specific times and locations for the purpose of spawning. This study examined the spatial and temporal distribution of spawning aggregations in the Seychelles. An interview-based survey of the principal stakeholders, mainly artisanal fishers, yielded 89 reports of aggregation fishing for 26 demersal and semi-pelagic fish species. Grouper aggregations were largely concentrated in the outer coralline islands of the exclusive economic zone, whilst those of snappers and rabbitfishes were mainly reported from locations on the Seychelles Bank. The spatial patterns among fish families were attributed to a combination of differences in species abundance and distribution as well as variation in fishing effort. Spawning periodicity reported by fishers indicated that for snappers and rabbitfishes, the most activity occurred across a protracted period of October to April/May, with peaks in activity at either end of that period. Grouper spawning activity was concentrated in the northeast monsoon months of November to January. The findings of this study suggest that several spawning aggregations are targeted by fishers on a regular basis, a practice that constitutes a primary issue for artisanal fisheries research and management in the Seychelles.

    Spiny lobster fishery on the Mahe plateau November 2001 - January 2002 (2006)
    Victoria: Seychelles Fishing Authority
    Details
    Publication Date: 2021-05-19
    Description: The present report reviews the spiny lobster fishery on the Mahe Plateau for the 2001/2002 fishing season. The monitoring programme, set up in 1992, was continued this season to collect more information on the spiny lobster stock in order to improve and maintain proper management of this resource around the Mahe Plateau. For the 2001/2002 lobster fishing season, a total of 40 licenses were issued namely twenty seven on Mahe, five on Praslin and eight on La Digue. Similar to previous seasons, the most frequently used lobster fishing technique was snorkelling which involved 32 fishing units, whilst only four units used the trap method and one used both snorkelling and trap. For this three-month fishing season, a total of 5.5 tonnes of spiny lobsters were estimated to have been landed compared to 10.2 tonnes in 2000-2001 fishing season. Most landings were on Mahe, which accounted for 58.44 % of the total catch (3.214 tonnes) followed by Praslin with 13.89% (0.77 tonnes). Both La Digue and Silhouette groups had landings of 0.5 tonnes each. The month of November accounted for 1.36 tonnes, while 3.37 tonnes was landed in December and 0.81 tonnes in January. A total of 350 trips were undertaken equivalent to 803 man-trips for the season with 107 trips in November, 193 trips in December and 50 trips in January. The snorkelling and trap capture methods represented 96% and 4% of the total catch respectively. The catch rates represented by catch per unit effort(CPUE) throughout the season were as follows: - 12.75 kg/trip(November) - 17.49 kg/trip (December) - 16.35 kg/trip January). The main species targeted were: Homard Grosse Tete (Panuliruspenidilatus) Homard Rouge (Panulirus longipes) Homard Vert (Panulirus versicolor). The catch composition by fishing method was as follows: a.) Snorkelling: b.)Trap: Homard Grosse Tete: 65.68% Homard Grosse Tete: 14.21% Homard Rouge: 26.83% Homard Rouge: 85.79% Homard Vert: 7.07%

    Artisanal fishing boats in Seychelles (2013)
    Seychelles Fishing Authority | Victoria, Seychelles
    Details
    Publication Date: 2021-05-19
    Description: The results of a census of fishing boats on Mahe, Praslin and La Digue are presented. In total 437 boats were counted of which 278 were outboards with engine, 48 were open whaler, 35 were pirogues, 25 were lekonomi, 22 were schooners, 11 were semi-industrial so were lavenir, 12 were 'others', 8 were whaler with deck, 4 were nouvo lavenir and 3 were wooden boats without engines. The details are discussed to understand the characteristics of the artisanal fishing boats. An analysis of the historical data follows. The number of pirogues and schooners decreased from 1985 to 1995, whilst the numbers of whalers have increased. Outboards on the other hand had remained relatively stable. The changes in the number of boats are a result of interaction between the available near shore and offshore fishery resource and the development of commercial opportunities, social and economic constrains and the effects of the fisheries policies.

    Net fishing and its management in Seychelles (2005)
    Victoria : Seychelles Fishing Authority
    Details
    Publication Date: 2021-05-19
    Description: Net fishing is an important component of the artisanal fishery of the Seychelles. It is composed of beach seine, encircling and set gillnets. This report reviews net fishery and its impact on the environment and fish stocks and provides a framework for its management. There are no current management measures for the traditional net fisheries except that all nets above 50 metres requires a license with a lead seal bearing the licence number. Certain irresponsible uses of these nets have ben acknowledged, principally the 'Met outaz' fishing strategy, incidental catch of marine mammals and the presence of commercially important juvenile fish in the beach seine fishery. SFA has addresses these issues rationally and management options are explored followed by recommendations.
