Characterization of Beach Seine Fishing in the Mandji-Etimboué Aquatic Reserve (Gabon)

Caractérisation de la pêche à la senne de plage dans la Réserve Aquatique de Mandji-Etimboué (Gabon)

Abstract / Résumé

EN – The conservation of marine biodiversity and the establishment of aquatic protected areas have become a global challenge. Thus, the continued use of non-selective fishing gear requires a comprehensive and ongoing assessment. With this in mind, the catch rates and socio-economic aspects of beach seine fishing in the Mandji-Etimboué Aquatic Reserve (AR) were examined using landing monitoring as a methodological approach. The results showed that the average catch per unit effort (CPUE) of beach purse seiners is 393.29 kg/seine haul. Comparative analysis between CPUE in 2017 and 2021 showed a decrease of 490.9 kg/fishing trip in the rainy season and an increase of 5.08 kg/fishing trip in the dry season. The decrease in fishing effort and increase in CPUE in this Mandji-Etimboué beach seine fishery shows that fishery resources in the reserve are in good health. However, close collaboration between local communities and administrations is needed.

FR – La conservation de la biodiversité marine et la mise en place des aires protégées aquatiques sont devenues un défi planétaire. Ainsi, l'utilisation continue d’engins de pêche non sélectifs nécessite une évaluation complète et continue. Dans cette optique, les taux de capture et les aspects socio-économiques de la pêche à la senne de plage dans la Réserve Aquatique (RA) de Mandji-Etimboué ont été examinés en utilisant un suivi de débarquement comme approche méthodologique. Les résultats ont montré que les prises par unité d'effort moyenne (CPUE) des senneurs de plage sont de 393,29 kg/coup de senne. L’analyse comparative entre les CPUE de 2017 et 2021 a montré une diminution de 490,9 kg/sortie de pêche en saison des pluies et une augmentation de 5,08 kg/sortie de pêche en saison sèche. La diminution de l’effort de pêche et l’augmentation du CPUE dans cette pêcherie de Mandji-Etimboué montrent que les ressources halieutiques de la réserve sont en bonne santé. Toutefois, une collaboration étroite entre les communautés locales et les administrations est nécessaire.

The Plateaux Batéké National Park now boasts four cat species, thanks to the return of the lion to Gabon

English Since the return of a single male lion to Gabon’s Plateaux Batéké National Park, this park now harbours four species of wild felids; more than any other park within Central Africa’s Congo Basin. Besides the lion ( Panthera leo ), the park is home to important populations of leopards ( Panthera pardus ), African golden cats ( Caracal aurata ), and Gabon’s only protected population of the serval ( Caracal serval ). Servals are open habitat specialists which mainly feed on small rodents. The species is most easily recognized by its long legs, short tail and large, rounded ears. Commonly, the medium-sized serval is boldly spotted black on a tawny underground. There are also melanistic individuals in certain areas, which appear completely black. Even rarer, is the so-called ‘servaline’ form, which has much smaller, freckled spots, and was once thought to be a separate species. All three forms have been filmed in and around Plateaux Batéké National Park, making this the only ...

  Length-weight relationships of 13 fish species from Akanda National Park in Gabon, Central Africa English This study provides the length-weight relationships (LWRs) for 13 fish species belonging to 10 families. Samples were collected in the mangrove area of Akanda National Park (ANP) in Gabon between May 2017 and March 2018 with fishing trammel gillnets (15 m long and 1.10 m high, 100 mm large mesh outer layers, and one 10, 27, and 40 mm small mesh each net). Fish total length and total weight were measured, with the precision of 1 mm and 1 g, respectively. The LWRs parameters for the 13 fish species had not yet been reported in FishBase for Central Africa. Our study provides large size ranges for  Monodactylus sebae  and  Pseudotolithus senegalensis  LWRs for Central Africa. The determination coefficient (r²) between total length and total body weight ranged from 0.946 ( Pellonula leonensis ) to 0.999 ( Pseudotolithus senegalensi...

Real-time alerts from AI-enabled camera traps using the Iridium satellite network : A case-study in Gabon, Central Africa.

By -
  English Gabon, a Central African country, has long proven to be a fruitful testing ground for camera trap technology. The wealth of data generated means that there are large datasets from various projects. In this study, they built the real-time alert system by modifying standard camera traps (Bushnell™) ready to use. The system uses communication through the Iridium satellite network, it works even in remote areas without a telephone signal or without reliable Wi-Fi. The results show that the alert system can work for at least 3 months in the absence of humans when capturing a median of 17.23 images per day. The median time difference between taking images and receiving an alert was about 7,35 min, although some outliers showed delays of 5 days or more when the system was incorrectly installed initially and unable to connect to the Iridium satellite network. These models of artificial intelligence and the addition of other sensors such as microphones will expand the potential of...
