MeetingBillfish caught in the recreational and sport fishing of south coast of Mozambique: Results of the first census of recreational and sport fishing in 2007 and the sampling program in 2012 2013
Also available in:
No results found.Despite recreatiol fishery in Mozambique has been practiced in different modalities, ranging from shore (without boat) to offshore boat based, it was found billfish only in offshore boat based recreatiol fisheries. These fishes are caught either in recreatiol fishery for leisure or within the fishery competition (sport fishery). In both modalities (offshore recreatiol and sport) the gear used to target billfish is hook and line operated with a fishing rod and manual reel. In these fisheries the billfish represent the trophy and the specimens are usually released alive. The results of the first census of recreatiol fisheries in south cost of Mozambique performed in 2007 revealed that billfish was one of the main target groups in recreatiol fisheries, together with Narrow-barred Spanish mackerel, yellowfin tu and other tropical tus. According with the census the main representative billfish species in south coast was the indo-pacific sailfish, but in the subsequent years the monitoring p rogram revealed that black marlin is equally and even more represented in the catches of sport fisheries. In 2012, it was estimated billfish to represent 12% of the total catch in weight of sport fishery. The species of billfish recorded was black marlin with an estimated number of ten individuals captured. The lengths of the specimens ranged from 280 to 350 cm. There was no catches of billfish recorded in offshore recreatiol fishery for leisure. -
MeetingShark bycatch - small scale tuna fishery interactions along the Kenyan coast 2013
Also available in:
No results found.In Kenya and to a great extent most parts of the WIO region, shark catches majorly occur as by-catch in artisal tu fisheries and prawn trawls, including sport fishing activities. However, the extent to which these various fisheries catch sharks is not known but may be significant. The species structure, distribution, catch rates and levels of fisheries-shark interactions are not well documented. This information is, however, necessary to assess exploitation levels of shark species and for settin g regulatory, conservation and magement frameworks. This study therefore aimed at filling this information gap. Data was collected from fisher landings at various sites along the Kenya coast and by observers on commercial and scientific trawl surveys. Landings at 5 beaches were inspected for 15 days per month for 12 months (August 2012 to July 2013). Specimens were identified to species and, sex, length and weight recorded for each shark landed or trawled as by-catch. Results indicate that the a rtisal and the prawn trawl shark bycatch is domited by Hammerhead sharks (Sphyr lewini, 53.7%), Blacktip Reef shark (Carcharhinus melanopterus, 33.7%), and Grey Reef shark (Carcharhinus amblyrhynchos, 5.5%). Other species present in the catches in lower quantities (~7.1%) include Carcharhinus falciformis, Carcharhinus longimanus, Carcharhinus brevipin, Sphyr zygae, Stegostoma fasciatum. Catch rates of species show spatial and seasol variation in abundance with higher catches in Kenya’s north coa st. Morphometrics of the domint species are included, and size- frequency distributions show mostly juveniles in the catches. There is need to continuously monitor the distribution and abundance of sharks, including shark-fishery interactions in the WIO region for purposes of conservation. -
