| dc.description.abstract | In Tanzania, coral reef-associated elasmobranchii fisheries are among the most important as they contribute significantly in small-scale subsistence (artisanal) category in some cases representing the major income for many coastal communities. Tanzania's marine fisheries sector, especially in coral reefs’ associated elasmobrachs is constrained by lack of data on fish stocks, fishing effort, and level of exploitation. This study was conducted so as to characterize the catch composition for elasmobranchs in the selected hotspot landing sites in Tanzania mainland. Elasmobranchs landings from artisanal fisheries were observed from February to July, 2020 in the selected landing site. A total of 391 individuals of rays and sharks were recorded at the selected landing sites in Tanzania mainland during this study. The landed elasmobranch catches belonged to four families of Dasyatidae, Myliobatidae, Carcharhinidae and Sphyrinidae. At least eight species of elasmobranchs were recorded in this study. Species from Dasyatidae family dominated the total fish catch. The landed fish species were of small and medium size (cm), all immature. The occurrence of immature fish in the catch is an indicator of fishing overexploitation to take place along the Tanzania mainland coastline. | en_US |
