Sharks are commonly caught in Indonesian waters both by target fisheries and as bycatch. Fishers targeting
sharks mostly employ drift longlines, whereas tuna longlines and gillnets are the gear mostly responsible for shark bycatch. Our studies on shark fisheries have been conducted since 2006 and have focused on the eastern Indian Ocean region, the...
The brown-banded bamboo shark, Chiloscyllium punctatum, is one of the most common sharks caught in coastal fisheries across Southeast Asia; however, its small size and low economic value typically exclude it from the attention of fisheries managers. As part of an assessment of a potential role for this shark in improving the sustainability of coast...
The brown-banded bamboo shark, Chiloscyllium punctatum is one of the most common shark species caught in coastal fisheries throughout the Indo-Malay region and the most abundant shark caught in trawl fisheries in Malaysia and Thailand. Differences in fisheries regulations related to trawling among jurisdictions, and an absence of either stock asses...
Background
Delimiting cryptic species in elasmobranchs is a major challenge in modern taxonomy due the lack of available phenotypic features. Employing stand-alone genetics in splitting a cryptic species may prove problematic for further studies and for implementing conservation management. In this study, we examined mitochondrial DNA and genome-wi...
