The deepwater chondrichthyan fauna of the Great Barrier Reef is poorly known and life history information is required to enable their effective management as they are inherently vulnerable to exploitation. The chondrichthyan bycatch from the deepwater eastern king prawn fishery at the Swain Reefs in the southern Great Barrier Reef was examined to determine the species present and provide inform...

The impact of industrial fisheries on marine biodiversity is conspicuous in large pelagic vertebrate's bycatch. In seabirds, this led to the decline many populations since 1980s following rise global fishing effort. Bycatch mitigation measures were implemented 2000s, but their effects concerned seabird remain poorly quantified and understood. We studied bycatch demography white-chinned petrel, ...

Togok is one of the fishing gear that operated in Kuala Tungkal, Tanjung Jabung Barat Regency, this form a conical net body whose arms are tied to two poles and success catching it relies on currents, togok used by Tungkal fishermen catch rebon shrimp (Acetes japonicas) but operation, there many other types catch. This study aims determine main catch, bycatch, discards, size as well number catc...

One key issue for standardizing catch per unit effort (CPUE) of bycatch species is how to model observations of zero catch per fishing operation. Typically, the fraction of zero catches is high, and catch counts may be overdispersed. In this study, we develop a model selection andmultimodel inference approach to standardize CPUE in a case study of oceanic whitetip shark (Carcharhinus longimanus...

Abstract Diving is an ecologically important behaviour that provides air-breathing predators with opportunities to capture prey, but also increases their exposure incidental mortality (bycatch) in commercial fisheries. In this study, we characterised the diving of 26 individuals three species, black-browed albatross Thalassarche melanophris, grey-headed T. chrysostoma and light-mantled Phoebetr...

Abstract Bycatch continues to be a challenge sustainable fisheries management (The term “bycatch” in this paper covers discards and does not include retained incidental catch). estimates can inform stock status determinations by improving understanding of fishing mortality, help managers monitor the effectiveness regulations. Assessments quality bycatch estimation programs procedures are necess...

Bycatch of dolphins in inshore gillnets first attracted scientific and management attention New Zealand the 1980s. During 1984-88, 50-150 dusky were killed each year at Kaikoura set surface to catch bait for rock lobster. At same time, annual catches 20-100 Hector’s occurred Canterbury waters bottom-set commercial recreational gillnets. These resulted banning surface-set gillnetting 1989 creati...

Environmental DNA analysis is rapidly transforming biodiversity monitoring and bolstering conservation applications worldwide. This approach has been assisted by the development of metabarcoding PCR primers that are suited for detection a wide range taxa. However, little effort gone into exploring value non-target sequences generated in every survey, but subsequently discarded. Here we demonstr...
