Fish personality traits, such as swimming activity, or personality related emergent behavioural properties, such as the degree of space use shown by an individual fish, should affect encounter rates between individual fish and fishing gear. Increased encounters should in turn drive vulnerability to capture by passively operated gears. However, empirical evidence documenting a relationship betwe...

The multi-gear coastal vessels in the Algarve (South Portugal) own licenses for various fishing gears. However, it is generally uncertain what gears they use, which problematic as each individual gear responsible unique impacts on resources and environment. In this study, landing profiles identified fleet (2012–2016) were used support defining potential métiers using k-mean clustering analysis ...

Abstract Comparisons between the implications of commercial and recreational fisheries for estuarine conservation have been a topic debate. A review on available data from Guaratuba Bay, Southern Brazil, identifies six threats conservation, other than those concerning fishing effort target resources. Differing popular view that pleasure could be innocuous environment, identified concern both no...

Fishing constitutes one of the most significant threats to marine biodiversity and ecosystem function, documented by a growing body of information on the numerous impacts to populations, community structure, and habitats (Dayton et al., 1995; Roberts, 1995; Jennings and Polunin, 1996). Besides the more obvious effects on species population structure, fishing activities may also reduce the struc...

Abstract The use of tracking devices, such as vessel monitoring systems or automatic identification system, enabled us to expand our knowledge on the distribution and quantification fishing activities. However, methods models based data are mostly devised be applied towed gears, whereas applications multi-gear passive fisheries have been underrepresented. Here, we propose a methodology deal wit...

Abandoned, lost, or otherwise discarded fishing gear (ALDFG) and ghost are becoming increasingly severe, hurting marine ecology inspiring worldwide concern. The Global Ghost Gears Initiative (GGGI) is committed to building a best practice framework for the management of believes that proper systematic marking will help mitigate impacts ALDFG fishing. However, mandatory fishery management, witho...

Fisheries bycatch continues to drive the decline of many threatened marine species such as seabirds, sharks, mammals and sea turtles. Management frameworks typically address incidental catch with fleet-level controls on fishing. Yet, individual operators differ in their fishing practices efficiency at catching fish. If have differing abilities target, they should also avoid bycatch. We analysed...

The mortalities and contributing parameters were estimated for key species discarded during commercial gillnetting (80-mm mesh) targeting dusky flathead Platycephalus fuscus in a southeastern Australian estuary. Bycatches (1470 individuals from 16 species over 11 deployments) were assessed for their immediate mortalities onboard the gillnetter, before subsamples (570 individuals from 11 species...

Fish landing activities in Sibolga Fishing Port are dominated by small pelagic fish, used purse seine. Purse seine is one of the most widely fishing gear Sibolga. The reason for large number gears because this considered to be quite effective use and also availability potential support it carrying out its operation. using methods aimed at schools fish. purpose study was determine specifications...
