The complexity of the ocean ecosystem, including the human component, is such that a single fishery may require multiple policy instruments to support recovery and conservation of protected species, in addition to those for fisheries management. As regulations multiply, the need for retrospective analysis and evaluation grows in order to inform future policy. To accurately evaluate policy instr...

Life history traits of wild animals can be strongly influenced, both phenotypically and evolutionarily, by hunting and fishing. However, few studies have quantified fishery selection over long time periods. We used 57 years of catch and escapement data to document the magnitude of and trends in gillnet selection on age and size at maturity of a commercially and biologically important sockeye sa...

Article history: Received 1 December 2003 Received in revised form 28 September 2005 Accepted 29 September 2005 Available online 27 December 2005 This paper considers the connection between the diversity of catch in amulti-species fishery and the productivity of the fishery under different access regimes. A modified Gordon– Schaefer model is used to analyse the importance of the level of divers...

Spatial and temporal trends and variation in life-history traits, including age and length at maturation, can be influenced by environmental and anthropogenic processes, including size-selective exploitation. Spawning adults in many wild Alaskan sockeye salmon populations have become shorter at a given age over the past half-century, but their age composition has not changed. These fish have be...

Although some sea turtle populations are showing encouraging signs of recovery, others continue to decline. Reversing population declines requires an understanding of the primary factor(s) that underlie this persistent demographic trend. The list of putative factors includes direct turtle and egg harvest, egg predation, loss or degradation of nesting beach habitat, fisheries bycatch, pollution,...

Artisanal fishing is an important traditional activity on the coast of Espí­­rito Santo (ES) State, southeastern Brazil. Despite this, there a lack updated data artisanal and its interfaces with socioenvironmental oceanography. The present study describes social profile fishers (gender, age, education, period professional activity) (fishing gear target species) along State. Interviews semi-stru...

The needlefish both full beak and halfbeaks support a good fishery in Tamil Nadu exploited by drift gillnet (Mural valai). In this study, we were focused to document the conversion of Mini trawls (Thallumadi) into light fishing craft targeting Belonids Hemiramphids along Palk Bay. detailed survey was conducted six landing centres mainly targeted catch Tylosurus crocodilus from 2000 0300 hrs at ...

The study was conducted to examine the effect of some socio-cultural practices on fisheries management in Ghana. A case done bottom set gillnet fishery at Apam and Egyaa No.1 Central Region Data were collected through field observations interviews. revealed that male children fishing communities Ghana introduced younger ages ensure continuation family trade. Fishing partnership systems practice...
