Modified sorting technique to mitigate the collateral mortality of trawled school prawns (Metapenaeus macleayi) [PDF]
, 2009 The potential for changes to onboard handling practices in order to improve the fate of juvenile school prawns (Metapenaeus macleayi) discarded during trawling were investigated in two Australian rivers (Clarence and Hunter) by comparing a purpose-built,

A Scenario Tool for Sustainability Transformation in Fisheries and Beyond
Sustainable Development, EarlyView.ABSTRACT The urgency to find sustainable management solutions intensifies with increasing natural resource scarcity. Resource sectors are usually characterized by diverse resource users. We developed a structured scenario tool designed to quantitatively assess policy options for achieving sustainability, accounting for ecological, economic and ...

Ciencias Marinas, 2009 Towing gears are known to produce several kinds of effects on benthic ecosystems. As small organisms and benthic species with faster growth rates and shorter life histories can withstand the fishing mortality and benefit from reduced competition or ...

Ontogeny of foraging behaviour in an opportunistic gull inhabiting urban marine ecosystems
Wildlife Biology, EarlyView.Urbanization affects ecosystems by reducing biodiversity and displacing species from native habitats. While some suffer, others, like urban wildlife, adapt through innovative feeding and behaviours that improve their fitness in human‐altered settings. Despite research on wildlife in urban areas, the development of foraging behaviour in urban species is

Urban bats show dietary flexibility in aquatic arthropod consumption at urban and rural waterbodies
Wildlife Biology, EarlyView.Urban waterbodies are critical for biodiversity and provide feeding grounds for insectivorous bats. Yet, how urbanisation affects bats' food choices at urban waterbodies and the role of emergent aquatic arthropods remain poorly understood. We compared the diet of three urban bat species – Vespadelus vulturnus, Chalinolobus gouldii,and Myotis macropus –

Frontiers in Marine Science, 2015 In large rivers, such as the Danube, standardized and representative sampling of fish is still problematic. Until now, night time shoreline electrofishing proved to be the most comprehensive fish assessment method, however, it is not suitable for ...

Improved trawling setup for sampling pelagic juvenile fish communities in small inland bodies of water [PDF]
Acta Ichthyologica et Piscatoria, 2018 Trawling juveniles is an effective method to estimate 0+ fish assemblages in inland bodies of water. Trawlers are usually moved between bodies of water by ground transport, which restricts the size, weight and type of the equipment able to be transported,

EFFECTS OF TOWED DEMERSAL FISHING GEAR ON BIOGENIC SEDIMENTS: A 5-YEAR-STUDY [PDF]
, 2000 Experimental scallop fishing was carried out using towed commercial dredges on sediments deposited by unattached coralline algae in order to quantify their sensitivity to damage from current fishing practices.
