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,

The Fish Funnel: A Trawl Modification to Reduce Fish Escapement [PDF]
, 1989 In the Gulf of Mexico there is a need to assess the potential of underutilized fish resource stocks before a commercial fishery develops. Standard sampling trawls used in the Gulf are ineffective for sampling the resource, so larger, high opening, bottom

Sampling effort to characterize estuarine macroinfaunal communities in patchy habitats
Limnology and Oceanography: Methods, EarlyView.Abstract Estuarine benthic macroinfauna have aggregated, patchy distributions, making accurate community measurements dependent upon sampling scales. The purpose of this study is to determine the appropriate core sizes and sampling effort needed to characterize benthic infaunal communities in Corpus Christi Bay, Texas, USA.

Particle sources and transport in stratified Nordic coastal seas in the Anthropocene
Elementa: Science of the Anthropocene, 2018 Particles of all origins (biogenic, lithogenic, as well as anthropogenic) are fundamental components of the coastal ocean and are re-distributed by a wide variety of transport processes at both horizontal and vertical scales.

People and Nature, EarlyView.Abstract This study critically analyses the main narratives surrounding the Atlantic blue crab (Callinectes sapidus) in the Lagoon of Venice. We used a mixed‐method approach, performing a qualitative discourse analysis on a sample of 68 textual sources to identify the narratives across two sectors in the management of the case study: media and politics,

Observations of the 1992 U.S. Pelagic Pair Trawl Fishery in the Northwest Atlantic [PDF]
, 1994 Pelagic pair trawling for tuna, Thunnus spp., and swordfish, Xiphias gladius, was introduced in U.S. Northwest Atlantic waters in 1991. During autumn (October-November) of 1992 under the authority oft he Federal Atlantic Swordfish Regulations, the ...

Rapidly declining seagrass meadows in Brazil: Findings from satellite imagery and local knowledge
People and Nature, EarlyView.Abstract Due to the limitations of individual monitoring approaches, integrating social perceptions with multiple advanced technologies provides a new opportunity to gain a comprehensive understanding of ecosystem degradation. We combined historical aerial mapping, satellite imagery, semi‐structured interviews with local stakeholders, and a bilingual ...
