Effects of experimental in situ seabed disturbance on deep‐sea macrofaunal communities of Chatham Rise, Southwest Pacific

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1422-1459, December 2025.
ABSTRACT With the possibility of deep‐sea mining of mineral resources occurring, it is necessary to understand potential impacts on benthic communities. Previous simulated mining experiments revealed direct benthic impacts; however, indirect impacts of sedimentation are not well understood.

The effect of electric pulse stimulation to juvenile cod and cod of commercial landing size [PDF]

open access: yes, 2011
The first pilot study on the effects of electric pulse stimulation on larger cod carried out in 2008 was based on a single nominal setting of the Verburg-Holland UK153 pulse system with the intention to determine the range of pulse characteristics with ...

Measuring and assessing the physical impact of beam trawling [PDF]

open access: yes, 2016
Beam trawling causes physical disruption of the seabed through contact of the gear components with the sediment and the resuspension of sediment into the water column in the turbulent wake of the gear.

Efficiency changes in bottom trawling for flatfish species as a result of the replacement of mechanical stimulation by electric stimulation [PDF]

open access: yes, 2020
Although fishing with electricity is illegal in the European Union, a number of temporary licences allowed converting beam trawlers to pulse trawling.

Effects of an experimental in situ seabed disturbance on deep‐sea benthic ecosystem function and macro‐infaunal community structure on the Chatham Rise, Southwest Pacific

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1496-1529, December 2025.
ABSTRACT Expansion of extractive industries to deep‐sea environments will lead to increased stresses on seafloor ecosystems. We examined changes in environmental parameters following direct and indirect experimental benthic disturbance using a modified plough on the Chatham Rise (∼450 m water depth), Aotearoa/New Zealand. Measurements included sediment

Defining ecological roles of sharks on coral reefs

open access: yesBiological Reviews, Volume 100, Issue 6, Page 2707-2725, December 2025.
ABSTRACT Sharks have often been perceived to play a critical role in the dynamics of coral reef ecosystems globally. Yet, there is relatively little evidence to support this idea across all but a limited set of species and contexts. Research on the roles and importance of reef sharks has been complicated by logistical challenges in collecting data on ...

The effect of pulse stimulation on marine biota - Research in relation to ICES advice - Progress report on the effects on benthic invertebrates [PDF]

open access: yes, 2009
In response to ecosystem related concerns about bottom trawling and particularly beam trawling that were raised by various scientists in the last decades of the previous century.

Fishing tactics and the effect of resource depletion and interference during the exploitation of local patches of flatfish [PDF]

open access: yes, 2022
The fine-scale exploitation pattern of fishers and the interactions among fishing vessels determine their impact on exploited populations, habitats, and ecosystems. This study used a unique combination of high resolution data of fishing tracks (positions

New approaches to the reduction of non-target mortality in beam trawling [PDF]

open access: yes, 2005
This paper presents experiments with modified beam trawls aimed at reducing discard rates and direct mortality of benthic in-fauna and epi-fauna without affecting the level of landings.

Replacing mechanical stimulation by electrical stimulation reduces environmental impact of the flatfish beam trawl fishery [PDF]

open access: yes, 2021
Beam trawls are widely used in European waters to target flatfish, in particular sole (Solea solea) and produce a substantial amount of discards. Tickler chains used to chase flatfish from the seabed have considerable adverse impacts on the ecosystem ...
