Benthic Indicators for Monitoring Bottom‐Trawl Fishing Impacts [PDF]

open access: yesThe Bulletin of the Ecological Society of America
There is increasing interest in developing indicators to assess the state of benthic communities in shelf seas primarily affected by bottom trawling. Yet, many indicators have been developed in specific geographic regions making it difficult to determine their broader applicability.

Biogeochemical dynamics in a marine storm demonstrates differences between natural and anthropogenic impacts

open access: yesScientific Reports
This study explores the impact of a wind storm on sediment resuspension and marine biogeochemical dynamics. Additionally, the storm took place during an expedition researching bottom trawling, enabling the direct comparison of certain natural and ...

Estimating Patagonian toothfish (Dissostichus eleginoides) length at first maturity from their age, sex and temperature experience around South Georgia

open access: yesJournal of Fish Biology, EarlyView.
Abstract Patagonian toothfish (Dissostichus eleginoides) are a long‐lived, slow‐growing deep‐sea species endemic to the Southern Hemisphere and the focus of longline fisheries managed to ensure sustainable exploitation. Managing the fisheries relies on accurate stock assessments that include pertinent biological and exploitation processes.

An investigation into the diet of elephant fish (Callorhinchus milii) in the waters of Aotearoa/New Zealand

open access: yesJournal of Fish Biology, EarlyView.
Abstract Chondrichthyans (sharks, rays and chimaeras) are increasingly understood to be an important part of ocean ecosystems, but their ecological role is unclear. Callorhinchus milii (elephant fish) is a chimaera species endemic to Aotearoa/New Zealand and southern Australian waters.

Modified fin morphology in mackerel icefish (Champsocephalus gunnari) may indicate nesting behaviour

open access: yesJournal of Fish Biology, EarlyView.
Abstract Monitoring reproductive traits in Southern Ocean species is challenging. Males in some channichthyids thicken the epithelium along their anal fins to aid nest construction. This study presents initial evidence that the only commercially harvested channichthyid, mackerel icefish (Champsocephalus gunnari), exhibits modifications to their anal ...

Escapement of gadoid fish beneath a commercial bottom trawl: Relevance to the overall trawl selectivity

open access: yesFisheries Research, 2006
Escapement of Atlantic cod (Gadus morhua), haddock (Melanogrammus aeglefinus) and saithe (Pollachius virens) beneath a commercial bottom trawl, rigged with a 60 cm diameter rockhopper gear, was studied in the Barents Sea. The study was performed off the coast of north Norway in March/April 2003.

Early‐life temperature drives recruitment success in Eurasian perch (Perca fluviatilis) populations

open access: yesJournal of Fish Biology, EarlyView.
Abstract Interannual fluctuations in the abundance of young‐of‐the‐year (YOY) European perch (Perca fluviatilis) were studied in two large French peri‐alpine lakes using a 12‐year dataset of late summer hydroacoustic surveys. Previous research has highlighted the importance of temperature.

Effects of chronic bottom trawling on soft-seafloor macrofauna in the Kattegat

open access: yesMarine Ecology Progress Series, 2018
: Chronic impact studies of bottom trawling aiming to reveal long term effects on 22 benthic organisms are often hampered by the lack of comparable untrawled conditions and the 23 difficulty to assess the spatial distribution of trawling intensity.
