Examining the Impact of Derelict Pots on Blue Crab (Callinectes sapidus) Catch and Harvest Within a Recreational Fishery

Fisheries Management and Ecology, EarlyView.
ABSTRACT Derelict fishing gear can negatively affect marine ecosystems through mortality in coastal environments. This study explored the impact of derelict and active crab pots on recreational blue crab (Callinectes sapidus) catch rates and landings in a Mid‐Atlantic estuary by deploying experimental pots in four habitat strata within three sections ...

Geohazard features of the Aeolian Island slopes and the North-Eastern Sicily offshore

Journal of Maps
The MaGIC project (Marine Geohazard along the Italian Coasts) had the aim of mapping the geohazard in the Italian seas and resulted in the production of numerous maps covering parts of the Italian Seas.

The Nippon Foundation—GEBCO Seabed 2030 Project: The Quest to See the World’s Oceans Completely Mapped by 2030

Geosciences, 2018
Despite many of years of mapping effort, only a small fraction of the world ocean’s seafloor has been sampled for depth, greatly limiting our ability to explore and understand critical ocean and seafloor processes.

A Modified Gear Removal Index (GRI) Method to Support the Management of Abandoned Fishing Gear on Coralligenous Reefs

Fisheries Management and Ecology, EarlyView.
ABSTRACT Abandoned, Lost or otherwise Discarded Fishing Gears (ALDFG) have significant negative effects on marine ecosystems. In the Mediterranean Sea, the impact of ALDFG is particularly relevant on coralligenous reefs. The management of ALDFG focuses primarily on their removal, however this type of intervention may potentially damage the habitat, so ...

Interactive Effects of Elevated Temperature and Moderate Hypoxia on a Shallow‐Water Bivalve, Fulvia mutica

Fisheries Oceanography, EarlyView.
ABSTRACT Amid progressing climate change, this study investigated the interactive effects of water temperature, dissolved oxygen (DO), and shell length on Fulvia mutica, a shallow‐coastal water bivalve, focusing on the combined impacts of elevated temperature and moderate hypoxia.
