Impact of Piracy and Sea Robberies on Fishing Business in Nigeria: A Focus on Lagos Coastal Area [PDF]
Revista de Management Comparat International, 2019 Nigeria as a littoral state with a coastline of slightly above 800 kilometers and located in the Gulf of Guinea (GoG) region puts the government in a position that requires her to deploy resources to combat the menace of piracy and sea robbery.

Frontiers in Marine Science, 2022 Submarine canyons are important conduits of sediment and organic matter to deep-sea environments, mainly during high-energy natural events such as storms, river floods, or dense shelf water cascading, but also due to human activities such as bottom ...

Persistence of Biogeochemical Alterations of Deep‐Sea Sediments by Bottom Trawling
Geophysical Research Letters, 2021 Bottom trawling grounds have been expanding to deeper areas of the oceans since the mid‐XXth century, and mitigating strategies aimed to protect fish stocks, such as temporal trawling closures, have recently been implemented.

Limnology and Oceanography Letters, 2020 Bottom trawling and eutrophication are large stressors that are critically coupled. Here we show, using a before‐after control‐effect design, the significant reduction in denitrification as a result of experimental bottom trawling in a shallow coastal ...

Discards of Spanish trawler fleets operating in the Bay of Biscay in 2000
Scientia Marina, 2006 A stratified sampling programme by gear and port was carried out by observers on board vessels in 2000 to study the discard behaviour of trawler fleets operating off Spanish North Atlantic coasts. No relationship between discards in weight or numbers and

Exploitation patterns of Octopus vulgaris in two Mediterranean areas
Scientia Marina, 2002 Exploitation patterns of the common octopus, Octopus vulgaris, in two Mediterranean areas were studied in three ports, two in the Thracian Sea (Greece, Eastern Mediterranean) and one in the Catalan Sea (Spain, Western Mediterranean).

The First Cut Is the Deepest: Trawl Effects on a Deep-Sea Sponge Ground Are Pronounced Four Years on
Frontiers in Marine Science, 2020 Few studies have described the effects of physical disturbance and post-recovery of deep-sea benthic communities. Here, we explore the status of deep-sea sponge ground communities four years after being impacted by an experimental bottom trawl.

Distribution of Bottom Trawling Effort in the Yellow Sea and East China Sea. [PDF]
PLoS ONE, 2016 Bottom trawling is one of the most efficient fishing activities, but serious and persistent ecological issues have been observed by fishers, scientists and fishery managers. Although China has applied the Beidou fishing vessel position monitoring system (

Frontiers in Marine Science, 2017 Bottom-trawling fisheries are a common threat to the health of continental margins worldwide. Together with numerous environmental and biological processes, physical disturbance induced by trawlers can largely shape the benthic habitats and their ...
