By-catch species susceptibilities and potential for survival in Algarve (southern Portugal) deep-water crustacean trawl fishery

Scientia Marina, 2018
Bottom trawling for crustaceans in Portuguese coastal waters is an important fishery in terms of revenue, despite its negative impacts on deep-sea ecosystems.

Decrease in water clarity of the southern and central North Sea during the 20th century [PDF]

, 2015
Light in the marine environment is a key environmental variable coupling physics to marine biogeochemistry and ecology. Weak light penetration reduces light available for photosynthesis, changing energy fluxes through the marine food web.

Toxic Metals in Dried Marine Fish and Implications for Human Health in Bangladesh and Exporting Countries

Food Safety and Health, EarlyView.
This study assessed toxic metals in five dried marine fish species from Bangladesh. Although most metals were within safe limits, chromium (Cr) consistently exceeded FAO/WHO standards, especially at Kuakata Beach. The findings highlight localized contamination hotspots and species‐specific bioaccumulation, while risk assessment supports the safety and ...

Effects of chronic trawling disturbance on the secondary production of suprabenthic and infaunal crustacean communities in the Adriatic Sea (NW Mediterranean)

Ciencias Marinas, 2009
Towing gears are known to produce several kinds of effects on benthic ecosystems. As small organisms and benthic species with faster growth rates and shorter life histories can withstand the fishing mortality and benefit from reduced competition or ...

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

Our shifting perspectives on the oceans [PDF]

, 2003
In the last 15 years new research findings have radically reshaped our understanding of human effects on ocean ecosystems. Here I describe five major shifts in perspective that reveal our impacts to be more severe and persistent than previously ...

Projected Warming of the Southern Ocean Disrupts Embryonic Development and Hatch Timing in Antarctic Fish

Global Change Biology Communications, EarlyView.
Embryos are particularly sensitive to thermal challenge. Antarctic fish embryos raised at projected Southern Ocean temperatures hatch during the winter, have a high incidence of morphological abnormalities, have shorter body lengths, and express genes indicative of cellular stress.

Exploring the degree of trawling disturbance by the analysis of benthic communities ranging from a heavily exploited fishing ground to an undisturbed area in the NW Mediterranean

Scientia Marina, 2011
This study focuses on 4 sites in the northwestern Mediterranean to investigate the response of benthic fauna across a gradient of trawling impact. One site was located in a heavily exploited fishing ground.

Licensed To Kill: A Defense of Vicarious Liability Under the Endangered Species Act [PDF]

, 2014
The Endangered Species Act (ESA) makes it illegal to take an endangered and threatened species by killing, harming, or harassing the animal. Although the classic example of a take is an individual poacher shooting an endangered species, these protected

Translating Ecological Integrity terms into operational language to inform societies

, 2018
It is crucial that societies are informed on the risks of impoverished ecosystem health for their well-being. For this purpose, Ecological Integrity (EI) is a useful concept that seeks to capture the complex nature of ecosystems and their interaction ...
