Sampling a Littoral Fish Assemblage: Comparison of Small-Mesh Fyke Netting and Boat Electrofishing [PDF]

open access: yes, 2007
We compared small-mesh (4-mm) fyke netting and boat electrofishing for sampling a littoral fish assemblage in Muskegon Lake, Michigan. We hypothesized that fyke netting selects for small-bodied fishes and electrofishing selects for large-bodied fishes ...

Natural and synthetic microfibers alter growth and behavior in early life stages of estuarine organisms

open access: yesFrontiers in Marine Science, 2023
Increasing shares of microfibers are being detected in environmental samples and a closer look to identify the risk associated with them using ecologically relevant endpoints, especially at sensitive early life stages, is needed.

The enlargement of the Suez Canal and introduction of non-indigenous species to the Mediterranean Sea [PDF]

open access: yes, 2015
The Suez Canal is one of the most important waterways in the world – during the last year 17,148 ships passed through the Canal – reducing emissions, saving time, and operating costs to shippers. The rapid increase in ship size from the “Post-Suezmax” (>

Atherinella blackburni (Schultz, 1949) at Itamambuca Beach, Ubatuba, SP: ecological characterization and distribution on the Brazilian coast (Teleostei: Atheriniformes: Atherinopsidae)

open access: yesBrazilian Journal of Biology
Atherinella blackburni is a silverside species whose occurrence on the Brazilian coast was not properly registered until recently. So far, records of its distribution along the Brazilian shore were limited to Itaparica Island, Bahia State, and Porto ...

Unscreened water-diversion pipes pose an entrainment risk to the threatened green sturgeon, Acipenser medirostris. [PDF]

open access: yes, 2014
Over 3,300 unscreened agricultural water diversion pipes line the levees and riverbanks of the Sacramento River (California) watershed, where the threatened Southern Distinct Population Segment of green sturgeon, Acipenser medirostris, spawn.

Dynamic blinking in the head of hardyhead silverside fish [PDF]

open access: yesJapanese Journal of Applied Physics, 2021
Abstract Dynamic light reflection can be used to provide an efficient tool for biological sensing of micro and nano-organisms. It is therefore interesting that evidence of dynamic light reflection can also be found in the animal kingdom and that there may be alternative methods of light control actuation.

Prioritising research on endocrine disruption in the marine environment: a global perspective

open access: yesBiological Reviews, EarlyView.
ABSTRACT A healthy ocean is a crucial life support system that regulates the global climate, is a source of oxygen and supports major economic activities. A vast and understudied biodiversity from micro‐ to macro‐organisms is integral to ocean health.

Negative Effects of Diurnal Changes in Acidification and Hypoxia on Early-Life Stage Estuarine Fishes

open access: yesDiversity, 2020
Estuaries serve as important nursery habitats for various species of early-life stage fish, but can experience cooccurring acidification and hypoxia that can vary diurnally in intensity. This study examines the effects of acidification (pH 7.2−7.4)
