Effect of water temperature and fish biomass on environmental DNA shedding, degradation, and size distribution [PDF]
Ecology and Evolution, 2019 Environmental DNA (eDNA) analysis has successfully detected organisms in various aquatic environments. However, there is little basic information on eDNA, including the eDNA shedding and degradation processes.

Large recovery of fish biomass in a no-take marine reserve. [PDF]
PLoS ONE, 2011 No-take marine reserves are effective management tools used to restore fish biomass and community structure in areas depleted by overfishing. Cabo Pulmo National Park (CPNP) was created in 1995 and is the only well enforced no-take area in the Gulf of ...

Warmer and browner waters decrease fish biomass production [PDF]
Global Change Biology, 2019 AbstractClimate change studies have long focused on effects of increasing temperatures, often without considering other simultaneously occurring environmental changes, such as browning of waters. Resolving how the combination of warming and browning of aquatic ecosystems affects fish biomass production is essential for future ecosystem functioning ...

Reservoir ecosystems support large pools of fish biomass. [PDF]
Sci Rep, 2023 Abstract Humans increasingly dominate Earth’s natural freshwater ecosystems, but biomass production of modified ecosystems is rarely studied. We estimate potential fish total standing stock in USA reservoirs is 3.4 billion (B) kg, and approximate annual secondary production is 4.5 B kg y −1

Comparison of fish biomass and fish carbon content associated with reef sites at the Rio Grande Valley artificial reef in the Gulf of Mexico. [PDF]
PLoS ONEAs global fisheries stocks have decreased due to overfishing and climate change, artificial reefs have gained significant attention. In addition to providing or restoring habitat, artificial reefs may serve as carbon capture sinks and potential climate ...

A century of fish biomass decline in the ocean [PDF]
Marine Ecology - Progress Series, 2014 We performed a global assessment of how fish biomass has changed over the last 100 yr, applying a previously developed methodology using ecological modeling. Our assessment built on more than 200 food web models representing marine ecosystems throughout the world covering the period from 1880 to 2007.

Estimation of Fish Biomass Using Environmental DNA
PLoS ONE, 2012 Environmental DNA (eDNA) from aquatic vertebrates has recently been used to estimate the presence of a species. We hypothesized that fish release DNA into the water at a rate commensurate with their biomass. Thus, the concentration of eDNA of a target species may be used to estimate the species biomass.

From environment to biomass: trait-mediated effects on submerged macrophyte biomass in a subtropical shallow restored lake [PDF]
BMC Plant BiologyBackground Recovery of submerged macrophyte communities is crucial for the restoration of shallow eutrophic lakes, as macrophyte biomass here plays a key role in maintaining a clear-water state.
