Warmer and browner waters decrease fish biomass production. [PDF]
Glob Chang Biol, 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 ...

Swimbladder morphology masks Southern Ocean mesopelagic fish biomass. [PDF]
Proc Biol Sci, 2019 Within the twilight of the oceanic mesopelagic realm, 200–1000 m below sea level, are potentially vast resources of fish. Collectively, these mesopelagic fishes are the most abundant vertebrates on Earth, and this global fish community plays a vital role in the function of oceanic ecosystems.

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

Rio Doce Acoustic Surveys of Fish Biomass and Aquatic Habitat. [PDF]
Integr Environ Assess Manag, 2020 Abstract Following the failure of the Fundão mine tailings dam in Brazil, approximately 32 million cubic meters of Fe ore tailings were released into the downstream riverine system. The postevent monitoring surveys implemented the use of noninvasive acoustic methods to improve the understanding of the fish biomass distribution patterns ...

Coral cover a stronger driver of reef fish trophic biomass than fishing [PDF]
Ecological Applications, 2020 Abstract An influential paradigm in coral reef ecology is that fishing causes trophic cascades through reef fish assemblages, resulting in reduced herbivory and thus benthic phase shifts from coral to algal dominance. Few long‐term field tests exist of how fishing affects the trophic structure of coral reef fish assemblages, and how ...

Reduced fish diversity despite increased fish biomass in a Gulf of California Marine Protected Area. [PDF]
PeerJ, 2020 Multi-use marine protected areas (MUMPAs) are a commonly applied tool for marine conservation in developing countries, particularly where large no-take reserves are not socially or politically feasible. Although MUMPAs have produced benefits around the world, the persistence of moderate fishing pressure reduces the likelihood of ...

MODELING FISH BIOMASS STRUCTURE AT NEAR PRISTINE CORAL REEFS AND DEGRADATION BY FISHING [PDF]
Journal of Biological Systems, 2012 Inverted biomass pyramids (IBPs) seem to be extremely rare in natural communities. Until recently, the only examples have been in freshwater and marine planktonic communities. In 2002 and 2008, investigators documented inverted biomass pyramids for nearly pristine coral reef ecosystems within the NW Hawaiian islands and the Line Islands, where apex ...

Fish Oil and Fish Meal Production from Urban Fisheries Biomass in Japan [PDF]
Sustainability, 2020 Finding an alternative feed source for the replacement of fish oil (FO) and fish meal (FM) produced from whole fish has been an important issue for realizing sustainable aquaculture. In this study, fishery by-products generated in the distribution phase, known as urban fisheries biomass (UFB), were focused on.

Estimating biomass, fishing mortality, and “total allowable discards” for surveyed non-target fish [PDF]
ICES Journal of Marine Science, 2014 Abstract Demersal fisheries targeting a few high-value species often catch and discard other “non-target” species. It is difficult to quantify the impact of this incidental mortality when population biomass of a non-target species is unknown.
