Impacts of Pollution, Fishing Pressure, and Reef Rugosity on Resource Fish Biomass in West Hawai‘i [PDF]

open access: yesThe Bulletin of the Ecological Society of America, 2020
AbstractHuman activities and land‐use drivers combine in complex ways to affect coral reef health and, in turn, the diversity and abundance of reef fauna. Here we examine the impacts of different marine protected area (MPA) types, and various human and habitat drivers, on resource fish functional groups (i.e., total fish, herbivore, grazer, scraper ...

Temporal Changes in Microbial Communities Beneath Fish Farm Sediments Are Related to Organic Enrichment and Fish Biomass Over a Production Cycle

open access: yesFrontiers in Marine Science, 2020
The marine fish farming industry is growing at a significant rate, yet a number of concerns still remain with regards to environmental impacts on the surrounding coastal sea and its biota.

LONG-TERM AVERAGE BIOMASS AND DOMINANT FISH SPECIES IN THE BOTTOM BIOTOPES OF THE OKHOTSK SEA. PART 2. COMPOSITION AND QUANTITATIVE RATIO OF SPECIES AT THE CONTINENTAL SLOPE IN DIFFERENT AREAS OF THE SEA

open access: yesИзвестия ТИНРО, 2018
Demersal fish biomass is quantitatively evaluated in the bottom biotopes at the depths to 2000 m at the continental slope of the Okhotsk Sea on the data of 2,545 trawl catches obtained in 1977–2010.

Supplements to the generalized quantitative assessments of benthic macrofauna in the Far Eastern Seas and adjacent waters of the Pacific Ocean. Report 1. Regional features of distribution for biomass of fish

open access: yesИзвестия ТИНРО, 2016
Long-term information on mean annual biomass of the main taxa of bottom and demersal fishes on the shelf and upper continental slope (down to 2025 m) in the Far Eastern Seas and adjacent Pacific waters is summarized.

Fishing destabilizes the biomass flow in the marine size spectrum [PDF]

open access: yesProceedings of the Royal Society B: Biological Sciences, 2011
Fishing impacts on marine food webs are predicted by simulations of a size spectrum community model. In this model, predation is determined by predator and prey size and abundance, and drives predator growth and prey mortality. Fishing amplifies temporal oscillations in the biomass flow.

Vertical diel dynamic of fish assemblage associated with an artificial reef (Northern Adriatic Sea)

open access: yesScientia Marina, 2007
The vertical diel activity of a fish assemblage inhabiting the Senigallia artificial reef (northern Adriatic Sea, Italy) was evaluated from July to November 1996 using enhanced hydroacoustic techniques. Extensive seabed mapping of the area was done using
