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

A hierarchical model to estimate the abundance and biomass of salmonids by using removal sampling and biometric data from multiple locations [PDF]
, 2010 We present a Bayesian hierarchical model to estimate the abundance and the biomass of brown trout (Salmo trutta fario) by using removal sampling and biometric data collected at several stream sections.

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.

Известия 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.

Fermentation, 2021 The rapid growth of aquaculture and the lack of fish meal demand new sustainable ingredients. Although fungal biomass is found to be a promising sustainable fish feed supplementation candidate, the characteristics of this protein-rich source are closely ...

Journal of Marine Science and Engineering, 2022 Spatially explicit information on coral fish species abundance and distribution is required for effective management. Nonextractive techniques, including echosounders and video census, can be particularly useful in marine reserves where the use of ...

Large mesopelagic fishes biomass and trophic efficiency in the open ocean [PDF]
Nature Communications, 2014 With a current estimate of ~1,000 million tons, mesopelagic fishes likely dominate the world total fishes biomass. However, recent acoustic observations show that mesopelagic fishes biomass could be significantly larger than the current estimate. Here we combine modelling and a sensitivity analysis of the acoustic observations from the Malaspina 2010 ...

Polyculture of tilapia (Oreochromis niloticus) and lemeduk (Barbonymus schwanenfeldii) in floating net cages as a strategy for utilizing natural food [PDF]
E3S Web of Conferences, 2022 Polyculture is a sustainable aquaculture system because it can reduce environmental pollution and increase feeding efficiency. The purpose of this study was to analyze the performance of growth, biomass and food competition for tilapia as the main ...
