Improvement of fish length estimates for underwater visual census of reef fish biomass

Journal of Applied Ichthyology, 2015
Summary Accuracy and precision are of great importance in the assessment of reef fish biomass when conducting an underwater visual census (UVC). Quantification and subsequent correction of the bias is required in order to standardize the estimates and correct for underwater distortion.

Zooplankton biomass and fish production in the Adriatic

2000
Trophic relations in the pelagic ecosystem include phytoplankton as the producers, hebivorous zooplankton as primary consumers; carnivorous and omnivorous zooplankton and larval nekton as secondary consumers. Tertiary consumers, fish and cephalopods, are most exclusively carnivorous.

Biomass and productivity of fishes in estuaries: a South African case study

Journal of Fish Biology, 2016
Estuaries are well known for their role as nutrient and detrital sinks that stimulate high levels of both primary and secondary production which, in turn, support a large biomass of fishes per unit area. This study reviews available information on coastal fish biomasses (g m−2 wet mass) and productivity (g m−2 wet mass year−1) in order to place South ...

A comparison of the fish biomass flow to fish, fisheries, and mammals in six marine ecosystems

1991
Various data sources are used to derive the biomass flow from fish to the fish themselves, to fisheries, and to marine mammals in six ecosystems: Eastern Bering Sea, Norwegian coast and Barents Sea, North Sea, Benguela current, Georges Bank, and Balsfjorden. The largest proportion of fish biomass provides food for the fish themselves in all areas.
