Optimizing zebrafish rearing−Effects of fish density and environmental enrichment [PDF]

Frontiers in Behavioral Neuroscience, 2023
IntroductionDespite its popularity in research, there is very little scientifically validated knowledge about the best practices on zebrafish (Danio rerio) husbandry, which has led to several facilities having their own husbandry protocols.

Fish Stocks Around the Gezhouba and Their Response During Fishing Moratorium in the Yangtze River, China [PDF]

Nature Environment and Pollution Technology, 2021
To explore the impact of the fishing moratorium on fish stocks, some parameters and environmental factors were monitored downstream of Gezhouba Dam in April, June and August of 2013. Fish density and target length were get using hydro-acoustics (DIDSON).

Exploring the Drivers of Spatiotemporal Patterns in Fish Community in a Non-Fed Aquaculture Reservoir

Diversity, 2023
Non-fed aquaculture is an important contributor to low environmental impact protein production. However, knowledge of spatiotemporal patterns of the fish community in non-fed fishery systems remains limited, despite their ecological importance for ...

How do natural changes in flow magnitude affect fish abundance and biomass in temperate regions? A systematic review

Ecological Solutions and Evidence, 2023
We conducted a systematic review on the impacts of natural causes of variation or changes in flow magnitude (resulting from climatic variability and broad‐scale drivers such as climate‐induced change) on fish abundance and biomass in temperate regions ...

Effects of Lake Productivity on Density and Size Structure of Pelagic Fish Estimated by Means of Echosounding in 17 Lakes in Southeast Norway

Sensors, 2021
Density estimation of pelagic fish was performed by means of single beam echosounding in 17 lakes within a period of 34 years, from 1985 to 2018. Surveys were performed repeatedly (two to fourteen times) in five lakes.

The effect of various stocking densities on growth performance of Arabian yellowfin seabream (Acanthopagrus arabicus) cultivated in cages at Basrah province

المجلة العراقية للاستزراع المائي, 2021
The effect of various stocking densities (20, 30, 40 fish/m3) on the final weight, weight gain, specific growth and daily growth rates in Arabian yellowfin seabream (Acanthopagrus arabicus) reared in floating cages (2m3) was studied.

Stress responses of juvenile matrinxã (Brycon amazonicus) after transport in a closed system under different loading densities Respostas de estresse de matrinxã (Brycon amazonicus) juvenil após transporte em sistema fechado sob diferentes densidades de carga

Ciência Rural, 2008
Optimum loading density for the transport of matrinxã juveniles was investigated in a closed system with plastic bags. Transport was conducted for 4 h with fish (23.5± 0.4g and 11.6 (0.08cm) starved for 24h at loading densities of 83g L-1 (D1 ...
