Design criteria for rotating flow cells in rectangular aquaculture tanks
This work analyzes the simplest inlet and outlet configurations that create homogeneous rotating flow cells in rectangular aquaculture tanks, in order to combine the advantages of rectangular and…
Influence of growing conditions on Ulva ohnoi composition cultivated in an IMTA-RAS system
- Ingrid Masaló Llorà, J. Baradad, J. Ferrer, J. C. Ugarte, J. P. Valverde, P. D. Ridder
- Biology, Engineering
Among Integrated Multitrophic Aquaculture (IMTA) techniques, the integration of fish and macroalgae cultures in Recirculating Aquaculture Systems (IMTA-RAS) is currently one of the most promising…
Evaluation of spatial distribution of flatfish by laser scannig
Introduction Fish distribution in a tank is a reliable indicator of culture conditions. In one side, the distribution of fish reflects water quality gradients in the tank or preferential areas…
Computerized imaging techniques for fish tracking in behavioural studies
Distribution of velocities in aquaculture circular tanks with rotating flow and evaluation of uniformity
Control of velocities in aquaculture tanks is very important, since fish need certain velocities for maintaining general health and also a minimum veloc ity is needed to eliminate biosolids. In…
Modeling and optimization of flow pattern in tanks for seaweed culture
This study analyzes the flow pattern in tanks for seaweed culture and finds that seaweeds are usually tumbled (mixed) by vigorous bottom aeration.
Manipulating Ulva-associated bacterial communities: a possible strategy for bacterial control in IMTA-RAS cultures?
- J. P. Valverde, Patricia Ruiz, J. Baradad, Ingrid Masaló Llorà, P. D. Ridder, J. C. Ugarte
- Environmental Science
As epibiotic communities in macroalgae may be randomly formed by functionally equivalent guild members present in the surrounding seawater, we hypothesize that experimental colonization of Ulva…
Study of consecutive resuspension and sedimentation processes in aquacultural biosolids using an oscillating grid
Biosolids maintenance in the column depends on the turbulence present in the tank, which will depend on the culture conditions (fish swimming activity) and tank design (geometry and water inlet conditions).
Evaluation of sole (Solea senegalensis) preferences for different substrate textures and colours
A higher occurrence of Black Patch Necrosis, a significant increase in metabolic rate, and even pigmentation abnormalities have been attributed to sand deprivation in flatfishes kept on hard-bottomed tanks without sand.
